Instead of sending you Technical Supplements for any changes in the Technical Manual
as we previously did, we will send you new or updated pages to be inserted into the
current manual. Just replace any obsolete pages with the updated pages, and add any
new pages in the appropriate place in the binder. Enclosed with this bulletin is Revision
2 of Pages 3-9 and 3-10. To avoid confusion, be sure to discard any obsolete revisions
of any page.
To make sure that your manual has the latest revision for each page, a Table of
Contents page will be issued with any revision to the Technical Manual. The Table of
Contents lists each page number, the contents of the page, the latest revision number
for the page, and the date that the revision was implemented. The date of the last
revision to the Table of Contents can be found in the lower right corner of the page.
Since this is the first change to the Technical Manual since it was issued in November,
this is the first Table of Contents to be issued. Add this new Table of Contents right
after the Title Page (before the divider page for "GENERAL"). Any subsequent changes
to the manual will be accompanied by the appropriate new or updated pages and a
revised Table of Contents.
2. New Engineer and Architect Specification Sheet
Pyro Chem has developed a new Engineer and Architect Specification sheet for the Wet
Chemical Restaurant Kitchen Fire Suppression System. This sheet gives a suggested

301 Division Street 201-335-9750
Boonton, New Jersey 07005 FAX 201-335-0253
specification for a fire suppression system to protect restaurant kitchen equipment, and
explains how Pyro Chem's system operates. This updated version refers to the new
UL-300 testing standard, and may be useful in persuading specification writers to
require UL-300 be enforced at their new installations. This will help win jobs away
from unauthorized distributors selling used equipment. It is also an excellent tool for
explaining Pyro Chem's system to Code Enforcement Officials, Fire Inspectors, and end
users. Restaurant owners may use it to help explain the operation of the system to
their employees. A sample is included with this bulletin, and more are available upon
request. Just ask your District Sales Manager or one of our Customer Service
Representatives, and we will ship some with your next order.
3. Introduction of Stainless Steel Wire Crimps
Pyro Chem is introducing stainless steel wire crimps for high temperature applications.
Anyone who has had a false discharge because of a wire crimp releasing will appreciate
this item. Aluminum crimps will begin to lose strength under heat (called annealing)
between 350°F and 400°F, and will melt completely at around 500°F. The copper
crimps will hold up better (annealing will begin at around 700°F), but they will weaken
at lower temperatures over time when under tension. The stainless steel crimps will
anneal at approximately 1700°F, and I recommend them for use with every FL-500
thermal detector. However, if FLH-1 Fusible Link Hangers are used, no crimps are
required (except at the terminal link), and the steel hangers will withstand the high
temp era tures.
These new wire crimps are sold in packages of ten, and ordering information is as
follows:
Model Number Suggested User Net Price
WC-10SS (10 per package) $10.00
4. Changes at Pyro Chem
As we mentioned in the last UL-300 Update, Pyro Chem is in the midst of an aggressive
UL-300 PCL-Series enhancement program. The changes listed in this bulletin are just
the tip of the iceberg! We are currently testing to improve our coverage on several
appliance, and we expect to have some better coverages as early as the spring. Keep
on the lookout for subsequent bulletins that will outline these changes.
If you have called Pyro Chem recently to place an order or get technical information,
you probably noticed our new phone system. Under the old system too many phone
messages were lost, and an electrical storm would wipe out the phones (and our
customers!) temporarily. The new system will direct your call straight to the person
you need to speak with, with the option of leaving a message right on their phone.
Now, when you call Pyro Chem just follow the instructions to direct your call to the
correct person. You can also reach that person by dialing the correct extension
number. The following is a list of numbers you will probably use most:

Customer service
3 Technical assistance Mark Pavlica
105 Credit \ Accounts Receivable Laura MacLauchlan
108 Invoice questions Pat Harodetsky
101 Sales Manager Ed Balogh
103 General Manager Jack Dortch
However, for those of you who like to speak to real people, just dial "0" to get the
operator. The operator can direct your call to the correct party. Remember that your
District Sales Manager can be reached directly by dialing 1-800-797-6243 or 1-800-

Genera/
The Pyro Chem Restaurant Kitchen Fire Suppression System is a
pre-engineered solution to appliance and ventilating hood and
duct grease fires. The system is designed to maximize hazard
protection, reliability, and installation efficiency. Automatic or
manual system activation releases a throttled discharge of
potassium carbonate solution on the protected area in the form of
fine droplets to extinguish the fire and prevent reignition after the
discharge is complete.
System Operation
The Pyro Chem Restaurant Kitchen Fire Suppression System has
been designed for protecting kitchen hood, plenum, exhaust duct,
grease filters, and cooking appliances (such as fryers, griddles,
rangetops, upright broilers, charbroilers and woks) from grease
fires. The versatile state-of-the-art wet chemical distribution
technique, combined with dual, independent activation capability -
automatic fusible link or manual release - provides efficient,
reliable protection the moment a fire is detected. Once initiated,
the pressurized wet chemical extinguishing agent cylinder expels
a potassium carbonate solution through a pre-engineered piping
network and out the discharge nozzles. The wet chemical
discharge pattern is maintained for a duration of time to ensure
extinguishment and inhibit regnition.

CHAPTER I
General Information
INTRODUCTION
The Pyro Chem, Inc. Restaurant Fire Suppression System is of the pre-
engineered type as defined by NFPA-17A Standard for Wet Chemical
Extinguishing Systems and is designed to provide fire protection for
restaurant cooking appliances, hoods, and ducts. Installation and
maintenance of the system must conform to the limitations detailed in this
manual and be performed by an Authorized Pyro Chem, Inc. dealer.
The Pyro Chem, Inc. System utilizes a wet chemical agent specifically
designed to suppress restaurant cooking area fires. The system provides
automatic actuation and can be manually actuated through a remote
mechanical pull station. Upon actuation, the system discharges a pre-
determined amount of agent to the duct, plenum, and cooking appliances.
The agent acts to suppress fires in three ways:
1.The chemical chain reaction causing combustion is interrupted by both
the agent itself and the resulting steam formation.
2. The agent cools the fire bringing it below auto -ignition temperature.
3. The agent reacts with hot grease forming a soap -like layer
saponification) that helps prevent the escape of combustible vapors, thus
preventing re -ignition.
The shutdown of fuel and power to all appliances under protected
ventilation equipment is required upon system actuation. The shutdown
of make-up or supply air is recommended upon system actuation but is
not required. Exhaust fan(s) in the ventilation system should remain on
during system discharge as they assist the dispersion of chemical through
the ventilating system. The system is UL Listed with or without exhaust
fan shutdown.
TEMPERATURE LIMITATIONS
The operating temperature range of the Pyro Chem, Inc. System is 320 F.
0' C.) minimum to 120' F. (49' C.) maximum.
UL LISTING
The Pyro Chem, Inc. Restaurant Fire Suppression System has been tested

the PCL-240 and PCL-350 respectively. The PCL-550
requires two (2) RL-275 charges.
CAUTION
Precautions must be taken when handling and
transferring wet agents as they are caustic in nature.
Goggles must be worn at all times. If any agent gets
into the eyes, they should be flushed with clean water
for 15 minutes and a physician contacted. If any agent
contacts the skin, it should be flushed with cold water
to prevent irritation. The agent is electrically
conductive. Care must be taken to thoroughly clean up
any agent discharged around electrical appliances
before turning the power on.
After system discharge, agent must be cleaned up
immediately with hot, soapy water to prevent corrosion of
effected surfaces.

CHAPTER III
System Design
This section will cover the proper design of the Pyro Chem Res-
taurant Fire Suppression System. It is divided into four (4) sections:
1. Nozzle Coverage and Placement.
2. Cylinder Sizing.
3. Piping Limitations.
4. Detector Requirements.
Each of these sections must be completed before
attempting any installation.
Nozzle Coverage and Placement
This section will provide guidelines for determining nozzle
type, positioning, and quantity for duct, plenum, and
appliance protection.
A. Duct Protection
The following three (3) nozzles have been developed for
the protection of exhaust ducts:
1. Model NL-P.
2. Model NL-D2.
3. Model NL-D3.
Each nozzle is approved for use with the exhaust fan dampered,
undampered with the fan on, or undampered with the fan off. It
is not required that the fan be shut down or the exhaust duct be
dampered for the system to operate properly. Each nozzle is
approved to protect exhaust ducts of unlimited length.
1. Model NL-P.
The Model NL-P nozzle is a one (1) flow point nozzle
designed for the protection of exhaust ducts. One (1) or
two (2) Model NL-P nozzles can be used on a single duct
branch.
A single Model NL-P exhaust duct nozzle can protect a square
or rectangular duct with a maximum perimeter of 50 inches
and a maximum one -side length of 17 inches. It can also
protect a round duct with a maximum circumference of 50
inches and a maximum diameter of 16 inches (see Figure 3-1)
The nozzle must be installed on the centerline of the duct and
aimed directly into the duct opening (see Figure 3-2).
Two (2) Model NL-P exhaust duct nozzles can protect a
square or rectangular duct with a maximum perimeter of
84 inches and a maximum one -side length of 34 inches.
They can also protect a round duct with a maximum
circumference of 84 inches and a maximum diameter of
26.5 inches. When two (2) Model NL-P nozzles are used to
protect a single duct, the cross sectional area of the duct
must be divided into two equal symmetrical areas. The
nozzle must then be installed on the center line of the area
it protects and aimed directly into the duct opening (see
Figure 3-2.1).
2. Model NL-D2.
The Model NL-D2 nozzle is a two (2) flow point nozzle
designed for the protection of exhaust ducts. Only one (1)
Model NL-D2 nozzle can be used on a single duct branch.
A single Model NL-D2 exhaust duct nozzle can protect a
square or rectangular duct with a maximum perimeter of
75.5 inches and a maximum one -side length of 25 inches.
It can also protect a round duct with a maximum circum-
ference of 75.5 inches and a maximum diameter of 24
inches (see Figure 3-1). The nozzle must be installed on
the centerline of the duct and aimed directly into the duct
opening (see Figure 3-2).
3. Model NL-D3.
The Model NL-D3 nozzle is a three (3) flow point nozzle
designed for the protection of exhaust ducts. One (1) or two
2) Model NL-D3 nozzles can be used on a single duct branch.
A single Model NL-D3 exhaust duct nozzle can protect a
square or rectangular duct with a maximum perimeter of
100 inches and a maximum one -side length of 33 inches.
It can also protect a round duct with a maximum circum-
ference of 100 inches and a maximum diameter of 31.75
inches (see Figure 3-1)
The nozzle must be installed on the centerline of the duct
and aimed directly into the duct opening (see Figure 3-2).
Two (2) Model NL-D3 exhaust duct nozzles can protect a
square or rectangular duct with a maximum perimeter of 150
inches and a maximum one -side length of 66 inches. They
can also protect a round duct with a maximum circumference
of 150 inches and a maximum diameter of 47.5 inches. When
two (2) Model NL-D3 nozzles are used to protect a single duct,
the cross sectional area of the duct must be divided into two
equal symmetrical areas. The nozzle must then be installed
on the centerline of the area it protects and aimed directly
into the duct opening (see Figure 3-2.1).

B. Plenum Protection
The Model NL-A nozzle is a one (1) flow point nozzle that
MAXMAX has been developed to protect the plenum section of theI50'
exhaust hood. Only one (1) Model NL-A nozzle can be
used on a single plenum branch. A single Model NL-A can
protect a plenum (with single or V-Bank filters) with
rectangular dimensions of 8' x 4' or less. Larger plenums
can be protected by dividing the hazard area so that each
nozzle protects an area of 8' x 4' or less (see Figure 3-3).
The nozzle(s) must be located at the center of the V-Bank
width or centered between the filter width when used with
a single bank filter plenum. -It must be within 4" of the wall
it is mounted against (see Figure 3-4), or within 4" of the
edge of the protected zone.

SECTION 2
Cylinder Sizing
After determining the number and type of nozzles required
to protect the duct, plenum, and cooking appliances, the
total number of system flow points can be determined.
The sum of all required nozzles' flow points is used to
determine the size and quantity of cylinders required.
MAXIMUM CYLINDER FLOW POINTS
Flow Points Cylinder
8 PCL-240
13 PCL-350
20 PCL-550
For systems requiring more than twenty (20) flow points,
any combination of cylinders can be used provided the
total flow point requirements are met.
EXAMPLE
If a system requires twenty-six (26) flow points, the
following combinations of cylinders can be used:
1. 1 x PCL-550 and 1 x PCL-240 (28 FP total)
2. 2 x PCL-350 (26 FP total)
NOTE:
Cylinders cannot be manifolded together. Each
cylinder must be piped separately.
SECTION 3
Piping Limitations
Pyro Chem Restaurant Fire Suppression System piping
limitations are divided into two categories; Main Supply
Line Piping Limitations and Branch Line Piping
Limitations.
1. Main Supply Line Piping.
The main supply line is a run of pipe from the cylinder to
the hazard area. In general, it is a straight run of pipe that
runs through tees. Branch piping is connected to the side
outlet of these tees.
The main supply line of the Pyro Chem Restaurant Fire
Suppression System utilizes either straight line or split
piping to simplify system installation.
Straight line piping is distinguished by the fact that the
main supply line is a straight run of pipe that flows
through tees. When straight line piping is used, the main
supply line cannot run into the branch of a tee.
Split piping is distinguished by the fact that the main
supply line runs into the branch of the first tee, splitting
the main supply line in two. The main supply line can only
be split once (as described above). When split piping is
used, no branch piping can be connected to the main
supply line before it is split. In split piping systems, the
entire main supply line, including both sides of the split,
cannot exceed the piping limitations outlined in this
chapter. In addition, the equivalent lengths of the main

supply line must be balanced to within +/-10% on either
side of the splitting tee. The difference in flow points on
each side of the splitting tee cannot exceed one flow
point.
2. Branch Line Piping.
Branch piping is used to connect the discharge nozzles to
the main supply line. This piping is connected to the side
outlet of main supply line tees. The last branch is
connected to an elbow at the end of the main supply line.
There are seven (7) types of branch piping:
1. One (1) Nozzle Duct Branch.
2. Two (2) Nozzle Duct Branch.
3. One (1) Nozzle Plenum Branch.
4. One (1) Nozzle Appliance Branch.
5. Two (2) Nozzle Appliance Branch.
6. Three (3) Nozzle Appliance Branch.
7. Four (4) Nozzle Range Branch.
UNDERSTANDING; EQUIVALENT
PIPING,
Piping limitations in this chapter are given in both linear
and equivalent lengths.
Linear piping is the actual length of straight pipe used on
either the main supply line or a branch.
Equivalent piping is equal to the total linear pipe used on
either the main supply line or a branch plus the equivalent
length of any fittings used on either the main supply line
or a branch. See Figure 3-15.
Equivalent Piping = (Linear Piping) +
Total Equivalent Length of Fittings Used)
All pipe fittings develop a pressure loss which can be
equated to the loss through a specific length of straight
pipe. This loss is the equivalent length of the fitting. See
Table 3-1.

CHAPTER IV
System Installation
GENERAL
This chapter will detail the basic information necessary for
proper installation of the Pyro Chem Restaurant Fire
Suppression System. However, before attempting any
installation it is necessary to attend a Factory Certification
Training Class and become Certified to install the Pyro Chem
Restaurant Fire Suppression System. Because it is impossible
to completely understand every aspect of an intricate pre-
engineered system simply by reading the Technical Manual,
Pyro Chem, Inc. will not be responsible for system installations
or maintenance performed by any non -Certified person(s).
Pipe and fittings for the discharge piping, conduit (EMT),
pipe straps, pipe hangers, mounting bolts, and other
miscellaneous equipment are not furnished as part of the
Pyro Chem Restaurant Fire Suppression System. These
items must be furnished by the installer.
Before attempting any installation, unpack the entire
system and check that all necessary parts are on hand.
Inspect parts for damage. Verify that cylinder pressure is
within the acceptable range as shown on the gauge.
CYLINDER INSTALLATION
The cylinder and valve assembly is shipped with an anti -
recoil plug in the valve discharge port.
CAUTION
The anti -recoil plug must remain in the valve discharge
port until the discharge piping is connected to the valve.
The cylinder must be mounted vertically with the
discharge port facing either left or right. The Models PCL-240
1 1MI.1 I1111111W
ED
and PCL-350 cylinders must be mounted using a Model MB-
15 Mounting Bracket Kit. The Model PCL-550 cylinder must
be mounted using a Model MB-1 Mounting Bracket Kit.
The bracket must be securely anchored to the wall using
bolts or lag screws. The wall to which the bracket is
attached must be sufficiently strong to support the cylinder.
The bracket should never'be fastened to dry wall or similar
material. If this type of wall is encountered, studs must be
located and the bracket fastened to them. See Figure 4-1.

2. Multiple Cylinder Installations.
A. Multiple Cylinder Actuation Using MCH/ECH Control
Head.
The Model MCH/ECH Control Head can be used to
pneumatically actuate a maximum of three (3) agent
cylinders. When a control head is used for multiple
cylinder actuation, it cannot be mounted directly onto a
cylinder valve. The control head must be installed
remotely using a Model MB-P2 Control Head Mounting
Bracket. The bracket must be anchored to the wall using
bolts or lag screws.
In order to actuate the agent cylinder(s) from a control
head, a '/4" NPT x 45' '/," flare type fitting (conforming to
SAE J513c) must be screwed into the base of the control
head actuator. Pneumatic tubing is then used to connect
the control head to the valve cap assembly of each agent
cylinder valve. See Figure 4-3.
NOTE
Pneumatic tubing used for remote cylinder actuation
shall have an outside diameter of/4" with a minimum
wall thickness of/,,". This is commonly known as
refrigeration -type copper tubing. All tubing fittings
shall be of the '/4", 45' flare type conforming to SAE
J513c. Compression type fittings are not acceptable.

FUSIBLE LINK DETECTOR
INSTALLATION
Fusible links are always used in conjunction with the
Model MCH Mechanical Control Head. After mounting the
cylinder and control head, the fusible link line can be
installed. The first step to installing the fusible link line is
to install the detector bracket(s). These brackets must be
installed in the plenum area of the ventilation hood over
all protected appliances and in each duct. See Chapter III
for detector placement guidelines.
Note: Only ML-style Fusible Links can be used.
Connect the fusible link brackets together using '/,"
conduit and the conduit connectors supplied in the
detector kit (Model FLK-1/1A). A Pyro Chem corner pulley
must be used whenever a change in conduit direction is
necessary. The conduit is connected to the control head
through a knockout in the upper left -side corner.
In general, fusible links centered in the detector brackets
are connected in series using %," or'/,," diameter
stainless steel cable. The spring plate in the control head
maintains tension on this series of fusible links. If the
tension is released for any reason (i.e., a fusible link
separates), the control head will operate and actuate the
system. Maximum limitations for the fusible link detection
line are as follows:
LINK DETECTOR
BRACKET
TERMINAL LINK
Fusible Link Line Limitations
Maximum # of detectors: 15
Maximum length of cable: 100 feet
Maximum # of pulleys: 20
Fusible links can be installed with or without fusible link
hangers (see Chapter II for description).
1. Fusible Link Installation Without
Hangers.
Begin installing links at the terminal bracket. The link is
connected to the far side of the terminal bracket using an
S" hook. The "S" hook must be crimped closed after the
link is installed. A tight loop is then made in the cable and
secured by the crimp provided. This loop is connected to
the other side of the terminal link (see Figure 4-6) and the
cable fed through the conduit to the next bracket.
The cable proceeding from the terminal link will be used
to connect the series links (see Figure 4-7). Series links
must be centered in their detector brackets.
After the last link in the series is connected, the cable
should be fed through the conduit back to the control
head. Thread the cable through the hole in the fusible link

Note: Only ML-style Fusible Links can be used.
NOTE
Crimps must always be used in conjunction with two
2) cable lengths. Loops are the accepted method of
connecting the cable to mechanical components. The
crimp must never be used on a single cable.
The fusible link line can now be put into a set position by
applying tension to the fusible link line. This is accom-
plished by using a'/," socket on the fusible link line
ratchet wheel. The ratchet wheel will be ratcheted in a
clockwise direction until the spring plate makes contact
with the top of the control head box. The fusible link line
is now in a set position. See Figure 4-8.

2. Fusible Link Installation Using Model
FLH-1 Fusible Link Hangers.
Beginning at the control head, feed the stainless steel
cable through the conduit and brackets to the terminal
bracket in one continuous length. Allow approximately
two and one-half (2.5) inches of slack at each bracket for
the installation of the Fusible Link Hangers. At the
terminal link, a tight loop is made in the cable and
secured by the crimp provided. The cable is attached to
the far side of the terminal bracket using an "S" hook. The
S" hook must be crimped closed after the cable is
installed. See Figure 4-9.

off caps are provided for each nozzle. These will prevent
dirt and grease from clogging the nozzle.
SYSTEM CHECKOUT AFTER
INSTALLATION
1. Model MCH Mechanical Control Head.
Before putting the system into service, all components
must be checked for proper operation. During this
checkout, assure that the carbon dioxide pilot cartridge is
not installed in the control head actuator. Remove the pull
pin from the hole in the slide plate.
To check satisfactory operation of the control head, cut the
terminal link or the "S" hook holding the link. This will
relieve all tension on the fusible link line and operate the
control head. The slide plate will have moved fully to the
right. The gas valve cable will have been released,
causing the gas valve to close. Any auxiliary equipment
connected to the dry contacts of the solenoid monitor
and/or the Miniature Switch in the control head will have
operated.
If any of these events fail to occur, the problem must be
investigated and repaired.
Repair the terminal link and put the fusible link line back
into the set position. This is accomplished by using a'/,"
socket on the fusible link line ratchet wheel. The ratchet
wheel will be ratcheted in a clockwise direction until the
spring plate makes contact with the top of the control
head box.
Once the fusible link line is set, the control head can be
placed in the set position. To set the control head, the
slide plate is moved from right to left, ensuring the bolt
extending from the cam arm is in the slot provided in the
slide plate. Continue moving the slide plate to the left until
the latching arm is in the locked position.
Once the control head is set, pull the pull handle on the
remote pull station to assure that the control head
operates. If the control head operates normally, the control
head can be reset as described above. Insert the pull pin
into the hole in the slide plate above the latching arm.
Replace the pull station handle, pull pin, and nylon tie.
Assure that the gas valve is fully open by ratcheting the
gas valve ratchet wheel.
CAUTION
Before screwing the carbon dioxide pilot cartridge
into the actuator, ensure that the actuator has a
Teflon O-ring installed.
Using a felt -tipped marker, write the date of installation in
the gray area of the carbon dioxide pilot cartridge. Screw
the cartridge into the control head actuator until hand -
tight. Never use pliers to tighten the cartridge into the
actuator.
Remove the pull pin from the hole in the slide plate and
install the control head cover. Insert the pull pin through
the local manual control handle and into the bushing.
Secure the pull pin with the nylon tie provided.
2. Model ECH-24/120 Electrical Control
Head.
Before putting the system into service, all components
must be checked for proper operation. During this
checkout, assure that the carbon dioxide pilot cartridge is
not installed in the control head actuator. Remove the pull
pin from the hole in the slide plate.
To check satisfactory operation of the control head, apply
heat to the last thermal detector in series. This will
operate the control head. The slide plate will have moved
fully to the right. The gas valve cable will have been
released, causing the gas valve to close. The indicator
light on the solenoid monitor will go out. Any auxiliary
equipment connected to the dry contacts of the solenoid
monitor and/or the Miniature Switch in the control head
will have operated.
If any of these events fail to occur, the problem must be
investigated and repaired.
Once the thermal detector has cooled, the control head
can be placed in the set position. To set the control head,
the slide plate is moved from right to left, ensuring the
bolt extending from the cam arm is in the slot provided in
the slide plate. Continue moving the slide plate to the left
until the latching arm is in the locked position.
Once the control head is set, pull the pull handle on the
remote pull station to assure that the control head
operates. If the control head operates normally, the control
head can be reset as described above. Insert the pull pin
into the hole in the slide plate above the latching arm.

CHAPTER V
System Maintenance
GENERAL
This chapter will detail the basic information necessary for
proper maintenance of the Pyro Chem Restaurant Fire
Suppression System. However, before attempting any
system maintenance, it is necessary to attend a Factory
Certification Training Class and become Certified to install
and maintain the Pyro Chem Restaurant Fire Suppression
System. Because it is impossible to completely
understand every aspect of an intricate pre-engineered
system simply by reading the Technical Manual, Pyro
Chem, Inc. will not be responsible for system maintenance
performed by any non -Certified person(s).
MAINTENANCE AFTER SYSTEM
DISCHARGE
1. System Cleanup.
The hazard area cleanup after a system discharge is very
basic. The chemical agent reacts with grease to form a
foam which can be easily cleaned up with hot, soapy
water. Agent that has not combined with grease can also
be cleaned up with hot, soapy water. The extinguishing
agent is non -toxic; however, its alkaline nature will cause
food to become inedible.
CAUTION
No cleanup should be attempted until the hazard area
is cool. Water should never be used to clean hot
grease.
Due to the alkaline nature of the extinguishing agent, it
should not be allowed to remain on kitchen surfaces for
an extended period of time. Although it will have a
minimal effect on stainless steel, it could cause
deterioration of non-ferrous metals like copper or
aluminum.
CAUTION
The extinguishing agent is electrically conductive. All
electrical equipment must be completely de -energized
prior to cleanup to avoid electric shock.
2. System Recharge.
After discharge, inspect the entire system for mechanical
damage. If the cylinder has sustained any mechanical
damage, it must be hydrostatically tested before refilling.
Disconnect the control head or pneumatic tubing from the
valve cap assembly.
Relieve the pressure from the top chamber of the cylinder
valve by depressing the core of the schrader valve in the
valve cap assembly. By performing this operation, the
valve will close and return to working status.
Verify that the cylinder has fully discharged by depressing
the valve stem. This will expel any residual pressure in
the cylinder. If the cylinder has residual pressure that
cannot be relieved by depressing the valve stem, use the
following procedure:
WARNING
Rubber gloves and goggles must be worn during this
procedure.
1. Place the anti -recoil plug in the cylinder discharge port
2. Remove the cylinder from the system and bring it
outside. Once outside, the cylinder must be fastened to a
secure object.
3. Slowly remove the valve by turning it in a counter-
clockwise direction.
4. When the valve has been unscrewed approximately
half -way, the pressure will bleed out through the pressure
relief slot in the valve threads.
Remove the valve and siphon tube. After system
discharge, the valve assembly must be carefully inspected
to ensure no mechanical damage has occurred. If
rebuilding is necessary, the Wet Valve Seal Rebuilding Kit
P/N 490-420698) should be used. It includes all system
components necessary to properly rebuild the valve (see
Chapter II for description).
Discard any remaining extinguishing agent in tank and
refill the cylinder with wet chemical extinguishing agent.
This agent is available in three size containers: 2.4 gallon
Model RL-240), 2.75 gallon (Model RL-275), and 3.5 gallon
Model RL-350). The RL-240 and RL-350 provide one
complete tank charge for the PCL-240 and PCL-350
respectively. The PCL-550 requires two (2) RL-275 charges.
NOTE
The pressure gauge attached to the extinguishing
system should not be used to determine when the
charging pressure has been reached. A pressure
regulator should be used.
Install the valve assembly and siphon tube in the cylinder
hand tight. Using the Pyro Chem Recharge Adapter Kit
P/N 500-420735), the cylinder can be re -pressurized to 175
psig @ 70' F. Invert the cylinder after pressurizing to clear
any air trapped in the siphon tube. Using a soap solution,
check for leaks.
3. Piping and Nozzles.
All nozzles must be removed and disassembled. The
strainers and the nozzle orifices must be cleaned in warm
water. Reassemble the nozzles and replace the nozzle
caps.
ULEX 3830
November 1, 1994
Chapter 5-System Maintenance
Page 5-2
Rev.1
Piping should be flushed with warm water and blown out
with air or nitrogen.
After cleaning the piping, replace all nozzles in their
proper location.
4. System Reset.
All fusible links should be replaced. The fusible link line
can now be put into a set position by applying tension to
the fusible link line. This is accomplished by using a 3/,"
socket on the fusible link line ratchet wheel. The ratchet
wheel will be ratcheted in a clockwise direction until the
spring plate makes contact with the top of the control
head box. The fusible link line is now in a set position.
After setting the fusible link line, the system can be put
back into service by following the SYSTEM CHECKOUT
AFTER INSTALLATION Section of Chapter IV.
REGULAR SYSTEM MAINTENANCE
1. "Six (6) Month Maintenance.
1. Check that the hazard has not changed.
2. Check that all nylon ties are in place and the system has
not been tampered with.
3. Check the entire system for mechanical damage.
NOTE
Before continuing, remove the cover from the control
head and insert the pull pin in the hole in the slide
plate above the latching arm. This will secure the
system, preventing accidental discharge. '
4. Disconnect the control head or pneumatic tubing from
the valve cap assembly of each agent cylinder. Remove
the carbon dioxide pilot cartridge and exercise the control
head to ensure it is functioning properly. Make sure the
gas shut-off valve and the remote pull station are
functioning properly.
5. Inspect fusible link detectors for excessive grease
buildup. Clean or replace links if necessary.
6. Reinstall the carbon dioxide pilot cartridge and replace
the control head cover and nylon tie.
7. Inspect the cylinder pressure, tap the gauge lightly to
ensure the needle is moving freely.
2. Annual Maintenance.
1. Inspect as per six (6) month maintenance instructions.
2. Disconnect and remove the discharge, piping from the
system. Using air or nitrogen, blow out the discharge
piping. Replace all nozzle caps.
3. Remove the cylinder to verify fill weight
4. Replace the carbon dioxide pilot cartridge
5. Fixed temperature sensing elements of the fusible alloy
type shall be replaced at least annually or more
frequently, if necessary, to assure proper operation of the
system.
3. Hydrostatic Testing.
The wet chemical agent cylinder(s) and pneumatic
cylinder(s) shall be hydrostatically tested at least every
twelve (12) years as per NFPA-17A.
