This manual is designed as a guide to service personnel in the
performance of operation, after use, inspection, maintenance, service
and recharge of Kidde dry chemical hand portable fire extinguishers.
These instructions are written and intended to be used by those
personnel already familiar with standard industry fire extinguisher safety
procedures and practices. All fire extinguishers should be installed,
inspected and maintained in accordance with the National Fire Protection
Association Standard titled “Portable Fire Extinguishers” (NFPA-10) and
all the requirements of the local authority having jurisdiction.
The instructions appearing in the National Fire Protection Association
standard for portable fire extinguishers (NFPA-10), the Code of Federal
Regulations, and in the Compressed Gas Association (CGA) pamphlets are
not generally repeated in this manual, except where they may emphasize
or clarify a point. Hydrostatic testing of fire extinguisher cylinders for
example is amply covered in NFPA-10 and CFR-49 part 180.209, which
reference procedures in CGA pamphlets C-1, C-2 and C-6.

These Kidde extinguisher models are stored pressure hardware designs,
which utilize steel and Aluminum agent cylinders. These models are
charged with various types of Kidde dry chemical agents that include
Regular (Sodium Bicarbonate), Purple-K (Potassium Bicarbonate) and
Multipurpose (Mono-Ammonium Phosphate). The extinguishers should
only be pressurized with nitrogen.
Never attempt to recharge a Kidde dry chemical fire extinguisher with
any other dry chemical agent other than that specified on the original
nameplate.
Descriptions
The Kidde dry chemical extinguishers are “stored pressure” hardware
designs that contain both the agent and expellant charge within the
same cylinder. The extinguishers are engineered to effectively discharge
the contents of the dry chemical charge.
These extinguishers consist of the following basic parts:
1. Agent cylinder - contains the dry chemical agent and expellant
charge.
3
2. Discharge valve assembly - consists of the operating lever, carrying
handle, valve stem, pressure gauge and discharge outlet that
permits the actuation and discharge of the dry chemical extinguishing
agent.
3. Siphon tube assembly - houses the spring assembly and provides
the means for the extinguishing agent to be drawn up from the
bottom of the cylinder to the discharge valve.
4. Ring pin and tamper seals - provide a means of visual assurance
that the extinguisher has not been activated, charged or subjected to
tampering.
5. Discharge hose assembly -provides a flexible means of agent
delivery from the discharge valve to the nozzle.
6. Nozzle assembly - provides the agent discharge stream shaping
characteristics necessary for optimum fire fighting performance.
Operation Instructions
1. Remove the extinguisher from its hanger or bracket.
2. Pull and remove the ring pin, breaking the visual tamper seal.
3. Using the extinguisher carrying handle, transport the unit to a safe
position upwind of the fire.
4. Remove the hose nozzle from the retention clip (if equipped) and,
while keeping the extinguisher in a vertical position, aim the nozzle
at the base of the fire.
5. Approach fire from upwind, to within approximately 8 to 12 feet of
the front edge of the fire.
WARNING:
Failure to start back at a sufficient distance from the front edge
of the fire or to use an adequate sweeping tempo of the agent
discharge stream could cause splashing and or scattering of the
burning material.
6. Starting back from this distance, squeeze the operating lever fully to
initiate the agent discharge.
7 Apply the dry chemical agent discharge in a side to side sweeping
manner, being careful not to splash or scatter the fuel. Operators may
advance closer as control of the fire is gained however, they should
avoid stepping into the fuel or fire area.
8. After fire extinguishment, stand by and be prepared to address any
re-flash.
9. Once the fire is out and has cooled, ensure the fuel is properly
removed and disposed of in accordance with any local handling
requirements.
4
After Use Instructions
Note: Fire extinguishers should always be recharged immediately
after any use
1. Invert extinguisher, then while securing and pointing the nozzle in a
safe direction, squeeze the operating lever valve to clear hose and
vent all remaining pressure from the extinguisher.
2. Notify proper person that extinguisher was used, so that the
extinguisher can be immediately recharged or a replacement
obtained.
Monthly Inspection Procedures
According to NFPA-10, inspection is a quick check that an extinguisher
is available and will operate. It is intended to give reasonable assurance
that the extinguisher is fully charged and operable. This is done by
verifying that it is in its designated place, that it has not been actuated or
subjected to tampering, and that there is no obvious physical damage or
condition to prevent its operation.
Inspections should be conducted whenever extinguishers are initially
placed into service and there- after at approximately 30 day intervals.
When circumstances require, more frequent intervals may be necessary.
Any time an inspection reveals a discrepancy, maintenance and service
procedures should be performed.
1. Ensure the extinguisher is properly located in plain view and its access
is unobstructed.
2. Examine unit for any signs of corrosion, leakage or physical damage.
3. Ensure the nameplate is secure and legible and that the “operating
instructions” face outward.
4. Ensure ring pin and visual inspection tamper seal are in place and
intact.
5. Ensure pressure gauge pointer needle indicates within the green
operable pressure range.
6. Heft or weigh extinguisher to determine its fullness.
Note: Kidde recommends stored pressure dry chemical fire
extinguishers be weighed at least semi-annually to verify the
proper agent charge weight in accordance with nameplate
instructions.
7. Visually examine the discharge nozzle, and/or hose assembly to ensure
it is clear and unobstructed.
8. Date and initial the inspection tag or record in accordance with NFPA-
10 and local requirements.
5
Annual Maintenance & Service Procedures
Per NFPA-10, maintenance is a thorough examination of a fire
extinguisher and is intended to provide maximum assurance that it will
operate effectively and safely. It includes a thorough examination of all
components and the repair or replacement of such items if necessary.
Maintenance should be performed at intervals not to exceed one year
apart or any time an inspection discrepancy dictates.
Kidde recommends that only authorized Kidde distributors or personnel
having been properly trained to recognize and correct discrepancies, as
well as understand all the proper industry safety procedures, conduct
the maintenance or service of Kidde fire extinguishers. Refer to the
trouble shooting section of this manual for additional information on
specific equipment observations or discrepancies. Only Kidde factory
replacement parts are recommended for use in Kidde extinguishers.
WARNING:
To prevent injury or death, always ensure all pressure is properly
relieved from an extinguisher prior to attempting any service,
repair or recharge.
1. Ensure extinguisher is installed in its proper location and that it is
readily accessible. Most Kidde dry chemical extinguisher models are
approved for temperature ranges between -40° F to +120° F.
2. Remove extinguisher from its hanger or bracket and ensure that all
mounting hardware is properly installed, secure and in good
operating condition.
3. Externally examine unit for any signs of damage that might prohibit
service or dictate the need for any special maintenance/repair
procedures.
4. The periodic re-hydrostatic test date of the extinguisher should be
checked. The maximum periodic interval for Kidde dry chemical
stored pressure hand portable fire extinguishers is 12 years.
Note: NFPA-10 requires stored pressure dry chemical fire
extinguishers having a 12 year periodic hydrostatic test interval
to be emptied and internally examined every 6 years. Should
this 6 year tear down requirement be due, refer to the recharge
section of this manual for recommended procedures.
5. Unthread and remove the discharge nozzle, and/or hose assembly
from the cylinder valve assembly and visually ensure it is not plugged
or obstructed. Closely examine the discharge nozzle, and/or hose
assembly (including hose crimp couplings) for any damage, wear or
conditions which might effect their proper function. Verify that the
6
discharge nozzle, and/or hose assembly is correct for the model.
(Newer Kidde models indicate this information on their nameplates)
6. Visually examine the cylinder valve discharge port for any signs of
thread wear, corrosion, obstructions or accumulations of any foreign
material.
7. Examine the pressure gauge for the following, properly depressurize
and replace if necessary. (For corrective action refer to the trouble
shooting section in this manual.)
(a) Ensure the gauge pressure needle indicates within the green
operable area.
(b)Visually ensure there is no external gauge damage, deformation,
dents or cracks.
(c) Verify gauge charge pressure properly correlates with charge
pressure on nameplate.
(d) Ensure gauge indicates proper compatibility for dry chemical
extinguishing agent.
(e) Ensure gauge indicates proper compatibility for use with either
aluminum or plated brass valve material.
Note: Recent Kidde Pro extinguisher models feature plated brass
valve body assemblies.
8. Closely examine the carrying handle and operating lever for any
damage or deformation, and ensure the rivets are secure.
9. Being careful not to accidentally discharge the extinguisher, pull
and remove the ring pin breaking the visual inspection seal, to ensure
the ring pin functions freely and is not bent, damaged or corroded.
Re-install proper ring pin through the proper lever and valve ports,
then install a new visual inspection tamper seal through the pull pin
loop and around the carrying handle.
10.Looking under the operating lever ensure the visual portion of the
valve stem shaft is not bent, damaged or corroded. (The top of the
stem should extend from the valve body approximately 1/4 of an inch.)
11.Ensure the extinguisher nameplate is legible and secure. The
nameplate operating instructions should face outward and be
orientated within 30 degrees of the pressure gauge face. Check to
ensure HMIS information is present and legible.
12.Reinstall and secure the discharge nozzle, and/or hose assembly into
the discharge valves outlet port. Adjust and secure the hose nozzle
into the retention band clip (if equipped).
13.Examine the cylinder hose retention band assembly (if equipped) for
any damage and ensure it is properly adjusted to accommodate the
hose assembly nozzle.
14.Weigh the extinguisher and verify that the total charged extinguisher
weight falls within the tolerance limitations specified on the
nameplate instructions.
7
15.Wipe the extinguisher clean with a damp cloth to remove any surface
dirt or contaminants that may have accumulated.
16.Upon satisfactory completion of the maintenance examination,
properly tag, label and record the procedure in accordance with
NFPA-10 and any local requirements.
Recharge Instructions
According to NFPA-10, recharge is the replacement of extinguishing
agent and expellant. All rechargeable fire extinguishers shall be
recharged after any use or as indicated by an inspection or when
performing maintenance. When performing extinguisher recharge, the
recommendations of the manufacturer shall be followed.
Because of potential performance or detrimental material compatibility
problems which may occur with the use of other agents, Kidde requires
that only the dry chemical extinguishing agent specified on the
extinguisher nameplate be utilized for recharge.
WARNING:
Prior to recharging an extinguisher, personnel should be
thoroughly familiar with the contents of this manual to
recognize any equipment conditions or discrepancies that might
prohibit the recharge of the extinguisher or direct further
equipment maintenance or repair.
1. Invert the extinguisher, then while securing and pointing the nozzle
in a safe direction, squeeze the operating valve lever to remove all
remaining pressure from the extinguisher. Check the extinguisher
gauge pressure reading to verify all pressure is removed.
WARNING:
To avoid personal injury or death, always ensure all pressure is
properly relieved from an extinguisher prior to attempting any
service, repair or recharge.
2. Visually examine overall extinguisher for any signs of damage, wear,
corrosion or other conditions which might prohibit the unit from
being recharged.
3. Unscrew and remove the discharge nozzle, and/or hose assembly from
the valve assembly.
4. Slowly unscrew the discharge valve assembly from the agent cylinder.
WARNING:
To avoid personal injury or death, should any audible pressure
leakage be observed during extinguisher disassembly,
technicians should stop any further service action and wait until
all residual pressure is relieved.
8
5. Remove the discharge valve assembly from the agent cylinder.
Disassemble the siphon tube and remove the spring and discharge
valve stem.
Note: Fire extinguisher valve assemblies are not typically
indexed for orientation with other cylinders, so any time
extinguisher valve assemblies are removed, they should always
be tagged or referenced so they remain matched to the specific
cylinder that they were removed from.
6. Closely examine all components to ensure they are not damaged,
cracked or worn. Remove the O-ring and replace. Re-lubricate o-ring
with a light coat of silicone grease such as Vislox-V711 or equivalent.
7. Examine the valve stem to ensure it is not bent or corroded. Replace
O-ring and re-lubricate with a light coat of silicone grease such as
Vislox-V711 or equivalent.
8. Properly reassemble the discharge valve assembly. Ensure the valve
stem, spring and siphon tube are correctly installed and securely
tightened.
9. Empty the agent cylinder and visually examine it internally
and externally for any damage, thread wear, dents, repairs, corrosion,
discoloration or contaminants. If necessary remove extinguisher
from service and replace.
10.Add the proper type and quantity of Kidde dry chemical agent
specified on the extinguisher nameplate recharge instructions.
11.Reinstall the discharge valve assembly onto the agent cylinder. Ensure
the valve is properly snugged down and the pressure gauge is
properly orientated perpendicular to the front of the extinguisher.
WARNING:
Regulated extinguisher pressurization sources should never
be set any higher than 25 PSI (172 kpa) over the intended
extinguisher charge pressure or be left connected to an
extinguisher for extended periods of time. Never stand directly in
front of an extinguisher gauge or stand over the valve assembly
during pressurization.
12.Install the proper Kidde pressurization charge adapter into the
discharge valve outlet port. Using a regulated source of dry nitrogen
containing a calibrated pressure gauge, depress operating lever
and slowly pressurize the extinguisher to pressure indicated on the
nameplate. Reference the calibrated pressurization gauge for proper
charge.
Note: To avoid damaging non-metal siphon tube assemblies,
charge pressure should be applied slowly.
9
Note: During recharge, dry chemical agent can accumulate
and pack within the siphon tube when installing the valve
assembly into the cylinder. Recharge personnel should ensure
the time required for total pressurization is appropriate for the
model size. Extinguisher pressurization obtained too quickly
may indicate a plugged siphon tube.
13.Upon reaching proper pressurization, release the operating lever,
shut off and remove the pressure source, then install the ring pin
into the valve assembly. Verify that the extinguisher gauge operating
pressure is also properly reading within the green operable area and
then install a visual inspection tamper seal through the ring
pin pull loop and around the top operating lever. Remove the
pressurization charge adapter from the extinguisher valve assembly.
14.Using a soapy solution or leak detecting fluid, properly perform a
leak check of the valve assembly, gauge and cylinder collar to ensure
no pressure leakage is occurring. Upon successful completion of the
leak check, properly clean and dry all extinguisher surfaces.
Note: Prior to placing recharged dry chemical extinguishers back
into fire protection service, Kidde recommends the extinguisher
pressure gauge reading be re-verified a minimum of 24
hours after pressurization.
15.Examine the discharge nozzle, and/or hose assembly to be sure it
is not loose, damaged, worn or obstructed. Reinstall and secure the
nozzle and/or hose assembly into the discharge valves outlet
port. Adjust and secure the hose nozzle into the retention band clip if
equipped.
16.Weigh the extinguisher to verify the total charged extinguisher
weight falls within the tolerance.
17.Wipe the extinguisher clean with a damp cloth to remove any surface
dirt or contaminates that may have accumulated.
18.Properly tag, label and record the extinguisher recharge procedure in
accordance with NFPA-10 and all local requirements.
Hydrostatic Test Requirements
Hydrostatic testing is the integrity pressure testing method of a
vessel utilizing a liquid compression medium. Kidde dry chemical fire
extinguisher cylinders require hydrostatic testing at periodic intervals
or any time the integrity of the vessel is questioned from any visually
observed condition.
Hydrostatic testing should be performed in accordance with NFPA-10
recommendations.
10
Evidence of conditions such as exposure to fire or heat, thread damage,
thread wear, corrosion, cylinder repairs or physical damage as detailed
within NFPA-10 require the extinguisher cylinder to be removed from
service and proper disposal at the owner’s direction.
Hydrostatic testing should only be performed by those persons trained
in the appropriate testing procedures/safeguards and having the proper
testing equipment, facilities and information.
Some Kidde hydrostatic test recommendations:
• Extinguisher cylinders should be replaced any time the pressure vessel
has been weakened due to corrosion, cuts, dents, digs, etc.
• That only water be used as the test medium and that the extinguisher
then be flushed clean, dried and visually re-examined after testing.
• The discharge valve assembly should be removed prior to hydrostatic
testing of the cylinder. (Refer to Note in Step 5 of Recharge
instructions.)
• The agent cylinder hydrostatic test marking method should only
utilize the proper type of record labels per NFPA-10 requirements.
• Never stamp or etch any markings onto the cylinder.
• Any time a fire extinguisher is known to have contained agents,
additives or mediums other than that specified on the nameplate, it
should be removed from service and properly disposed at the owner’s
direction.
• No repairs to the cylinder are permitted. If such cylinder repairs are
observed, the extinguisher should be removed from service and
properly disposed at the owner’s direction.
