SERVICE AND REPAIR
The best assurance against fire extinguisher malfunction is proper operation, recharge, inspection and maintenance. To
remedy any disorder detected through periodic inspection or maintenance examinations, the following table lists some
of the possible irregularities that may develop and gives suggestions for corrective action.
COMPONENT DISORDER CORRECTIVE ACTION
Suppressing Dents* or abrasions Hydrostatically test (see Hydrostatic Test Instructions ,
Agent Shell Form No. F-7602, latest revision) and refinish (clean damaged
area and repaint) or replace extinguisher.
Rust spots, pits and corrosion deposits Clean corroded areas, and repaint, replacing tank if there is any
corrosion penetration.
Threads nicked, cross-threaded, Clean threads with a stiff bristle brush. Small nicks or burrs
corroded or worn may be eliminated by careful re-tapping. If damaged or worn
extensively, the extinguisher should be replaced.
Fill opening gasket seating surface nicked, Clean seating surface and lubricate the surface lightly with a
gouged, corroded or bearing dirt deposits good grade of high heat resistant grease. If surface is sharply
nicked or deeply gouged, replace extinguisher.
Obstructed pressure vent hole in fill Clear vent hole with a stiff, unbreakable wire probe of lesser
opening threads diameter than vent hole.
Seam welds evidencing discoloration or Consult Johnson Controls,
pin holes Marinette, Wisconsin 54143-2542.
Fill Cap Abraded, cracked, corroded or otherwise Replace, destroying affected cap to prevent reuse.
damaged fill cap
Threads corroded, nicked, cross-threaded or Replace, destroying affected cap to prevent reuse.
worn
Cut, checked, deformed, stiff, brittle or Replace, lubricate new gasket lightly.
worn gasket or quad ring
Plastic indicator housing cap cracked or Replace plastic cap.
missing
Indicator stem immovable or stiff operating Disassemble and clean, replacing parts as required.
Suppressing Improper fill level Fill shell to rated capacity with ANSUL suppressing agent
Agent specified on nameplate.
**Caked dry chemical Discard agent and refill clean tank to rated capacity with ANSUL
suppressing agent specified on nameplate.
Gas Tube Bent, cracked, broken or obstructed Replace, using factory built and pressure tested assembly only.

Cut, loose, leaking, damaged, or missing check Replace, using factory built and pressure tested assembly only.
valve See page 23.
Nameplate Unreadable wording Use a mild abrasive (scouring powder) to clean plate. If
read ability cannot be improved, replace operating nameplate.
Loose Inspect area under plate.*** If corroded, see “Suppressing Agent
Shell – Rust spots, pits and corrosion deposits’’ and re-affix
nameplate using a good grade of heatless adhesive.
Missing Replace with correct nameplate.***
Expellant Gas Rust spots, pits and corrosion deposits Clean corroded areas and repaint or replace cartridge if there is
Cartridge any corrosion penetration.
Dents or abrasions De-pressurize, remove seal and destroy both internal and
external threads on the cartridge to render the vessel unusable.
Threads on cartridge nicked, cross- The cartridge should be replaced and properly scrapped.

** The term caked, as applied to dry chemical describes a specific condition that is best identified as dry chemical containing hard lumps. These lumps will render
a dry chemical extinguisher inoperative. The condition usually follows the absorption and later the evaporation of an unusual amount of moisture. It is often
confused with ‘‘packing’’ (a condition produced by normal settling, by vibration or impact.) A simple procedure to determine which condition exists is the UL test
in which lumps are dropped from 4 in. (102 mm) onto a clean hard surface. if the lumps do not break up into individual particles, caking is present. For additional
details, refer to ANSUL Technical Bulletin Caking Versus Packing of Dry Chemical Agents (Form No. F-8083, latest revision).
