TROUBLESHOOTING GUIDE

WARNING: Before attempting to correct any leakage problem, be sure that the agent cylinder

and hose are completely depressurized. Check to determine the source of a leak

before the extinguisher is depressurized. Leakage repairs will require

depressurization and removal of the valve assembly. Depressurize by

discharging into a Closed Recovery System or inverting the extinguisher. After

depressurizing the extinguisher and correcting the problem, it will be necessary

to clean all valve parts thoroughly.
