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.
