7 SYSTEM RECHARGE AND RESET
ose individuals responsible for maintenance of a Janus Fire Systems® FM-200® clean agent re
extinguishing system must be trained.
To maintain FM Approval cylinder recharge must be done at a Janus Fire Systems® recognized facility.
is chapter does not include instructions on resetting the automatic control system. Refer to the appropriate
technical manual for this information.
7.1 Piping and Nozzles
High heat from a re could damage piping and nozzles, and possibly pipe support members. Check all pipe
supports and ttings for any signs of damage or corrosion. Remove nozzles from pipe and inspect for damage,
corrosion, or obstructions. Clean nozzles and reinstall making certain to tighten and aim properly.
7.2 Recharging
Recharge consists of removing the cylinder, reconditioning and cleaning the valve assembly, and relling
and pressurizing the cylinder.
Do not transport the cylinder unless the anti-recoil safety device is in place. Handle the cylinder assembly with
care even when the safety device is in place.
Do not apply excessive force to the low-pressure supervisory switch or attempt to carry the cylinder assembly
or valve assembly by the low-pressure switch. The low-pressure supervisory switch is not designed or intended
to be used to carry the cylinder or valve. If the low-pressure supervisory switch breaks at the tting agent will
discharge through the port causing possible personal injury or property damage.
