5 SYSTEM RECHARGE AND RESET
ose individuals responsible for maintenance of a Janus Fire Systems® fire extinguishing system utilizing
Novec 1230 fluid 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.
5.1 Piping and Nozzles
High heat from a fire could damage piping and nozzles, and possibly pipe support members. Check all
pipe supports and fittings 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.
5.2 Recharging
Recharge consists of removing the cylinder, reconditioning and cleaning the valve assembly, and refilling
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. All removable trim components shall be removed before
transportation.
Do not apply excessive force to the low-pressure supervisory switch or pressure gauge or attempt to carry
the cylinder assembly or valve assembly by the low-pressure switch or pressure gauge. The low-pressure
supervisory switch and pressure gauge are not designed or intended to be used to carry the cylinder or valve. If
the low-pressure supervisory switch or pressure gauge breaks at the tting, agent will discharge through the port
causing possible personal injury or property damage, and loss of agent.
5.2.1 Removing The Cylinder
• Remove the electric and pneumatic valve actuators and install the shipping cap onto the valve actuation
connection.
• Remove the empty cylinders by removing the discharge pipe and installing the anti-recoil safety plug or
device.
• Disconnect the low-pressure supervisory switch electrical connector.
• For Mv and Lv Series cylinders, remove the low-pressure supervisory switch and pressure gauge
assemblies from the cylinder valve.
Do not remove the pressure gauge or low-pressure supervisory switch from the Sv cylinder valve during the
recharge process.
