Amerex 05614 - Manual (Page 3)

2
OPERATION – After the fire has been successfully
extinguished and it has been determined that it is
completely out:
1.
Confirm that the nozzle lever is in the CLOSED
position.
2. Close the nitrogen valve (move "T" handle to
CLOSED position)
3. Remove ring pin and CLOSE agent cylinder valve
(Valve A in Fig. 1) to prevent further chemical from
entering the hose.
4. Remove ring pin and OPEN pressure vent valve
(Valve B in Fig. 1) to allow nitrogen gas to by-pass
the chemical and pressurize the hose.
5. Open discharge nozzle to vent all residual
chemical and nitrogen gas pressure.
6. Re-open nitrogen valve if additional pressure is
required.
7. When recharging this unit, reset agent cylinder
and vent valves, install ring pins and lockwire
seals.
CAUTION: USE OF DRY CHEMICAL AGENT EXTINGUISHERS ON FIRES ON DELICATE
ELECTRONIC
EQUIPMENT IS NOT RECOMMENDED. IT MAY
SUCCESSFULLY EXTINGUISH THE FIRE BUT MAY DAMAGE THE
EQUIPMENT BEYOND REPAIR. (Consult your Amerex Distributor for more
details.)
Discharge Time (approx.): 60 - 70 seconds
Effective Range of the
agent throw is: 30 - 40 feet
Hose Length: 50 feet
RECHARGE FIRE EXTINGUISHERS IMMEDIATELY AFTER ANY USE
SHUTDOWN
1. After making sure that the fire has been completely extinguished, close the nozzle valve and then close
the "T" handle nitrogen valve. Wheeled Extinguisher – Tip over until it rests on both wheels and handle
(in this position much of the remaining chemical will stay in the cylinder). Stationary Extinguisher – see
instructions below.
2. Open the nozzle valve slowly to clear the hose of any remaining pressure and chemical (be prepared for
recoil and discharge of agent).
WARNING: MAKE SURE THAT ALL PRESSSURE HAS ESCAPED BEFORE ANY FURTHER DISASSEMBLY.
3. Stand unit upright after complete depressurization.
NOTE: Nitrogen pressure in the agent cylinder cannot escape through a disconnected nitrogen hose
assembly due to a check valve in the system. Always be careful when removing the fill cap.
4. Coil the extinguisher hose onto the storage rack and position the nozzle onto the mount in preparation for
transport to the recharge location.
CAUTION: DO NOT TRANSPORT A NITROGEN CYLINDER WITH ANY REMAINING PRESSURE
WITHOUT INSTALLING THE PROTECTIVE SHIPPING CAP.
VENTING DEVICE
(Standard on all Stationary Extinguishers, Optional on Wheeled Extinguishers)
A venting device has been installed on all stationary extinguishers to provide a means of safely and easily
relieving residual nitrogen pressure from the agent cylinder while utilizing the same pressure to evacuate
or "blow down" the hose.
CAUTION: VALVE SHUT-OFF HANDLES MUST BE
IN THE POSITIONS SHOWN WHEN EXTINGUISHER
IS ON STANDBY OR IN ACTUAL OPERATION.
