RECHARGE
RECHARGE
Before proceeding to recharge any extinguisher, visually
examine the unit for any physical damage or impairment
which may further dictate the need for maintenance.
NOTICE
Extinguishers out of service for maintenance
or recharge shall be replaced by spare extin-
guishers of the same type and at least equal
rating.
To return the extinguisher to service after use:
NOTICE
If dry chemical is found on cartridge, this
indicates a bad gas tube. For gas tube
replacement instructions, refer to Gas Tube
Replacement Procedures on page 23.
1. Invert the extinguisher and open nozzle to clear dry
chemical from hose and to relieve all pressure remaining
in shell.
2. Return the extinguisher to the upright position.
“E” Models (Metal cartridge guard) – Place the hose
behind the push lever and insert the nozzle in the holder.
“G” Models (Composite cartridge guard) – Do not
place hose in nozzle holder or behind push lever as hose
must be free to remove guard.
3. Remove the cartridge guard and spent cartridge.
“E” Models (Metal cartridge guard) – Pull guard straight
out.
“G” Models (Composite cartridge guard) – Pull guard
out from the top until clip disengages from the cartridge
and then lift up guard to allow the bottom fork to clear the
hose elbow.
To remove cartridge, turn in direction of arrow printed on
cartridge. Install a safety shipping cap (Part No. 77250)
for left-hand and Part No. 77251 for right-hand threaded
cartridges.
!
CAUTION
Do not install cartridge onto extinguisher at this time.
4. Remove fill cap slowly and deliberately. If there is any
residual pressure in the shell, it will be relieved through
pressure relief vent hole or grooves in fill cap while 31/2
threads are still engaged.
