Amerex 05617 - Manual (Page 3)

the extinguisher is filled with the proper amount of chemical is to weigh the unit. The gross weight is
indicated on the nameplate (label).
Note: Slight pressure variances in the gauge reading may be found if the extinguisher has been subjected to
extremes of heat or cold. High temperatures can cause high gauge readings and low temperatures, low
readings. When in doubt, condition the extinguisher to 70°F (21°C) for several hours to obtain more
accurate pressure gauge readings.
8. Record the date the unit is being placed into service on the inspection tag and attach it to the extinguisher.
INSTALLATION
Do not place this extinguisher close to a potential fire hazard. Amerex recommends location no less than a 50 foot
distance from the hazard while leaving an unobstructed access. Avoid placing it in an extremely hot or cold place. The
operational temperature range for this extinguisher is -40° to +120° F (-40° to + 49° C). The extinguisher should be
adequately protected if temperatures outside of this range are anticipated. Keep the extinguisher clean and free from
dirt, ice, chemicals and any contaminants which may interfere with its proper operation. DO NOT FUNCTIONALLY
TEST THIS FIRE EXTINGUISHER. (Testing or any use may cause the extinguisher to gradually lose pressure and
become ineffective.)
OPERATION
CAUTION: Persons expected to use this extinguisher should be trained in initiating its operation and in the
proper fire fighting technique. “Hands on” training will prepare personnel with the feel for this high
pressure extinguisher so that the most effective application can be utilized in an emergency situa-
tion. The basic operating instructions are contained in the pictogram portion of every extinguisher
nameplate (label). The following elaborates on these instructions.
1. Move the extinguisher to within approximately 50 feet of the fire site.
KEEP EXTINGUISHER UPRIGHT.
CAUTION: THIS EXTINGUISHER MUST BE OPERATED IN AN UPRIGHT POSITION. IF
EQUIPPED WITH AN OPTIONAL TOW LOOP AND VEHICLE TOWED TO THE
FIRE SCENE, REMOVE FROM TOW HITCH AND OPERATE IN A VERTICAL
POSITION.
2. Twist and PULL RING PIN. Rotate (pull) valve lever toward the hose. With the nozzle
lever in the CLOSED position, PULL HOSE FROM RACK. START BACK 30 FEET
from the fire.
3. Grasp nozzle hand grip and AIM AT BASE OF FIRE nearest you.
4. OPEN HOSE NOZZLE by pulling the handle fully towards you (brace yourself, hold
the nozzle firmly and be prepared for a discharge recoil). SWEEP SIDE TO SIDE
across the base of the fire and past both edges. Progressively follow up until the
fire is extinguished. Work the fire away from you while being alert for flashbacks.
Move closer as the fire is extinguished but not so close as to scatter or splash the
burning material.
WARNING: THIS EXTINGUISHER OPERATES AT HIGH PRESSURE - BE PREPARED
FOR A HIGH VELOCITY DISCHARGE RECOIL.
5. When the fire is out, push the nozzle lever forward to the CLOSED position. Stand
by and watch for possible re-ignition.
