CAUTION
Hot water is present in the heater and will drain when blender hose is disconnected.
4. Disconnect the blender hose (5) from the water heater (13) bottom connection and connect it to the blender pipe (6) on the
tank unit.
CAUTION
Insure that the water heater is cool before stowing the main electrical power cable and fuel and water hoses
in the storage compartment.
5. Disconnect the fuel hoses (14) from the water heater (13) and the pump unit (after the water heater has cooled) and stow in
the water heater storage compartment. Cap fuel supply and return lines. Restart pump unit or open VALVE NO. 1.
6. Blend 175 pounds of calcium hypochlorite (1/2 lb to 1 gal. of water) to the 350 gallons of water through the blender pipe
at a slow but steady rate. If the mixture is not used immediately, it must be stirred until used. Stir the mixture 3 minutes
before using.
7. If agitation is required, close VALVE NO. 1, disconnect the agitator-blender hose (5) from the blender pipe (6) and attach
it to the agitator-pipe (7) on the tank unit.
MIXING WATER AND LIQUID CHEMICALS USING THE PRIME DETERGENT TANK
Concentrated liquids which dissolve readily in water may be mixed with water in the pump cavity by using the prime-
detergent tank. The chemical to be mixed with water is placed in the prime-detergent tank after the pump unit has been
primed. It is metered into the pump cavity using VALVE NO. 4. The water and chemical mixture is then discharged through
the discharge hoses. Water should not be discharged to the tank unit during metering of liquid chemicals. The procedures
for using two of the more common concentrated liquids, liquid detergent (Page 0028 00-2, item 9) and fire extinguishing
foam forming liquid (Page 0028 00-2, item 13) for petroleum fires are given below.
