OPERATION IN NUCLEAR, BIOLOGICAL OR CHEMICAL CONTAMINATED
AREAS - cont.
Setup Raw Water System. Refer to figure 2-78. Working from the ROWPU control panel to the water
source, connect components of the raw water system as follows:
To prevent contamination of product water system, do not use discharge hoses intended
for potable product water in the raw water system. Product water hoses are identified by
a blue stripe running the full length of the hose.
ROWPU should be positioned as close as possible to the water source.
Raw water pump No. 1 has a female coupling on the pump suction port and male on
the discharge port. Pump No. 2 has a female fitting on both suction and discharge
Use the minimum number of discharge hoses required between control panel and
raw water pump No. 2.
Connect discharge hoses between RAW WATER coupling on control panel and discharge
coupling of raw water pump No. 2.
Ensure all seals are in place and quick disconnect coupling are locked. Raw water pumps
will not prime if suction hoses draw air.
Use the minimum number of suction hoses required to reach the water source.
Connect three hard rubber suction hoses to suction coupling of raw water pump No. 2.
To prevent damage to the ROWPU, do not operate raw water pump without strainer.
Connect strainer to end of last suction hose.
Connect float to strainer with enough rope to allow strainer to go under water, but not touch
Place strainer and float in water source. Avoid placing strainer near sandy areas.
Connect raw water pump No. 2 electrical cable to RAW WATER PUMP NO. 2 receptacle on
Check security of all hose connections.
