TACTICAL WATER PURIFICATION SYSTEM (TWPS)
PREPARATION FOR USE AND INSTALLATION INSTRUCTIONS
COLD WEATHER SET-UP OPERATION UNDER UNUSUAL CONDITIONS
SET UP THE RAW WATER SYSTEM
NOTE
If site conditions allow, use only one pump and as few raw water hoses as
possible. When only one pump is required, motor-driven P-2 pump is highly
recommended. The cyclone separator is not used in cold weather conditions.
Two possible raw water system configuration cold weather set-ups are described here. They are:
- P-1 Pump to P-2 Pump Configuration Deployment.
- P-2 Pump Only Configuration Deployment.
NOTE
As the discharge hoses are laid out and connected, any excess length must be
taken up in long smooth curves to avoid kinking of the hose when pressurized.
P-1 PUMP TO P-2 PUMP CONFIGURATION DEPLOYMENT
CAUTION
Potential water damage. Make note of potential tidal or river flood conditions and
locate the raw water pumps to prevent the pumps and hose heating blankets from
becoming submerged. Failure to observe this caution may result in water damage
to the pump and diesel engine or motor.
1. Position the raw water pumps as follows (see Figure 12):
WARNING
Three person lift. Three people are required to safely lift Diesel-Driven Pump Skid
P-1. Lift with your legs, not your back. Failure to observe this warning may result
in back injury.
Two person lift. Two people are required to safely lift Motor-Driven Pump Skid P-2.
Lift with your legs, not your back. Failure to observe this warning may result in
back injury.
a. Place a marker where the raw water diesel engine-driven P-1 pump skid is to be placed.
Do not remove the diesel pump skid from the TWPS skid at this time. Keep it inside the
heated enclosure.
b. Place a pump insulating platform on the ground where the raw water Motor-Driven Pump
P-2 is to be located.
c. Move motor driven pump skid P-2 into place on top of the insulating platform.
