TACTICAL WATER PURIFICATION SYSTEM (TWPS)
PREPARATION FOR USE AND INSTALLATION INSTRUCTIONS
COLD WEATHER SET-UP OPERATION UNDER UNUSUAL CONDITIONS
2. Attach the ice intake strainer to a hose section.
3. Push the strainer and hose through the ice hole to a depth of 2 ft. from the bottom in shallow
water less than 20 ft. deep, or 20 ft. if deeper. This helps provide water that is above freezing.
4. Connect the number of 10 ft. long suction hoses to each other that will be required to connect the
ice intake strainer to Adaptor A-01 at the suction of the raw water pump. No more than two hoses
should be out of the water. If the ice is stable, the pump may be set out on the ice.
COMPLETING P-1 PUMP SETUP (IF IN USE) AND ESTABLISHING RAW WATER FLOW
Do not establish raw water flow until the distribution system has been set up and you are ready to
complete the startup. In cold weather operation, it is important to keep water moving to avoid freezing.
Procedures for establishing raw water flow are described in WP 0014, Initial Start-Up or Start-Up with the
System Fully Drained. If Diesel-Driven Raw Water Pump P-1 is to be used, it must first be warmed for at
least an hour inside of the TWPS to avoid freezing of the water when introduced into the pump. Above 0
degrees Fahrenheit, the diesel may be moved to it's location and started normally if it is started quickly
after moving from the heated TWPS. Below 0 degrees Fahrenheit, it will probably require use of the
electric start procedure as described in steps 1 and 2 below.
1. Ready the P-1 pump as follows:
CAUTION
When adding fuel to the tank, be careful not to push the screen filter into the tank.
a. With the fuel tank removed from the diesel-engine skid and setting outside of the TWPS,
add fuel as needed.
b. Take the 24-volt diesel engine starting cable out of the diesel generator battery storage
compartment (A-TWPS only).
c. Lay out, but DO NOT CONNECT the 24-volt diesel-engine starting cable from the diesel
generator 24-volt slave outlet to where the diesel engine-driven pump is to be placed.
d. Place the pump insulating platform on the ground near the diesel generator 24-volt slave
outlet.
WARNING
Three person lift. Three people are required to lift Diesel-Driven Raw Water Pump
P-1. Lift with your legs, not your back. Failure to observe this warning may result
in back injury.
e. Open the flap at one end of the top of the insulating cover and the hook and loop seam at
the other end and grab the frame in three places to lift the P-1 pump skid.
f. Move the P-1 pump off of the TWPS skid to the pump insulating platform.
