TACTICAL WATER PURIFICATION SYSTEM (TWPS)

PREPARATION FOR USE AND INSTALLATION INSTRUCTIONS

SET-UP OPERATION UNDER USUAL CONDITIONS

NOTE

When installing Adaptor A-01 the bolt on the check valve must be oriented in a

vertical position. Failure to observe this note may limit the effectiveness of the

check valve and result in an inability to maintain prime.

The support strap on Adaptor A-01 must be oriented near the top of the adaptor

and firmly secured to the pump frame to make sure air does not leak into the

adaptor. Failure to observe this note may result in a reduced pumping capacity or

an inability to maintain prime.

Attach Adaptor A-01 to the suction inlet of the raw water pump. Loop the strap over the

pump frame crossbar and tighten to a slight tension.

Attach Adaptor A-02 to the discharge outlet of the raw water pump.

Connect the priming vent hose to Adaptor A-02.

Connect, as needed to reach the MF Feed Tank, one or two 2 in. x 50 ft., green-banded

discharge hoses to Adaptor A-02 at the discharge outlet of the raw water pump.

Connect Adaptor A-05 to the end of the discharge hose that is coming from Adaptor A-

02.

Connect the 2 in. x 10 ft., green-banded suction hose to Adaptor A-05.

WARNING

Electrical hazard. The TWPS operates on 416 Volts AC.

Making electrical

connections to the TWPS power distribution panel must be coordinated with the

procedures for establishing electrical power to the TWPS. If Motor-Driven Pump P-

2 is used, do NOT connect its electrical power cable at this time. Failure to

observe this warning may result in serious injury or death from electrocution.

SODIUM BISULFITE SYSTEM SET-UP

CAUTION

Potential for damage to the MF elements and RO membranes. Chlorine will

destroy the MF elements and RO membranes. If the raw water source is

chlorinated, sodium bisulfite must be mixed into the raw water before it is pumped

into the MF feed tank. Sodium bisulfite neutralizes the chlorine. Failure to observe

this caution will result in the destruction of the MF elements and RO membranes.

The sodium bisulfite system MUST be set up before chlorinated raw water is pumped into the MF Feed

Tank. The instructions for setting up the sodium bisulfite system are described in WP 0010, Other Set-

Ups Operation Under Unusual Conditions.
