TACTICAL WATER PURIFICATION SYSTEM (TWPS)
UNIT MAINTENANCE PROCEDURES
AIR SYSTEM, HIGH PRESSURE
11. Install the new air receiver tank as follows (see Figure 14).
a. Inspect the support band rubber cushions (19) and replace if damaged or worn.
b. Slide the new tank (21) into position under the supports bands (18).
c. Push the tank back until it just clears the RO Feed Pump inlet pipe.
d. Position the upper rubber cushions (19) between the tank and the support straps.
NOTE
Make sure that the air hose connector on the air tank shut off valve is horizontal to
the TWPS floor and facing toward the front of the TWPS.
e. Reinstall the bolts and washers (16 & 17) in the support straps and tighten to secure the
air receiver tank to the floor of the TWPS.
f. Connect the air hose to Air Tank Shut-Off Valve V-907 (15).
12. Reinstall the waste out pipe spool as follows (see Figure 14):
a. Position the waste out pipe spool (20) into its original location.
b. Reinstall but do not tighten the three flex strut pipe supports (14) that secure the waste
out pipe spool to the floor of the TWPS.
c. Slide one pipe coupling gasket retainer (8C), one gasket (8A), and the pipe joint (8C)
over the 3-in. vertical waste out pipe and slide them all the way down the pipe.
d. Slide the other gasket retainer and gasket onto the MF upper reject pipe spool.
e. Position the MF upper shell reject pipe spool in place as follows:
1) Install the flex strut pipe support (11) on the pipe support beam to the right of valve V-
401 and slide the pipe assembly (13) onto the flex strut pipe support.
2) Install the sanitary clamp (12) on the upper end of the MF Upper Shell Reject Pipe.
3) Complete the 3-in. pipe coupling (8) connection on the 3-in. vertical waste out pipe,
but do not tighten.
4) Connect the air tube to the actuator for valve V-401 (10).
f. Install the RO Feed Tank Drain Pipe assembly as follows:
1) Install the drain elbow and nipple (4) to the 3-in. waste out pipe spool.
2) Thread the drain pipe containing RO Feed Tank Drain Valve V-412 (3) into the drain
elbow.
3) Inspect the 2-in. rubber hose and hose clamps (2) removed earlier for wear, damage,
or corrosion. Replace if needed.
4) Lubricate the inside of the hose and the outside of the pipe sections with glycerin.
Slide the four hose clamps and the 2-in. rubber hose over the ends of the RO Feed
Tank Drain Pipe. Do not tighten the clamps.
g. Connect the two open ends of the RO reject pipe spool using the grooved coupling (9).
NOTE
Make sure that the valve actuator is installed with the air tube side facing in and
the valve actuator facing left.
h. Install MF Lower Shell Out Valve V-402 (6) and pipe elbow (7) in the waste out pipe spool
(21). Do not tighten.
i. Reconnect the air tube to the valve actuator for valve V-402 (6).
j. Inspect the sanitary clamps and gaskets (5) for wear or damage. Replace if needed.
k. Connect the two open ends of the MF lower shell waste out pipe spool using the sanitary
clamps and gaskets (5). Tighten the clamps. Tap the clamps all around to ensure that
they are properly aligned and tighten again.
