1. Set up the cleaning waste storage tank if needed as follows (see Figure 1):
a. Set up the Waste Tank within 30 feet of the TWPS waste out connection. Face the
female tank connection toward the TWPS skid.
b. If the terrain allows, set the tank at an elevation so that the top of the full tank will be
below the bottom of the RO Feed Tank.
c. Connect an A-16 Adaptor to both connections on the waste tank. Close shut-off valve V-
706 on both of the A-16 adaptors.
d. Be sure that the zipper on the waste tank is zipped closed.

e. In combat deployment the waste may be discharged into a depression in the ground
located at an elevation below the TWPS.
2. Put citric acid in the cleaning waste tank for neutralizing the cleaning solution when the solution is
flushed into the tank as follows:
WARNING
Acid chemical. Wear a protective face shield, chemical gloves, and a chemical
apron when handling citric acid. Avoid inhaling chemical fumes. If acid spills,
immediately flush the area with water from the auxiliary hose. Failure to observe
this warning may result in mild irritation of the nose, throat, eyes, and skin.
a. Make sure a bucket of water is placed near the cleaning waste tank to rinse any area of
skin or clothing that comes in contact with citric acid.
b. Open the cleaning waste tank zipper.
c. Open an extra AC-210 Citric Acid bucket. Pour all of the contents into the cleaning waste
tank. If using a different source of citric acid, pour in 20 lbs of citric acid. (After all of the
cleaning waste has been discharged into the tank, the pH will be approximately 9).
d. Close the cleaning waste tank zipper.
