DUSTY AND SANDY AREAS.
a. Protect equipment. Leave side covers down except over control panel.
b. Keep ground around ROWPU damp to prevent loose, blowing sand and dirt.
c. Cover all water storage tanks and chemical pails.
2-23.
RAINY AND DAMP AREAS.
CAUTION
To avoid electrical shorts, keep electrical items dry.
a. Provide good water drainage.
b. Protect chemicals.
2-24.
SALTWATER AREAS.
a. When preparing for movement after saltwater operations, perform PREPARATION FOR MOVEMENT procedure
b. After backwash is completed, drain brine tank and set chemical feed control valves to PRIME. Place the product
water discharge hose into the brine water tank. Operate the ROWPU to produce nonchlorinated product water (minimum
1,000 gallons).
c. When the tank is full or the minimum requirement is met, shut down the ROWPU (paragraph 2-14).
d. Remove the raw water strainer and hose from the source and place it in the tank of NONCHLORINATED product
water.
e. Follow INITIAL ADJUSTMENTS AND CHECKS (paragraph 2-7) and OPERATING PROCEDURE (paragraph 2-
9), except for moving the chemical feed valves to RUN(NO CHEMICALS SHOULD BE INJECTED INTO THE SYSTEM
DURING THIS PROCEDURE), until the nonchlorinated tank is empty.
f. Shut down the ROWPU following SHUTDOWN PROCEDURES (paragraph 2-14).
This procedure should be used to flush the salt deposits and bacteria from the system and the RO elements. By flushing
this from the system, it slows corrosion and bacterial growth.
2-25.
NUCLEAR OR CHEMICAL CONTAMINATED AREAS:
a. The ROWPU has overpack items which are used as a post-treatment when nuclear or chemical contaminants
are present. The equipment consists of a cartridge to remove nuclear contaminants, a cartridge used to remove
chemical contaminants, and the adapters, bushing, clamps, couplings, reducers, and tubing needed for assembly.
WARNING
Radioactive contaminants are potentially hazardous. Use extreme care in replacing cartridge and
follow safe procedures in their handling and disposal.
