c.
When the tank is full or the minimum requirement is met, shut down the ROWPU (para. 2-31).
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 (para. 2-23) and OPERATING PROCEDURE (para. 2-25),
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 (para. 2-31). This procedure should be
used to flush the salt deposits and bacteria from the system and the R.O. elements. By flushing this from the system, it
slows corrosion and bacterial growth.

NUCLEAR OR CHEMICAL CONTAMINATED AREAS
a.
The ROWPU has overpack items which are used as a posttreatment 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, bushings, clamps, couplings, reducers, and tubing needed for assembly.
WARNING
Radioactive contaminants are potentially hazardous. Use extreme care in replacing cartridges and follow
safe procedures in their handling and disposal.
NOTE
Do not operate chlorination feed pump during NBC operation.
b.
For nuclear, biological OR chemical contamination, use BOTH the cartridge marked "FOR USE WITH
RADIOACTIVE CONTAMINATED WATER ONLY" AND the cartridge marked "FOR USE WITH CHEMICALLY
CONTAMINATED WATER ONLY."
c.
Exchange the inlet and outlet raw water pump adapter which is used in the NBC system and prepare to
assemble NBC filters between two raw water tanks as shown in figure 2-80.
