If a TWPS unit is to be taken out of service to use for training, the RO Elements should be removed and
replaced with RO Element Simulators. Install RO Element Simulators as follows:
WARNING
The TWPS must be in Shutdown and the TQG and TWPS main breaker must be off
(Army) or the TWPS disconnected from its power source (Marine Corps) prior to
removing or installing an RO element. Failure to observe this warning can result in
injury or death from electrocution or damage to equipment.
High pressure. The RO Vessels and RO system may be pressurized up to 1200
psig. The TWPS must be drained down to relieve RO system pressure prior to
working on any part of the system. Failure to observe this warning can result in an
explosive release of parts that can cause injury or death to personnel and damage
to equipment.
1. Make sure the TWPS is in Standby Shutdown with Drain-Down. Refer to WP 0017.
2. Refer to RO ELEMENT REPLACEMENT in this work package and perform the following steps:
a. Remove the piping from in front of the RO vessels.
b. Remove the end caps from the RO vessels.
c. Remove the RO elements from the RO vessels.
d. Clean and inspect the inside of the RO vessels.
3. Install an RO element simulator in each RO vessel as follows (see Figure 9):
NOTE
Each RO element simulator comes as an assembly. Steps 3a-3d are provided in
the event that components have been separated from an RO simulator assembly.
a. Make sure a permeate port adapter is inserted over the narrower end of both of the
pressure vessel adapters.
b. Lightly lubricate the o-rings on both of the pressure vessel adapters with glycerin or
comparable lubricant.
