Maxiva ULX COFDM Series
2.11.3 Initial System Cleaning
Once the cooling system has been determined to be free of leaks it will have to be
cleaned and flushed before continuing the installation.
STEP 1
Create cleansing solution.
Using a mixture of distilled water (see
Appendix B) and a cleaning solution (a mixture of 2 cups of a trisodium
phosphate-based low sudsing detergent, such as Cascade, mixed in 2
gallons of water), proceed with the following steps.
NOTE:
The detergent must be thoroughly mixed and dissolved into the water. The pres-
ence of undissolved detergent particles in the cleaning solution can cause prob-
lems in the cooling system. The particles can be trapped in valves and flow
meters causing malfunctions to occur.
STEP 2
Drain system of all water.
Monitor the level of water that is returned to
the container to determine trapped water in system. To more easily drain
the system open all of the system and cabinet drain and vent valves.
Once draining is complete close all cabinet drain valves. The charge
pump can be reversed to aid in draining the system.
NOTE:
To facilitate draining one or more vent valves at high points in the system must be
opened.
STEP 3
Use a marker to note the level of the liquid in the container.
The
difference between this level and the previous low level is the amount of
liquid required to completely refill the system. Empty the container and
refill (to the same level) with clean distilled water.
STEP 4
Pour the cleaning solution through a porous cloth (to filter out
clumps of detergent) into the container containing clean distilled
water and mix thoroughly.
STEP 5
Use the charge pump to fill the system with the cleaning solution.
Monitor the sight glass to confirm fluid level and lack of air bubbles
before turning off charge pump
.
Insure that a static pressure of 10 psi is
achieved (with pumps off)
.
STEP 6
Run the system for 40 minutes.
Alternate pumps A and B for 20
minutes each.
STEP 7
Turn off pump.
Close bypass valve and open cabinet intake and outlet
valves to allow cleaning solution to flow through transmitter cabinet.
