STEP 8
Run the system for an additional 20 minutes.
Alternate pumps A and
B for 10 minutes each. Note flow rate of system.
STEP 9
Drain the system
. To drain the system open the drain hoses and the
system vent valves. Once draining is complete close all drain and vent
valves.
STEP 10
Dispose of cleaning solution in container and rinse.
Refill the
container with clean distilled water.
STEP 11
Clean the pump module strainer screen.
The strainer is located near
the pressure gauge on the return side of the pump module.
2.11.4 System Flushing
Flush the system to remove the cleaning solution. Before the initial transmitter
operation the cooling system must be purged of all cleaning solution residue.
The flushing is accomplished by alternately filling, running and draining the system,
two to four (or more if needed) times using distilled water. The following steps outline
the flushing process.
NOTE:
The length of flushing time and number of fill/drain cycles needed to achieve
desired water quality will vary with system size and the amount of residual
(trapped) liquid in the system. Residual liquid is trapped in the system and cannot
be removed when the system is drained. Smaller systems with less residual liquid
may require a lower number of flush cycles.
STEP 1
Fill system with distilled water
(see appendix section "B.1 Coolant and
Water Recommendations" on page B-1)
.
a.
Confirm previous estimates of the amount of liquid required to fill
the system.
STEP 2
Run system for approximately 20 minutes.
Alternate pumps A and B
for 10 minutes each.
STEP 3
Drain system
. Drain valves must be opened at each low point in the
system, along with the vent valves at the system high points, to ensure
full drainage.
STEP 4
Repeat above steps (flushes) until coolant is clear of contaminants
and detergent residue.
Typically 3 distilled water flushes are needed.
