AERATION CHAMBER CLEANING
1. Aeration.
The aeration system must be flushed every maintenance
visit. There are two flushing methods; (A) Air flushing
and (B) Water flushing. Air flushing must be done
every maintenance visit. Water flushing must be done if
there is a sign of clogging in the Aeration Chamber (e.g.
abnormal increase in recirculation flow).
(A) Air flushing procedure:
• Close gray recirculation valve (2) all the way. (0%)
• Rotate blue aeration valve (1) back and forth from
the 0% to the 100% position several times to flush.
• Set valves (1) and (2) back to the appropriate
positions. (See Recirculation Flow Adjustment, pg.
10)
(B) Water flushing procedure: (See Fig. 20)
• Make sure that the blower is off.
• Close valve (2) all the way.
• Connect a water line to the aeration line after
the switching valve, as shown in Fig. 20.
• Gradually open the water faucet and introduce water into
the system.
• Rotate valve (1) back and forth from the 0% to
the 100% position several times to flush.
• Turn off the water, remove the water line, and
reconnect the airline to the blower.
• Set valves (1) and (2) back to the
appropriate positions.
(See Recirculation Flow Adjustment, pg. 10)
(C) Cleaning the recirculation line:
• Open the gray recirculation valve (2) to 100%.
• Flush water through the recirculation line for several
seconds.
• Turn off the recirculation by rotating the gray valve (2) to
0%.
• Make sure that the blower is off. Allow the system to
relax for a few seconds.
• Repeat this cleaning method three times.
• A hose or brush can also be used to clean the
recirculation line. See Figure 21.
• Reset the gray valve (2) to its original position.
