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 may be done if there is a sign of

clogging in the aeration chamber (e.g. abnormal increase in

recirculation flow).

(A) Air flushing procedure:

• Make sure the blower is in the aeration mode.

• Make sure a check valve or backflow preventer is present

for water 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 Figure 18)

• Make sure the blower is off.

• Close valve (2) all the way.

• Connect a water line to the aeration line as shown in

Figure 18.

• 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 air line to the blower.

• Set valves (1) and (2) back to the appropriate positions.

(See Recirculation Flow Adjustment, pg. 10)

Cleaning the recirculation line:

• Make sure the blower is in the aeration mode. If not,

change the mode by pressing the Manual Backwash

button.

• 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 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 20.

• Reset the gray valve (2) to its original position.

Foam formation

Make sure there is not an excess amount of foam on the

surface. If excessive foam is present it may indicate high

detergent usage. Meet with owners to inform and educate

them concerning excessive use.

Abnormal water level

If the water level exceeds the partition wall, clean the plastic

cage first with a brush, then check for possible clogging in the

filter media section. Clogs may be cleared by using a manual

backwash tool. The manual backwash tool may also be used

to eliminate a clog in the anaerobic chamber media as well.
