PA75 and PA100 Aeration Systems ...
The PA75 system uses a 3/4 horse power high-volume
compressor with 800 feet of tubing
and four air diffusers. The maxi-
mum operating depth is 18 feet. The
PA100 system uses a 1 horse power
compressor with 1000' of tubing and
five air diffusers, maximum operating
depth is 18'.
Assembly:
1.
Unpack all the parts. Compare parts with packing list below to ensure all parts
were received. If a shortage occurs, please notify us immediately.
2.
Screw the round rubber membrane diffuser into the PVC base. Fill base with
sand or small stone.
3.
Slide one end of the tubing onto the barbed adapter on the PVC base and
secure with a clamp (provided).
4.
Attach the 2' piece of flex pipe into the outlet side of the compressor.
5.
Unroll the entire roll of pipe. It is recommended that the pond diffuser be in-
stalled at this point. This will allow you to trim any unused pipe before attaching
to the pump. Once installed and trimmed, attach the other end of the tubing to
the flexible hose on the compressor.
6.
Connect the valved outlet assembly to the compressor.
7.
Connect the tubing to the flex hose on the compressor. Once the compressor is
running, you may have to adjust the valves to equal the air flow to each diffuser.
This corrects the difference in air flow caused by a difference in operating depth
and/or tubing lengths.
•
The PA100 system installs the same as PA75, it simply has five airlines instead
of four.
After one or two years of operation, you will possibly notice a sudden drop in air
bubbles. This is a sign the compressor needs new vanes. A rebuild kit is available
(Part #RV75V for 3/4 HP compressor, RV100V for 1 HP) to restore like-new perfor-
mance. Be sure to keep the air filter clean. Filters can be washed in soapy water.
Replacement filters are available.
