PA33 Aeration System ...
The PA33 aerator features a 1/4 horse power
continuous duty air compressor, 100' of
tubing and a membrane diffuser. Once the
air diffuser is assembled and the tubing is
attached, you are ready to install the dif-
fuser into the pond. Always unroll the tubing
completely before installing the diffuser. The
diffuser can be lowered into your pond with a rope. Often a float, such as a duck
decoy or a milk jug, will be used so retrieval of the diffuser is possible.
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.
The flexible membrane diffuser is buoyant (even if weighted hose is used) unless the
base is filled with sand or gravel. Be sure to fill base at least 2/3 full. After one or two
years of operation, you will possibly notice a sudden drop in air bubbles. This is a
sign that the piston rings have cracked and need replacing. Repair kit RP74RK has
all the items necessary to rebuild your compressor.
