Diffused Aeration Systems

Installation ...
• On the following pages you will find detailed instructions for assembly and installation for
your system.
• The air diffuser should not be placed in the deepest part of the pond. Try to locate the dif-
fuser at approximately 2/3 to 3/4 of the deepest point (a 15' deep pond would have the
diffuser at approximately 10' to 12' deep). This allows the deepest water to remain cool
in the Summer and stay warm in the Winter.
• If you purchased your aeration system without weighted tubing, you will need to supply
small weights such as chimney bricks, pipe or rerod. Strap the weights securely around
the tubing to bring it to the bottom.
• If your pond freezes during the winter, be sure the tubing is buried leading into the pond.
If not, the ice can form around the tubing, kinking it or possibly shearing it off.
Operation ...
• All of our compressors are designed for continuous operation. It is not uncommon for
these compressors to run 24 hours per day for four to five years. The only maintenance
required is replacement of vanes or diaphragms when needed. All compressors have oil-
less motors. Never oil or lubricate the motors.
• The surface of the compressor will be hot during operation. This is normal — be careful
not to touch the compressor while it is running.
• If you are installing this system at a time when your pond is already stratified (warm on
surface, cold on bottom), you should be careful when first starting the aeration system.
If the stagnant water on the pond bottom is stirred up too fast, a temporary increase in
oxygen demand will occur and, in rare cases, a fish kill could result. If your pond is
severely stratified, you should only run your system one to two hours the first day. Each
day after that, increase the run time by one to two hours during the first week, run con-
tinuously after that. This will slowly mix the bottom water without a sudden depletion of
oxygen. Please contact us prior to start-up if you have questions.
• In addition to adding oxygen to your pond, one of the main benefits to an aeration sys-
tem is the circulation it creates. It takes hours for the maximum circulation to be
achieved, therefore we recommend running these systems continuously so that maxi-
mum circulation is sustained. Systems that operate a few hours each day will just get the
circulation going and then it is time to shut off.
Maintenance ...
•It is critical that the air compressors be protected from the weather. You will need to
provide a shelter for your compressor to protect it from rain, snow and other harsh ele-
ments. Be sure your shelter has adequate ventilation. Also be sure the compressor does
not sit directly on the ground, as the vibration from the motor will cause dust and dirt par-
ticles to be pulled into the motor and cause premature failure.
Thank you for your purchase!
Your aeration system will be a great benefit to the aquatic ecosystem in which you are plac-
ing it. The following are some important guidelines regarding the installation and operation
of your system.

PA10 Aeration System ...
The PA10 aerator features a 1/20th horse power contin-
uous duty air compressor, 50' of tubing and a pond dif-
fuser.
Once the air diffuser is assembled and the tubing is
attached, you are ready to install the diffuser 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 dif-
fuser 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 two airstones into the PVC manifold. Do not overtighten! Hand tighten only!
3.Slide one end of the tubing onto the barbed adapter coming out of the PVC manifold.
Clamp this connection using the clamp provided.
4.Position the PVC manifold and airstones onto the white plastic underlay. Use the plastic
straps provided to attach the manifold to the underlay.
5.Attach the other end of the tubing to the compressor and tighten.
After one or two years of operation, you will possibly notice a sudden drop in air bubbles.
This is a sure sign that the diaphram has cracked and needs replacing. Repair kit DC22RK
has all the items necessary to rebuild your compressor.
Be sure to clean the inlet air filter on your compressor regularly. Wash dirty air filters in
soapy water. Replacement filters are available.

PA33 Aeration System ...
The PA33 aerator features a 1/4 horse power con-
tinuous 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 diffuser
into the pond. Always unroll the tubing complete-
ly 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 installed 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 com-
pressor.
PA33 Packing List:
The flexible membrane dif-
fuser 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.
Be sure to clean the inlet air filter on your compressor regularly. Wash dirty air filters in
soapy water. Replacement filters are available.

PA50 and PA60 Aeration Systems ...
These aeration systems come with a continuous
duty compressor, 200 feet of hose and two air
diffusers.
Once the air diffuser is assembled and the tub-
ing is attached, you are ready to install the dif-
fuser. 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 possi-
ble.
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 installed 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 com-
pressor.
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.
PA50 and PA60 Packing List:
The PA50 and PA60 aeration sys-
tems are identical except for the
compressor. The PA60 compres-
sor has a higher pressure rating
for deeper water operation. All
other items and assembly are the
same for these two kits.
After one or two years of opera-
tion, you will possibly notice a sudden drop in air bubbles. This is a sign the compressor
needs new vanes. A rebuild kit is available to restore like-new performance.
Be sure to keep the air filter clean. Wash dirty air filters in soapy water. Replacement filters
are available.

• The PA100 system installs the same as PA75, it simply has five airlines instead of
four.
PA75HP, PA75 and PA100 Packing List:
The PA75 hp and PA75 aeration
systems are similar except for the
compressor. The PA75HP com-
pressor has a higher pressure rat-
ing for deeper water operation. All
other items and assembly are the
same for these two kits.
After one or two years of opera-
tion, 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 performance. Be sure to keep the air filter clean. Filters can be
washed in soapy water. Replacement filters are available.

Windmill Aeration System ...
The windmill pond aerator is an excellent alternative to
electric pond aerators. The windmill has a complete set of
instructions included with it. Please follow these instruc-
tions to assemble the windmill head and tower. We supply
the air hose and air diffuser for this windmill kit.
Note: A check valve is included with the windmill to go in
the airline underwater by the air diffuser. Our air diffuser
includes a built-in check valve so you will not need the one
included with the windmill.
When you get to page 5 in the instruction book, please fol-
low these instructions for the diffuser installation:
Fill base of air diffuser with sand or gravel. Screw mem-
brane diffuser into top of base. Attach end of tubing to
outlet and clamp. Unroll the tubing completely before
attempting to install the diffuser assembly in your pond.
Tubing needs to be
weighted to sink.
Usually a three to
five pound weight every six to eight feet is adequate.
Weights can be landscape bricks, rerod, etc., and
should be strapped tightly to the tubing with electric
ties. Omit this step if you are using self-weighted tub-
ing.
A 20' piece of black plastic hose is included with your
windmill. This tubing connects to the outlet on the
compressor at the top of the windmill and runs down
the tower to the ground. A connector is included to
connect to the 100' roll of tubing at this point.
After installing the manifold in the pond, connect the
other end of the vinyl tubing to the end of the black
tube coming off the windmill.
