Thank you for your purchase!
This aeration system will be a great benet to the aquatic ecosystem in which
you are placing it. Please read through the following guidelines completely
before installation and operation of your aeration system.
Safety Warnings
• Use extreme caution when operating in winter. Danger due to thin ice can
cause drowning. Unseen currents can cause thin ice in areas long distances
away from diuser operation. Provide adequate warning for others using a
pond with a diused aeration system.
• The surface of the compressor will be hot during operation. This is normal
— be careful not to touch the compressor while it is running.
• Units must be connected to GFCI protected outlets.
• Avoid using extension cords to operate compressor.
• Keep children or pets away from operating units
• Always disconnect power when servicing system.
• Relieve pressure from system before servicing.
Operation
• All of our compressors are designed for continuous operation. It is not
uncommon for these compressors to run 24 hours per day for three to ve
years. The only maintenance required is replacement of wearable items
(diaphram, piston ring, vanes, etc.) when needed and keeping lter clean.
CAUTION: All compressors in these kits are designed for oil-free opera-
tion. Never oil or lubricate the compressors.
• In addition to adding oxygen to your pond, an aeration system creates a
circulation action. It takes hours for the maximum eect to be achieved,
therefore we recommend running these systems continuously so that maxi-
mum circulation is sustained.
Summer Time Start Up
CAUTION: If you are installing this system at a time when your pond
is already stratied (warm on surface, cold on bottom), you should be
careful when rst 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 sh kill could result. If your pond is severely stratied, you
should only run your system one to two hours the rst day. Each day after that,
increase the run time by one to two hours during the rst week, run continuously
after that. This will slowly mix the bottom water without a sudden depletion of
oxygen.

Installation Precautions
• The air diuser should not be placed in the deepest part of the pond. Try
to locate the diuser at approximately
2
/
3
to
3
/
4
of the deepest point (a 15'
deep pond would have the diuser 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 pos-
sibly shearing it o.
CAUTION: Locate all utilities before digging to ensure safety of in-
staller and others.

Compressor Placement
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 elements.
• Be sure your shelter is adequately ventilated. A cooling fan may be neces-
sary in warmer climates. Several cabinet options with fans are available.
• Be sure the compressor does not sit directly on the ground, as the vibration
from the motor will cause dust and dirt particles to be pulled into the motor
and may cause premature failure.
• If operating compressor in freezing climates do not place compressor in
“heated” buildings. Warm air holds more moisture. This warm air may con-
densate and freeze in the colder outdoor line.
• Ensure that compressors are placed where
they will not become ooded with water.
• If possible, shaded areas are preferred.
• In areas with limited electrical supply,
compressors can be placed long distances
from the pond edge. A remote access valve
assembly can be fed from the compressor
with properly sized tubing.
Cabinet Placement
• If installing a Sentinel Deluxe Aeration System, place the cabinet on a level,
unobstructed base to ensure the compressor does not overheat.
• A post mounted cabinet should be kept free from high weeds and other
obstructions to ventilation system.
Diuser Placement
The amount of surface area an aeration system will eectively cover is greatly
dependent on two factors - DEPTH and SHAPE. The deeper an air diuser is
located, the more boiling action it will create and a larger area will be aerated.
The diagram below shows how much surface area is eectively aerated per
air diuser at various depths. Ponds that are irregular or odd shaped will also
reduce size of aeration area — call our technical department for additional help.
Example:
Our PA34 pond aerator
would aerate only 1
/8
of an acre if operated
in 4' deep water, while
aerating up to 1 acre
if operating in 12' - 16'
deep water.
The shape of a pond aects
the amount of diusers
needed. Irregular shaped
ponds often require multiple
diusers to adequately aerate
entire water column.

General Assembly Instructions
1. Unpack the aeration system to ensure all parts were received. If a shortage
occurs, please notify EasyPro immediately.
2. Assemble diusers, detailed instructions included with each diuser assem-
bly. NOTE: Video walk-through of diuser assembly and installation found
at: easypropondproducts.com/diuser-assembly
3. For Sentinel Deluxe units, the lter and valves are connected to the com-
pressor.
For basic kits you will need to install the inlet lter and outlet assembly. On
all basic kits, remove the compressor from the box and install the supplied
feet. Also, remove the colored inserts from the ports on the head of the
compressor. Threaded plugs stay on Stratus SRC compressors.
4a. For PA34/65/66 style kits (1/4 and 1/2 hp Stratus SRC compressors)
5. Unroll the entire roll of tubing. It is recommended that the diuser be in-
stalled at this point. This will allow you to trim any unused tubing before at-
taching to the compressor. Use clamps to secure tubing to outlet assembly.
6. Open the valves on the outlet assembly to their full open position. Plug the
compressor into a GFCI outlet and adjust each valve to equal the air ow to
each diuser. This equalizes air ow between diusers with dierent operat-
ing depths and/or tubing lengths.
PA34
PA34-2 PA66
4b. For PA83/86/90 style kits (3/4 hp Stratus SRC compressors)
(1) Thread lter into
“INLET” port.
(2) Thread quick
disconnect section
into “OUTLET” port.
(3) Install remainder of
outlet assembly to
quick disconnect
section.

Maintenance Guidelines
• Keep your compressor and intake lter clean. Any excess dust and debris
on motor or air intake may signicantly shorten the life of the compressor.
• Diusers may need regular cleaning in certain water conditions. This may be
every two to ve years.
• Compressors may need to be rebuilt if running but no longer “pumping air.”
Contact your EasyPro dealer for compressor rebuild kits.
• If lines become frozen, a small amount of denatured alcohol can be run
down the frozen line to thaw it out. The small amount of alcohol will not
harm sh or biological processes in your pond.
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 piston cup or vanes. Rebuild
kits are available to restore like-new performance. Be sure to keep the air lter
clean. Replacement lters are available.
