2. Safety
The circulation of poor quality, low oxygen, deep water to the pond’s surface can introduce harmful gases
and by-products into the previously healthy upper regions of the water column. These by-products can
make the upper regions unfit for aquatic life and could result in fish-kill.
To Prevent Initial Fish-Kill:
Follow this procedure anytime system has been shut-off for an extended period of time.
Day 1: Run system for 30 minutes; turn system off for remainder of day.
Day 2: Run system for 1 hour; turn system off for remainder of day.
Day 3: Run system for 2 hours; turn system off for remainder of day.
Day 4: Run system for 4 hours; turn system off for remainder of day.
Day 5: Run system for 8 hours; turn system off for remainder of day.
Day 6: Run system for 16 hours; turn system off for remainder of day.
Day 7: Begin running system 24 hours/day, 7 days/week.

• Flathead screwdriver
• Sharpie
®
Marker
Location
• Locate cabinet on a solid support with adequate strength for weight of unit.
• Locate cabinet away from irrigation sprinklers.
• Wear a Coast Guard-approved life jacket; follow all safety and caution guidelines.
WARNING: All compressor cabinets must be located above the water level.
4. System Installation
1.
Decide on a location for the cabinet and prep
ground. May be placed several hundred feet from
shoreline (using direct burial airline) if power is not
available at shore.

6 Easy Steps!
2.
Option 2 Only:
Excavate trench to a minimum
of 8” of depth for direct burial line. Place and backfill
all direct burial airline (one line per diffuser).
3.
Option 2 Only:
Connect direct burial airline to
EasySet
™
self-weighted airline.
4.
Connect diffuser to airline. Extend EasySet
™
self-weighted airline to proper location. Place dif-
fuser. To ensure proper placement, use nylon rope.
Plates should be located towards the deepest part
of the pond.

5.
Connect airline to flex lines supplied with cabinet.
Open cabinet, plug compressor and cooling fan into
power control. Plug power control cord into power
outlet. Flip power switch to the ON position.
6. Bubbles should be noticeable from all diffuser loca-
tions. When more than one diffuser is installed, adjust
valves for maximum performance. Once adjustments are
made, wait several minutes to see results at the diffuser
location(s). Deeper placement of plate(s) and longer
runs of tube will require more flow.

Option 1: When power source is available at pond’s edge, simply connect one end of EasySet
™
Airline to flex-hose and other end to diffuser plate.
Steps 2 & 3 below are not necessary using this option.
Option 2: When power source is not available at pond’s edge, place SilentAir
™
Cabinet next to
nearest power source. Trench Direct Burial Airline (sold separately, ½” standard irrigation pipe may
be substituted) from flex-tube to pond’s edge; then connect to EasySet
™
Airline and run to diffuser
plate. Each diffuser will be a separate run of airline. Each run may not exceed several hundred feet.

WARNING – Improper installation of the grounding plug is able to result in a risk of electric shock.
When repair or replacement of the cord or plug is required, do not connect the grounding wire to either
flat blade terminal. The wire with insulation having an outer surface that is green with or without yellow
stripes is the grounding wire.
For 120 VAC products:
This product is for use on a nominal 120V circuit, and has a grounding plug similar to the plug illustrated
in sketch A in Figure below. A temporary adapter similar to the adapter illustrated in sketches B and
C may be used to connect this plug to a 2-pole receptacle as shown in sketch B when a properly
grounded outlet is not available. The temporary adapter shall be used only until a properly grounded
outlet (sketch A) is installed by a qualified electrician. The green colored rigid ear, lug, or similar part
extending from the adapter must be connected to a permanent ground such as a properly grounded
outlet box cover. Whenever the adapter is used, it must be held in place by a metal screw.
For 230 VAC products:
This product is for use on a circuit having a nominal rating more than 120 V and is factory-equipped with
a specific electric cord and plug for connection to a proper electric circuit. Only connect the product to
an outlet having the same configuration as the plug. Do not use an adapter with this product. When the
product must be reconnected for use on a different type of electric circuit, the reconnection shall be
made by qualified service personnel.
SAFETY
• Read all operating instructions carefully.
• To reduce the risk of electric shock, connect only to a properly grounded, grounding-type receptacle.
If in doubt, have the outlet checked by a qualified electrician.
• This unit is to be used in a circuit protected by a ground fault circuit interrupter (GFCI).
• Disconnect unit from power source before handling or maintenance.
• Repair or exchange of cable/power cord must be carried through by the supplier/manufacturer.
• This unit has not been investigated for use in swimming pool areas.
CAUTION
• Never connect to an extension cord. This may result in equipment failure.
• Do not allow anything to rest on the power cord.
• Do not place the cabinet where people may step on the power cord.
• Never override or “cheat” electrical or mechanical interlock devices.
• Never attempt any maintenance function that is not specified in the user manual.
• Never operate the system if unusual noises or odors are detected.
Disconnect the power cord from
the outlet and call for service.
GROUNDING INSTRUCTIONS
This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk
of electric shock by providing an escape wire for the electric current. This product is equipped with a
cord having a grounding wire with an appropriate grounding plug. The plug must be plugged into an
outlet that is properly installed and grounded in accordance with all local codes and ordinances.
Winter Operation
Owner assumes all responsibility for operating Airmax
®
Aeration System during winter months.
Operating in freezing conditions on an ice-covered pond will cause large open water areas at diffuser
sites. Ice thickness around open areas will be much thinner than the surrounding areas. Airmax
®
strongly recommends that “Danger - Thin Ice” be posted at frequent intervals around pond. Diffuser
plates should be moved out of the deepest points of pond to allow a safe zone for fish dormancy and to
avoid “super cooling” effect.
If you choose to turn your system off for the winter, do the following:
• Unplug your aeration system.
• Disconnect compressor flex-tube(s) from airline(s).
• Cover airline ends with included caps to prevent debris from entering airline.
• Move cabinet and compressor inside to keep dry.
• When turning system back on in spring, airlines may contain ice.
• Use 1 cup denatured alcohol in the airline running out to each plate.
• Turn on compressor to push through line and free any ice blockage.
• Follow initial startup procedure to avoid “shock” in the pond.
WARNING: Wrap cord neatly in or under enclosure when not in use to prevent off-season damage.
