GETTING TO KNOW YOUR
KoiAir
™
SYSTEM
IMPORTANT INFORMATION
• 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 unit where people may step on the power cord.
• Never override electrical or mechanical interlock devices.
• Never attempt maintenance functions that are 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.
DANGER
• Read the operating instructions carefully.
• To reduce the risk of electric shock, connect only to a properly grounded grounding-
type receptacle.
• THIS UNIT IS TO BE USED IN A CIRCUIT PROTECTED BY A GROUND FAULT CIR-
CUIT INTERRUPTER.
• This unit has not been investigated for use in swimming pool areas.
• Disconnect unit from power source before handling.
• Repair and exchange of cable must be carried through by the supplier/manufacturer.
DANGER
Operating in freezing conditions on an ice-covered water garden will cause open water
areas, even in freezing conditions. Also, the ice thickness around these open areas will
be much thinner than the ice over the remainder of the pond. Injury or fatality may re-
sult from falling through the ice.
Airmax
®
strongly recommends that this danger of
thin ice around the diffuser site be clearly posted at frequent intervals.
Owner as-
sumes all responsibility for operating KoiAir
™
Aeration Systems during winter months.
If you choose to turn off your system for the winter do the following:
• Unplug the system and remove the diffuser(s), airline(s) and compressor.
• Store in a dry area protected from the elements such as a garage or basement
(climate control recommended).

INSTALLING YOUR KoiAir
™
AERATION SYSTEM
1
Decide on a location for the KoiAir
™
compressor. It’s important to
elevate the compressor a few inches above ground level, making
sure the compressor is above the pond’s water surface. If power is not
available at the pond’s edge, the compressor may be located at the power
source and extra airline can be added (up to 100’) to reach your desired
diffuser location.
NOTE:
It is recommended that the compressor be covered
and not exposed directly to the elements. This can be accomplished by
purchasing a faux rock cover (Item #510330). If you decide to use your own
cover, make sure it will keep water from coming in direct contact with the
compressor and that there is plenty of ventilation.
2
Connect the self-weighted
airline to the outlet on the com-
pressor as well as to the diffuser.
3
Find a location in your water garden to place
the diffuser. It’s recommended to place the
diffuser away from the deepest point, leaving an
area for the fish to habitat. If you have two diffus-
ers, equally distribute them throughout the water
garden, but away from the deepest point. Do not
exceed 4’ in depth when placing your diffusers.
Depths in excess of 4’ will greatly reduce airflow
to the diffuser and cause excess strain on the
compressor reducing its life expectancy.

Adjust control valves
to balance airflow between
diffusers, if desired. It is not
necessary to have even airflow
between diffusers, nor will
it have any effect on the life
expectancy of the compressor.
