•  Disconnect unit from the power source before handling.
• Repair and exchange of cable must be carried through by the supplier/manufacturer.

WINTER OPERATION:

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 result from falling through the ice. Airmax strongly recommends the danger of thin ice around the diffuser site be clearly posted at frequent intervals. The owner assumes all responsibility for operating KoiAir Aeration Kit during the 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 Decide on a location for the 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 the compressor be covered and not exposed directly to the elements. This can be accomplished by purchasing a small TrueRock™ 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 there is plenty of ventilation.

2. Connect The Airline
   Single Diffuser Systems: Connect the weighted airline to the outlet on the compressor using the 21/4” rubber connector and included spring clamps. Connect the other end of the airline to the diffuser. No clamp is needed on the diffuser end.
   Multiple Diffuser Systems: Connect the included 21/4” rubber connector to the compressor and use one of the squeeze clamps to keep it in place. Connect the bottom of the three-way air manifold to the rubber connector and hold in place with the remaining squeeze clamp.  Next, using the weighted airline, measure the distance from the compressor to the approximate location of your diffuser. Ensure to compensate for the depth of the pond. Cut the weighted airline to the appropriate lengths and connect them to the three-way air manifold as well as the diffusers. No clamps are needed for airlines. GETTING TO KNOW YOUR KoiAir AERATION SYSTEM:****

3. Place Your Diffuser(s)
Find a location in your water garden to place the diffuser. If you have two diffusers, distribute them equally throughout the water garden. Do not exceed the max depth rating of 4’ when placing your diffusers.  Depths in excess of this rating will greatly reduce airflow to the diffuser and cause excess strain on the compressor reducing its life expectancy. In case of extreme temperatures (hot or cold), it is recommended to relocate plates from the deepest points of your pond.

4. Adjust Your Valves
   (Systems with Multiple Diffusers Only)
   Adjust three-way air manifold 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. Valve positions are as follows: A. Valve Pointing Down: Air Flow comes up from the bottom and goes left.
   B. Valve Pointing Between Bottom and Right: Air Flow comes up from the bottom and goes left and right.
   C. Valve Pointing Right: Air Flow comes up from the bottom and goes right.

MAINTENANCE SAFETY:

• Always use parts that are supplied or approved by Airmax. The use of other parts may result in poor performance and could create a hazardous situation.
• Always unplug the system from the outlet and refer servicing to a qualified electrician under the following  conditions:
  1. When the power cord is damaged or frayed.
  2. If the compressor is producing unusual noises or odors.
