Thank you for your purchase! This aeration system will be a great benefit 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 •...
Installation Precautions • See next page for compressor placement details. The air diffuser should not be placed in the deepest part of the pond. • Try to locate the diffuser at approximately 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.

Diffuser Placement The amount of surface area an aeration system will effectively cover is greatly dependent on two factors - DEPTH and SHAPE. The deeper an air diffuser 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 effectively aerated per air diffuser at various depths.
Unroll the entire roll of tubing. It is recommended that the diffuser be installed at this point. This will allow you to trim any unused tubing before attaching to the compressor. Use clamps to secure tubing to outlet assembly. 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 flow to each diffuser.
