Installation Precautions
• The air diffuser should not be placed in the deepest part of the pond. Try
to locate the diffuser at approximately
2
/
3
to
3
/
4
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.
• 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 off.
CAUTION:
Locate all utilities before digging to ensure safety of in-
staller and others.
