DIFFUSER BASE PLACEMENT
Correct placement of the Stainless Steel Diffuser Base is critical. The ability of the aeration
system to affect your pond is dependent upon the position of the Diffuser.
1. Uncoil the roll of self-weighted tubing along the shoreline of your pond. Make sure the
tubing has no twist or tangles to make it easier to install the Stainless Steel Diffuser Base.
2. While holding the Stainless Steel Diffuser Base, begin pulling to the desired location in
pond. Make sure membrane diffuser is upright.
3. Follow SYSTEM START-UP PROCEEDURES that follow.
SYSTEM START-UP PROCEDURES
The purpose of the Shallow Pond Diffused Aeration System is to circulate the pond's entire
water column. This circulation will increase and maintain oxygen levels and eliminate drastic
temperature fluctuations. To avoid an over saturation of Hydrogen Sulfide and Carbon
Dioxide and the potential for a fish kill, the procedures below must be followed.
 Turn on the system and operate for 15 minutes.
 Turn off the system for the remainder of the day.
 Restart the system the next day and operate for 30 minutes.
 Turn the system off for the rest of the day.
 Each day double the operating time from the previous day until the system is running
continuously. This should take approximately 8 days
WINTER OPERATIONS & PRECAUTIONS
DANGER: If you choose to operate your aeration system through the winter:
 Operating in freezing conditions on an ice-covered pond will cause large open water
areas to remain at the boil sites. In addition, 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 people, snowmobiles, etc. falling through the ice. ACI strongly recommends
that this danger of thin ice around the boil area be clearly posted in various areas. Owner
assumes all responsibility for operating aeration systems during winter months.
 To prevent the risk of cooling the entire water column in the pond, the Diffuser(s) should
be moved to a shallower portion of the pond (typically one-half of the depth of the original
placement) and operated there until spring thaw. Moving the Diffuser to shallower water
will allow warmer water to remain in the lower regions of the pond and prevent the water
from becoming too cold for your fish.
 The self-weighted tubing on shore must be buried below the frost line or insulated. It
should also be sloping downhill without any dips in the line.
If you choose to turn off the system for the winter:
 Disconnect the compressor from the air tubing and bring it inside to keep it from freezing.
