DIFFUSER INSTALLATION
The effectiveness of the Robust-Aire™ system depends on the location of the diffusers in the pond. Place the
Robust-Aire™ Diffusers equidistant from each other at a depth that is representative for most of the pond.
Please contact Kasco with any questions about placement or system operation.
CAUTION: Do not use boats that tip easily for installation.
Always wear a personal flotation device.
1.
Kasco recommends marking the location of each diffuser at the surface with a buoy.
2.
Unroll the SureSink™ Tubing on shore to remove any twists or knots. Performance will decrease if the
tube is not properly uncoiled.
3.
Each tubing length is 100 feet. If more than one length of tubing is required to reach a diffuser location,
connect any additional tubes according to the SureSink™ Tubing instructions. Unroll these tubes as you
did the first tube. You can load multiple rolls of tubes into a boat and connect them as needed while
making your way to the proposed diffuser location. You can also connect any number of 100’ lengths
together and have someone assist in feeding it from shore. Cut off any excess tubing at the shore before
connecting to the compressor.
4.
Drop the loose end of the tubing near the compressor cabinet. Allow a few extra feet of tubing to work
with so the tube will reach the cabinet after trenching between the shore and the compressor.
5.
Drive the boat in reverse to keep tubing clear of the propeller and slowly make your way to the marking
buoy, placing the tubing as you go.
6.
Once you reach the marked buoy, thread a rope through the two holes of the diffuser base. Pull through
until the midpoint of the rope is at the diffuser base.
7.
While holding the two ends of the rope, gently lower the diffuser assembly into the water.
8.
Continue slowly lowering the assembly until it reaches the bottom of the pond. The diffuser will always
land right side up.
9.
The Robust-Aire™ Diffuser should now be seated properly on the bottom of the pond. You can remove
the rope by pulling on one end. For ease of future maintenance, Kasco recommends leaving the rope
looped through diffuser base and tying both ends to a marker buoy or duck decoy. This will allow you to
easily locate diffusers and pull them to the surface for maintenance.
10.
Repeat the process for additional Robust-Aire™ Diffuser locations.
