MAINTENANCE RECOMMENDATIONS
UNDER NO CIRCUMSTANCES should anyone enter the water while equipment is operating.
The following maintenance procedures can ensure many years of quality performance from your Kasco
aerator and reduce the need for more costly repair work.
Proper Installation
Proper installation of Kasco equipment will include a power source with Ground Fault Interruption (GFI).
Ground fault interrupters are a safety feature that can also alert you to electrical leaks in the equipment. It is
extremely important to test the GFI upon installation, following each re-installation, and monthly thereafter
to ensure proper operation. If you have repeat/consistent trips on your ground fault, disconnect the equip-
ment and remove it from the water. Inspect the power cord for damage and call Kasco Marine at 715- 262-
4488 for further instructions.
Observation
Operating equipment should be observed on a regular basis (daily, if possible) for any reduction or variation
in performance. If you observe a change in performance, disconnect the equipment from its power source
and inspect for any material that may have clogged the system or wrapped around the shaft of the motor,
especially plastic bags and shing line. Even though Kasco aerators are among the most clog-resistant on
the market, it is impossible to protect against all items that can clog equipment and still maintain a ow of
water. These materials can be very damaging to the equipment under continuous operation and must be
removed as soon as possible.
ALWAYS UNPLUG THE UNIT BEFORE ATTEMPTING TO REMOVE CLOGS.
Winter Storage
In regions where there is signicant freezing in the wintertime, remove the aerator from the water to
protect it from the expansion pressure caused by ice. In many areas, aerators will keep some amount of
ice open through the winter. However, when the water is thrust into the air, it is exposed to the colder air
temperatures longer and can actually make ice thicker on the pond/lake. Storage over winter is best in a
location that is out of the sun and cool, but above 32 degrees Fahrenheit. During the oseason, store units
upside down (with the oat down) if they are going to be sitting for long periods of time. Units that sit up-
right on a shelf for many months, or even years have a greater likelihood of seals drying out. Storing units
upside down will help to ensure oil is lubricating the seals without damaging the propeller guard.
Cleaning
Aerators should be removed from the water at least once per year (at the end of the season in cold climates)
to clean the exterior of the system, especially the stainless steel motor housing (can). The motor housing
is the surface that dissipates heat into the water, and any algae, calcium, or other build-up will become an
insulator that blocks heat transfer. In warmer regions, Kasco recommends removing the motor and cleaning
it at least two to three times per year, depending on conditions. In most cases, a power washer will be su-
cient if the unit and algae are still wet. Avoid power-washing the mechanical seal area directly.
