TROUBLESHOOTING TIPS
Below are some helpful troubleshooting tips. If a problem occurs, please double-check the assembly and
installation instructions as well as the instructions for the control panel. More troubleshooting tips can be
found at www.kascomarine.com
“My aerator or circulator trips the ground fault interrupter in the C-85 or C-95.”
This is the most common symptom of several possible problems. To correctly diagnose the problem, you
will need to collect more information. A Ground Fault Interrupter (GFI) breaker that trips can indicate an
electrical service problem, water contamination in the unit and/or cord, bad breaker, control box problems,
motor problems, etc. Try to find out the answers to these questions before you contact Kasco to narrow
down the problem.
•
How long does it take to trip the breaker?
•
Does it always take the same amount of time to trip?
•
How many times has it tripped?
•
Have there been any recent electrical problems in the area?
“My aerator or circulator seems to run slowly.”
This can also be a symptom of several possible problems. There could be an electrical problem where the
unit is not getting the proper voltage. This could also indicate a problem with the motor of the unit, which
needs to be looked at by an Authorized Repair Center. Check that the unit is receiving the proper voltage,
and, if so, contact Kasco for further steps.
Seal And Oil Replacement
This is a sealed motor assembly, and seals will wear out over time (similar to brake pads on a car). Replac-
ing the seals and changing the oil after three years may add longevity to the operation of the motor, saving
you the cost of more expensive repairs. In warmer climates where the aerator runs most or all of the year,
it is a good idea to replace seals more regularly than you would need to in colder climates where the unit is
removed from the water for several months.
Sacrificial Anode
A sacrificial anode is supplied on the shaft of all aerators for protection of the equipment from corrosion
and electrolysis. The anode should be updated (replaced) if reduced to half the original size or if white in
color. Corrosion from electrolysis is more commonly associated with saltwater or brackish water, but as a
matter of precaution, it is important to periodically check the anode in all installations (at least every two to
three months). Seal replacement and all other repair services should be performed by Kasco Marine or a
Kasco Authorized Repair Center. Any alterations or changes made to Kasco units by an unauthorized source
will void the warranty. This includes tampering with the unit, power cord, and/or control box. Please contact
Kasco Marine, Inc. at 715-262-4488 for your nearest Authorized Repair Center.
