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?
• Has there been any electrical problems in the area
recently?
“My Aerator 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.
“My Aerator hums, but will not start. When I spin the prop
with a stick, it starts up.” (for single phase units only)
This indicated a problem with the Starting Ca-
pacitor. Each Kasco Aerator is equipped with a Starting
Capacitor to get the unit going when it is first plugged in.
If it is operating, but not spinning and can be started by
spinning the prop with a stick, the Starting capacitor needs
to be replaced by an Authorized Repair Center.
“My Aerator turns itself off and back on without the timer
and without tripping the GFI breaker.” (for single phase
units only)
Each Kasco unit has a Thermal Overload built in
that will turn the unit off when it overheats. Once the unit
has cooled down, it will start back up. If you are noticing
these symptoms, the unit should be unplugged immediately
because the Thermal Overload will continue to turn on
and off until it burns out and damages the motor. The unit
should be unplugged and taken out of the water to find the
cause of the problem. The problem could be one of many,
such as, low water levels, build-up on the unit to prevent
heat dissipation, something inhibiting the free rotation of
the shaft, etc. If something is caught in the unit or there is a
build-up on the unit, remove the debris and, if caught early
enough, the unit should be fine. Contact a Kasco represen-
tative before restarting the unit.
“My Aerator flow seems to fluctuate and/or be less than
usual.”
This can occur because of a few different reasons.
Most of the time, this symptom is caused from unit being
clogged with debris. A mat of weeds, many leaves, plastic
bags, etc. can clog up the unit and cause it to be starved of
water. If the unit does not have the proper amount of water,
the flow or pattern will fluctuate up and down and look spo-
radic. If you are seeing these symptoms, unplug the unit
and clean away the debris that is clogging up the screen.
Another possibility if these symptoms are noticed, is a
chipped or damaged prop that is causing the unit to wobble
and not pump properly. When the unit is unplugged, check
the prop for damages and replace if damage is found.
“The GFI breaker trips randomly and sporadically. Some-
times it is a few hours of operation, other times it can be
days or weeks.”
This is referred to as a Nuisance Trip. This usu-
ally occurs where the unit is installed a great distance from
the initial electric service on the property where the ground
stake is placed. It is caused by either induced current in
the ground wire or a base voltage difference due to soil pH
levels. A possible reso- lution to the problem, contact an
electrician and install a local grounding stake. This may
eliminate the induced current and any base voltage differ-
ences.
