properly is from a setup error. The C-20 Time and
Temperature Control must have BOTH the Timer
AND Thermostat activated. (The timer must be in an
ON position and the outside air temperature must be
lower than the setting on the thermostat.) Keep in
mind, the thermostat may take a few hours to adjust
to the outside temperature. Make sure the C-20 is not
in direct sunlight which would heat up the thermostat.
If both are activated, the small light in the upper left
hand corner of the control box will be lit up. A test
that can be done is to put the C-20 in the freezer for a
couple hours and then test it. If your outdoor tempera-
ture is cold enough, you can set up the C-20 and plug
a light into it. Watch it throughout the evening to see
if and when the light comes on. If all else fails, please
contact Kasco for assistance.
cold for an extended period without running, it may
take a minute for the prop to get to full speed once
power is supplied.
“My De-icer hums, but will not start. When I spin the
prop with a stick, it starts up.”
This indicated a problem with the Starting
Capacitor. Each Kasco De-Icer is equipped with a
Starting Capacitor to get the unit going when it is fi rst
plugged in. If it is operating, but not spinning and can
be started by spinning the prop with a stick, the Start-
ing capacitor needs to be replaced by an Authorized
Repair Center.
“My De-icer turns itself off and back on without the
timer and without tripping the GFI breaker.”
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 fi nd 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 dissipa-
tion, 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 fi ne. Contact a Kasco
representative before restarting the unit.
“My De-Icer fl ow seems to fl uctuate and/or be less
than usual.”
This can occur because of a few different rea-
sons. 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 fl ow or pattern will fl uctu-
ate up and down and look sporadic. If you are seeing
these symptoms, unplug the unit and clean away the
debris that is clogging up the screen. Another pos-
sibility 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.
“My C-20 does not seem to be working properly”
Most of the time, a C-20 that is not working
