IMPORTANT:
Completely read these instructions and warnings prior
to installing and operating your Kasco equipment.
This portable timer is designed to
CONTROL
the
connected equipment only.
THIS SWITCH IS NOT TO
BE USED AS A POWER DISCONNECT!
Unplug The
C-20 and the equipment it controls before servicing.
Mount at least 5 ft. from open water. Refer to your
de-icer owner’s manual for additional safety and
de-icer installation/operation instructions. The C-20
is designed to operate only ONE Kasco de-icer.
INSTALLATION:
The C-20 must be mounted upright on a vertical
surface or post. For the most accurate operation
do not mount in direct sunlight. Mount close to an
outdoor receptacle to allow slack in the C-20 power
cord. Mount high enough above ground level for easy
use and to prevent ground moisture/flooding from
damaging the C-20. Use corrosion resistant screws
to mount the C-20. One screw for the top hanger slot
and one for the bottom mounting tab to secure the
C-20. Insert your de-icer power cord through the hole
in the bottom of the C-20 enclosure. Allow enough
slack to prevent strain on the plug. You may also need
to provide a tether (another point to hold the cord
in place) to prevent your de-icer power cord from
slipping into the water. You can install the closure
plate provided by snapping into place from the outside
of the enclosure hole. Note: Install closure plate
with 3R (outdoor use) rating to maintain enclosure
environmental integrity.
UNDER NO CIRCUMSTANCES SHOULD
ANYONE ENTER THE WATER WHEN A UNIT
IS IN OPERATION.
SETTING THE TIMER & THERMOSTAT:
The C-20 energizes your De-icer only when both the
timer and thermostat turn on. The Indicator light will
illuminate when both timer and thermostat are on
(de-icer outlet is energized).

TIMER SETTING:
1. Push each tripper to the outer ring for every 15
minutes of activation time. Note: For most efficient
and effective De-Icing, do not set the timer in
segments of less than one hour activation time. (Set
4 trippers on together for 1 hour minimum.)
2. Turn timer dial clockwise until correct time-of-day
is aligned with “TIME NOW” arrow.
3. Set AUTO/ON switch to AUTO for automatic timer
control.
Note: Setting the timer switch to ON will allow the
de-icer to operate by the thermostat only (timer output
is always on).
THERMOSTAT SETTING:
Simply set the thermostat dial to the temperature you
want the de-icer to turn on. (Remember the timer must
also be set to ON or AUTO for the de-icer to energize.)
The thermostat has a 6°F ON/OFF differential. This
differential helps prevent short cycling of the de-icer.
Set the thermostat to the desired ON temperature and it
will shut off approximately 6°F above the ON setting.
Note: The C-20 control must acclimate to the outdoor
ambient temperature for proper operation. Allow
at least 1 hour for the C-20 to adjust to ambient
temperature.
OPERATING RECOMMENDATIONS:
Use the following tips and suggestions to assist in
customizing your settings for local conditions.
• De-icers will create small localized currents the
longer they run. Fewer and longer operation cycles
will prove to be more effective than more frequent
and shorter operating cycles.
• Fresh water freezes at 32°F, salt water at 28°F, and
