Kasco C20 User manual

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/ooding 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 Thermostat De-icer
OFF OFF = OFF
ON OFF = OFF
OFF ON = OFF
ON ON = ON
TIMER SETTING:
1. Push each tripper to the outer ring for every 15
minutes of activation time. Note: For most efcient
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

and cycle the De-icer on temperature.
• To bypass the thermostat and operate only on
time, set the thermostat to its highest temperature
setting. Use the timer settings to cycle the de-icer.
Note: If the ambient temperature rises above the
thermostat highest setting, it will shut off the
de-icer.
• When not in use (summer time), store the C-20
indoors away from salt air. This will help extend
the life of the C-20 controller.
• Operate with the door closed to keep salt air away
from internal components.
• Mount the C-20 out of direct sun light. This will
prevent excessive internal heating of the controller.
Internal heating may prevent the C-20 from
operating correctly.

Kasco Marine, Inc. warrants the C-20 to be free from
defects in material or workmanship under normal use
and service. The Kasco Marine, Inc. obligation under

brackish water will freeze somewhere in between.
Setting the thermostat a couple degrees below the
freezing point can minimize unneeded operation
time.
• Daily observation is required for all de-icing
installations. Adjust operating times based on
when you can observe the operation. This will help
you check the de-icer is operating properly.
• Several factors can increase freeze rate. Such
as, wind, snow, and colder temperatures. When
picking operation times, set the de-icer to operate
more when conditions promote quicker freezing.
• Your settings will likely require some ne tuning.
Remember to observe your de-icer installation
and be prepared to adjust your settings of the
C-20. Thermostat tolerance may also need to
be adjusted for. The actual ON/OFF point of the
thermostat may be -/+ 2.7°F of the actual ambient
temperature.
• Operating with fewer, longer cycles will provide
the most efcient de-icing. The following is an
example of setting the timer over a 24 hour period.
The 4 ON cycles below allow for more operating
time during dark hours and less during daytime
hours. (This is suggested due to increased freezing
rate at night).
Cycle Time Length
ON 7:00 a.m. - 9:00 a.m. 2 hr
OFF 9:00 a.m. - 1:00 p.m. 4 hr
ON 1:00 p.m. - 3:00 p.m. 2 hr
OFF 3:00 p.m. - 7:00 p.m. 4 hr
ON 7:00 p.m. - 10:00 p.m. 3 hr
OFF 10:00 p.m. - 12:00 a.m. 2 hr
ON 12:00 a.m. - 5:00 a.m. 5 hr
OFF 5:00 a.m. - 7:00 a.m. 2 hr
This sample would allow the de-icer to operate a
maximum of 12 hours in a 24 hour period. During
the ON cycles, the thermostat would determine if
the de-icer operates based on its dial setting. Actual
settings and durations of run time will depend on your
installation requirements and regional demands for
de-icing.
• To bypass the timer and operate only on
temperature, set the timer ON/AUTO switch to
ON. This will turn the timer output on indenitely #824401 Rev. 02/12/15
