Kasco Model C-20 Time & Temperature Unit Control
Owners Instructions
(Please read completely before installing and operating your Kasco Equipment)
CAUTION:
To ensure the safe operation and long life of your Kasco
Equipment, always take the following precautions:
•
Always
keep people and objects clear of the De-Icer pro-
peller when operating.
•
Always
disconnect
the power before servicing or remov-
ing your De-Icer.
•
Always operate your Kasco De-Icer
in the water
! Oper-
ating your De-Icer dry (on shore or dock) can cause
damage to the seals or injure operator.
•
Always
mount your C-20 on a
vertical surface
and oper-
ate only with the
cover closed
.
•
Never
lift your Kasco De-Icer or C-20 control by the
power cable. This could damage the power cable and
make your De-Icer or control unsafe to operate.
•
Kasco Marine highly recommends that all possible
pre-
cautions be taken
around open water De-Icing areas to
ensure the safety of the public, i.e., “Thin Ice” and/or
“Open Water” signs, appropriate lighting, fencing or
other safety measures as required in your area.
•
There are certain conditions under which no circulator
can prevent ice damage such as ice that moves due to
wind or current, extremely cold weather where ice forms
all the way to the bottom and in some cases where the
bottom water temperature is the same as ice (very shal-
low water). Effective operation can be somewhat re-
stricted by too little bottom clearance.
INSPECTING YOUR C-20 UNIT CONTROL:
Upon receiving your Kasco C-20 Unit Control, please un-
pack and inspect your C-20 for any possible damage that
may have happened during shipment. Any damage or short-
age should be reported to your dealer/delivery service imme-
diately to ensure prompt resolution.
INSTALLATION:
This unit
must
be mounted on a vertical surface close
enough to your power supply to allow at least a slight slack
in the power cord from the C-20. Select the screw(s) with
which to mount your C-20. You will need one for the slot
near the top of the box and you may wish to utilize the two
additional mounting holes located near the inside bottom of
the C-20 box. At this time, prior to final installation, you
may wish to do some pre-programming of the timer and
thermostat (see Programming below).
Install the De-Icer power cord through the hole in the
lower left portion of the C-20 housing and plug it into the
receptacle inside the C-20.
Important
: Your C-20 is designed to operate only one
Kasco De-Icer. For the most accurate operation, avoid plac-
ing your C-20 in direct sunlight. Complete programming
the timer and thermostat now.
PROGRAMMING:
The advance design of Kasco’s C-20 gives you both time
and temperature control of your De-icer. The C-20 is wired
in a series configuration giving you control based on both
time and temperature. Your Kasco De-Icer will only operate
when both the timer and the thermostat are activated. The
red indicator light will
only
be lit when both time and tem-
perature are activated.
You will need to program both the timer and thermostat to
complete your programming and we will address the how’s,
why, and recommendations for each separately below.
TIMER:
The timer is programmable in 30 minute incre-
ments, but do
not
program the timer in segments of less than
a one hour period at any time.
•
Setting Timer:
1. Pull out each tripper for every half hour of ON time be
tween desired hour mark on dial.
2. Turn dial clockwise
one or more revolutions until
correct time-of-day is adjacent to the timer arrow in the
center of dial.
THERMOSTAT:
The thermostat has a 6
O
F differential.
This means that the De-Icer will come
ON
at the tempera-
ture setting and will not go
OFF
until the temperature
reaches 6
O
F above the
ON
setting.
•
Setting Thermostat:
Set dial to temperature at which you wish to have
your Kasco De-Icer begin activation.
RECOMMENDATIONS:
Use the following guide lines and hints to assist in customiz-
ing your setting for local conditions.
•
De-Icers set up small localized currents the longer they
run. Fewer and longer operation cycles will prove to be
more effective than more frequent and shorter operation
cycles.
•
Fresh water freezes at 32
O
F, salt water at 28
O
F, and
brackish water will freeze somewhere in between de-
pending on the salinity level. Most people find that by
setting the thermostat a couple degrees below the freez-
ing point, they can minimize unneeded operation time
for two reasons:
A. Once activated, the thermostat stays activated until the
temperature rises the 6
O
F differential, putting the tem-
perature above the freezing point.
