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.
