into outlet end squarely as far as it will go.
Screw compression nut onto outlet end with
adjustable wrench. Do not over tighten.
7. Place the free end of the tubing into a container or
sink, and turn on main water supply and flush out
tubing until water is clear. Turn off shut-off valve on
the water pipe.
• Install copper tubing only in areas where
temperatures will remain above freezing.
Before purchasing, make sure a saddle-type valve
complies with your local plumbing codes. Do not
use a piercing-type or 3/16” saddle valve which
reduces water flow and clogs more easily.
NOTE: Always drain the water line before making
the final connection to the inlet of the water valve to
prevent possible water valve malfunction.
8. Remove the two screws in the lower access panel
and the two screws in the base grille area of the front
panel support. Pull forward to remove the lower
access panel.
Connecting the water line:
1. Unplug ice maker or disconnect power.
2. Turn off main water supply. Turn on nearest
faucet long enough to clear line of water.
3. Find a 12" to 1 14" vertical cold water pipe near the
ice maker.
9. Position the tubing so it can enter one of the two
access holes located at the right-hand rear of the
cabinet as shown. The tubing should extend beyond
the cabinet front when the cabinet is pushed back
into position. Move the ice machine into position.
NOTE: Horizontal pipe will work, but the following

Using The Ice Maker
3. The water containing the rejected minerals is
drained after each freezing cycle.
Understanding How Your Ice Maker Works
When you first start your ice maker, the water pan
will fill and the system will rinse itself before starting
to make ice. The rinsing process takes about five
minutes.
Under normal operating conditions, the ice maker will
cycle at preset temperatures. The ice level sensor
located in the ice storage bin will monitor the ice
levels.
4. Fresh water enters the machine for the next ice
making cycle.
5. Cubes fall into the storage bin. When the bin is
full, the ice maker shuts off automatically and
restarts when more ice is needed. The ice bin is not
refrigerated and some melting will occur. The
amount of melting varies with room temperature.
IMPORTANT
• If the water supply to the ice maker is turned off,
be sure to set the ice maker control to OFF.
• The ice maker is designed to make clear ice
from the majority of water sources on a daily
basis. If your results are unsatisfactory, your
water may need to be filtered or treated.
Making Ice
1. Water is constantly circulated over a freezing
plate. As the water freezes into ice, the minerals in
the water are rejected. This produces a clear sheet
of ice with a low mineral content.
NOTE: As the room and water temperatures vary, so
will the amount of ice produced and stored. This
means that higher operating temperatures result in
reduced ice production.
Setting the Controls
1. To start the normal ice making cycle, select ON.
2. To stop ice maker operation, select OFF.
2. When the desired thickness is reached, the ice
sheet is released and slides onto a cutter grid. The
grid divides the sheet into individual cubes.
NOTE: The CLEAN setting is used whenever
solutions are circulated through the ice maker for
cleaning. Only the water pump and compressor
operate at this setting. See the “Cleaning the Ice
Maker System” section.
July 1999
Page 11
CSW45
Caring For Your Ice Maker
Periodically inspect and clean the ice maker to keep
it operating at peak efficiency and to prevent
premature failure of system components.
Both the ice making system and the air cooled
condenser need to be cleaned regularly.
The minerals rejected from the circulating water
during the freezing cycle will eventually form a hard
scaly deposit in the water system which prevents a
rapid release of the ice from the freezing plate.
6. Push the selector switch to CLEAN. (See the
“Setting the Controls” section.) The light will turn on,
indicating that the cleaning cycle is in process. When
the indicator light turns off (approximately 45
minutes), the cleaning cycle is complete. During the
cleaning cycle, the system will both clean and rinse
itself.
7. After the cleaning cycle is complete, remove the
drain cap from the water pan to see if any cleaning
solution is left in the water pan. If cleaning solution
drains from the water pan, you should run the clean
cycle again.
Clean the ice and water system periodically to
remove mineral scale buildup. Frequency of cleaning
depends on water hardness. With hard water (15 to
NOTE: Severe scale buildup may require repeated
20 grains/gal. [4 to 5 grains/liter]), cleaning may be

Do not use abrasive cleaners on enamel surfaces as
they may scratch the finish.
Cleaning the Ice Maker System
1. Push the selector switch to OFF.
2. Wait 5 to 10 minutes for the ice to fall into the
storage bin. Remove all ice from the storage bin.
3. Unscrew the drain cap from the bottom of the
water pan located inside the storage bin as shown.
Allow the water to drain completely.
4. Replace the drain cap. into the water pan. Fill the
bottle twice with tap water and pour it into the water

Cleaning the Condenser
4. Remove dirt and lint from the condenser fins and
the unit compartment with a brush attachment on a
vacuum cleaner.
A dirty or clogged condenser:
• Prevents proper airflow.
• Reduces ice making capacity.
• Causes higher than recommended operating
temperatures which may lead to component
failure.
Electrical Shock Hazard
Failure to follow these
instructions can result in
death, fire, or electrical
shock.
Disconnect power before
servicing.
Replace all panels before
operating.

Electrical Sequence
The CSW45’s operation is controlled by an electronic
board. This board takes in data from two thermistors:
The Ice Bin Thermistor and the Evaporator
Thermistor. The two resistances the thermistors
supply, along with the position of the control switch,
determine the cycles of the ice machine.
Start Up
The inlet water valve opens for about two minutes to
fill the reservoir.
The water pump starts and stays on for about a
minute, then shuts off.
Then the inlet water valve opens again for two
minutes. After it closes, the compressor, pump and
fan motor start.
Freeze
The compressor, fan motor and water pump are all
operating and stay in a Freeze cycle until the
evaporator thermistor reaches 6.5oF. That signals
the control board to place the unit into a harvest
cycle.
Harvest
The compressor and hot gas valve are both powered
during the harvest cycle. The fan and pump are OFF.
The machine stays in the harvest cycle until the
evaporator thermistor senses 52oF. If the bin is not
full, the unit goes into another freeze cycle.
Bin Full
The unit will shut down when the ice level sensor
senses a temperature of less than 35oF. It will restart
when the thermistor’s temperature increases to 41oF.
Clean
The Clean Cycle lasts about 47 minutes. During the
first minute all motors and valves will be switched on
in sequence for 5 seconds each. This includes the
inlet water valve, condenser fan, hot gas solenoid
valve, water spray pump and the compressor. This
early portion of the Clean Cycle doubles as a
diagnostic cycle. The last 46 minutes of the clean the
compressor, water spray pump and hot gas valve will
be on.
