Installation of the ice maker requires a cold

•

water supply inlet of

1

“ (6mm) OD soft copper

4

tubing with a shut-off valve and either a
gravity-drain system or condensate pump to
carry the water to an existing drain.

CSW45

Use two or more people to move and install ice
maker.

Failure to do so can result in back or other injury.

Removing packaging materials

IMPORTANT: Do not remove any permanent

instruction labels inside your ice maker or the Tech
Sheet that is fastened behind the lower access
panel.

• Remove tape and any labels from your ice

maker before using (except the model and serial
number label).

To remove any remaining tape or glue, rub the area
briskly with your thumb. Tape or glue residue can
also be easily removed by rubbing a small amount of
liquid dish soap over the adhesive with your fingers.
Wipe with warm water and dry.

•

Do not use sharp instruments, rubbing alcohol,
flammable fluids, or abrasive cleaners to remove
tape or glue. These products can damage the
surface of your ice maker. For more information,
see the “Important Safety Instructions” section.

Choose a well ventilated area with

•

temperatures above 55°F (13°C) and below
100°F (38°C). Best results are obtained
between 70°F (21°C) and 90°F (32°C). This unit
MUST be installed in an area protected from the
elements, such as wind, rain, water spray, or
drip.

When installing the ice maker under a counter,

•

follow the recommended opening dimensions
shown. Do not place electrical or plumbing
fixtures in the clear zone as indicated by the
gray shaded area.

NOTE: Do not kink or pinch the power supply cord
between the ice maker and cabinet.

Electrical & Leveling

Electrical Shock Hazard

Plug into a grounded 3
prong outlet.

Failure to follow these
instructions can result in
death, fire, or electrical
shock.

Do not use an extension
cord.

Do not use an adapter.

Do not remove ground
prong.

Before you move your ice maker into its final
location, it is important to make sure you have the
proper electrical connection:

A 115 Volt, 60 Hz., AC only 15 ampere electrical
supply, properly grounded in accordance with the
National Electrical Code and local codes and
ordinances, is required.

It is recommended that a separate circuit, serving
only your ice maker, be provided. Use a receptacle
which cannot be turned off by a switch or pull chain.

Recommended Grounding Method

For your personal safety, this appliance must be
grounded. This appliance is equipped with a power
supply cord having a 3 prong grounding plug. To
minimize possible shock hazard, the cord must be
plugged into a mating, 3 prong, grounding-type wall
receptacle, grounded in accordance with the
National Electrical Code and local codes and
ordinances. If a mating wall receptacle is not
available, it is the personal responsibility of the
customer to have a properly grounded, 3 prong wall
receptacle installed by a qualified electrician.

Leveling the Ice Maker

It is important for the ice maker to be level in order to
work properly. Depending upon where you install the
ice maker, you may need to make several
adjustments to level it.

To Adjust The Rear Wheel Height

CSW45

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.

1. Using a

1

“ socket wrench, remove the seven

4

screws from the rear access panel and carefully pull
the panel away from the drain hose.

2. Using a

3

“ or adjustable wrench, remove the

8

screw that holds the rear wheel.

NOTE: Pushing up against the top back of the ice
maker takes some of the weight off of the wheels.
This makes it easier to remove the screws.

2. Push up on the top front of the ice maker, and
then locate the leveling screws that are on the
bottom front of the product.

3. Using an adjustable wrench, change the height of
the legs as follows:

Turn the leveling leg to the right to lower that

•

side of the ice maker.

Turn the leveling leg to the left to raise that side

•

of the ice maker.

NOTE: The ice maker should not wobble. Use shims
to add stability when needed.

3. Move the rear wheel and screw to a new position
as needed for your cabinet opening height. Tighten
the screw completely.

4. Repeat Steps 3 and 4 to change the position of
the wheel on the other side.

5. Replace the rear panel and screws. Be sure that
the drain tube is positioned in the opening provided.

6. Use the front leveling legs to make sure the
product is level.

To adjust the front leveling legs

Your ice maker has two adjustable leveling legs to
help you steady the product and make sure it is
level.

SUGGESTION: It is easier to adjust the leveling legs
if you have another person to assist you.

1. Place a carpenter’s level on top of the product to
see if the ice maker is level from front to back and
side to side.

4. Use a carpenter’s level to re-check the ice maker
to see that it is even from front to back and side to
side. If the ice maker is not level, repeat Steps2&3.
If the ice maker is level, go to the “Connecting the
Ice Maker to a Water Source” section.

Freestanding Installation

If you are not installing your ice maker under a
countertop, you will probably not need to adjust the
rear wheel height. Follow the steps outlined in “To
adjust the front leveling legs” earlier in this section.

NOTE: The ice maker should not wobble. Use shims
to add stability when needed.

Connecting the Ice Maker to a Water Source

Read all directions carefully before you begin.

IMPORTANT:

All installations must be in accordance with local

•

plumbing codes requirements.

Use copper tubing and check for leaks.

•

Install copper tubing only in areas where

•

temperatures will remain above freezing.

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.

Slip compression sleeve and compression nut

•

on copper tubing as shown. Insert end of tubing
into outlet end squarely as far as it will go.
Screw compression nut onto outlet end with
adjustable wrench. Do not over tighten.

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.

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

1

"to

2

1

" vertical cold water pipe near the

1

4

ice maker.

NOTE: Horizontal pipe will work, but the following
procedure must be followed: Drill on the top side of
the pipe, not the bottom. This will help keep water
away from the drill. This also keeps normal sediment
from collecting in the valve.

4. Using a grounded drill, drill a

1

" (6 mm) hole in the

4

cold water pipe you have selected.

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.

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.

REAR VIEW

2. Lower Water Line Access Hole

5. Fasten shut-off valve to cold water pipe with pipe
clamp. Be sure outlet end is solidly in the

1

-inch

4

drilled hole in the water pipe and that washer is
under the pipe clamp. Do not use a piercing-type or

3

" saddle-type valve which reduces water flow and

16

clogs more easily.

6. Now you are ready to connect the copper tubing.

1

Use

" (6mm) OD soft copper tubing for the cold

4

water supply.

•

Measure from the connection at the front of the
ice maker to the cold water pipe. Add 3 feet to
ensure that you have the proper length. This is
the length of

1

" (6mm) OD soft copper tubing

4

you need for the job. Be sure both ends of the
copper tubing are cut square.

12. Turn shut-off valve on. Check for leaks.

Tighten any connections (including connections at
the valve) or nuts that leak. The ice maker is
equipped with a built-in water strainer. If local water
conditions require periodic cleaning or a well is your
source of water supply, a second water strainer
should be installed. Obtain a water strainer from your
nearest appliance dealer and install it at either tube
connection.

Using The Ice Maker

CSW45

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.

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.

3. The water containing the rejected minerals is
drained after each freezing cycle.

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.

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

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.

1. To start the normal ice making cycle, select ON.

2. To stop ice maker operation, select OFF.

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.

Clean the ice and water system periodically to
remove mineral scale buildup. Frequency of cleaning
depends on water hardness. With hard water (15 to
20 grains/gal. [4 to 5 grains/liter]), cleaning may be
required as frequently as every 6 months.

Cleaning Exterior Surfaces

Wash the exterior enamel surfaces and gaskets with
warm water and mild soap or detergent. Wipe and
dry. Regular use of a good household appliance
cleaner and wax will help protect the finish.

5. 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.

6. 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.

NOTE: Severe scale buildup may require repeated
cleaning with a fresh quantity of cleaning solution.

7. Push the selector switch to ON to resume ice
production.

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. Pour 16 ounces of
Scotsman Clear 1 scale remover into the water pan.
Fill the bottle twice with tap water and pour it into the
water pan.

n Is the control set to ON?

Be sure that the control is set to ON.

n Is the power cord plugged in?

Firmly plug the cord into a live outlet with proper
voltage.

n Has a household fuse or circuit breaker

tripped?

Replace the fuse or reset the circuit.

n Is the room temperature cooler than normal?

Room temperature must be above 55°F (13°C).

Otherwise, bin thermostat may sense cold room
temperature and shut off even though bin is not full
of ice. Also, unit may not restart once it does shut off.

Unit runs but produces no ice

If there is white scale buildup in the ice maker’s
water or freezing system, you should clean the ice
maker. See the “Cleaning the Ice Maker System”
and the “Cleaning the Interior Components” sections.

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

CSW45

The compressor, fan motor and water pump are all
operating and stay in a Freeze cycle until the
evaporator thermistor reaches 6.5

o

F. 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 52

o

F. 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 35
when the thermistor’s temperature increases to 41

o

F. It will restart

o

F.

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.

Water Slide

The water slide is mounted to the front of the
evaporator and diverts water to the reservoir. It is
connected to the evaporator by two screws. Remove
the cutter grid first to get access to it.

Reservoir

The reservoir is located below the evaporator, and is
mounted to the bin liner with two screws.

Water Pump

The water pump is located below the evaporator. It is
mounted to the bin liner with three screws. It also
has a quick-connect electrical plug.

Evaporator Thermistor

This thermistor is a set of two red wires that connect
to the control box. There is a molded portion in one
of the wires with a clip on it. That portion clips onto
the part of the suction line under the middle of the
evaporator that runs front to back.
