Before you plug it in
IMPORTANT
Before using your ice maker, you are responsible
for making sure that it
l has been installed where it is protected from
the elements.
l is located so that the front is not blocked to
restrict incoming or discharge airflow.
l is properly leveled.
. is located in a well ventilated area with tempera-
tures above 55°F (13°C) and below 110°F (43°C).
Best results are obtained at temperatures be-
tween 70°F (21 “C) and 90°F (32°C).
l is properly connected to a water supply
and drain.
l is properly connected to electricity. A 115 Volt,
60 Hz., AC only, 15 or 20 ampere electrical supply
circuit, properly grounded in accordance with
the National Electrical Code and local codes
and ordinances, is required. NOTE : A time delay
fuse or circuit breaker is recommended.
l is not operated by anyone unable to use it
properly.
l is used only for the job it was designed to
perform.
l is properly maintained.
Using your ice maker
How the ice maker works
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.
2. When the desired thickness is reached, the ice
sheet ISreleased and slides onto a cutter grid.
The grid divides the sheet into individual cubes.

3. The water containing the rejected minerals is
drained after each freezing cycle.
4. Fresh water enters the machine for the next
freezing 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.
Setting the controls

THIN THICK OFF - - CLEAN
ICE CYCLE
1. Select an ice thickness. The ice maker has been
preset to produce ice approximately l/z” thick
while operating in a room temperature of 70°F
(21°C).
Operation in different room temperatures may
require readjusting the Ice Thickness Control
Knob toward “THICK” or “THIN.”
Best operation will be obtained with ice I/Z”to 5/~”
thick.
If operating in a warm room temperature
(above 90°F (32°C)) DO NOT set Ice Thickness
Control Knob to maximum thickness. Doing so
could cause the unit to malfunction.
2. To start the normal freezing cycle, turn the Cycle
Control Knob to “ON.”
3. To stop ice maker operation, turn the Cycle
Control Knob to “OFF.”
The “CLEAN” setting is used whenever solutions
are circulated through the ice maker for
cleaning. Only the water pump operates at this
setting.

Changing the bin door panel
You can make a decorative wood front to match
existing cabinets.
To change the bin door panel:
1. Open the storage bin door. Remove the two
screws holding the handle to the door frame.
2. Loosen the screws in both side trim pieces.
3. Remove the handle.

4. Carefully slide the panel out and break off the
ribs on the door insulation to allow room for the
wood panel’s thickness.
5. Make the wood panel %” (6 mm) thick and
17” x 13W (433 mm x 335 mm).
6. Replace the handle and tighten the screws in
both side trim pieces. Replace the handle
screws and tighten.
Changing the lower accesspanel
Electrical Shock Hazard
Do not operate the ice maker with the
lower caccess panel or control panel
removed. Electrical shock or personal
injury could result.
1. Remove the two screws in the lower grille area
and the one screw from the center of the front
panel support. (Open bin door slightly for better
access to screw.) Pull forward and down to
remove the lower access panel.
3. Carefully slide the panel out.

Cleaning and 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 systems periodically to
remove mineral scale buildup. Frequency of
cleaning depends on water hardness. With water
that contains few impurities, cleaning may not be
required for several years. With hard water (15 to
20 grains/gallon), cleaning may be required as
frequently as every six months.
A dirty or clogged condenser:
l prevents proper airflow.
l reduces ice making capacity.
l causes higher than recommended operating
temperatures which may lead to component
failure.
Cleaning exterior surfaces
Wash the exterior painted surfaces and gaskets
with warm water and mild soap or detergent.
Rinse and dry. Regular use of a good household
appliance cleaner and wax will help protect the
finish.
Do not use harsh or abrasive cleaners on the
enamel surfaces. They may scratch the finish.
Cleaning the condenser
Personal Injury and Product Damage Hazard
l Be sure the ice maker is OFF and disconnected from the main
power supply. Condenser fan rotation, sharp condenser fins,
and hot tubing could cause personal injury.
l Condenser fins can bend easily. Use care when vacuuming
the condenser to keep from bending fins. Product damage
could result.
1. Turn the Cycle Control Knob to the “OFF” position. I III I II
Then disconnect electrical supply to the i&e maker.

2. Remove the two screws in the lower grille area
and the one screw from the center of the front
panel support. (Open bin door slightly for better
access to screw.)
3. Pull forward and down to remove the lower
access panel.
4. Remove dirt and lint from the condenser fins
and the unit compartment with a brush attach-
ment connected to a vacuum cleaner.
5. Replace the grilled front panel and screws.
6. Plug ice maker in and place the Cycle Control
Knob in the “ON” position.

Cleaning the ice maker system
Personal Injury Hazard
Most ice machine cleaners are citric or phosphoric acid which
con cause irritation, even after dilution. In case of contact with
eyes, flush eyes thoroughly with fresh water and contact a
physician immediately. In case of contact with skin, rinse well
with water. If swullowed, give large amounts of water and
contact a physician immediately. Do not induce vomiting.

6. Pour 2 quarts (2 L) of hot water into the water
pan and turn the cycle control to “CLEAN.”
This step warms up the system and allows the
cleaning solution to be more effective. Allow
to circulate 5 minutes. Turn switch to “OFF” and
drain. Prepare the cleaning solution by
thoroughly mixing 6 oz. (170 g) of powdered
citric acid or phosphoric acid into 2 quarts
(2 L) of hot water. Commercial ice machine
cleaners are also available in liquid form and
should be mixed according to instructions on
the label.
7. Pour cleaning solution into water pan and turn
switch to “CLEAN.” If solution foams while
pouring, stop until foaming subsides, then add
balance of solution. Allow solution to circulate
until scale has dissolved. The circulating
solution may not contact scale on the side
flanges of, the freezing plate. To remove this
scale, wear rubber gloves and use a stainless
steel sponge or pad dipped in cleaning
solution to scrub the side flanges until scale is
removed. Generally scale will be dissolved in
15 tc 30 minutes. Severe scale formation may
require repeating the cleaning process with a
fresh quantity of solution if the scale has not
dissolved after 30 minutes.
8. Turn switch to “OFF” and drain.
9. Follow cleaning with two fresh water rinses,
circulating each rinse for 5 minutes, and drain.
10. This completes the “in place” cleaning and
sanitizing of the water system and freezing
plate Other interior components must also be
cleaned and sanitized.

6. Remove the water distributor from the freezing
plate. It is held in place by rubber end caps.
Remove the inlet hose and clean all water
distributor holes and the small orifice in the inlet
side of the distributor. When replacing the
distributor, make sure the end caps are located
in the evaporator flange detents and that the
water distributor holes face down.
7. Wash the interior components (ice retainer
baffle, cutter grid, water pan, inlet hose, and
water distributor) and the storage bin, door
gasket, and ice scoop with mild soap or
detergent and warm water. Rinse in clean
water. The components should also be cleaned
in a solution of % oz. (8 mL) of chlorine bleach
mixed with 1 gallon (3.8 L) warm water.
DO NOT WASH PLASTIC PARTS IN THE
DISHWASHER. They cannot withstand
temperatures above 145°F (63%).
8. Replace the interior components (water dis-
tributor, inlet hose, water pan, cutter grid, and
ice retainer baffle).
9. Check the following:
l Hose from water valve is in the water pan.
l Rubber drain plug is in the water pan.
l Water distributor is seated and holes are
facing down.
l Hose is reconnected to the pump and the
water distributor.
l Hose from water pan is inserted into the
storage bin drain opening.
10. Reconnect the electrical harness, and slide
cutter grid into place. Tighten the thumb
screws.

Filtering and treating water
In some areas, it may be beneficial to filter or treat
the water being supplied to the ice machine. It
can improve the reliability of the machine, reduce
water system maintenance, and produce a better
quality of ice.
For information about filtering and treating the
water, see the dealer from whom you purchased
your ice machine.
The installation of a polyphosphate feeder will
generally reduce scale buildup, and the ice
machine will require less frequent cleaning.
Vacation and moving care

If you need service or assistance, we suggest
you follow these steps:
Before calling for service ...
Performance problems often result from little things
you can find and fix yourself, without tools of any
kind.
Unit does not run:
l Cycle Control Knob must be in the “ON” position.
l Check to see that the power cord is plugged in.
l Check for a blown fuse or tripped circuit breaker
in the electrical supply to the machine.
l Room temperatures must be above 55°F (13°C).
Otherwise, the Bin Thermostat may sense a cold
room temperature and shut off even though the
storage bin is not full of ice. Also, the unit may not
restart once it does shut off.
Unit runs but does not produce ice:
l Cycle Control Knob must be in the “ON” position.
l Check water supply to make sure it is open.
l If ice machine is operated at an elevation above
2000 feet above sea level, both the Bin Thermo-
stat and the Ice Thickness Thermostat need to be
recalibrated. See Installation Instructions.
Unit runs but produces very little ice:
l Room temperature may be extremely high (over
90°F (32°C)). In this case, it is normal for ice
production to be low.
l Dirt or lint may be blocking the airflow through
the finned condenser. Condenser needs to be
cleaned.
l Check to see if the unit has a scale buildup in the
water and/or freezing systems. Clean them, if
necessary.
Grid is not cutting ice sheets:
l Check the grid harness plug to make sure the
connection is secure.
Off taste in ice cubes:
. There may be an unusually high mineral content
in the water supply. Water may need to be
filtered or treated.
l Do not store any foods in the ice bin.
