BEFORE OPERATING THE ICE MAKER
It is your responsibility to make sure that the ice
maker: .
* has oeen installed where it is protected from
the elements,
.
* is located so that the front is not blocked to
restrict incoming or discharge air flow.
* is properly leveled.
0 is located in a well ventilated area with tem-
peratures above 55°F (13°C) and below 110°F
(43°C). Best results are obtained at temperatures
between 70°F (21°C) and 90°F (32°C).

drain.
is properly connected to electricity. A 115 Volt,
60 Hz.. 15 amp fused electrical supply is required.
NOTE: Time delay fuse or circuit breaker is
recommended.

is properly maintained.
ICE MAKER OPERATION
How it makes ice:
4. Fresh water enters the machine for the next ice
making cycle.
1. bv;iter is constantly circuiated over a freezing
plate. As the water freezes into ice the minerals in
the water are rejec:.ed. This produces a clear sheet
of ice with a low mineral content. El@@
5. Cubes fall into the storage bin. When the bin is
full the ice maker shuts off automatically and re-
starts when more ice is needed.
2 When the desired thickness is reached, the ice
sheet is released and slides on to a cutter grid. The
grid divides the sheet into individual cubes.
3 The water containing the rejected minerals is
tlrained after each freezing cycle.

To 3perate the Ice Maker:
1 Select ice thickness (Figure 1). The ice maker
has been pre-set to produce ice approximateiy ‘;”
thick, while operating in a room ambient of
70’F (21°C).
Operation in different ambient temperatures may
renuire readjusting the control toward “THICK”
01. “THIN.”

Best operation will be obtained with ice l/2” to
5,‘8” thick.
If operating in a warm room ambient (above 90°F
[32”C] ) DO NOT set control to maximum thick-
ness or the unit may malfunction.
2. To start the normal ice making cycle, turn service
or cycle switch to “ON.”
3. To stop ice maker operation, turn service or
cycle switch to “OFF.”
4. The “CLEAN” setting is used whenever solutions
are circulated through the ice maker for cleaning.
Only the water pump operates at this setting.
GENERAL CARE AND CLEANING
Periodically inspect and clean the ice maker to
keep it operating at peak efficiency and to prevent
premature failure of system components.
1. Disconnect electrical power supply to the
machine or place the service switch in the “OFF”
position. The condenser fan should not operate
while removing dirt from the condenser.
Both the ice making system and the air cooled
condenser need to be cleaned regularly.
Cleaning exterior surfaces:
2. Remove the two screws from the bottom of the
grilled front panel.
Waslr the exterior enamel surfaces and gaskets CAUTION: S&itch must be in “OFF” position to

4. Choose the color you want to show and carefully
slide the panels back into the door, being careful
not to scratch the panel as it’s inserted.
5. Replace the handle and screws.
1. Ooen the bin door. Remove the two screws on
top cjf the door, which hold the handle.
2. Remove the handle
Note: A brushed chrome door panel is available
that you can order from your dealer as part No.
755340.
3; C~reiully slide the panels out. You will find two
pane Is with four colors. You can also have a decorative wood front to
match existing cabinets. The panel should be l/4”
(6 mm) thick and 17” x 13-3/16” (433 mm x
335 mm). Remove the metal panels and break off
the ribs on the door insulation to allow for wood
thickness.
FILTERING AND TREATING WATER
In n‘ost areas it will be beneficial to filter or treat
th; \tvater being supplied to the ice machine. It can
Improve the reliability of the machine, reduce
vvatrr system maintenance and produce the best
quaicti/ of ice.
The installation of a polyphosphate feeder will
generally reduce scale build-up and the ice machine
Lvirl -equire less frequent cleaning.
Municipal water systems are generally treated with
chlorine to maintain a safe potable water supply.
Activated carbon filters will sufficiently remove
the residual chlorine from the water to reduce
surface staining of stainless steel materials in the
ice machine.
For information on filtering and treating the water,
see the dealer from whom you purchased your ice
maker or your WHIRLPOOL Franchised TECH-
CARE@ service company.
TO SHUT DOWN THE ICE MAKER
1. imi;rn ice maker to “OFF.”
2. Remove all ice frorr storage bin.
3. Shut off the water supply.

6. Replace front grille .jnd screws.
7. Remove water from drain lines and drain water
pan if the unit will be subjected to freezing tem-
peratures during shut down.
8. Before using again, clean and sanitize the ice
maker and storage bin.
Oiling:
All components of the ice maker are permanently
lubricated at the factory. They should not require
any additional oiling throughout the normal life of

IF YOU NEED SERVICE OR ASSISTANCE,
WE SUGGEST YOU FOLLOW THESE FOUR STEPS:
I = Before calling for assistance. . .
Performance probler
yo:~ can find and fix
1. :Jnit does not run
ns often result from little things
yourself.
* Service or Cyr le switch rnust be in “ON”
position.
D Check to see that power cord is plugged in.
0 Check for blown fuse or tripped circuit breaker
in electrical supply to machine.
* Room temperature must be above 55°F. (13°C).
Otherwise, bin thermostat may sense cold
room temperature and shu- off even though
bin is not full of ice. Also, unit may not re-
start once it does shut off.
2. Unit runs but produces no ice:
0 Service or Cycle switch must be in “ON”
position.
* Check water supply to make sure it is open.
l If ice machine is operated at an elevation of
2,000 feet or more above sea level, both the
bin thermostat and the ice thickness thermostat
need to be recalibrated. See Installation
Instructions.
3. 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.
0 Dirt or lint may be blocking the air flow
through the finned condenser. Condenser
needs to be cleaned.
l Check to see if the unit has a scale build-up in
water and freezing system. Clean, if necessary.
4. Grid is not cutting ice sheets:
l Check the grid harness plug to make sure the
connection is secure.
5. Taste in ice cubes:
l There may be an unusually high mineral
content in water supply. Water may need to
be filtered or treated.
0 Do not store any foods in the Ice bin.
l Packaging material not all removed.
