Changing the bin door
panel
The storage bin door is designed to accept an optional
decorative wood panel of your choice.
The wood panel should be no more than l/4 inch (6 mm)
thick. Cut it to the same size as the production metal
panel. See Figure 1.
To change the panel:
1. Open the bin door.
2. Remove the two screws on top of the door which
hold the handle.
3. Remove the handle and pocket.
4. Slide the metal panel out.
5. Break off the ribs on the door insulation to allow for
the wood thickness. See Figure 2.
6. Slide the wood panel into the door frame.
7. Replace handle and screws.

Thermostat calibrations
If ice maker is installed above two thousand feet of
altitude, the bin and evaporator thermostats must be
adjusted to a warmer setting. Disconnect electricity,
remove thermostat and follow the directions for turn-
ing the altitude adjustment screw as shown in the label
on each thermostat.
Shipboard operation
When this ice cube maker is installed aboard a ship,
it will be necessary to purchase and install a water
deflector. This deflector hangs between the lower edge
of the evaporator and the cutter grid. It keeps the water
flowing over the evaporator from spilling into the
storaae bin area. Order the necessary parts from your
local Tee maker dealer.

Utilities
WATER ELECTRICITY DRAIN
OBSERVE LOCAL CODES
Each installation is unique but will require:
1. A cold water inlet of l/4” OD soft copper tubing and
a shut-off valve.
2. Either a gravity drain system or a sump pump to lift
the water to an existing drain.
3. An electrical branch circuit of 115 Volt, 60 Hz. 1
phase, with a 15 Amp delayed action fuse or circuit
breaker.

2. Area should be well ventilated with temperature
above 55OF and below 1lOOF. Best results are ob-
tained between 7OOF and 9OOF.
3. Provision for electricity, water and drain connections
should be determined.
4. The unit may be closed in on the top and three sides,
but the front MUST BE unobstructed for air circula-
tion and proper operation. Installation should be
such that the cabinet can be moved forward for ser-
vicing, if necessary.
Level unit
1. After placing unit in position, check to make certain
the unit is level side to side and front to back.
2. Accurate leveling is essential for proper operation.
3. Unit should be shimmed so that it is solid as well
as level. The shims should be of hard permanent
type material such as masonite.
4. If required by sanitation code, seal the cabinet to the
floor with an approved caulking compound.
For the plumber
Connect to water
(0 bserve local codes)
1. Use l/4” OD soft copper tubing for the cold water
supply.
2. Provide a convenient manual shut-off valve in the
water line.
3. Position the tubing so it can enter the access hole
located in the right-hand rear of the cabinet. The tub-
ing shoud extend beyond the cabinet front when the
cabinet is pushed back into position. See Figure 5.
NOTE:
Always purge the water line before making the final con-
nection to the inlet of the water valve to prevent possi-
ble water valve malfunction.
After the cabinet is in place, bend the tubing to meet
the connection at the water valve. The garden hose
threaded compression fitting is found in the parts bag.
This joint provides a convenient disconnect for service.
Be sure the tubing is clear of compressor, to prevent
rattle.
1. Place unit so the front side will be completely
unobstructed to provide proper air flow.

(observe local codes)
1. The unit is provided with a gravity drain.
2. The ideal installation has a standpipe (1%”
minimum) installed directly below the outlet of the
drain tube. Refer to figure 5 for the proper location
of the standpipe.
3. It may be desirable to insulate drain line thoroughly
up to drain inlet to minimize condensation on drain
tube.
Condensate pump
1. When drain connection below the level of the unit is
not available a condensate pump may be used to lift
the water to an available drain.
2. Install condensate pump on floor behind ice maker with
discharge tube to the rear. Run bin drain directly into
pump as shown in Figure 5A.
3. Run power cord thru hole into unit compartment (See
Figure 5A)
4. Remove lower grille assembly. (See Figure 58)

For the electrician
Electrical requirements
A 115 Volt, 60 Hz, AC only, 15 Amp fused electrical
supply is required (time delay fuse or circuit breaker
is recommended). It is recommended that a separate
circuit, serving only this appliance, be provided. DO
NOT use an extension cord.
ELECTRICAL GROUND IS REQUIRED ON THIS
APPLIANCE.
Recommended
grounding methods
DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE
THE POWER SUPPLY CORD GROUND PRONG.
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 and obligation of the customer to have
a properly grounded 3-prong wall receptacle installed
by a qualified electrician. See Figure 6.
FIGURE 6
Alternate
grounding method
DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE
THE POWER SUPPLY CORD GROUND PRONG.
If changing and properly grounding the wall receptacle
is impossible and where local codes permit (consult
your electrical inspector), a temporary adapter may be
plugged into the existing 2-prong wall receptacle to
mate with the 3-prong power supply cord. See Figure
7. THIS, HOWEVER, IS NOT RECOMMENDED.
If this is done, you must connect the grounding eyelet
on the adapter to the wall receptacle cover plate screw
and from this same screw, you must connect a separate
copper ground wire (No. 4 minimum) to a grounded cold
water pipe’. See Figure 7. Do not ground to a gas supp-
ly pipe. Do not connect to electrical supply until ap-
pliance is permanently grounded.
*Cold water pipe must have metal continuity to elec-
trical ground and not be interrupted by plastic, rubber
or other electrically insulating connectors (including
water meter or pump) without adding a jumper wire at
these connections

How it works
l Compressor runs
l Condenser fan runs
l Water pump runs (circulates water)
l Cutter grid is warm to touch
WHEN THE DESIRED ICE SLAB
THICKNESS IS REACHED, THE
HARVEST CYCLE BEGINS AND THE
FOLLOWING HAPPENS:
Evaporator thermostat is satisfied
Compressor keeps running
Condenser fan stops or turns very slowly
Water pump stops
Hot gas solenoid opens
Water inlet valve opens
Excess water is flushed out of the drain pan
Cutter grid is warm to the touch
NOTE: Normal harvest cycle takes 60 to 120
seconds.
MACHINE RESUMES FREEZING
AFTER SLAB IS RELEASED FROM
EVAPORATOR AND THE CUTTING
PROCESS BEGINS.
As the room and water temperatures vary, so will the
amount of ice produced. This means that higher
operating temperatures will result in reduced ice
production.
The unit will shut off when ice in the storage bin
touches the bin thermostat well and will automatical-
ly cycle to keep the bin full.
The storage bin is not refrigerated and some meltage
will occur. This, too, varies with the room
temperature.
The unit needs good air circulation to perform effi-
ciently. Keep the front grill and the condenser clean.
The water system, including filter screen in the water
inlet solenoid valve, needs to be cleaned periodically
for good circulation. Instructions are located on the
inner door panel.
Operating instructions
For complete operating information, refer to the Use
and Care Guide.
Before starting, wash out interior of cabinet with a
Baking Soda solution (2 tablespoons soda to a quart
of warm water). Rinse thoroughly.
Make certain the water is turned on.
Turn switch to the “ON” position.
IMPORTANT:
Allow unit to run for 3 hours before expecting
ice and for 24 hours before trying to set the
thickness control.
installed above 2,000 feet altitude, see page 2 for
thermostat adjustments.
WHEN THE STORAGE BIN IS FILLED,
BIN THERMOSTAT OPENS.
l Cutter grid remains on
Things to
remember
l Water enters only during the defrost cycle. Therefore
the first cycle will be completed without water in the
system.

Unit wiring diagram
This model operates at 115 volts except for the cutter
grid circuit which operates at 8.5 volts at 1 amp.
The compressor runs at all times except when the bin
thermostat becomes satisfied and opens up. This de-
energizes the system except for the transformer and
cutter grid.
Under normal operating conditions, when the
evaporator reaches the preset temperature ( + 100 to
-30 F, depending on thickness of ice) the evaporator
thermostat opens, terminating operation of the fan
motor and pump motor. The hot gas solenoid and the
water valve solenoid are energized at this time and re-
main so until the evaporator reaches 38 + 2OF.
