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
storage bin area. Order the necessary parts from your

local ice maker dealer.

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.

2. The ideal installation has a standpipe (IV4”
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.

Drain pump

1. When drain connection below the level of the unit

is not available a drain pump may be used to lift the
water to an available drain.

2. Install drain pump on floor behind ice maker with
discharge tube to the rear. Run bin drain directly
into pump as shown in Figure 5A.

Installation Instructions

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.

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

• Compressor runs

• Condenser fan runs

• Water pump runs (circulates water)

• 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

• 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

• 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.

WHEN THE STORAGE BIN IS FILLED,

BIN THERMOSTAT OPENS.

• Cutter grid remains on

•

Things to

• 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.

If installed above 2,000 feet altitude, see page 2 for

thermostat adjustments.

remember

• Water enters only during the defrost cycle. Therefore
the first cycle will be completed without water in the
system.

Installation Instructions

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 (-i-10° to

-3° 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 -i- 2°F.

DANGER:
ELECTRIC SHOCK HAZARD disconnect power
before servicing unit. Maximum fuse size: 15

amps.
