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 turning 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.

FOR THE PLUMBER
CONNECT TO WATER SUMP PUMP
(observe local -codes)
1 Use 114” OD soft copper tubing for the cold water
supply.
2 Provide a convenrent manual shut-off valve In the
water line.
3 Position the tub’ rng so it can enter the access hole
located in the right-hand rear of the cabinet. The
tubing should 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
connection to the inlet of the water valve to prevent
possible 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.
CONNECT THE DRAIN
(observe local codes)
1 The unit IS provided with a gravtty drain.
2 The Ideal Installation has a standpipe (llf4”
mlnrmum) 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 dram inlet.
1 When a drain connectlon below the level of the unit
IS not avallable. a sump pump may be used to Irft
the water to an avarlable drain
2 Install sump pump on floor behind ice maker with
discharge tube to the rear. Run bin drain directly
Into sump pump as shown In the Illustration.
NOTE:
Electric connection to sump pump should be from a
circuit that remains energized continually.

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 MtHOD
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 Natlonal
Electrical Code and local codes and ordinances. If a mating
wall receptacle is not available, it is the personal responslbillty
and obligation of the customer to have a properly grounded
3-prong wall receptacle installed bv a qualified electrician

GROUNDING METHOD
DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE
THE POWER SUPPLY CORD GROUND PRONG.
If changing and properly grounding the wall recepta-
cle IS lmposslble and where local codes permit
(consult your electrlcal 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 RE-
COMMENDED.
If this IS done, you musT connect the grouncllng 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 mlnimum) to a qrounded cold water pipe’ See Flgu:e
7 Do not ground to a gas supply pipe. Do not connect to
electrical supply until appliance IS permanently grounded.
-Cold water pipe must have melal contlnulty to electrIcal
ground and not be Interrupted by plastic rubber or other
electrIcally lnsulatlng connectors (including waler meter or
pump) wlthout addlng a lumper wire at these connectlons

HOW IT
WORKS THINGS TO
REMEMBER
0 Compressor runs
0 Condenser fan runs
0 Water pump runs (circulates water)
0 Cutter grid is warm to touch
WHEN THE DESIRED ICE SLAB
THICKNESS IS REACHED, THE
HARVEST CYCLE BEGINS AND THE
FOLLOWlNG HAPPENS:
0 Evaporator thermostat IS satisfied
0 Compressor keeps running
0 Condenser fan stops or turns very slowly
0 Water pump stops
0 Hot gas solenoid opens
0 Water inlet valve opens
0 Excess water is flushed out of the dram pan
0 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 CUlTlNG
PROCESS BEGINS.
WHEN THE STORAGE BIN IS FILLED,
BIN THERMOSTAT OPENS.
0 Cutter grid remains on
0 Water enters only during the defrost cycle. There-
fore the first cycle will be completed without
water in the system.
0 As the room and water temperatures vary, so will
the amount of ice produced. This means that
higher operating temperatures will result in re-
duced ice production.
0 The unit will shut off when ice in the storage bin
touches the bin thermostat well and will auto-
matically cycle to keep the bin full.
0 The storage bin is not refrigerated and some
meltage WIII occur. This, too, varies with the room
temperature.
0 The unit needs good air circulation to perform
efficiently. Keep the front grill and the condenser
clean.
0 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
0 For complete operating Information. refer to the
Use and Care Guide.
0 Before starting, wash out Intenor of cabinet with a
Baking Soda solution (2 tablespoons soda to a
quart of warm water). Rinse thoroughly.
0 Make certain the water is turned on
0 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.

UNIT WIRING DIAGRAM
This model operates at 115 volts except for the
cutter grid circuit which operates at 8.5 volts at 1
amp.
he compressor runs at all times except when the
bin thermostat becomes satisfied and opens up.
This de-energizes the system except for the trans-
former and cutter grid.
Under normal operating conditions, when the
evaporator reaches the preset temperature (+lO’
to -3O F, depending on thickness of ice) the
evaporator thermostat opens, terminating op-
eration of the fan motor and pump motor. The
hot gas solenoid and the water valve solenoid are
energized at this time and remain so until the
evaporator reaches 38 + 2’ F.
