General Information And Installation
This model is supplied from the factory completely
pre-wired and require only electrical power
connections to the wire cord provided at rear of the
unit.
Make sure that the ice machine is connected to its
own circuit and individually fused (see data plate
for maximum fuse size). This is a cord-connected
unit designed for 115 volt AC power, with a
maximum fuse size of 15 amps.
Low voltage can cause improper operation and
may be responsible for serious damage to the
overload switch and motor windings that is not
covered by warranty.
NOTE. All external wiring should conform to
national, state and local standards and regulations.
Check voltage on the line and the ice maker’s data
plate before connecting the unit. Extension cords
must not be used.
Location: If the unit is built into a cabinet with no
side ventilation, the ice production will be reduced
by 20% of rated capacity, restricted space of an
inch or so on each side will cause a 10%
reduction. Six inches of space to the left and right
will allow the unit to operate satisfactorily.
To keep your SCOTSMAN CUBER at peak
performance levels, periodic maintenance checks
must be carried out as indicated on Maintenance
and Cleaning section of this manual.

Water Supply And Drain Connections
CU0515
General
When choosing the water supply for the ice cuber
consideration should be given to:
a) Length of run
b) Water clarity and purity
c) Adequate water supply pressure
Low water pressure, below 20 psi may cause a
malfunction.
Water containing excessive minerals will tend to
produce cloudy colored ice cubes, plus scale
build-up on parts of the water system.
Water Supply
The recommended water supply line is a 3/8" o.d.
copper tube, the water pressure must have a
minimum incoming pressure of 20 psig.
Connect the tubing to the 3/4" GAS / BSPP thread
water inlet fitting at the back of the ice maker. An
adapter is available, the part numbers are:
F733219-03 and F640134-00.
Water Drain
The recommended drain tube is a plastic or flexible
tube with 18 mm (3/4") I.D. which runs to an open
trapped and vented drain.
Note: Although soft, easily kinked vinyl tubing is
not recommended for a drain, a short length of ¾”
ID vinyl tubing is required to connect a rigid drain
tube to the 20 mm (25/32”) fitting on the back of
the machine.
NOTE. The water supply and the water drain must
be installed to conform to the local code. In some
case a licensed plumber and/or a plumbing permit
is required.

any adjustment.
K. If required, adjust the length of the freezing
cycle by turning the knob of the cube size control
or evaporator thermostat located in front of the
control box until the correct ice cube size is
achieved.
If the ice cubes are shallow and cloudy, it is
possible that the ice maker runs short of water
during the end of the freezing cycle or, the quality
of the supplied water requires the use of an
appropriate water filter or conditioner.
L. During the defrost or harvest cycle hold a
handful of ice cubes against the bulb of the storage

Component Description
Water Pump
The water pump operates continually throughout
the freezing cycle. The pump forces the water from
the sump to the spray system and through the
spray nozzles so it sprays into the inverted cup
molds to be frozen into crystal clear ice cubes.
Water Inlet Solenoid Valve
The water inlet solenoid valve is energized only
during the defrost cycle. When energized it allows
a metered amount of incoming water to flow over
the evaporator cavity to assist the hot gas in
defrosting the ice cubes.
The water running over the evaporator cavity drops
by gravity, through the weep holes of the platen,
into the sump.
Hot Gas Solenoid Valve
The hot gas solenoid valve consists basically in
two parts: the valve body and the valve coil.
Located on the hot gas line, this valve is energized
by the contacts 3-2 of the evaporator thermostat
during the defrost cycle.
CU0515
Water Circuit, Freeze Cycle
During the defrost cycle the hot gas valve coil is
activated so to attract the hot gas valve piston in
order to give way to the hot gas discharged from
compressor to flow directly into the evaporator
serpentine to defrost the formed ice cubes.
Bin Thermostat
The bin thermostat control body is located in the
front of control box behind the front louvered panel.
The thermostat sensing tube is located into a bulb
holder on the side wall of the ice storage bin where
it automatically shuts the ice machine OFF when in
contact with the ice and re-starts the ice machine
when the ice is removed. Factory settings are 1oC
o
F) OUT and 4oC (39oF) IN.
(35
Cube Size Control (Evaporator Thermostat)
The cube size control (evaporator thermostat)
body is located in the front of control box behind
the front louvered panel; it’s basically a reverse
acting temperature control which closes contacts
3-2 when its temperature decreases and closes
the opposite contacts 3-4 when the temperature
rises.

The thermostat sensing bulb is located into a
plastic tube (bulb holder) secured by two clips
directly to the evaporator serpentine. This control
determines the length of the freezing cycle and
correspondingly the size of the cubes.
A lower setting will produce a larger cube
(oversize) while a higher setting a smaller cuber
(shallow size).
When closed on contacts 3-2 (adjustable between
o
-7.6
F. and 11.5oF.) it activates the defrost or
harvest cycle components. The cube size control is
pre-set at the factory (knob in the black dot
position) and doesn’t require any adjustment when
the ambient temperature remains between 15 and
o
30
C (60 and 90oF).
Fan Motor
The fan motor is electrically connected in parallel
to the water pump and it operates continuously
only during the freezing cycle keeping the proper
head pressure by circulating air through the
condenser fins.
Compressor
The hermetic compressor is used to circulate
refrigerant throughout the entire system. It
compresses the low pressure refrigerant vapor
causing its temperature to rise and become high
pressure hot vapor (hot gas) which is then
released through the discharge valve.
Water Spray System
Sprays the water into each individual cup to be
frozen into ice.
Harvest continues until the thermostat warms up to
about 36
freeze mode.

Maintenance And Cleaning Instructions
CU0515
GENERAL
The periods and the procedures for maintenance
and cleaning are given as guides and are not to be
construed as absolute or invariable. Cleaning,
especially, will vary depending upon local water
and ambient conditions and the ice volume
produced; and, each ice machine must be
maintained individually, in accordance with its
particular location requirements.
Ice Machine
The following maintenance should be scheduled at
least two times per year on these ice machines.
1. Check and/or replace the water filter (if used).
2. Check that the ice machine is leveled in side to
side and in front to rear directions.
3. Check for water leaks and tighten drain line
connections. Pour water down bin drain line to be
sure that drain line is open and clear.
4. Check size, condition and texture of ice cubes.
Perform adjustment of cube size control as
required.
Clean - Replace Of Air Condenser Filter
1. Withdraw the air filter from the front through the
opening of the front panel.
2. Remove the front panel.
3. Blow pressurized air on the opposite direction of
the condenser air flow so to remove the
dust accumulated. If pressurized air is not
available, use tap water always in the counter flow
air direction. Once cleaned shake it so to remove
most of the accumulated water, then dry it using an
hair dryer.
NOTE. In case the air filter strainer is damaged
replace it with a new one.
4. Return the front panel to its normal position.
5. Install filter by pushing it through the front panel
opening.
5. Check the bin thermostat to test shut-off.
Put a scoop full of ice cubes in contact with the bin
thermostat bulb for at least one minute.
This should cause the ice maker to shut off. Within
few seconds after the removal of the ice from bin
thermostat bulb, the ice machine restarts.
NOTE. Within minutes after the ice is removed
from the bulb holder tube, the sensing bulb inside
the tube will warm up and cause the ice machine
to restart. This control is factory set and should not
be reset until testing is performed.
6. Check for refrigerant leaks.
NOTE. Standard equipped with an air condenser
filter as well as a Cleaning Reminder Board to
remind to the end user the need for the cleaning of
