A. INTRODUCTION
This manual provides the specifications and the
step-by-step procedures for the installation, startup and operation, maintenance and cleaning for
the Cube Dispenser.
SCOTSMAN dispenser is quality designed,
engineered and manufactured, thoroughly tested
providing the utmost in flexibility to fit the needs
of a particular user.
In has been engineered to our own rigid safety
and performance standards.
NOTE
. To retain the safety and performance
built into this icemaker, it is important that
installation and maintenance be conducted
in the manner outlined in this manual.
B. UNPACKING AND INSPECTION
1. Call your authorized Distributor or Dealer
for proper installation.
2. Visually inspect the exterior of the packing
and skid. Any severe damage noted should be
reported to the delivering carrier and a concealed
damage claim form filled in subjet to inspection of
the contents with the carrier’s representative
present.
3. a) Cut and remove the plastic strip securing
the carton box to the skid.
b) Remove the packing nails securing the
carton box to the skid.
c) Cut open the top of the carton and remove
the polystyre protection sheet.
d) Pull out the polystyre posts from the
corners and then remove the carton.
4. Remove the rear panel of the unit and
inspect for any concealed damage. Notify carrier
of your claim for the concealed damage as steted
in step 2 above.
5. Remove top and upper front panel then
remove all internal support packing and masking
tape.
6. Check that refrigerant lines do not rub
against or touch other lines or surfaces, and that
the fan blade moves freely.
7. Check that the compressor fits snugly onto
all its mounting pads.
8. Use clean damp cloth to wipe the surfaces
inside the storage bin and the outside of the
cabinet.
GENERAL INFORMATION AND INSTALLATION
9. See data plate on the rear side of the unit
and check that local main voltage corresponds
with the voltage specified on it.
CAUTION. Incorrect voltage supplied to
the icemaker will void your parts
replacement program.
10. Remove the manufacturer’s registration
card from the inside of the User Manual and fillin all parts including: Model and Serial Number
taken from the data plate.
Forward the completed self-addressed
registration card to the Factory.
C. LOCATION AND LEVELLING
WARNING. Ice cubers dispenser is designed
for indoor installation only. Extended
periods of operation at temperatures
exceeding the following limitations will
constitute misuse under the terms of the
Manu-facturer’s Limited Warranty
resulting in LOSS of warranty coverage.
1. Position the unit in the selected permanent
location.
Criteria for selection of location include:
a) Minimum room temperature 10°C (50°F)
and maximum room temperature 40°C (100°F).
b) Water inlet temperatures: minimum 5°C
(40°F) and maximum 35°C (90°F).
c) Well ventilated location for air cooled
models.
d) Service access: adequate space must
be left for all service connections through the rear
of the ice maker. A minimum clearance of 15 cm
(6") must be left at the sides of the unit for routing
cooling air drawn into and exhausted out of the
compartment to maintain proper condensing
operation of air cooled models.
2. Level the unit in both the left to right and
front to rear directions.
D. ELECTRICAL CONNECTIONS
See data plate for current requirements to
determine wire size to be used for electrical
connections. Ice dispenser requires a solid earth
wire.
It is supplied from the factory completely prewired 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 fuse size).
The maximum allowable voltage variation should
not exceed -10% and +10% of the data plate
rating. Low voltage can cause faulty functioning
and may be responsible for serious damage to
the overload switch and motor windings.
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.
E. WATER SUPPLY AND DRAIN
CONNECTIONS
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
Since water is the most important single ingredient
in producting ice you cannot emphasize too
much the three items listed above.
Low water pressure, below 1 bar may cause
malfunction of the ice maker unit.
Water containing excessive minerals will tend to
produce cloudy coloured ice cubes, plus scale
build-up on parts of the water system.
WATER SUPPLY
Connect the 3/4" male fitting of the solenoid
water inlet valve, using the flexible tube supplied,
to the cold water supply line with regular plumbing
fitting and a shut-off valve installed in an
accessible position between the water supply
line and the unit.
If water contains a high level of impurities, it is
advisable to consider the use of an appropriate
water filter or conditioner.
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. When the
drain is a long run, allow 3 cm pitch per meter
(1/4" pitch per foot).
A vent at the unit drain connection is also required
for proper sump drainage.
WATER DRAIN - WATER COOLED MODELS
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.
The water supply and the water drain
must be installed to conform with the local
code. In some case a licensed plumber and/
or a plumbing permit is required.
F. FINAL CHECK LIST
1. Is the unit in a room where ambient
temperatures are within a minimum of 10°C
(50°F) even in winter months?
2. Is there at least a 15 cm (6") clearance
around the unit for proper air circulation?
3. Is the unit level? (IMPORTANT)
4. Have all the electrical and plumbing
connections been made, and is the water supply
shut-off valve open?
5. Has the voltage been tested and checked
against the data plate rating?
6. Has the water supply pressure been
checked to ensure a water pressure of at least
1 bar (14 psi).
7. Check all refrigerant lines and conduit lines
to guard against vibrations and possible failure.
8. Have the bolts holding the compressor down
been checked to ensure that the compressor is
snugly fitted onto the mounting pads?
9. Have the bin liner and cabinet been wiped
clean?
10. Has the owner/user been given the User
Manual and been instructed on the importance of
periodic maintenance checks?
11. Has the Manufacturer’s registration card
been filled in properly? Check for correct model
and serial number against the serial plate and
mail the registration card to the factory.
12. Has the owner been given the name and
the phone number of the authorized Service
Agency serving him?
