D. ELECTRICAL CONNECTIONS
See data plate for current requirements to
determine wire size to be used for electrical
connections. All SCOTSMAN icemakers require
a solid earth wire.
All SCOTSMAN ice machines are supplied from
the factory completely pre-wired and require only
electrical power connections to wire cord provided
at the 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 installation of an
appropriate water filter or conditioner.

WATER SUPPLY - WATER COOLED MODELS
The water cooled versions of SCOTSMAN Ice
Makers require two separate inlet water supplies,
one for water sprayed for making the ice cubes
and the other for the water cooled condenser.
Connect the 3/4" male fitting of the water inlet,
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.
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
Connect the 3/4" male fitting of the condenser
water drain, utilizing a second flexible tubing to
the 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 level? (IMPORTANT)
2. Have all the electrical and plumbing
connections been made, and is the water supply
shut-off valve open?
3. Has the voltage been tested and checked
against the data plate rating?
4. Have the bin liner and cabinet been wiped
clean?
5. Have the bolts holding the compressor down
been checked to ensure that the compressor is
snugly fitted onto the mounting pads?
6. Has the owner/user been given the User
Manual and been instructed on the importance of
periodic maintenance checks?
7. 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.
