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.

WATER SUPPLY AND DRAIN
CONNECTIONS
GENERAL
When choosing the water supply for the ice flaker
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 scale build-up on the interior parts of the
water system while too soft water (with too lo
contents of mineral salts), will produce a very
hard flaker ice.
WATER SUPPLY
Connect the 3/4" GAS male of the water inlet
fitting, using the food grade flexible hose 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 DRAIN
The recommended drain tube is a plastic or
flexible hose 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).
Install a vertical open vent on drain line high point
at the unit drain connection to ensure good
draining.
The ideal drain receptacle is a trapped and
vented floor 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.

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.
Have the bolts holding the compressor down
been checked to ensure that the compressor is
snugly fitted onto the mounting pads?
8.
Check all refrigerant lines and conduit lines
to guard against vibrations and possible failure.
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 SCOTSMAN
Service Agency serving him?
