TYPICAL INSTALLATION ON A REFRIGERANT PLANT
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 the 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.
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

WATER DRAIN
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 tubing supply with the to
unit 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
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).
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.
