ELECTRICAL CONNECTIONS

See data plate for current requirements to
determine wire size to be used on electrical
connections. All icemakers require a solid earth
wire.
The ice machines are supplied from the factory
completely pre-wired and require only electrical
power connections to wire cord provided on the
back 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
built-up on parts of the water system.
Water supply
Connect the 3/4" male fitting of the solenoid
water inlet valve, using the 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.
Water supply - Water cooled models
(SCE 90 - 105)
The water cooled versions of SCE 90 - 105 models
require two separate inlet water supplies, one for
the water sprayed for making the ice cubes and
the other for the water cooled condenser.
Connect the 3/4" male fitting of the water
regulating valve using the flexible hose supplied
with the unit 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. 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 vertical open vent, at the unit drain connection,
is also required for proper sump drainage.
Water drain - Water cooled models
The water drain line from the condenser, on
water cooled versions, is internally connected
with the drain fitting of the unit.
It is strongly recommended therefore to install a
vertical open vent on unit drain line high point to
ensure good draining and to direct the drain line
to a trapped and vented floor drain receptacle.
This to make sure of the proper flow of the
drained water as, in case of poor drainage, the
water ranning out from the condenser may
inopportunely flow, through the unit drain tubing,
into the ice storage bin.
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.
