SERVICE SPECIFICATION
In servicing a machine, it is often useful to
compare that individual unit operating
characteristics to those of a normally operating
machine. The data that follows gives those
characteristics; however, be aware that these
values are for new, clean machine operating at
21 ℃ ambient and 15 ℃ water. Use these
numbers as a guideline only.
COMPONENT
Reservoir Level
SVD152………………..65~69mm
SVD222………………..85~90mm
SVD 203/303 ............... 80~85 mm
SVD 503 .......................100~105 mm
Cube Size Control Ice Sensor - distance from
evaporator 3~5 mm
High Pressure Safety Switch.
SVD 152-222-203-303-503:
Cut in 23 bar
Cut out 33 bar
OPERATING CHARACTERISTICS
On air-cooled models during the freezing cycle,
the discharge pressure is maintained between
two preset values by means of fan control
(condenser sensor); and at the same time, the
suction pressure will also decline reaching its
lowest point just before harvest. Compressor
amps experience a similar drop.
On water-cooled, the discharge pressure is
constantly, maintained during the freeze cycle
by the water regulating valve. However, suction
pressure and compressor amps, will still
decline as the machine freezes ice.
Refrigerant metering device
Thermostatic expansion valve.

NOTE:
Always check nameplate on individual ice machine for special refrigerant charge before
charging the refrigeration system. Such refrigerant charge is the average charge for the SVD
Modular Cubers. However it is important to check nameplate of each machine.
