5. SERVICE SPECIFICATION
• In servicing a machine, it is often, useful to compare that in
dividual units operating characteristics to those of a normally
o
perating machine.
• The data that follows gives those characteristics; however, be
aware that these values are for NEW, CLEAN machine oper
ating at 21 °C ambient and 15 °C water.
U
SE THESE NUMBERS AS A GUIDELINE ONLY.
Refrigerant charge R 404 A  gr.
Refrigerant metering device
Thermostatic expansion valve.
Nota: Always check nameplate on individual icemachine for
special refrigerant charge before charging the refrigeration sy-
stem.
Such refrigerant charge is the average charge for the M Modular
Cubers. However it is important to check nameplate for each
machine.
5.1 OPERATING CHARACTERISTICS
• On aircooled models during the freezing cycle, the dis
c
harge 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 it’s low
est point just before harvest. Compressor amps experience a
similar drop.
O
n watercooled, the discharge pressure is constantly, main
tained during the freeze cycle by the water regulating valve.
However, suction pressure and compressor amps, will still de
cline as the machine freezes ice.
