Technical Characteristics

Typical Cycle Time
15 - 20 minutes (time depends upon how clean unit is, plus the air and water temperatures).
Typical Harvest Ice Weight
1.6 to 1.8 lb. ice harvested per cycle.
Typical Low Side Pressure
25 PSIG just before harvest
Typical Freeze Cycle Discharge Pressure
Air cooled: 300 PSIG declining to 210 PSIG
Water cooled: 245 PSIG
Refrigerant Type / Charge
Air Cooled: R-404A / 17 ounces A series, 16 ounces B and Cseries
Water Cooled: R-404A / 9 ounces A series, 11 ounces B series and 10 ounces C series
Harvest Time:
Varies with ambient, usually about 1.5 - 2 minutes. Unit is in harvest until the curtain opens. The
unit may remain in harvest a maximum of 7 minutes, after which the machine returns to the freeze
cycle.
Typical Low Side Pressure, in harvest
85 - 100 PSIG
Typical Discharge Pressure in harvest
195 - 210 PSIG
Hi Pressure Cut Out
Cuts Out at (450 PSIG air cooled, 350 PSIG water cooled); Cuts In at 350 PSIG (air cooled)
Typical Compressor Amp Draw
Freeze: 6-7
Harvest: 7-8
Superheat
o
4-6 F. 10 minutes into freeze cycle. TXV is not adjustable.
Finish Freeze Time
4 minutes after cube size thermostat closes (indicator light on control board is ON in Timed Freeze)
Air cooled fan motor
16 watt rating; 1500 RPM; CW. Stops during harvest.
Compressor
Copeland hermetic, capacitor start, induction run.
Water Pump Motor
4 pole, unit bearing type.
Cube Size Control
Adjustable Cut In temperature as needed to obtain correct ice bridge thickness, about 8
Cut In at about 31 PSIG (with normal heat load)
