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

•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

F. - 10

•Cut In at about 31 PSIG (with normal heat load)
