COOLING TOWER APPLICATIONSWater Cooled Models OnlyA water-cooling tower installation does not requiremodification of the ice machine. The water regulatorvalve for the condenser continues to control therefrigeration discharge pressure.It is necessary to know the amount of heat rejected,and the pressure drop through the condenser andwater valves (inlet to outlet) when using a coolingtower on an ice machine.• Water entering the condenser must not exceed90°F (32.2°C).• Water flow through the condenser must notexceed 5 gallons (19 liters) per minute.• Allow for a pressure drop of 7 psig (.48 bar)between the condenser water inlet and the outletof the ice machine.• Water exiting the condenser must not exceed110°F (43.3°C).! CautionPlumbing must conform to state and local codes32 Part Number 80-01111-9 7/10
