b) Connection to a Closed Loop System 
• Condenser water supply inlet is 1/" female pipe thread (FPT). A minimum of 3/8" OD 

copper tubing is recommended for the condenser water supply line.

• Condenser return outlet is 1/" FPT. A minimum of 3/8" OD hard pipe is recommended for 

the condenser return line.

• Shut-off valves and drain valves should be installed at both the condenser water supply 

inlet and condenser return outlet.

• The water supply to the condenser should not drop below 4 GPM. 
• The pressure differential between the condenser water supply inlet and condenser return 

outlet must be no less than 10 PSIG.

• When using a glycol blend, the solution mixture should be less than 30% glycol.
• In order to maintain the proper high side pressure, the condenser water supply inlet 

temperature should not drop below 45°F (7°C) and the condenser return outlet 
temperature must be in the 104°F to 115°F (40°C to 46°C) range. Once the icemaker 
installation is complete, confirm the condenser return outlet temperature 5 minutes 
after a freeze cycle starts. If the outlet temperature is not in the proper range, adjust the 
water-regulating valve to bring it into range.
