• A condenser water supply line shut-off valve and drain valve must be installed.
• In some areas, a back flow preventer may be required in the cooling water circuit.
• 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 drain 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 drain outlet temperature 5 minutes after a freeze 
cycle starts. If the condenser drain outlet temperature is not in the proper range, use a 
flat blade screwdriver to rotate the adjustment screw on the water-regulating valve until 
the temperature is in the proper range (rotate counterclockwise to raise temperature or 
clockwise to lower temperature).
