2. Water-Cooled Condenser
a) Connection to an Open Drain System
•Condenser water supply inlet is 1/2" female pipe thread (FPT). A minimum of 3/8" nominal
ID copper water tubing or equivalent is required for the condenser water supply line.
•A condenser water supply line
•Condenser drain outlet is 3/8" FPT. A minimum of 3/8" nominal ID hard pipe or equivalent is required for the condenser drain line.
•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).
