2. Water-Cooled Condenser
a) Connection to an Open Drain System
• Connecting potable water to the condenser will not aff ect
performance but may result in high use/waste.
• Condenser water supply inlet is 1/2" female pipe thread
(FPT). A minimum of 3/8" (10 mm) nominal copper water
tubing is recommended for the condenser water supply
line.
• A condenser water supply line shut-off valve and drain
valve should be installed.
• Condenser drain outlet is 3/8" FPT. A minimum of 3/8"
(10 mm) nominal hard pipe is recommended for the
condenser drain line.
• In some areas, a back fl ow 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 7°C and the condenser drain outlet temperature
must be in the 40°C to 46°C range. Once the icemaker
installation is complete, confi rm 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 fl at 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).
