a) Connection to an Open Drain System 
• Condenser water supply inlet is 1/2" female pipe thread (FPT). A minimum of 1/4" nominal

ID copper water tubing or equivalent is required 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 1/4" 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 condenser water supply line.
• 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).

Separate piping to approved 

drain. Leave a 2-inch (5-cm) 

vertical air gap between the 

end of each pipe and the 

drain.
