• 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).

Be sure there is sufficient
extra water supply line and
drain line for the appliance
to be pulled out for service.
Separate piping to approved
drain. Leave a 2-inch (5-cm)
vertical air gap between the
end of each pipe and the
drain.
