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, con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
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).
