temperature should not drop below 45°F (7°C) and the condenser return 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 return outlet temperature 5 minutes
after a freeze cycle starts. If the outlet temperature is not in the proper range, adjust the
water-regulating valve to bring it into range.
