•Shut-off valves and drain valves must be installed at both the condenser water supply inlet and condenser return outlet.

•Minimum water flow to the condenser is 4 GPM.

•The pressure differential between the condenser water supply inlet and condenser return outlet must be no less than 10 PSIG.

•When using a glycol blend, the solution mixture should be less than 30% glycol.

•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 return 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 return outlet temperature 5 minutes after a freeze cycle starts. If the condenser return 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).
