IV. Adjustment of Components

1. Adjustment of Water Regulating Valve (water-cooled model only)

The water regulating valve or also called “water regulator” is factory-adjusted. No adjustment is required under normal use. Adjust the water regulator , if necessary, using the following procedures.

1)Attach a pressure gauge to the high-side line of the system. Or prepare a thermometer to check the condenser drain temperature.

2)Rotate the adjustment screw by using a flat blade screwdriver, so that the pressure gauge shows 260 PSIG (R-404A models/-F type), or the thermometer reads 100 -104°F, in 5 minutes after the icemaking process starts. When the pressure exceeds 260 PSIG, or the condenser drain temperature exceeds 104°F, rotate the adjustment screw counterclock- wise.

3)Check that the pressure or the condenser drain temperature holds a stable setting.
