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.
