Adjustment; Expansion Valve - Hoshizaki IM-30CWNE Service Manual

VII. ADJUSTMENT

1. EXPANSION VALVE

The expansion valve is factory-adjusted. Do not adjust it except at replacement or
service. Adjust the valve setting, if necessary, as follows:
1) Remove the cap nut.
2) Rotate the adjust screw by using a flat blade screwdriver.
3) Watch holes of ice cubes produced. Standard setting is that evaporator inlet side
and outlet side cubes have almost the same diameters. To make the inlet side larger,
rotate 90 - 180° clockwise. Smaller, counterclockwise. Do not rotate more than 180°
at a time.
Over adjustment of the valve may result in liquid refrigerant return causing
freezing to the suction line and severe damage to the compressor.
