NOTE: The thermostatic expansion valve is non-adjustable on all models.

A complete understanding of the icemaker and hermetic refrigeration system is necessary before any adjustments are made. The refrigeration technician must use high and low side pressure readings, water, and air temperatures, plus general conditions of cleanliness to assess the refrigeration system sta- tus when making any adjustments.

All icemaker products are tested and adjusted at the factory prior to shipment where the ambient temper- ature ranges from 65oF to 90oF, depending on the season of the year.

Whenever a new icemaker is initally installed and started-up, it is imperative that the start-up operator make the following checks and readjustments for local conditions.

EXPANSION VALVE

You will find a thermal expansion valve on icemakers, which is used to control the amount of refrigerant flowing through the evaporator. Improperly installed or defective expansion valves may cause low pro- duction, soft ice, squeaking from evaporator and excessive load inside evaporator.

By using general refrigeration troubleshooting along with the pressure charts, you can easily determine whether or not the expansion valve is working properly.

ADJUSTMENT AND TROUBLESHOOTING

When troubleshooting the expansion valve, you must:

1.Be sure you have adequate water flowing into the evaporator, a clean and properly ventilated con- denser, and the system is properly charged and free of any restrictions. Also be sure compressor is operating properly.

2.Take reservoir water temperature and air temperature from condenser inlet and determine at what pressure unit should be running. On machines equipped with thermostatic valve there is NO adjust- ment. If correct pressure cannot be obtained, be sure system has time to stabilize, 10-15 minutes.

3.Be sure sensing bulb is located at outlet side of evaporator about 3-4 inches away from evaporator and be sure to insulate well and clamp tightly to tubing. If system pressures are still not adequate, take a second water and air temperature reading and go over other parts of the system for possible problems. If proper charge is questionable evacuate and recharge to nameplate and leak check. If valve still malfunctions replace valve.

Use general refrigeration system practices when replacing and recharging unit. After new valve is in place, go through previous monitored adjustments and troubleshooting to be sure valve is functioning properly.
