DJUSTMENTS
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 status when making any adjustments.
All icemaker products are tested and adjusted at the factory prior to shipment where the ambient temperature
ranges from 65° to 90°F, depending on the season of the year.
Whenever a new icemaker product is initially installed and started–up, it is imperative that the start–up operation
make the following checks and/or readjustments for local conditions.

ALVE
You will find a thermostatic 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 production, soft ice,
squeaking from evaporator and excessive load inside evaporator.
By using general refrigeration system troubleshooting along with the pressure charts you can easily determine
whether or not the expansion valve is working properly.
