18. SYSTEM ADJUSTMENTS A complete understanding of the icemaker and hermetic refrigeration system is necessary before any adjust ments are made The refrigeration technician must use high and low side pressure readings water and air tem peratures 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 F to 90 F depending on the season of the year Whenever a new icemaker is initially 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 Wilshire ice makers which is used to control the amount of refriger ant flowing through the evaporator Improperly installed or defective expansion valves may cause low produc tion soft ice squeaking from evaporator and excessive load inside evaporator By using general refrigeration trouble shooting 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 condenser and the system is properly charged and free of any restrictions Also be sure compressor is o
