17. T AND TROUBLESHOOTING When troubleshooting the expansion valve you must first be sure you have adequate water flowing into evaporator a clean condenser unit is properly ventilated and system is properly charged and free from any restrictions Also be sure compressor is operating properly Second take reservoir water temperature and air temperature from condenser inlet and determine at what pressure unit should be running Machines are equipped with thermostatic valves there is NO adjustment If correct pressure cannot be obtained first be sure system has time to stabilize 10 15 minutes Second be sure sensing bulb is located at 12 00 position on 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 system for possible problems If proper charge is questionable evacuate and recharge to nameplate and leak check If valve still malfunctions replace valve When replacing valve be sure to bleed refrigerant gas from low side port so as not to lose refrigerant oil Use general refrigerant 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 NOTE Units with thermostatic expansion valve valve is located on bottom refrigerant line Sensi
