7 Functional Component Defi nitions MECHANICAL COMPONENTS Vent door Allows introduction of fresh air into the room and/or exhausts stale room air outside (on select models.) Plenum assembly Diffuser with directional louvers used to direct the conditioned airfl ow. Blower wheel Attaches to the indoor...

8 In the case of the capillary tube this is accomplished (by design) through size (and length) of device, and the pressure difference present across the device. Since the evaporator coil is under a lower pressure (due to the suction created by the compressor) than the liquid line, the liquid refrige...

9 EQUIPMENT REQUIRED 1. Voltmeter 2. Ammeter 3. Ohmmeter 4. E.P.A. Approved Refrigerant Recovery System. 5. Vacuum Pump (capable of 200 microns or less vacuum.) 6. Acetylene Welder 7. Electronic Halogen Leak Detector (G.E. Type H- 6 or equivalent.) 8. Accurate refrigerant charge measuring device suc...

10 NOTE: In order to access the sealed system it will be necessary to install Schrader type fi ttings to the process tubes on the discharge and suction of the compressor. Proper refrigerant recovery procedures need to be adhered to as outlined in EPA Regulations. THIS SHOULD ONLY BE ATTEMPTED BY QUA...

13 Problem Possible Cause Action Compressor does not run Low voltage Check voltage at compressor. 115V & 230V units will operate at 10% voltage variance T-stat not set cold enough or inoperative Set t-stat to coldest position. Test t-stat & replace if inoperative Compressor hums but cuts off...

17 Problem Possible Cause Action Room temperature uneven (Heating cycle) Heat anticipator (resistor) shorted (on applicable models) Disconnect power to unit. Remove resistor from t-stat bulb block. Plus in unit & allow to operate. Feel resistor for heat. If not heat, replace resistor Wide differ...
