16 CAP ACIT ORS ELECTRIC SHOCK HAZARD W ARNING T urn off electric power before servicing. Discharge capacitor with a 20,000 Ohm 2 W att resistor before handling. Failure to do so may result in personal injury , or death. Many motor capacitors are internally fused.
17 DRAIN P AN V AL VE During the cooling mode of operation, condensate which collects in the drain pan is picked up by the condenser fan blade and sprayed onto the condenser coil. This as - sists in cooling the refrigerant plus evaporating the water .
Suction Line Evaporator Coil Metering Device Refrigerant Strainer Discharge Line Condenser Coil Compressor Refrigerant Drier Liquid Line A good understanding of the basic operation of the refrigeration system is essential for the service technician.
R efrigerant Char ging NOTE: Because The W allMaster System Is A Sealed System, Service Process T ubes Will Have T o Be Installed. First Install A Line T ap And Remove Refrigerant From System. Make Necessary Sealed System Repairs And V acuum System. Crimp Process T ube Line And Solder End Shut.
3. Install a process tube to sealed system. 4. Make necessary repairs to system. 5. Evacuate system to 300 microns or less. 6. Weigh in refrigerant with the property quantity of R-22 refrigerant. 7. Start unit, and verify performance. 8. Crimp the process tube and solder the end shut.
Underchar ged R efriger ant Systems An undercharged system will result in poor performance (low pressures, etc.) in both the heating and cooling cycle. Whenever you service a unit with an undercharge of refrigerant, always suspect a leak. The leak must be repaired before charging the unit.
R estricted Refrigerant System T roubleshooting a restricted refrigerant system can be difcult. The following procedures are the more common problems and solutions to these problems. There are two types of refrigerant restrictions: Partial restrictions and complete restrictions.
METERING DEVICE Capillar y T ube Systems All units are equipped with capillary tube metering devices. Checking for restricted capillary tubes. 1. Connect pressure gauges to unit. 2. Start the unit in the cooling mode. If after a few minutes of operation the pressures are normal, the check valve and the cooling capillary are not restricted.
NOTE: System operating pressures must be near normal before valve can shift . REVERSING V AL VE DESCRIPTION/OPERA TION The Reversing V alve controls the direction of refrigerant ow to the indoor and outdoor coils. It consists of a pressure-operated, main valve and a pilot valve actuated by a solenoid plunger .
Reversing V alve in Heating Mode TESTING THE COIL The solenoid coil is an electromagnetic type coil mounted on the reversing valve and is energized during the operation of the compressor in the heating cycle. 1. T urn of f high voltage electrical power to unit.
8. Pressurize sealed system with a combination of R-22 and nitrogen and check for leaks, using a suitable leak detector . Recover refrigerant per EP A guidelines. 9. Once the sealed system is leak free, install solenoid coil on new valve and charge the sealed system by weighing in the proper amount and type of refrigerant as shown on rating plate.
Lock ed Rotor V olta ge (L.R.V .) T est Locked rotor voltage (L.R.V .) is the actual voltage available at the compressor under a stalled condition. Single Phase Connections Disconnect power from unit.
Single Phase Resistance T est Remove the leads from the compressor terminals and set the ohmmeter on the lowest scale (R x 1). T ouch the leads of the ohmmeter from terminals common to start (“C” to “S”). Next, touch the leads of the ohmmeter from terminals common to run (“C” to “R”).
R ecommended procedur e for compr essor replacement 1. Be certain to perform all necessary electrical and refrigeration tests to be sure the compressor is actually defective before replacing. 2. Recover all refrigerant from the system though the process tubes.
1. 2. 3. 4. 5. ELECTRIC SHOCK HAZARD W ARNING T urn off electric power before service or installation. Failure to do so may result in personal injury , or death. S e a l e d R e f r i ge r a ti o n Sy s te m c o n t a i n s r e f r i g e r an t and oil under high pressure.
R OUTINE MAINTENANCE AIR FIL TER Clean the unit air intake lter at least every 300 to 350 hours of operation. Clean the lters with a mild detergent in warm water and allow to dry thoroughly before reinstalling. Units are to be inspected and serviced by qualied service personnel only .

33 COOLING ONL Y ROOM AIR CONDITIONERS: TR OUBLESHOO TING TIPS n o i t c A e s u a C e l b i s s o P m e l b o r P Compressor does not run Low voltage Check voltage at compressor . 1 15V & 230V units will operate at 10% voltage variance T -stat not set cold enough or inoperative Set t-stat to coldest position.
n o i t c A e s u a C e l b i s s o P m e l b o r P Unit does not run Fuse blown or circuit tripped Replace fuse, reset breaker . If repeats, check fuse or breaker size.
35 n o i t c A e s u a C e l b i s s o P m e l b o r P Compressor runs for short periods only . Cycles on overload Overload inoperative. Opens too soon Check operation of unit.
Problem Possible Cause Action W ater “spitting” into room Sublimation: When unconditioned saturated, outside air mixes with conditioned air , condensation forms on the cooler surfaces Ensure that foam gaskets are installed in between window panes & in between the unit & the sleeve.
37 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.
38 n o i t c A e s u a C e l b i s s o P m e l b o r P Unit cools when heat is called for Incorrect wiring Refer to applicable wiring diagram Defective solenoid coil Check for continuity of coil Reversing valve fails to shift Block condenser coil & switch unit to cooling.
