Failure to do so may result in personal injury , or death. Many motor capacitors are internally fused. Shorting the terminals will blow the fuse, ruining the capacitor . A 20,000 ohm 2 wat[...]

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 . During the heating mode of operation, it is necessary that water be removed to prevent it from fre[...]

Make Necessary Sealed System Repairs And V acuum System. Crimp Process T ube Line And Solder End Shut. Do Not Leave A Service V alve In The Sealed System. Pr[...]

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. Proper safety procedures must be followed, and proper protective[...]

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. T o check for an undercharged system, turn the unit on, all[...]

R estricted Refrigerant System T roubleshooting a restricted refrigerant system can be difcult. 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. A partial restriction allows some of the refrigerant to circulate t[...]

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. 3. Switc[...]

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 . The solenoid is energized during th[...]

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. 2. Unplug line voltage lead from reversing valve coil. 3. Check for electrical continuit[...]

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. Using a voltmeter , attach one lead of the meter to the run “R” terminal on the compressor and the other lead to the common “C” terminal of t[...]

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”). Add values “C” to “S” and “C” to “[...]

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. PROPER HANDLING OF RECOVERED REFRIGERANT ACCORDING TO EP A REGULA TIONS IS REQUIRED. Do n[...]
