• R-410A pressure is approximately 60% higher than R-22 pressure. • R-410A cylinders must not be allowed to exceed 125 F , they may leak or rupture. • R-410A must never be pressurized with a mixture of air , it may become ammable. • Servicing equipment and components must be specically designed for use with R-410A and dedicated to pre[...]

Proper refrigerant charge is essential to proper unit operation. Operating a unit with an improper refrigerant charge will result in reduced performance (capacity) and/or efciency . Accordingly , the use of proper charging methods during servicing will insure that the unit is functioning as designed and that its compressor will not be damaged. T[...]

3. Install a process tube to sealed system. 4. Make necessary repairs to system. 5. Evacuate system to 200 microns or less. 6. Weigh in refrigerant with the property quantity of R410-A 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 protecti[...]

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[...]

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 pr ocedur 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.
