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.
Underchar ged R efrigerant 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 R efrigerant System T roubleshooting a restricted refrigerant system can be GLI¿FXOW 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.
Lock ed Rotor V oltage (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 compressor 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.
