The following information should be read carefully prior to installing units with scroll compressors.
1.PUMP DOWN PROCEDURE
CAUTION: Scroll compressors should never be used to evacuate the air conditioning system. Vacuums this low can cause
internal electrical arcing resulting in a damaged or failed compressor.
2.CRANKCASE HEATER
Scroll equipped units do not have or do not require a crankcase heater.
3.TIME DELAY COMPONENT
The time delay is located in the low voltage control circuit. When the compressor shuts off due to thermostat operation or a
power failure, this components keeps the compressor off for at least 30 seconds which allows the system pressure to equalize.
4.UNBRAZING SYSTEM COMPONENTS
If the refrigerant charge is removed from a scroll equipped unit by bleeding the high side only, it is sometimes possible for the
scrolls to seal, preventing pressure equalization through the compressor. This may leave the low side shell and suction line tubing
pressurized. If a brazing torch is then applied to the low side while the low side shell and suction line contains pressure, the
pressurized refrigerant and oil mixture could ignite when it escapes and contacts the brazing flame. To prevent this occurrence,
it is important to check both the high and low side with manifold gauge before unbrazing, or in the case of repairing a unit on an
assembly line, bleed refrigerant from both the high and low side.
