NOTE:
Compressor start assist devices (capacitor and start potential relay) may be required
on WCX units with scroll compressors for installations with long line length, unusually
high or low ambient operating conditions, thermostatic expansion valves or any
other situation which can lead to slow o cycle pressure equalization and excessive
compressor starting problems.
NOTE:
R-410A refrigerant oil is not compatible with R-22 oil. Therefore, when R-410A
outdoor units are replacing existing R-22 outdoor units, the indoor evaporator
coil must be replaced with a new one, the coil must include an R-410A TXV, and
the interconnecting refrigerant lines ushed.
