CAUTION
SCROLL COMPRESSORS REQUIRE PROPER ROTATION TO
OPERATE CORRECTLY. UNITS ARE PROPERLY PHASED AT
THE FACTORY. DO NOT CHANGE THE INTERNAL WIRING TO
MAKE THE BLOWER, CONDENSER FANS, OR COMPRESSOR
ROTATE CORRECTLY.
PHASING
YORK Saber units are properly phased at the factory. Check
for proper compressor rotation. If the blower or compressors
rotate in the wrong direction at start up, the electrical
connection to the unit is mis-phased. Change the incoming
line connection phasing to obtain proper rotation. (Scroll
compressors operate in only one direction. If the scroll is
drawing low amperage, has similar suction and discharge
pressures, or producing a high noise level, the scroll is
mis-phased).
