4.7 MOTOR ROTATION DIRECTION CHECK - -

INSTALLATION
This can be accomplished by toggling between the
"I" (START) and "O" (STOP) push buttons on the
control panel. Verify proper rotation by observing
the motor shaft from the end opposite the compres-
sor unit, the shaft should be turning clockwise. If the
motor shaft is not turning clockwise, disconnect the
power to the starter and exchange any two of the
three power input leads, then re--check rotation. A
"Direction of Rotation" decal is located on the motor
to show proper motor/compressor rotation.
An alternative to this procedure is to monitor the
sump pressure gauge when pressing the "I"
(START) push button. If immediate pressure is
shown on the sump pressure gauge when the com-
pressor is started, then the proper motor rotation
has been achieved. If no pressure is indicated,
press the "O" (STOP) push button immediately.
This indicates improper motor rotation. Disconnect
the power to the starter and exchange any two of the
three power input leads. Recheck rotation as out-
lined above.
