7. Procedure to set proper rotation:
a. Supply electrical power to the unit. Once the correct
voltage is supplied to the unit, the POWER switch
ontheunit’scontrolpanelwillilluminate.Adjustthe
setpoint to 70°F or higher to prevent the compressor
from activating during this procedure.
b. Remove all necessary cover panels to access the
pump motor.
c. Locatethepump’selectricmotor(gure3.2C).The
operator must identify the motor shaft inside the
electric motor housing. The motor shaft can be seen
through the vent slots in the motor housing or by
removing the shaft cover.
d. ToggletheilluminatedON/OFFSWITCH(gure
3.2D). This will quickly cycle the pump motor “on”
and then “off”.
e. Observe the motor shaft. When the ON/OFF
SWITCH is on, the motor shaft will rotate. When
switched off, the shaft will slowly “coast” to a stop.
As the shaft slows, the operator can identify the
rotation of the
motor shaft.
Correct rotation
(correct phase) is
“clockwise”, when
viewed from the
rear of the motor.
Incorrect rotation
is “counter-
clockwise”
(incorrect phase)
Figure 3.2D
Illuminated On/Off switch
Correct shaft rotation is clockwise.
WARNING: The electrical power is engaged at this point and caution
must be observed while the electrical supply is engaged and cabinet
panels are removed and opened.
