cover.
d. Toggle the On /
Off switch. This
will cycle the motor
“on” and then “off”.
e. Observe the
motor shaft as it
slows to a stop to
identify the rotation.
Correct rotation is
“clockwise”, when
viewed from the
rear of the motor. Incorrect rotation is “counter-
clockwise” when viewed from the rear of the motor.
If the shaft does not rotate when the unit is started,
the operator must identify the cause as outlined in
this manual’s troubleshooting and repair section.
f. If the unit is phased correctly, continue with the
start up procedure at step C. If the unit is phased
incorrect, continue with step 2.
2. To correct unit phase:
a. Disengage the electrical power supply to the unit at
the unit’s disconnect switch. Follow proper lockout
procedures before proceeding.
b. Once the electrical power supply is disengaged,
reverse any two power leads of the power cord at
the fused disconnect
terminals.
c. Note: The operator
must reverse the
power leads at the
disconnect only and
not at the power
entry terminals on
the unit’s electrical
panel (figure 3.2C).
The unit’s internal
electrical system
wiring is phased correctly at the factory and must
not be altered in the field.
3. To visually verify pump rotation, start the unit and observe
the pressure gauges. The To Process pressure will indicate
35-50 PSI more than the From Process pressure. In this
state, the pump rotation is correct (clockwise). If this is
not evident the unit is not correctly phased and should be
