c.
Locate the electric motor and 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.
On the instrument, quickly press the
green Power icon and the quickly press
the red Power off Icon twice.
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.
4.
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. The unit’s internal
electrical system wiring is phased
correctly at the factory and must not be
altered in the field.
5. To verify pump rotation via pressure gauges. 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. If not evident
the unit is not correctly phased and should be corrected as outlined in step 4.
C. Process Flow Adjustments
1.
The operator must determine and set proper water flow rate for the most efficient
and trouble free operation.
DO NOT reverse power leads at the unit’s
power entry
Remove shaft cover to view the motor shaft
Correct rotation is clockwise when viewed from
the rear of the motor.
