C-4.4) Wire Size:
Consult a qualifi ed electrician for proper wire size if additional
power cable is required. See table for electrical information.
SECTION: D START-UP OPERATION
D-1) Check Voltage and Phase:
Before operating pump, compare the voltage and phase
information stamped on the pump identifi cation plate to the
available power.
D-2) Check Pump Rotation:
Before putting pump into service for the fi rst time, the motor
rotation must be checked. Improper motor rotation can result
in poor pump performance and can damage the motor and/or
pump. To check the rotation, suspend the pump freely, mo-
mentarily apply power and observe the “kickback”. “Kickback”
should always be in a counter-clockwise direction as viewed
from the top of the pump motor housing.
D-2.1) Incorrect Rotation for Three-Phase Pumps:
In the event that the rotation is incorrect for a three-phase
installation, interchange any two power cable leads at the
control box.
DO NOT change leads in the cable housing in
the motor. Recheck the “kickback” rotation again by momen-
tarily applying power.
D-2.2) Incorrect Rotation for Single-Phase Pumps:
In the unlikely event that the rotation is incorrect for a single
phase pump, contact a Barnes Service Center.
D-3) Start-Up Report:
Included at the end of this manual is a start-up report sheet,
this sheet is to be completed as applicable. Return one copy
to Barnes and store the second in the control panel or with
the pump manual if no control panel is used. It is important to
record this data at initial start-up since it will be useful to refer
to should servicing the pump be required in the future.
D-3.1) Identifi cation Plate:
Record the numbers from the pump identifi cation plate on
both START-UP REPORTS provided at the end of the manual
for future reference.
D-3.2) Insulation Test:
Before the pump is put into service, an insulation (megger)
test should be performed on the motor. The resistance values
(ohms) as well as the voltage (volts) and current (amps)
should be recorded on the start-up report.
D-3.3) Pump-Down Test :
After the pump has been properly wired and lowered into the
basin, sump or lift station, it is advisable to check the system
by fi lling with liquid and allowing the pump to operate through
its pumping cycle. The time needed to empty the system, or
pump-down time along with the volume of water, should be
recorded on the start-up report.
SECTION E: PREVENTATIVE MAINTENANCE
As the motor is oil fi lled, no lubrication or other maintenance
is required, and generally Crane Pumps & Systems will give
very reliable service and can be expected to operate for years
on normal sewage pumping without failing. However as with
any mechanical piece of equipment a preventive mainte-
nance program is recommended and suggested to include
the following checks:
1) Inspect motor and seal chambers for oil level and
contamination and repair as required per section F-1.
2) Inspect impeller and body for excessive build-up or
clogging and repair as required per section F-2.
3) Inspect motor and bearings and replace as required per
section F-3.
4) Inspect seal and diaphragm for wear or leakage and
repair as required per section F-4.
5) Inspect suction elbow cleanout for excessive build-up or
clogging, service per section F-5.
