Lifting
Pump unit weights will vary depending on the
mounting and drive provided. Check the shipping
tag on the unit packaging for the actual weight, and
use lifting equipment with appropriate capacity.
Drain the pump and remove all customer‐installed
equipment such as suction and discharge hoses
or piping before attempting to lift existing, installed
units.
Positioning the Pump
NOTE
Before installing and operating the pump, check
the direction of impeller rotation to ensure that the
pump is properly wired at the control box. See IM­
PELLER ROTATION, SECTION C.
This pump is designed to be operated mounted on
a stand with an optional suction elbow.
Install and secure the stand in the floor of the dry
pit.
Position the pump on the stand. Install the screws
through the suction elbow and stand and tighten
fully.
Make certain that the pump and stand sit level in
the dry pit.
Piping
NOTE
Refer to Pump Performance in OPERATION -
SECTION C when determining the most efficient
piping installation.
Either hose or rigid pipe may be used to make dis­
charge connections.
The discharge and suction lines must be inde­
pendently supported to avoid vibration and strain
on the pump. For maximum pumping capacity,
keep the lines as short and straight as possible. El­
bows and fittings used in a the lines increase fric­
tion losses; minimize their use.
It is recommended that a check valve or throttling
valve be installed in the discharge line to control si­
phoning or back flow when the pump is shut off.
ELECTRICAL CONNECTIONS
Install and operate this pump in accor­
dance with the National Electrical Code
and all local codes. Have a qualified
electrician perform all checks and con­
nections in this section.
Never attempt to alter the length of the
pump motor cable or to repair it with a
splice. The power cable and pump mo­
tor must be kept completely waterproof.
Serious damage to the pump and injury
or death to personnel can result from
any alteration to the cable.
Field Wiring Connections (Incoming Power)
Field wiring is not provided with this pump, and
must be supplied by the user. The field wiring must
be of the proper size and type to ensure an ade­
quate voltage supply to the pump. Voltage avail­
able at the motor must be within the range indi­
cated in Table B-2.
