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 mounted on a stand in
a dry pit with an optional suction elbow.
Install and secure the stand in the floor of the dry
pit. Install the upper gasket on the stand, and posi­
tion the pump on the stand. Install the lower gasket
on the suction elbow and secure the elbow to the
stand and pump with the provided screws.
Align the elbow with the system suction piping and
secure. Align the pump casing flange with the sys­
tem discharge piping and secure.
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.
This pump is designed for operation with an op­
tional discharge elbow. Use rigid pipe to make dis­
charge connections to the elbow.
The discharge line must be independently sup­
ported to avoid vibration and strain on the pump.
For maximum pumping capacity, keep the line as
short and straight as possible. Elbows and fittings
used in a discharge line increase friction 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.
