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 may be mounted on guide rails or
cables for use with optional discharge elbow/base­
plate kits, or it may be mounted on a trash stand
with an optional discharge elbow.
If the pump is configured for a guide rail/guide
cable application, the pump will be equipped with
a rail guide shoe which connects to the discharge
optional elbow/baseplate. When lowered into
place, the pump is automatically and securely con­
nected to the elbow/baseplate and the piping sys­
tem. For information on installing the guide rails,
see the literature accompanying them.
NOTE
When engaging the guide shoe and elbow/base­
plate, make sure that the connection is not impeded
by mounting hardware, and that the guide shoe is
fully seated in the baseplate.
To install a pump configured for a guide rail/guide
cable application, engage the guide shoe at the
top of the guide rails and use a suitable lifting de­
vice attached to the lifting handle to lower the
pump into the wet well. When the pump and guide
shoe engages the discharge elbow/baseplate, it
will form an automatic seal.
If the pump is mounted on a trash stand, secure a
discharge hose or pipe to the optional discharge
elbow and use a suitable lifting device attached to
the lifting handle to lower the pump into the wet
well.
Make certain that the pump and stand sit level in
the wet well.
Regardless of the installation configuration, the
maximum recommended submergence depth
is 65 feet (20 meters).
After installation in the wet well, reel in any slack in
the cables so that they are not dragged into the
pump suction.
Piping
NOTE
Refer to Pump Performance in OPERATION -
SECTION C when determining the most efficient
piping installation.
No suction piping is required in a standard sub­
merged operation.
Either hose or rigid pipe may be used to make dis­
charge connections. The discharge line must be
independently supported to avoid vibration and
strain on the pump. For maximum pumping capac­
