INSTALLATION
Do not
allow the free end of the power
cable to enter the liquid being pumped.
The free end of the cable
must
be kept dry
to prevent liquid from wicking through the
cable and into the motor.
NOTE
Refer to the performance curve in the Parts List
Manual
when determining the most efficient piping
installation.
The recommended maximum sub-
mergence depth is 65 feet.
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.
The pump is equipped with a guide shoe for
mounting on optional guide rails. A discharge el-
bow/baseplate is also available as optional equip-
ment.
Use a suitable lifting device attached to the lifting
handle to lift the pump. Engage the guide shoe at
the top of the guide rails, and lower the pump into
the sump. When lowered into place, the guide
shoe connects to the optional discharge elbow/
baseplate, and the pump is automatically and se-
curely sealed to the piping system; the pump can
be removed or installed without personnel entering
the wet well.
For information on installing the guide rails, see the
literature accompanying the rails. Be sure theins-
tallation allows the pump to slide without binding
on the rails or baseplate.
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.
Reel in any slack control cable so that it is not
dragged into the pump suction.
Piping
No suction piping is required in a standard installa-
tion.
The optional discharge elbow/baseplate is drilled
for connection to a discharge flange. Either hose
or rigid pipe may be used to make discharge con-
nections.
If rigid discharge piping is installed, the line must
be independently supported to avoid vibration and
strain on the pump. For maximum pumping capac-
ity, keep the line as short and straight as possible.
Elbows and fittings used in discharge lines in-
crease friction loss; 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.
