ment could result in injury or death to
personnel.
The pump may 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 the in­
stallation 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.
Positioning the Pump (Stand Application)
Secure a discharge hose to the pump discharge
connection, and use a suitable lifting device at­
tached to the lifting handle to lower the pump into
the wet well. The recommended maximum sub­
mergence depth is 65 feet.
Make certain that the pump and stand sit level in
the wet well.
Reel in any slack control cable so that it is not
dragged into the pump suction.
Piping
The optional discharge elbow/baseplate is drilled
for connection to a discharge flange for slide rail
applications. Either hose or rigid pipe may be used
to make discharge connections.
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.
Field Wiring Connections (Incoming Power)
Do not connect the pump motor directly
to the incoming power lines. The pump
motor is designed to operate through a
control box which provides overload
protection and power control; other­
wise, the pump warranty will be voided.
Make certain that the pump and control
box are properly grounded, and that the
incoming power matches the require­
ments of the pump and controls. Install
and operate the control box in accor­
dance with the National Electric Code
and all local codes. Failure to follow
these could result in injury or death to
personnel.
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
