or death to personnel can result from
any alteration to the cable.
Control Box Installation
The pump is designed to be operated
through the control box furnished with
the pump. The control box provides
overload protection and power control.
Do not connect the pump motor directly
to the incoming power lines.
The control box is a rainproof enclosure with a pad
lockable front cover.
The enclosure is not de
signed to be watertight, and should not be sub
merged.
Refer to the control box manual for enclo
sure dimensions and parts.
Secure the control vertically on a level surface,
above flood level. The box should be easily acces
sible to the operator, and located close enough to
the pump to avoid excessive voltage drop due to
cable length (see
Pump Power Cable Connec
tion
). After the box is installed, make certain the
front cover latches properly.
Failure to mount the control box vertically
on a level surface may affect operation of
the pump controls.
Dual Voltage Usage
Some pumps are powered by a dual‐voltage motor
for utilization with high or low voltage. The motor
was originally wired and shipped from the factory
for use with the voltage indicated as “Factory
Wired” on the pump's name plate. The name plate
also indicates the dual voltage pertaining to this
motor. If the alternate voltage must be utilized, con
trol box modifications and/or certain wiring
changes are required.
The control box assembly provided with this pump
has been designed to accommodate
only
the volt
age indicated on the front of the box. This voltage
coincides with the “Factory Wired” voltage of the
motor. If the alternate voltage is utilized, the control
box must be replaced with another box designed
for the appropriate voltage. Alternate voltage con
trol boxes are shown in the Parts List Manual under
Pump Options.
Dual voltage pumps are wired at the fac
tory only for the voltage shown on the
name plate. Make certain that the con
trol box voltage matches the pump volt
age before using. If the pump voltage is
changed, the pump name plate must be
changed and a new control box must be
installed. Do not run the pump if the volt
ages do not match; otherwise, the pump
warranty will be negated, and damage
to the pump, and injury or death to per
sonnel can result.
The motor wiring
must also
be changed before uti
lizing alternate voltage. For detailed instructions on
disassembly and reassembly of the terminal hous
ing, see
Terminal Housing and Power Cable Dis
assembly
and
Terminal Housing and Power
Cable Reassembly
in the Maintenance And Re
pair manual. Change the motor leads as indicated
on the wiring diagram plate affixed to the side of the
terminal housing (see Figure B-2).
Be sure
to tag
the revised voltage on the pump.
