Electric Motor Driven Pumps
Allow only qualied personnel to INSTALL, WIRE and
OPERATE electric motor driven pumps. Whenever
electricity is present there is the possibility of
electrocution.
NEVER use a pump/motor in an explosive atmosphere
if it is not exclusively designed for the application.
Always ground electrical units.
Make certain to connect pump motor to the right phase
and voltage.
Do not run pump if voltage is not within limits.
Make sure motor rotation is in accordance with
impeller rotation (which should be indicated somewhere
on the pump — check the manufacturer’s manual).
Make all electrical installations in accordance with
National Electric Code, State and Local electrical codes.
Never use gas piping as an electrical ground.
Make sure the related electrical circuits are dead and
locked out before performing any maintenance.
Follow motor manufacturer’s recommended
maintenance and operation instructions.
If circuit breaker or fuse is tripped, examine the
system for the problem before restarting pump.
NEVER use the power cord to aid lifting the pump.
NEVER operate a pump with a plug-in type power cord
without a ground fault circuit interrupter.
NEVER use cords with frayed, cut or brittle insulation.
Check the cord on the pump for nicks in the insulation
and for sound connections to the ground fault
interrupter plug and motor.
NEVER let extension cords or the plug connections lay
in water. Locate the pump so that the cord cannot fall
into any water or be submerged by rising water, unless
the pump is designed for such use.
NEVER handle energized power cords with wet hands.
MOTOR OVERLOAD: do not exceed the manufacturer’s
recommendation for maximum lift or discharge head.
See manufacturer’s published curve for proper sizing of
motors. A misapplied motor can overheat.

Submersibles
Allow only qualified personnel to INSTALL, WIRE and
OPERATE submersible pumps.
Whenever electricity is present there is the possibility of
electrocution.
NEVER use a pump/motor in an explosive atmosphere,
if it is not exclusively designed for that application.
ALWAYS ground the pump.
Make certain to connect the pump to the right
phase and voltage.
DO NOT run the pump if voltage is not within limits.
Make all electrical installations in accordance with
National Electric Code, State and Local electrical
codes.
Mount electrical control box in a vertical position,
protected from the elements.
NEVER use the power cord
or hydraulic hoses to lift or
lower submersibles. Attach
a lifting cable to the
manufacturer’s
recommended attachment
point on the pump for
lowering and lifting the
pump.
NEVER position the pump directly on a sift, loose bot-
tom. To attain maximum capacity and prevent exces-
sive wear, position the pump so it will not burrow itself
into sand or clay. Stand the pump on a plank, a bed of
coarse gravel, within a perforated container, on a suit-
able floatation device, or retain it hanging freely by a
lifting cable.
