Review instructions before operating.
WARNING - ELECTRICAL PRECAUTIONS
All wiring, electrical connections, and system grounding must comply
with the National Electrical Code (NEC) and with any local codes
and ordinances. Employ a licensed electrician. For non-thermally
protected motors use with approved motor control that matches
motor input in full load amperes with overload element(s) selected
or adjusted in accordance with control instructions.
This pump is suitable for installations where the vertical distance
from the pump to the water level does not exceed 25 ft. In all
Model No.

PUMP LOCATION: The pump should be installed in a clean, dry
and ventilated location which provides adequate drainage and room
for servicing and protection from freezing temperatures. It should
be bolted down evenly on a good foundation, preferably concrete,
to prevent the development of unnecessary stress. Locating the
pump as close as possible to the source of water supply reduces
the friction losses in the suction pipe and provides for maximum
capacities.
SUCTION PIPE: It is recommended that only new clean pipe or
hose be used and the size be the same as that of the pump suction
tapping. If the pump is installed any appreciable distance away from
the source of water supply, the suction pipe should be increased
by one size. The suction pipe must always slope upwards from
the water source to the pump to avoid air pockets in the line. In
cases where the pump has to be reprimed often and it is not nec-
essary that a lot of water be delivered, it is advisable to use a 90°
or 45° elbow on the suction line. This enables the pump to prime
sooner and also prevents kinking of the hose. In cases where a
maximum volume of water is required over a prolonged period of
time, the suction line should be led almost horizontally to the pump.

WARNING - RISK OF ELECTRICAL SHOCK
•
Have an electrician provide electrical power to the motor.
•
Motor must be grounded and terminal cover in place to
reduce electrical shock hazard.
•
Keep motor operating area as dry as possible.
•
A ground fault interrupter (GFI) protected circuit is recommended
for use with any electrical device operating near water.
•
Always disconnect power before servicing.
•
Not investigated for use in swimming pool areas.
APPLICATION
installations, friction losses in the suction pipe must be taken into
consideration.

Non-toxic thread compound should be used on all pipe joints and
connections should be thoroughly tightened. A strainer should be
connected to the bottom end of the suction pipe and it should be
well submerged at all times.
WARNING - RISK OF ELECTRICAL SHOCK

WIRING: Make sure the voltage and frequency of the power
supply agrees with that stamped on the motor nameplate. If
in doubt, check with the power company.
WARNING - ELECTRICAL PRECAUTIONS
All wiring, electrical connections, and system grounding must
comply with the National Electrical Code (NEC) and with any local
codes and ordinances. Employ a licensed electrician.
SINGLE PHASE: Determine incoming voltage to motor. Where
possible, use 230V. Connect wiring to terminal board located inside
motor end cover. Be sure voltage connections agree with wiring
diagram on motor nameplate.
THREE PHASE: Three Phase motors require magnetic starters,
and can run in either direction, depending on how they are con-
nected to the power supply.
