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 recom-
mended for use with any electrical device operating near water.
•
Always disconnect power before servicing.
•
Not investigated for use in swimming pool areas.
SAFETY WARNINGS
BEFORE OPERATING OR
INSTALLING THIS PUMP, READ
THIS MANUAL AND FOLLOW
ALL SAFETY RULES AND
OPERATING INSTRUCTIONS.
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.
SAFETY
CAUTION
•
DO NOT OPERATE THIS PUMP DRY!
•
Review instructions before operating.
CAREFULLY READ THESE SAFETY
MESSAGES IN THIS MANUAL AND ON PUMP.
APPLICATION
This pump is suitable for installations where the vertical distance
from the pump to the water level does not exceed 25 ft. In all
installations, friction losses in the suction pipe must be taken into
consideration.

PERFORMANCE
INSTALLATION
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 necessary 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 pro-
