SAFETY INSTRUCTIONS
WARNING: General Precautions
o Review all the instructions before operating. Failure
to follow these instructions could cause bodily
injury and/or property damage.
o Though this pump is warranted to handle abrasives,
pumping sand continuously shortens the life of
the pump and motor and adversely affects their
performance. To prevent the above from occurring,
the pump and motor should be installed in fully
developed wells having the proper well screening
to prevent the pumping of abrasives.
o The pump and motor are water cooled and
lubricated, and should be sized and used in a
well that will provide adequate capacity to prevent
running dry. The pump is designed to run dry for
intermittent periods, but the motor is not.
o The pump, piping, and system must be protected
against freezing temperatures.
o Wear gloves and eye protection during assembly
and installation as precautionary safety measures.
o Never use in swimming pools or pool areas.
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.
o A ground fault interrupter (GFI) protected circuit is
recommended for use with any electrical device
operating near water.
o Have a qualified electrician provide electrical power
to the motor. For cable sizes see Table 1.
o Make sure the line voltage and frequency of the
electrical current supply match the specifications
printed on the motor.
o Be sure leads and ground wires are properly water-
proofed and securely connected.
o Ensure the motor is properly grounded.
o Always disconnect the power before servicing.
o Never test a pump or use outside a well without
proper electrical grounding of the system.
Table 1 - (American) Cable selection
Based on a 5% Voltage drop
(Service entrance to motor - Maximum length in feet)
CAUTION: Use of smaller than recommended cable sizes
voids motor warranty!
Table 1 - (Canadian) Cable selection
Based on a 3% Voltage drop
(Service entrance to motor - Maximum length in feet)
CAUTION: Use of smaller than recommended cable sizes
voids motor warranty!
