Electrical supply MUST match
pump's nameplate specifications. In-
correct voltage can cause fire, damage
motor and void the warranty.
Motors without built-in protection MUST be provided
with contactors and thermal overloads for single phase
motors, or starters with heaters for three phase motors.
See motor nameplate.
• Use only copper wire to motor and ground. The ground
wire MUST be at least as large as the wire to the motor.
Wires should be color coded for ease of maintenance.

• Model 3756 S-group has greased for life bearings.
No regreasing is possible or necessary.
• Model 3756 M or L-group bearing frame and SAE drive
bearing frame should be regreased every 2,000 hours or
at a three month interval, whichever occurs first. Use a #2
