SETTING AND ALIGNING THE MOTOR ASSEMBLY:
(See Fig. 1.) The motor is mounted on a tripod. Set the tripod over the floor hole; position the universal
shafting to the motor coupling, set and shim the motor assembly so that it is level and the shafting
alignment below is maintained.
IMPORTANT:
The motor must support the weight of the line shafting. The motor coupling half should be installed in a fixed
position to carry the weight of the line shaft (see page 1). You will note that the coupling half has been
provided with two setscrews located at 180' apart. One setscrew is directly over the keyway and locks the
key in place. The other setscrew MUST seat itself firmly into the motor shaft.
CONTROLS:
Different kinds of motors may be used depending upon size or service of a pump and the electrical currents
available at the pump location. Since motors may be direct current or single or three-phase alternating
current, they may vary considerably according to the system of winding employed, and are specific as to
current requirements; a discussion of controls covering all types would be lengthy and is therefore not
attempted.
WIRING:
Connect the electric service to the controls and make inter-control electrical connections according to wiring
instructions accompanying the switches and motor, using conduit and wire sizes as required by local power
companies. Be certain current characteristics of voltage and frequency indicated on the motor nameplate
are the same as service provided.
ROTATION:
Check rotation of the motor, see that it turns in the direction indicated by the rotation arrow on pump casing;
if incorrect refer to motor manufacturer's instructions for reversing.
FUSE RECOMMENDATIONS:
Be certain fuses are installed and comply in size with the National Electric Code and Local Code
recommendations.
