WARNING:
When installing in a potentially explosive environment, ensure that the motor is properly certi-
fied.
WARNING:
•
Do not test the motor for direction of rotation when it is coupled to the pump. If the pump
is driven in the wrong direction, serious damage to the pump, motor, and personnel could
result.
•
Avoid working under suspended loads. If necessary to do so, follow the more stringent of
local, state or federal safety regulations.
NOTICE:
•
Refer to the separate IOM supplement for thrust pots.
•
Failure to disconnect and lock out driver power may result in serious physical injury or
death. Always disconnect and lock out power to the driver before performing any installa-
tion or maintenance tasks.
•
Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
•
Refer to driver/coupling/gear manufacturer's installation and operation manuals
(IOM) for specific instructions and recommendations.
1.
If a driver support is furnished and not installed, perform these steps:
a) Hoist the driver support and inspect the mounting surfaces and register.
b) Clean these surfaces thoroughly.
c)
Install the driver support on the discharge head and secure it with capscrews.
2.
Attach a sling to the lifting lugs of the driver and hoist the motor.
3.
Inspect the mounting surface, register, and shaft extension, and then clean these surfaces thor-
oughly.
If any burrs are found, remove them with a smooth mill file.
4.
Orient the motor-conduit box in the required position:
a) Align the motor-mounting holes with the mating-tapped holes on the discharge head.
b) Lower the motor until the registers engage and the motor rests on the discharge head.
c)
Secure the motor with capscrews.
5.
On drivers with a non-reverse ratchet or pins, manually turn the driver shaft clockwise when viewed
from the top, until the non-reverse ratchet or pins fully engage.
6.
Lubricate the motor bearings according to the instructions on the lubrication plate attached to the
motor frame.
7.
Make temporary electrical connections according to the tagged leads or the diagram attached to the
motor.
The motor must rotate clockwise when viewed from the top. See the arrow on the pump nameplate.
If the motor does not rotate clockwise, change the rotation by interchanging any two leads (for
three-phase only). For single-phase motors, see the instructions from the motor manufacturer.
If motor shaft-end-play adjustment is required, check it using a dial indicator before you connect the
pump coupling to the solid shaft motor. Consult the applicable motor manufacturer instruction man-
ual for detailed information on motor end play.
