Start-Up
Motor-Related Checks
• Locate installation manual from the motor manufacturer for the specific motor installed. This
can be found by contacting the motor manufacturer’s representative. The motor
manufacturer’s recommendations take precedence for all matters related to the start-up and
routine maintenance of the motor.
• Check the motor lubrication for moisture and rust.
– Remove and clean grease plugs to inspect.
– If moisture is present, consult an authorized repair shop for bearing inspection/replacement.
This may require removal and transport of motor.
– If no moisture is present, refer to the motor manufacturer’s lubrication recommendations for
proper lubrication.
– The motor manufacturer may recommend lubricating the motor as part of their routine start-
up instructions.
• Check motor winding. An acceptable winding resistance reading is from 6 meg-ohms to infinity.
If reading is less than 5 mega-ohms, the winding should be dried out in an oven or by a blower.
• Inspect the entire motor for rust and corrosion.
• Bump-start the unit and confirm the fan wheel rotates properly, as indicated by the rotation
arrow located on the fan housing.
Note: For motor warranty needs, contact your local Trane sales office.
