Motor Bearing Lubrication; Fan Motor Inspection; Coils; Steam And Water Coils - Trane Performance Climate Changer Installation, Operation And Maintenance Manual

Routine Maintenance
Refer to
Table 37. Minimum hex head bolt torque in lb.-ft. (Grade 5 bolts)
Note: Soft metric conversions are not acceptable for screw and hex sizes.

Motor Bearing Lubrication

Obtain an IOM from the motor manufacturer for the specific motor installed. The motor
manufacturer's recommendations take precedence for all matters related to the start-up and
routine maintenance of the motor.
Motor grease fittings have been removed from factory-installed motors in compliance with UL
regulations. Motor bearings require periodic maintenance throughout their life. Many different
styles of motors come as standard selections, so please obtain the motor IOM and use the
manufacturer-recommended grease.

Fan Motor Inspection

Inspect fan motors periodically for excessive vibration or temperature.

Coils

All coils should be kept clean to maintain maximum performance.

Steam and Water Coils

Hazardous Chemicals!
Coil cleaning agents can be either acidic or highly alkaline. Handle chemical carefully. Proper
handling should include goggles or face shield, chemical resistant gloves, boots, apron or suit as
required. For personal safety refer to the cleaning agent manufacturer's Materials Safety Data
Sheet and follow all recommended safe handling practices. Failure to follow all safety
instructions could result in death or serious injury.
