Routine Maintenance
Note: Lubricate the motor bearing according to the motor
manufacturer's recommendations and use the
manufacturer-recommended grease. See the
"Motor Bearing Lubrication" section on page 78.

• Fan bearings without lubrication lines are sealed
bearings. Re-lubrication is not required.
• Fan bearings equipped with lubrication lines should be
lubricated with a lithium-based grease that conforms
to NLGI No. 2 for consistency.

Motor Bearing Lubrication

Obtain an operation and maintenance manual 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. Operating conditions will vary the frequency
of inspection and lubrication. Motor lubrication
instructions are on the motor tag or nameplate. If for some
reason these instructions are not available, contact the
motor manufacturer. Some motor manufacturers may not
provide oil tubes on motors with permanently sealed
bearings.

WARNING
Rotating Components!
The following procedure involves working with rotating
components. Disconnect all electric power, including
remote disconnects before servicing. Follow proper
lockout/ tagout procedures to ensure the power can
not be inadvertently energized. Secure rotor to ensure
rotor cannot freewheel. Failure to secure rotor or
disconnect power before servicing could result in
rotating components cutting and slashing technician
which could result in death or serious injury.
Note: Dirty filters will increase static pressure. The
increase may effect operation of p-trap drain lines.

Throwaway Filters

To replace throwaway filters, install new filters with the
directional arrows pointing in the direction of airflow.
Bag and cartridge filters must have an airtight seal to
prevent air bypass. If using other than Trane-supplied
filters, apply foam gasketing to the vertical edges of the
filter.

Permanent Filters

To clean permanent filters:
1. Disconnect all electrical power to the unit.
2. Wash the filter under a stream of water to remove dirt
and lint.
3. Remove oil from the filter with a wash of mild alkali
solution.
4. Rinse the filter in clean, hot water and allow to dry.
5. Coat both sides of the filter by immersing or spraying
it with Air Maze Filter Kote W or an equivalent.
6. Allow to drain and dry for about 12 hours.
7. Reinstall the filter.
Note: It may be preferable to keep extra, clean filters to
replace the dirty filters to minimize unit downtime
for filter maintenance.
