Frequency
Maintenance
After 48 hours 
of operation
Belts have acquired their permanent set. Readjust but do not overtighten. See the “Tension the Fan Belt” section on 
page 45 for more information.
Every week
Observe unit weekly for any change in running condition and unusual noise.
Every month
• Clean or replace air filters if clogged or dirty; coat permanent filters with oil after cleaning. See the “Air Filters” section 
on page 49 for more information.
• Relubricate fan bearings if necessary. See the “Fan Bearing Lubrication” section on page 51 for more information.
• Check and adjust fan belt tension.
Every three to 
six months
• Check fan bearing grease line connections. Lines should be tight to the bearings.
• Check bearing and motor bracket bolt torque and bearing setscrew torque.
• Align fan and motor sheaves. Tighten sheave set screws to the proper torque. See the “Sheave Alignment” section on 
page 47 for more information.
• Inspect and clean drain pans. See the “Drain Pans” section on page 50 for more information.
• Tighten electrical connections.
• Inspect coils for dirt build-up. See the “Coils” section on page 52 for more information.
Every year
• Inspect the unit casing for corrosion. If damage is found, clean and repaint the surface with a rust-resistant primer 
and vinyl chlorinated lacquer.
• Clean the fan wheels and fan shaft. See the “Fans” section on page 50 for more information.
• Inspect and clean drain pans.
• Check damper linkages, set screws, and blade adjustment. Clean, but do not lubricate, the nylon damper rod 
bushings.
• Clean damper operators.
• Inspect electrical components and insulation.
• Inspect wiring for damage.
• Rotate the fan wheel and check for obstructions in the fan housing. The wheel should not rub on the fan housing. 
Adjust the center if necessary and tighten wheel set screws to the proper torque.
• Lubricate motor bearings in accordance with motor manufacturer’s recommendations (see the “Fan Bearing 
Lubrication” section on page 51 for more information).
• Check condition of gasketing and insulation around unit, door and dampers.
• Examine flex connections for cracks or leaks. Repair or replace damaged material.
 WARNING
Hazardous Service 
Procedures!
The maintenance and 
troubleshooting procedures 
recommended in this section of the 
manual could result in exposure to 
electrical, mechanical or other 
potential safety hazards. Always 
refer to the safety warnings provided 
throughout this manual concerning 
these procedures. When possible, 
disconnect all electrical power 
including remote disconnects before 
servicing. Follow proper lockout/
tagout procedures to ensure the 
power can not be inadvertently 
energized. 
For variable frequency drives or 
other energy storing components 
provided by Trane or others, refer to 
the appropriate manufacturer’s 
literature for allowable waiting 
periods for discharge of capacitors. 
Verify with an appropriate voltmeter 
that all capacitors have discharged. 
When servicing fans or ductwork, 
secure the impeller to physically 
restrict rotational movement. When 
necessary to work with live 
electrical components, have a 
qualified licensed electrician or 
other individual who has been 
trained in handling live electrical 
components perform these tasks. 
Failure to follow all of the 
recommended safety warnings 
provided, could result in death or 
serious injury
