Trane Modular Air Handler M-Series TEM6A0B24H

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

Check damper linkages, set screws, and blade adjustment. Clean, but do not lubricate, the nylon damper rod bushings

Inspect electrical components and insulation

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

Warning: Use care in removing header plugs from Type P2, P4, and P8 coils. Over-torquing may result in twisted tubes

Remove the vent and drain plugs

Blow the coil out as completely as possible with compressed air

Fill and drain the coil several times with full strength glycol so that it mixes thoroughly with the water retained in the coil

Drain the coil out as completely as possible

To ensure no water remains in the coil, do not replace the vent and drain plugs until the coils are put back into service

WARNING: Hazardous Voltage! Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/ tagout procedure to ensure the power cannot be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury

Motor bearings are factory-lubricated for normal life

In the case of a double-shielded bearing, the grease provided is that which is in the bearing

To regrease motors without grease fittings, remove the bearing brackets

If the original bearing is to be relubricated, remove the shield opposite the rotor

Flush old grease from bearing with suitable solvent

Lubricate the bearing and add grease to the bearing chamber

The chamber should be three-quarters full of grease

Lubricate the bearing according to the motor manufacturer's recommendations and use the manufacturer-recommended grease

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.

WARNING: 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 drive sheaves to ensure rotor cannot freewheel.

Clean or replace air filters if clogged or dirty

Coat permanent filters with oil after cleaning

Change bag filters when pressure drop is 1 in. wg

Relubricate fan bearings if necessary

Check and adjust fan belt tension

Sign off on the monthly air handler maintenance

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

Inspect coils for dirt build-up
