Trane Modular Air Handler M-Series TEM6A0C36H

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

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

Failure to secure drive sheaves or disconnect power before servicing could result in death or serious injury

Fan sections of air handlers should be inspected every six months at a minimum or more frequently if operating experience dictates. If evidence of microbial growth (mold) is found, identify and remedy the cause immediately

1. Disconnect all electrical power to the unit

2. Wearing the appropriate personal protective equipment, remove any contamination

3. Vacuum the section with a vacuum device that uses high- efficiency particulate arrestance (HEPA) filters with a minimum efficiency of 99.97 percent at 0.3 micron particle size

Open any variable-air-volume terminals connected to the air handler

Operate the supply fan for 10 to 15 minutes

Rotate inlet guide vanes full open to full close

Note: Air movement discourages water condensation and hastens re-evaporation of any condensate that does happen to form. This simple preventative measure effectively combats microbial growth and curbs moisture-related deterioration of air-handling components.

Sign off on the air handler maintenance

Remove all vent and drain plugs

Allow the water to drain from the coil

If tubes are fouled, clean the tubes with a nylon or wire brush

To ensure no water remains in the coil, do not replace the header covers until the coils are put back into service

Note: When the coils are put back into service, use new gaskets. Trane recommends washers be used under the bolt heads and bolts be evenly tightened to 50 ft-lbs torque

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
