Trane Modular Air Handler M-Series ТЕМ6АОВЗОН

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

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

CAUTION: Bearing Failure! Do not mix greases with different bases within the bearing. Mixing grease within the bearing may result in premature bearing failure

Table 19 on page 58 provides bearing set screw torque measurements

Ensure the grease used in electric motor bearings is not mixed with the grease used in fan bearings

See Table 21 for compatible greases and Table 22 for maximum grease capacity

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

Refer to Table 23 for minimum torque of motor mounting and bearings bolts

Ensure fan bearings without lubrication lines are sealed bearings

Ensure fan bearings equipped with lubrication lines are lubricated with a lithium-based grease that conforms to NLGI No. 2 for consistency

The process of cooling and dehumidification produces condensate that must be continuously removed from the air-handling unit. The section of the unit from the entering air side of the cooling coil to the leaving edge of the drain pan is considered to be the "wet" section of the unit. Other potentially "wet" sections are immediately downstream of a humidifier and/or an outside air intake section

Wet interior unit insulation can become an amplification site for microbial growth (mold), which may cause odors and damage to the equipment and building materials. If there is evidence of microbial growth on the interior insulation, the insulation should be removed and replaced prior to operating the system

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/ tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury

Warning: Ensure to wear appropriate PPE during the cleaning process.

Tubes cleaned with a nylon or wire brush if fouled?

Note: Do not replace the header covers until the coils are put back into service to ensure no water remains in the coil.

New gaskets used when the coils are put back into service?

Enter the torque applied to the bolts (ft-lbs)
