Trane Modular Air Handler M-Series TEM4A0C43M41SB

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

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

Flush old grease from bearing with suitable solvent

Amount of grease in the bearing chamber (should be three-quarters full)

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

CAUTION: Microbial Growth! 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.

WARNING: Hazardous Voltage! 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: Hazardous Chemicals! Coil cleaning agents can be either acidic or highly alkaline. Handle chemical carefully. Proper handling should include goggles or face shield, chemical resistant gloves, boots, apron or suit as required. For personal safety refer to the cleaning agent manufacturer's Materials Safety Data Sheet and follow all recommended safe handling practices. Failure to follow all safety instructions could result in death or serious injury.

Is the internal insulation clean and dry?

Is there evidence of contamination in either the wet or dry sections?

Is there microbial growth on a non-porous insulating surface?

Is the drain line open following the cleaning process?

Is the unit dry thoroughly before putting it back into service?

Are all panels and parts replaced and electrical power restored to the unit?

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

WARNING: Hazardous Pressures! Coils contain refrigerant under pressure. When cleaning coils, maintain coil cleaning solution temperature under 150°F to avoid excessive pressure in the coil. Failure to follow these safety precautions could result in coil bursting, which could result in death or serious injury.

Disconnect all electrical power to the unit

Wearing the appropriate personal protective equipment, use a soft brush to remove loose debris from both sides of the coil

Install a block-off to prevent spray from going through the coil and into a dry section of the unit and/or system ductwork

Mix a high-quality coil cleaning detergent with water according to the manufacturer’s instructions

Place the mixed solution in a garden pump-up sprayer or high-pressure sprayer

Maintain minimum nozzle spray angle of 15 degrees

Spray perpendicular to the coil face

Keep the nozzle at least 6 inches from the coil

Type K cooling coils have removable headers for cleaning every three to six months

Note: Apply washers under the bolt heads. Bolts should be evenly tightened to 50 foot-pounds of torque, beginning in the center and working toward the outside
