Trane Modular Air Handler M-Series TEM4A0C43M41SB

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

Removed the vent and drain plugs

Blown the coil out as completely as possible with compressed air

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

Drained the coil out as completely as possible

Did you replace the vent and drain plugs before putting the coils back into service?

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; and, 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

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

Refer to Table 19 on page 58 for bearing set screw torque measurements

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

Refer to 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

Check if 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

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

Fan sections of air handlers inspected?

Evidence of microbial growth (mold) found?

If evidence of microbial growth (mold) is found, identify and remedy the cause immediately.

All electrical power to the unit disconnected?

Appropriate personal protective equipment worn and any contamination removed?

Section vacuumed 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?

Any contaminated area(s) thoroughly cleaned with a mild bleach and water solution or an EPA-approved sanitizer specifically designed for HVAC use?

Affected surfaces rinsed thoroughly with fresh water and a fresh sponge to prevent potential corrosion of metal surfaces?
