Trane Modular Air Handler M-Series TEM4B0C60S51SA

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

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

Fan belt tension checked three times during the first days of operation?

CAUTION: Belt Tension! Do not over-tension belts. Excessive belt tension will reduce fan and motor bearing life, accelerate belt wear and possibly cause shaft failure. Under tensioning belts is the primary cause of premature belt failure. Belts should not squeal at startup.

Belt tension rechecked after 8 hours, 24 hours, and 100 hours of operation and monthly thereafter?

Proper belt tension ensured based on motor horsepower requirement?

If the drive is changed from the original, proper belt tension estimated?

Correct operation tension for a V-belt drive ensured?

Unit observed weekly for any change in running condition and unusual noise?

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.

Disconnect all electrical power to the unit

Wearing the appropriate personal protective equipment, remove any contamination

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

Thoroughly clean any contaminated area(s) with a mild bleach and water solution or an EPA-approved sanitizer specifically designed for HVAC use

Immediately rinse the affected surfaces thoroughly with fresh water and a fresh sponge to prevent potential corrosion of metal surfaces

Allow the unit to dry completely before putting it back into service

Be careful any contaminated material does not contact other areas of the unit or building. Properly dispose of all contaminated materials and cleaning solution

Inspect fan motors periodically for excessive vibration or temperature

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

Enter the torque applied to the bolts
