Trane Modular Air Handler M-Series TEM6A0C42H

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

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?

Inspect coils for dirt build-up

Dirty filters and block-offs removed from their installed position

New bag filters slid into the filter rack, pushed tightly against the unit

Door can be closed without compressing the filter

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
