Trane Modular Air Handler M-Series TEM4B0C37M31SA

CAUTION: Coil Freezeup! Properly drain and vent coils when not in use. Trane recommends glycol protection in all possible freezing applications. Use a glycol approved for use with commercial cooling and heating systems and copper tube coils. Failure to do so may result in equipment damage

Flush the coil with glycol if coils will be exposed to temperatures below 35 degrees

Install field-fitted drains and vents to permit winterization of coils not in use and to assist in evacuating air from the water system during startup

If draining is questionable because of dirt or scale deposits inside the coil, fill the coil with glycol before the heating season begins

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.

WARNING: Hazardous Voltage! Disconnect all electric power, including remote disconnects before servicing.

WARNING: Hazardous Chemicals! Handle chemical carefully. Proper handling should include goggles or face shield, chemical resistant gloves, boots, apron or suit as required.

Is the internal insulation clean and dry?

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

If yes, specify the cause of contamination

Was the contamination removed and the affected area sanitized?

If microbial growth on a non-porous insulating surface is observed, was it mechanically removed?

Was the contaminated area cleaned with an EPA-approved sanitizer specifically designed for HVAC use?

Inspect coils for dirt build-up

Disconnect all electrical power to the unit

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

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
