Trane Modular Air Handler M-Series TEM4B0C60S51SA

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

Warning: Disconnect all electrical power to the unit before starting

Dirty filters and block-offs removed

New bag filters slid into the filter rack

Note: The pleats should be in the vertical position

Optional pre-filters replaced on the appropriate filter rack

Fixed block-offs slid into the filter track before the adjustable block-off

Note: The adjustable block-off should always be installed last, next to the access door

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

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. Follow proper lockout/ tagout procedures to ensure the power can not be inadvertently energized.

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.

Is there evidence of microbial growth on the interior insulation?

Is the internal insulation in areas of the unit that are normally considered to be 'dry' 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 (closed cell insulation or sheet metal surface)?

Is the drain line open following the cleaning process?

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