Trane Modular Air Handler M-Series ТЕМ6АОВЗОН

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

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

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

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

Table 19 on page 58 provides bearing set screw torque measurements

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

See 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

Ensure 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

1. To replace throwaway filters, install new filters with the directional arrows pointing in the direction of airflow

Note: Bag and cartridge filters must have an airtight seal to prevent air bypass. If using other than Trane- supplied filters, apply foam gasketing to the vertical edges of the filter. Permanent Filters - Clean permanent filters

1 Disconnect all electrical power to the unit

2 Wash the filter under a stream of water to remove dirt and lint

3 Remove oil from the filter with a wash of mild alkali solution

4 Rinse the filter in clean, hot water and allow to dry

5 Coat both sides of the filter by immersing or spraying it with Air Maze Filter Lote W or an equivalent

6 Allow to drain and dry for about 12 hours

Inspect the unit casing for corrosion. If damage is found, clean and repaint the surface with a rust-resistant primer and vinyl chlorinated lacquer

Clean the fan wheels and fan shaft

Check damper linkages, set screws, and blade adjustment. Clean, but do not lubricate, the nylon damper rod bushings

Inspect electrical components and insulation

Rotate the fan wheel and check for obstructions in the fan housing. The wheel should not rub on the fan housing. Adjust the center if necessary and tighten wheel set screws to the proper torque

Lubricate motor bearings in accordance with motor manufacturer’s recommendations
