Routine Maintenance

Air Filters

Refer to product catalog CLCH-PRC003-EN for filter sizes, types, and quantities.

￿WARNING Hazardous Voltage with Capacitors!

Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before servicing. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. For variable frequency drives or other energy storing components provided by Trane or others, refer to the appropriate manufacturer’s literature for allowable waiting periods for discharge of capacitors. Verify with an appropriate voltmeter that all capacitors have discharged. Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury.

Note: For additional information regarding the safe discharge of capacitors, see PROD-SVB06A-EN.

Throwaway Filters

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

To clean permanent filters:

1Disconnect all electrical power to the unit.

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

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

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

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

6Allow to drain and dry for about 12 hours.

7Reinstall the filter.

Note: It may be preferable to keep extra, clean filters to replace the dirty filters to minimize unit downtime for filter maintenance.

Front Load Filters

Most filters in custom units are installed in unitary sheet metal frames. Filters are secured with a metal clip. There are several different styles.

To install filters:

1Disconnect power to the unit.

2Open or remove the filter clip.

3Remove the filter from the rack.

4Install new filters with the directional arrows pointing in the direction of airflow.

5Secure the filter using the appropriate clip for each filter.

The filters are often installed in a pre/post filter configuration. Be sure to note the order of installation.

Note: Filters must have an airtight seal to prevent air bypass.

Side Load Filters

Most filters in custom units are installed in unitary sheet metal frames. If unit is provided with side access rack, do the following for installation:

2-inch or 4-inch flat filters

1Disconnect the power to the unit.

2Open the filter section access door and remove the filters and block-offs from their installed position.

3Slide the filter into the rack.

4Some side load racks will be provided with block-off plates. Install them into the rack last before closing the door.

5Close and secure the door, making certain the door closes snug against the block-off.

Bag or Cartridge Filters

1Disconnect power to the unit.

2Keeping the bag filters folded, slide each filter into the filter rack, pushing them tightly against the unit. Pleats should be in the vertical position.

3If using optional pre-filters, slide them into the appropriate filter rack.

4If block-offs are provided with the unit, slide the block-offs into the filter track.

5Close and secure the access door, making certain the door closes snug against the rack.

Note: The block-off is intended to make a seal when the access door is closed. It may require a few adjustments to ensure a proper seal.
