Air Filters

WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious injury.
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 a
CAT III or IV voltmeter rated per NFPA 70E that all
capacitors have discharged.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06*-EN.
Filter access doors are shared with the evaporator cassette
access door. To replace throwaway filters, remove the dirty
elements and install new filters with the filter's directional
arrows pointing toward the fan. Verify that no air bypasses
the filters. See Figure 47, p. 61
