WARNING
Rotating Components!
Failure to secure rotor or disconnect power before
servicing could result in rotating components cutting
and slashing technician which could result in death or
serious injury. The following procedure involves
working with 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 rotor to ensure rotor cannot freewheel.
Throwaway Filters
To replace throwaway filters, install new filters with the
directional arrows pointing in the direction of airflow.

prevent air bypass. If using filters not supplied by
Trane, apply foam gasketing to the vertical edges of the
filter.
