Air Filters

WARNING
Rotating Components!
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. 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.

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 filters not supplied by
Trane, apply foam gasketing to the vertical edges of
the filter.

Coils

All coils should be kept clean to maintain maximum
performance.
