Control Dampers
If the damper actuators are not factory mounted install
damper actuators and connecting linkage. Check damper
operation and linkage alignment.
Damper blades should be non-binding. Adjust damper
frame as necessary to ensure free blade movement.
Filters
Front-Load Filters
Most filters in custom units are installed in sheet metal
frames. Filters are secured with a metal clip. There are
several different styles.
To install filters:
1. Disconnect power to the unit.
2. Open or remove the filter clip.
3. Remove the filter from the rack.
4. Install new filters with the directional arrows pointing
in the direction of airflow.
5. Secure the filter using the appropriate clip for each
filter.
Review Figure 32 through Figure 35 for an explanation of
the methods for securing the different types of filters.
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.
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 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.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06A-EN
