Installation - Mechanical

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.

Magnahelic Air Filter Gage

Check zero adjustment of the gage. Turn both vent valves to the “Vent” position and adjust the gage

pointer to zero by means of the external adjustment screw in the face of the gage. After zeroing,

turn the vent valves to the “Line” position.

 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.

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:

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 44 through Figure 47 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.
