Component Installation Requirements
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 equipment
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.
Note:
For additional information regarding the safe discharge of capacitors, see
PROD-SVB06A-EN.
To remove the shipping tie-downs:
1.
Disconnect the power to the unit.
2. Remove the access panels adjacent to the isolators (isolators are at each corner of the fan base)
3. For each isolator, remove the bolt holding it.
4. Remove the pipe or spacer provided with each isolator.
Figure 34. Isolators
Adjusting the Isolators
Once the shipping tie-downs are removed and the internal
isolation is released, it may be necessary to adjust the isolators
to achieve the proper operation height of the fan and motor
isolation base.
Minimum required clearances are listed in
Table 10
. To determine
the isolator clearances on all unit sizes, measure between the top
of the cabinet channel and the bottom of the isolation base
channel.
