Installation Checklist

The following checklist is only an abbreviated guide to the
detailed installation procedures given in this manual. Use
this list to ensure all necessary procedures are complete.
For more detailed information, refer to the appropriate
sections in this manual.
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 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.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06A-EN
Inspect the unit for shipping damage.
1. Inspect the unit for shipping damage.
2. Level installation location to support the unit
weight adequately. Make all necessary wall or
ceiling openings to allow adequate air flow and
service clearances.
3. Ensure the unit chassis is installed level.
NOTICE:
Unit Leveling!
The unit must be installed level (zero tolerance) in both
horizontal axis for proper operation. Do not use the coil
or drain pan as the reference point because the coil may
be pitched and the drain pan has an inherent positive
slope to provide proper drainage.
4. Verify that wall and ceiling openings are properly
cut per the unit submittals.
5. Verify that installation of horizontal concealed units
meets the national Fire Protection Association
(N.F .P .A.) Standard 90A or 90B concerning the use of
concealed ceiling spaces as return air plenums.
Verify correct ceiling opening dimensions on unit
submittals.
Secure the unit and any accessory items properly to
the wall or ceiling support rods.

6. Complete all piping connections correctly.
7. Check field sweat connections for leaks and tighten
the valve stem packing, and piping package unions
if necessary.
8. Install the auxiliary drain pan, if ordered, properly
under piping package on fan-coil units.
9. Complete condensate drain line connections on
fan-coil units.
10. Pitch condensate drain line away from fan-coil one-
inch drop per ten feet of pipe.
11. Install entering water temperature sensor on the
supply water line, if applicable.
12. Install condensate overflow switch option correctly
on the auxiliary drain pan, if applicable.
13. Ensure the low temperature detection device
option is correctly installed.
14. Complete all necessary duct connections.
15. Complete all interconnection wiring for the wall-
mounted fan mode switch or zone sensor per the
wiring schematic and guidelines established in
"Interconnection Wiring, " p.
16. Install the wall-mounted fan mode switch, or zone
sensor module options properly.
For wireless zone sensors, be sure to set the
address (see "Address Setting, " p.
17. Make field mounted controller / fan speed switch
connections to CSTI / FSS as indicated on unit
schematic.
18. Connect electrical supply power according to the
NEC and unit wiring diagrams.
19. Remove any miscellaneous debris, such as
sheetrock dust, that may have infiltrated the unit
during construction.
20. Replace the air filter as required.
