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! 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. 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.
!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.
CAUTION
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 openins 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 pkg unions if necessary.
!8. Install the auxiliary drain pan properly under piping package on fan- coil units.
!9. Complete condensate drain line connections on
!10. Pitch condensate drain line away from
!11. Install automatic changeover sensor option on the supply water line, if applicable.
!12. Install automatic electric heat lockout switch option on the supply water line, if applicable.
!13. Install condensate overflow switch option correctly on the auxiliary drain pan, if applicable.
!14. Ensure the low temperature detection device option is correctly installed.
!15. Complete all necessary duct connections.
!16. Complete all interconnection wiring for the wall mounted fan mode switch or zone sensor per the wiring schematic and guidelines established in the “Wall Mounted Control Interconnection Wiring” section.
!17. Install the wall mounted fan mode switch, or zone sensor module options properly.
!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.
