2.8Checklist for Completed Installation

___ 1. Unpack and check received material.

___ 2. Proper clearance for service access has been maintained around the equipment.

___ 3. Equipment is level and mounting fasteners are tight.

___ 4. Piping completed to refrigerant or coolant loop (if required). Piping has been leak checked, evacuated and charged (if required).

___ 5. Check piping within the Liebert Challenger ITR and outside of the unit. Remove potential of rub-through or chaffing.

___ 6. Condensate pump installed.

___ 7. Drain line connected.

___ 8. Water supply line connected to humidifier (if required).

___ 9. Field provided pan with drain installed under all ceiling mounted fluid condensing units (if installed).

___ 10. Ducting completed (if applicable).

___ 11. Filter(s) installed.

___ 12. Line voltage to power wiring matches equipment serial tag.

___ 13. Power wiring connections completed between disconnect switch, evaporator and condensing unit, including earth ground.

___ 14. Power line circuit breakers or fuses have proper ratings for equipment installed.

___ 15. Control wiring connections completed to evaporator and condensing unit.

___ 16. Verify water detection is properly installed around all units (if installed).

___ 17. All wiring connections are tight.

___ 18. Control panel DIP switches set based on customer requirements.

___ 19. Foreign materials have been removed from, in and around all equipment installed (literature, shipping materials, construction materials, tools, etc.).

___ 20. Fans and blowers rotate freely.
