For specific rules, refer to ASME A17.1, Part III or CAN/CSA-B44 for hydraulic elevators. Local requirements must be used if more stringent.

Items To Be Provided
To complete the installation, the following items must be considered, which are not included in the elevator contract:

Hoistway

2. 75° bevel guards on all projections, recesses or setbacks over 2" (51mm) ASME A17.1 or 100mm CAN/CSA-B44 except on side used for loading or unloading.

3. Number of cars in hoistway, minimum size of cars, venting and fire rating of doors and entrances must be specified per applicable Building Code.

4. Supports for rail brackets at pit, each floor and roof. Maximum allowable vertical spacing of rail supports, without backing. Divider beams between hoistway at each floor and roof, for guide rail bracket supports.

5. Light outlet for each elevator, in center of hoistway, pit and machine room, as indicated by your elevator contractor.

6. Recesses, supports, and patching, as required, to  accommodate wall mounted hall button boxes, signal fixtures, etc.

7. All barricades either outside elevator hoistways or between elevators inside hoistways as required.

8. Dry pit reinforced to sustain normal vertical forces from rails, jack units and buffers. Pit to be level and free of debris at jack unit locations. Consult Schindler sales representative for rail forces, jack loads and buffer impacts. Where space below pit floor can be occupied, consult Schindler sales representative for special requirements.

9. Convenience outlet and light fixer in pit with switch located adjacent to access door per ASME A17.1 Rule 106.1e and CAN/CSA-B44 2.7.5.

10. Where access to pit is by means of lowest hoistway entrance, vertical ladder of non-minimum above still of access door or handgrips shall be provided to the same height.

11. Coordinate sump hole location in pit with Schindler representative to avoid interference with jack unit location.

Machine Room.

12. Enclosed and protected machine room.

13. Access to machine room and machinery space as required by governing code or authority.

14. Lighting, convenience outlets, heating, cooling and ventilation of machine room and machinery space. Machine room temperature to be maintained between 55° F and 90° F (13° and 32°C). Relative humidity to be maintained at 95% or less non-condensing.

15. A fused disconnect switch for each elevator and light switch located per National Electrical Code, (NFPA No.70), and where practicable, located inside machine room adjacent to door.

16. Suitable copper feeder, ground and branch wiring circuits for signal system and power operated door, including main line switch. Feeder and branch wiring circuits for car light and fan, including main line switch. Ground fault protection as required by NEC 620-85.

17. Clear access above ceiling, or metal/concrete raceways in floor, for oil line and wiring duct from machine room, if  machine room is remote from elevator hoistway.

18. Cutout through machine room wall, 8" x 16" (203mm x 406mm), for oil line and wiring duct. Coordinate with Schindler construction superintendent at building site.

19. Hoisting beams, trap doors, ladders or stairs and other means of access to machine room for maintenance and equipment removal purposes.

20. Convenience outlet and telephone outlet on control panel.

21. All conduit and wire runs remote from either the machine room, or the hoistways.

22. Heat, smoke or producers of combustion sensing devices connected to elevator machine room terminals when such devices are required. Make contacts on the sensors should be sized for 120 volt D.C.

Emergency Provisions

23. Elevator Firefighter's and other emergency services are required in certain buildings, depending on height of the building or number of landings.

24. Elevator Firefighter's Service is required per ASME A 17.1 Rule 211.3 and may be required per CAN/CSA-B44 3.12.15.1.1. Elevator Firefighter's Service wiring and interconnections to automatic sprinkler systems or heat and smoke sensing devices furnished by others. Emergency services may be required by Building Code.

25. Provisions for earthquake protection, dictated by the Building Codes, may be required Consult your elevator contractor for special requirements.

Entrances

26. Hoistway walls are to have a fire resistance rating in accordance with ASME A17.1 Rule 100.1a.

27. Furnishing, installing and maintaining the required fire rating of elevator hoistwaty walls, including the penetration of fire wall by elevator fixture boxes, is not the responsibility of the elevator contractor.

28. The interface of the elevator wall with the hoistway entrance assembly shall be in strict compliance with the elevator contractor's requirements.

29. Entrance wall and finished floor are not to be constructed until after door frames and sills are in place.
a. Where front walls are of reinforced concrete, the concrete openings must be minimum 9" (229mm) wide on each side and 9" (229mm) higher than the clear opening.
b. Where drywall or sheet rock construction is used for front walls, it shall be of sufficient strength to maintain the doors in true lateral alignment. Drywall contractor to coordinate with the elevator contractor,

Note: A support member (spreader beam) must be provided for floor heights greater than 12'-0" (3658mm) to support entrance header struts.

c. Door frames are to be anchored to walls and properly grouted in place to maintain legal fire rating (masonry construction).

30. Filling and grouting around entrance.

31. The use of 18 gauge (.048") materials for doors have UL approval.

32. When fixtures are mounted in drywall side jambs, wall thickness may increase. Requirements must be coordinated with your elevator contractor.

33. Where openings occur, all walls and sill supports must be plumb.

34. When sill supports are provided by the elevator manufacturer, hoistway should be capable of accepting anchor stud type fasteners.

35. When fluted steel decking is used under concrete flooring, the concrete must be no less than 4" (102mm) thick; 21/2"(64mm) thick for sill angle anchors.
