To complete the installation, the following items
must be considered, which ware not included in the elevator contract :

not to exceed 1/2" at any point. Two-hour fire resistance rating of hoistway walls or
rating to meet applicable local codes.

recesses or setbacks over 2" except on side used for loading or unloading.
3. Number of cars is hoistway, minimum
size of cars, venting and fire rating of doors and entrances must be specified per Model
Building Code.
4. Supports for rail brackets at pit,
each floor and roof. Maximum allowable vertical spacing of rail supports, without backing.

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 hall button boxes, as required.
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 and buffers. Consult Schindler sales representative for rail
forces and buffer impacts. Where space below pit floor can be occupied, consult Schindler
sales representative for special requirements.
9. Convenience outlet and light fixture
in pit with switch located adjacent to access door.
10. Where access to pit is by means of
lowest hoistway entrance, vertical ladder of non-combustible material extending 42'
minimum above sill of access door or handgrips shall be provided to the same height.
11. Free and clear access to elevator pit
area for jack hole drilling rig.
12. Removal of all spoils from jack hole
drilling.
13. Jack hole to accommodate jack unit.
Jack hole to be provided in strict accordance with elevator contractor's shop drawings.
14. For interior application of hydraulic
elevators with front opening and rear glass wall, a minimum 12' high glass enclosure above
bottom landing is recommended for safety. For exterior application, full height glass
enclosure is required.
Machine Room
15. Enclosed and protected machine room.
16. Access to machine room and machinery
space as required by governing code or authority.
17. 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.
18. 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.
19. 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.
20. 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.
21. Cutout through machine room wall,
8"x16", for oil line and wiring duct. Coordinate with Schindler construction
superintendent at building site.
22. Hoisting beams, trap doors, ladders
or stairs and other means of access to machine room for maintenance and equipment removal
purposes.
23. Convenience outlet and telephone
outlet on control panel.
24. All conduit and wire runs remote from
either the machine room or the hoistways.
25. Heat, smoke or products 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
26. Elevator Firefighter's and other
emergency services are required in certain buildings, depending on height of the building
or number of landings.
27. Elevator Firefighter's and other
emergency services' wiring and interconnections to automatic sprinkler systems or heat and
smoke sensing devices furnished by others.
28. When emergency/standby power
operation of elevators is required, the Electrical Contractor should coordinate with your
elevator contractor for operation requirements.
29. Provisions for earthquake protection,
dictated by Model Building Code, are required in various sections of the country. Consult
your elevator contractor for special requirements.
Entrances
30. Hoistway wall are to have a fire
resistance rating in accordance with ASME A17.1 Rule 100.1a.
31. Furnishing, installing and
maintaining the required fire rating of elevator hoistway walls, including the penetration
of fire wall by elevator fixture boxes, is not the responsibility of the elevator
contractor.
32. The interface of the elevator wall
with the hoistway entrance assembly shall be in strict compliance with the elevator
contractor's requirements.
33. 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 12" wide (6"
on each side) and 6" higher than the clear opening (including transom height).
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 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).
34. For applications requiring grouted
sills, provide sill supports with 2½"x4" minimum floor recess the full width of
the hoistway. Grout full length and width after sills are set.
35. Filling and grouting around entrance.
36. The use of 18 gauge (.048")
materials for doors have UL approval.
37. When fixtures are mounted in drywall
side jambs, wall thickness may increase. Requirements must be coordinated with your
