TOOLS REQUIRED FOR INSTALLATION:

Before traveling

to the installation site,

be sure you have all

necessary parts and

tools.

TOOLS FOR INSTALLATION

CRE-2100 NRUL 08-16-2004

INSTALLATION

Preparation for Installation

Refer to the rail/clamp chart (supplied) for the correct rail-to-step nosing position.

Note: The information on the installation drawing is intended as a guide for the

installer. Rail placement may vary according to conditions found at the

installation site.

Rails are numbered on the bottom side near the end of the rail. The number indicates

rail placement on the staircase. Box 1-Rail #1 is the first rail at the bottom of the stairs;

Box 2-Rail #2 is the next rail as you go up the stairs, and so on.

Remove the protective ends on each rail section as needed. The hardware securing

these ends are the joint bolts. DO NOT DISCARD.

Attach the lower rail end plate and charge bracket to the lower rail section before

placing the rail on the stairs. See photos below.

Do NOT attach the upper end plate or charge bracket at this time.

INSTALLATION

Clamp Placement and Rail Installation

1. Set the clamps on the steps, as indicated on the Application Drawing.

NOTES: a) The clamp with the longer foot faces the outside (chair side of rail).

b) The foot of the clamps placed on the curves faces inward, and the

rounded head of the clamp attaches to the outside of the rail.

c) Make sure the ridge of the clamp spacer is down (see page 13).

longer foot faces the outside curve clamp: foot to inside

and rounded head to top

2.Referring to the Application Guide, position clamps to ensure correct step nose

clearance.

Note: Before attaching the clamp to the rail, make sure the threaded end of the

bolt is pointing to the inside of the installation (away from the stairs), and

that the longer-footed clamps point toward the outside of the installation

(chair side of the rail).

CRE-2100 NRUL 08-16-2004

INSTALLATION

3. Take special note of the position of the foot and the rounded head of the

curve clamp:

•foot faces inward

•rounded head of clamp attaches to outside surface of rail

(see illustration on previous page).

4. Begin rail placement with the landing section.

•Set the landing section on the staircase.

NOTE: Rail sections are numbered. Place rail no. 1 at the bottom of the

staircase. For spiral case installations, place the no. 1 rail at the

bottom of the stairs.

5. Position and attach the rail clamps to the lower rail assembly as shown on the

installation drawing.

NOTE: Rail clamps vary in size. Verify size and installation location on the

installation drawing.

6. Be sure to verify the step nose-to-rail dimension (measured perpendicular to

the rail bottom).

7. Install the lower rail section to the landing section using (2) M10 x 1.5 x 70 mm

hex head cap screws to join the rails.

NOTE: It may be necessary to install a screw

into one of the rear holes on the clamp

assembly to prevent the rail from sliding.

INSTALLATION

8. Install the remaining lower section(s), if applicable, and add clamps as shown on the

installation drawing.

9. Install the upper rail section(s), adding clamp assemblies with each section.

NOTE: Do not install the end plate and charge bracket at this time.

10. Position the rail as close to the application drawing measurements as possible.

11. Secure the rail with one or two screws.

NOTE: You may need to shim the rail to ensure proper placement. For example,

if the rail is leaning forward, shim the front of the clamp until the unit

is level.

****VERY IMPORTANT****

The degree of slope of the rail is critical. To locate the degree at which each rail piece

should be installed, use the ELEVATION VIEW drawings specific to

your job and inserted in this manual. Place the angle finder on the guide strip on the front

of the rail to obtain the correct angle.

The correct angle should be observed within 1/2 degree, every (2) feet of linear rail travel.

Be sure to check the rail angle every

(2) feet of linear travel.

CRE-2100 NRUL 08-16-2004

INSTALLATION

CLAMP SPACER INSTALLATION

Reminder: When positioning the clamps and mounting the rail on the clamps, make

sure a spacer is inserted between the clamp halves. The rail will

rest on the spacer.

Insert the hardware so that the nut is closest to the wall.

NOTE:

Insert the

hardware

so that the

nut is

closest to

the wall.

NOTE:

When the rail is

inserted between

the clamp halves,

it will rest on the

clamp spacer.

RIDGE OF SPACER

ZERO-DEGREE SLOPE

1. To accomodate the stairways which include a portion with zero-degree slope, Bruno

has included a horizontal adjustment screw on the lower carriage.

NOTE: The horizontal adjustment screw is factory set and should not be

readjusted at the installation site.
