INSTALLATION

OVERVIEW

OVERVIEW OF INSTALLATION

Installation of the ELECTRA-RIDE™ LT Stairway Elevator consists of the following:

* Determine whether the elevator should be a left- or right-side installation. "Left"

or "right" installation is determined by the side of the stairway on which the rail is installed (viewed from the bottom of the stairs). THE GEAR RACK WILL BE TOWARD THE CENTER OF THE STAIRS. Unless specified otherwise, Bruno Stairway Elevators are set up for left-side installation when shipped, but can easily be converted to right-side installation. Instructions for converting the unit for right-hand installation are included later in this manual.

* Identify and locate lower rail section and bumper bracket assembly.

* Assemble and tighten the rail joint. CAUTION: RAILS CANNOT BE MIXED.

CHECK ID NUMBERS STAMPED AT ENDS OF RAILS.

* Determine the correct length for the rail (using Steps 2 & 4 from the APPLICATION

GUIDE), and cut the rail.

* Install lower bumper assembly.

* Position rail on left or right side of stairway using rail clamp assemblies.

* Mount the carriage on the upper rail.

* Adjust the carriage angle by loosening the (2) Angle Adjustment Bolts.

* Install seat assembly and make electrical connections.

* When installing a right-side ELECTRA-RIDE™ LT , follow instructions for Changing to Right-Hand Operation

* Perform a 5-6 trial runs of the ELECTRA-RIDE™ LT to determine final location of

the rail.

INSTALLATION

OVERVIEW

OVERVIEW (CON'T.)

* Determine the appropriate location for the remaining mounting clamps and

brackets for attaching the rail to the stairs then loosely assemble the clamps and brackets to the Stairway Elevator rail.

* Adjust and tighten the rail clamps and mounting brackets.

* Anchor the mounting brackets to the stairs.

* Locate and drill holes for the top bumper bracket.

* Install the top bumper bracket.

* Determine where the power supply will be positioned, and install rail wire lead

accordingly.

* Position power supply at upper or lower landing.

* Route wire to household outlet.

* Mount remote call/send transmitters.

* Test unit for proper operation.

* Train customer in safe and convenient operation of the Stairway Elevator.

REMEMBER:

No installation is complete until the customer has been trained to use the Elevator smoothly and safely. After demonstrating correct operation, have the customer operate the Elevator several times while you are available to answer questions.

BE SURE THE CUSTOMER UNDERSTANDS ALL SAFETY ASPECTS OF USING THE ELEVATOR. Patience and thoroughness in this phase of the

installation are often rewarded with repeat business and customer referrals.

INSTALLATION

ASSEMBLY

1) Determine whether a left- or right-side installation is appropriate for the site. "Left" or "right" refers to the side of the stairway on which the rail is installed (as viewed from the bottom of the stairs). Unless otherwise specified Bruno Stairway Elevators are shipped from the factory in the left-side configuration. Conversion to right-side installation is easy (instructions included later in this manual ).

2) Identify and locate lower rail section appropriate to the installation (left or right).

BUMPER BRACKET INSTALLATION

1) Assemble lower rail.

2) Install lower bumper bracket.

bumper bracket

FITTING THE RAIL

1) Determine the correct length for the rail by measuring along a straight line placed on the stairs. (SEE STEP 2 IN THE APPLICATION GUIDE) To that amount, add Measurement B (STEP 4 IN THE APPLICATION GUIDE). This process will allow you to custom fit the Elevator to your customer by determining the most comfortable seat-to-floor height within the space available at the top of the stairs.

NOTE: The rail must rest approximately 2" above the step nosing, and extend from the lower floor to a point beyond the nosing of the top step (see Step No. 4 of the Application Guide). In some cases where the bottom landing is made of material such as concrete, ceramic tile or slate, the last bracket on the landing may be omitted. In this case, a bracket must be added on the second-to-last step ( bottom), and

at the top of the stairway.

REMINDER:

THIS RAIL MUST BE INSTALLED APPROXIMATELY 2" ABOVE STAIR NOSING.

OTHERWISE, FOOTREST WILL HIT THE STEPS, CAUSING INTERMITTENT

OPERATION.

CUTTING THE RAIL

IMPORTANT NOTE!

Under no circumstances should a rail section be cut shorter than

18” (46 cm).

There must be at least (2) clamps on a short rail section (1 at the rail

joint and 1 at the rail end). Cutting a rail shorter than 18” (46 cm)

would not allow enough room for the (2) necessary clamps.

Example:

After measuring the staircase, you determine you need 9 feet of rail.

With your (2) 8-foot sections you decide to use (1) 8-foot section and cut the remaining (1) foot from the second 8-foot section. Doing this

could yield a rail piece with insufficient weld.

Instead, Bruno recommends cutting at least one foot off one of the

8-foot sections (leaving 7 feet of rail) and then cutting 2 feet from the

second 8-foot section. You will have a (1) 7-foot section and (1) 2-foot

section, both of which are long enough to be properly mounted

(2 clamps minimum per short rail).

NEVER CUT OFF THE JOINT END!

The M6 bolts securing the gear rack must remain intact.

Cut off the end with the pre-drilled charge contact mounting holes.

Then, using the provided template, redrill (2) holes on each end of the rail.

1) Use a metal-cutting power saw or manual hacksaw to cut the rail to length. Cut off the end of the rail to be located at the top of the stairway.

2) Use a file or other appropriate tool to deburr the cut end of the rail. Soften any sharp edges which might abrade the insulation of the wiring to

be routed to the bumper at the end of the rail.

use “O” size drill bit

(8.03mm/.316")

SRE-2700 06-11-2004

3) Use a C-clamp to hold the upper bumper bracket in place at the cut end of the rail. Use the holes in the bumper bracket as guides to drill mounting holes in the rail using an“O” size (8.03 mm/.316") drill bit.

INSTALLATION

RAIL JOINT ASSEMBLY

NOTE:

The rail is always installed

with the gear rack towards the

center of the stairs and gear

teeth facing the wall.

INSTALLATION SUGGESTION

1) Assemble the rail joint by attaching the bottom plate to the rail with the screws, lock washers and hex nuts provided with the unit. Install the bolts, internal-tooth washers and hex nuts through the joint blocks on both sides of the rail. Tighten all bolts securely and make sure screw heads are flush with the surface of the inside of the rail. PLEASE REFER TO EXPLODED VIEWS AT

BACK OF MANUAL.

Once two sections of rail

are installed, and before

installing the carriage, run a

plomb line along the rail. If

the rail bows, insert shims

or readjust clamps.

NOTE:

The chamfered

edges of the

holes must face

"up" toward

the bottom of

the rail.

SRE-2700 06-11-2004

POSITIONING FOOT CLAMP ASSEMBLIES

1) Place rail mounting foot clamps in the pattern as indicated.

clamp placement order

INSTALLATION

Be sure to leave a minimum space of 4"*, as measured from the back edge of the rail to the wall.

•bottom landing

•first tread up from bottom landing

•top landing

•first tread down from top landing

•closest tread above and below the rail joint(s)

•minimum of every third tread over remainder of staircase.

*The 4" clearance is needed if the seat is

to swivel 90 degrees. For installations

where the seat will swivel less than 90 degrees, the rail-to-wall clearance may be reduced to between 3" and 3-1/2". Frequently check the seat-wall clearance during installation.

Note: If top or bottom clamp is omitted because the landing is cement or ceramic tile, or in the event that the owner wishes not to drill holes in the landing, a set of clamps should be added on the second-to-last step and at the top of stairway.

SRE-2700 06-11-2004

INSTALLATION

INSTALLATION ON CARPET

Before securing the foot clamp

assemblies with hardware, seat them

using a deadblow hammer. Use a

rubber mallet to compress the rug and

pad before anchoring the clamp.

2) For ease of installation, finger tighten all clamp assemblies to rail. The clamp

assembly should be positioned so the nut is closest to the wall.

3) Slide top and bottom clamps down on the rail until firmly seated on step. When installing on carpeted stairs, use a rubber mallet on the clamps to compress carpet and pad before anchoring to steps.

4) Drill in one screw in the foot nearest the wall of each of the top and bottom of foot of clamp assemblies.

This will enable the installer to change the position of the rail if necessary and minimize the number of holes drilled in the wrong location.

Bruno recommends installing the screws in the

back clamp (the one closer to the wall) first,

then the screws in the front of the clamp.

foot clamp assembly

*Install foot clamps at least 2-1/2” from wall (approx. 4" between the back

edge of the rail and the wall). Provide additional foot clamp-to-wall

clearance if seat needs to swivel against wall.

INSTALLATION NOTES

For installations on hardwood

stairs, Bruno recommends

drilling a pilot hole before

inserting fasteners.

5) Frequently check the measurements at the key locations indicated to ensure proper positioning

of the clamp assemblies.

*see note below

If threaded fastener

extends below a stair

tread that is exposed, it

can be trimmed flush

with pliers.

Bruno ships the Stairway

Elevator with fasteners

appropriate for

wooden stair treads only.
