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

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.

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.

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.

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.

INSTALLATION NOTES

INSTALLATION

TESTING THE UNIT

1) Before securing, all clamps and with the seat in the central riding position, use the rocker switch to run carriage/seat assembly completely down and up the rail. Observe the seat-to-wall clearance.

Direction of travel of

the seat/carriage

corresponds to the

side of the rocker

switch depressed.

A slight delay will

occur between the

time the rocker

switch is depressed

and the initiation of

carriage

movement. This is

normal and is a

function of the soft

start feature of the

controller.

The unit should travel

noticeably faster going

up than down.

A clearance of 1/2" to 1" is acceptable.

2) Repeat the run with the seat in the folded position. If

necessary, adjust the rail placement by sliding it closer to, or further from the wall.

3) Make a total of 5 or 6 trial runs to be sure all components

are functioning correctly, and that proper seat-to-wall clearance is maintained over the entire length of travel.

These 5-6 runs will also help clean paint chips out of the gear rack which can be vacuumed or brushed away (see Lubrication section).

4) Once the rail position is determined, place one screw in the back foot of each clamp assembly to hold the rail in place while securing the foot clamp assemblies. Placing this one screw will also help prevent the clamp foot from rotating while tightening the screws.

ALWAYS PARK THE CARRIAGE AT THE

UPPER OR LOWER END OF THE RAIL TO KEEP

SRE-2700 06-11-2004

5) Tighten the bolts securing the foot clamp assemblies to the rail.

6) Install and tighten the screws in the remaining foot clamps (back clamp first, then front clamp).

7) Check tightness of all screws/bolts.

8) Run the carriage/seat assembly up and down the rail to recheck the seat-to-wall clearance, and to verify correct operation of all elevator components.

INSTALLATION

INFRARED CALL/SEND TRANSMITTER

The call/send system on the Bruno SRE-2700 is based on infrared (IR) controls, the same type of control used for televisions and stereos.

Like a television remote, the SRE-2700 hand-held transmitter may experience certain types of interference. Receivers are mounted on both sides of the SRE-2700 carriage to minimize intereference.

Should interference occur, the unit will stop. This feature has been integrated into the SRE-2700 to ensure your safety.

The direct line between the transmitter to either of the (2) transmitters should be clear of obstacles for optimal operation.

To reduce the possibility of interference:

• while riding in the seat, ALWAYS operate the Elevator using the rocker switch on the armrest.

Operating the SRE-2700 with a transmitter while riding in the seat can lead to signal interference.

• DO NOT mount the transmitters behind an obstacle such as a rail post.

• DO NOT allow direct sunlight to shine on the receivers (blinding the receivers on the carriage).

• DO replace transmitter batteries regularly.

Depleted or nearly-depleted batteries alter the effective range of the transmitter.

• DO keep the transmitter and receiver lens free of dirt and debris.

Use a non-abrasive cleaner suitable for glass or acrylic surfaces. Do not use polishes or cleaning products containing wax. These products

will leave a film on the lens that will reduce the signal transmission range.

LEARNING THE REMOTE INFRARED TRANSMITTER

(not necessary when installing unit for the first time)R

The operating channel of the two (2) infrared transmitters included with the SRE-2700 is pre-set at the Bruno factory.

Should it become necessary to re-learn the transmitters (for example, if there are multiple units in the same location, or in the event you have to replace tranmitters) proceed as follows:

1) Turn off the circuit breaker.

2) On the CARRIAGE COVER, locate and remove the 3/4" black plug (center top of the carriage approximately half-way between the two white infrared receivers). Please refer to the photo to the left.

3) Look through the hole in the carriage cover and locate the RED BUTTON on the circuit board.

REVERSING OPERATION (for right-hand installation)

As shipped from the factory, the Elevator is set up for left-hand installation (as viewed from the bottom of the stairs.)

In the field, however, should the dealer/installer need to convert the Elevator from left-hand to righthand operation, follow the instructions given below.

Note that it is not necessary to change the rocker switch when converting to a right-hand installation. Only in the event that the user does not have use of his/her right hand would moving the rocker switch to the left armrest be necessary.

Instructions for changing the rocker switch from the right armrest to the left armrest immediately follow the instructions for converting the circuit board for right-hand operation.

To convert the rail/carriage for right-hand operation:

1) Remove the 3/4" black plug (b) located in the center top of the carriage (approx. half-way between the two white infrared receivers).

CIRCUIT BREAKER

circuit breaker with

on/off switch built in

ELECTRICAL

The on/off switch is built into the circuit breaker which is provided to protect the battery, controller and motor circuits in the Elevator carriage. It is unlikely that this circuit breaker will ever “trip” during normal use, but if the Elevator should fail to operate, check the circuit breaker and reset it if necessary. If the circuit breaker should trip, determine the cause and correct the situation.

The most likely cause of a tripped circuit breaker would be a foreign object jamming the rail or gear rack or overloading the elevator by exceeding its rated load capacity.

LONG-TERM STORAGE

TURNING THE UNIT OFF

When the Elevator will not be in use for an extended period of time:

1) move the seat/carriage 2"-3" away from the lower charge contacts,

2) turn off the circuit breaker, then

3) unplug the power supply from the wall outlet.

DO NOT unplug the power supply from the wall outlet without first turning off the circuit breaker. Failure to first turn off the circuit breaker will result in battery discharge or premature battery failure.

TURNING THE UNIT ON

To turn the Elevator back on:

1) turn on the circuit breaker, then

2) plug the power supply back into the wall outlet.

NOTE: The batteries may require recharging before normal use if the Elevator has remained in the `off ' position for an extended period of time. To do so, simply move the unit to the LOWER charge contacts, and reconnect the power supply to the wall outlet (circuit breaker `on').

Check circuit breaker, reset if necessary.

Check battery connections.

Check footrest safety switches to see if one of these limit switches is depressed. Sliding safety tray below footrest should slide freely and should not stick in a position which would depress one of the safety switches.

Check for discharged batteries. Battery voltage should be in a range of 21-29 VDC. Unit will "cut out" at 16.5V and will require 21V to restart.

Check for discharged batteries.

Check for loose connections.

Check to make sure power supply is plugged in and working.
