![© 1998 BRUNO INDEPENDENT LIVING AIDS, INC.6INSTALLATIONASSEMBLYFIGURE 1FITTING THE RAIL[ ] Determine whether the elevator should be a left or rightside installation. "Left" or "right" installation is determinedby the side of the stairway on which the rail is installed(viewed from the bottom of the stairs). Unless specifiedotherwise Bruno Stairway Elevators are set up for left sideinstallation as shipped, and can easily be converted to right sideinstallation (instructions included in this manual on page 15).[ ] Identify and locate lower rail section for the left or rightinstallation.BUMPER BRACKET INSTALLATION[ ] Assemble lower rail, install Bumper Bracket.[ ] Determine the correct length for the Rail by measuringalong a straight line placed on the stairs. (SEE STEP 2 INTHE APPLICATION GUIDE) Add to that amountmeasurement B (STEP 4 IN THE APPLICATION GUIDE). Thisprocess will allow you to custom fit the elevator to yourcustomer taking into consideration the most comfortableseat to floor height within the space available at the top ofthe stairs.NOTE: THE RAIL MUST REST APPROXIMATELY 1/2" TO 1" ABOVENOSING OF THE STEPS AND EXTEND FROM THE LOWERFLOOR TO A POINT BEYOND THE NOSING OF THE TOP STEP(SEE APPLICATION GUIDE STEP 4). IN SOME CASES WHERETHE BOTTOM LANDING IS MADE OF MATERIAL SUCH AS(CONCRETE, CERAMIC TILE OR SLATE) THE LAST BRACKET ONTHE LANDING MAY BE OMITTED WITH A BRACKET ADDED ONTHE SECOND STEP FROM THE BOTTOM AND TOP OF STAIR-WAY.BUMPER BRACKETCAUTION:THIS RAIL MUST BEINSTALLED 1/2" TO 1"ABOVE NOSING OFSTAIRS, OR THEFOOTREST WILL HITTHE STEPS CAUSINGINTERMITTENTOPERATION.](https://usermanual.wiki/Bruno-Independent-Living-Aids/PCB4950.Updates-PDF-Users-Manual/User-Guide-8821-Page-6.png)
![© 1998 BRUNO INDEPENDENT LIVING AIDS, INC.7INSTALLATIONCUTTING THE RAIL[ ] Use a metal-cutting power-saw or manual hacksaw to cutthe rail to length. Cut off the end of the rail which will be located atthe top of the stairway.[ ] Use a file or other appropriate tool to de-burr the cut end ofthe rail. Soften any sharp edges which might abrade theinsulation from wiring which must be routed to the bumper at theend of the rail.[ ] Use a C-clamp to hold the upper Bumper Bracket in place inthe cut end of the rail and use the holes in the Bumper Bracketas guides to drill mounting holes using “O” size (8.03 MM/.316")drill bit in the rail.[ ] Assemble the Rail joint by attaching the Bottom Plate toRail with M6 X 20 Flat Head Screws, external-tooth Lockwashers and M6 Hex Nuts. Install the M10 Bolts, M10 internaltooth Washer and M10 hex nut through the Joint Blocks on bothsides of the Rail. Tighten all bolts securely and make sure screwheads are flush with the surface of the inside of the Rail.NOTE:THE CHAMFERED EDGES OF THEHOLES MUST FACE "UP" TOWARDTHE BOTTOM OF THE RAIL.FIGURE 2FIGURE 3NOTE:THE RAIL IS ALWAYSINSTALLED WITH THEGEAR RACK TOWARDSTHE CENTER OF THESTAIRS AND GEAR TEETHFACING REAR OF UNIT.RAIL JOINT ASSEMBLYUSE “O” SIZE DRILLBIT (8.03MM/.316")](https://usermanual.wiki/Bruno-Independent-Living-Aids/PCB4950.Updates-PDF-Users-Manual/User-Guide-8821-Page-7.png)

(See figure 4 & 5)[ ] Slide top and bottom clamps down until firmly seated onstep. When installing on carpeted stairs a rubber malletshould be used on clamps to compress carpet and cushionbefore anchoring to steps.[ ] Install securely one screw near the wall on top and bottomof foot of clamp assemblies. This will enable the installerto change position of the rail if necessary and preventdrilling excess holes.POSITION RAIL CLAMP ASSEMBLIESINSTALLATIONFIGURE 4*NOTE:CHECK ARM WIDTHREQUIRED BYCUSTOMER.

Confirmcorrect operation of this feature by moving the sliding tray(BOTH SIDES) while operating the elevator. The elevatorwill stop if this feature is operating correctly.The Carriage comes equipped with a Safety Switch Panel.As the Carriage approaches the end of the Rail, the Panel isdepressed, which activates the Switch, and stops the carriage.FIGURE 10INSTALLATIONSAFETY SWITCHFOOTRESTSAFETY SWITCHNOTE:MAKE SURECALL/SEND ANTENNAHAS CLEARANCE FORENTIRE TRAVEL OFRAIL.

Be sure that this wiring is mountedsecurely so that it is not vulnerable to physical damage.[ ] Coil any excess harness wire and attach to a Rail Clamp(under the rail).NOTE: THE CHARGER SHOULD BE PLUGGED INTO AHOUSEHOLD OUTLET ALL OF THE TIME. THE ELEVATOR ISDESIGNED SO THAT THE BATTERIES WILL BE CHARGEDWHEN THE CARRIAGE IS AT ONE OR THE OTHER END OFTHE RAIL. IT IS IMPERATIVE THAT THE CARRIAGE BE"PARKED" AT THE END OF THE RAIL WHEN IT IS NOT IN USETO MAINTAIN FULL BATTERY CHARGE.IN AN INSTALLATION WHERE THE CARRIAGE CAN NOT BEPARKED AT THE END OF THE RAIL (STAIRWAYS WITH ADOOR AT THE TOP, FOR EXAMPLE), THE CARRIAGESHOULD BE RUN TO THE OTHER END OF THE RAIL WITHTHE REMOTE CALL/SEND MODULE WHEN NOT IN USE.THIS WILL ENSURE THAT THE BATTERIES WILL REMAINFULLY CHARGED.FIGURE 17SUGGESTION:AFTER ROUTING THEWIRE HARNESS OUT OFSIGHT A SMALL PIECEOF DOUBLE SIDEDFOAM TAPE CAN BEAPPLIED TO THEHARNESS PLUGS ANDATTACH UNDER THERAIL.NOTE: IF CHARGER PLUG ANDWIRE ARE LOCATED INA VULNERABLELOCATION, A PLUGLOCK TO PREVENTACCIDENTALUNPLUGGING ISRECOMMENDED.THESE ARE AVAILABLEAT HARDWARE ANDDEPARTMENT STORES.RAIL CHARGER LEADLEAD TO BATTERYCHARGER WIRINGHARNESSROUTING WIRE HARNESSESINSTALLATION](https://usermanual.wiki/Bruno-Independent-Living-Aids/PCB4950.Updates-PDF-Users-Manual/User-Guide-8821-Page-20.png)

![© 1998 BRUNO INDEPENDENT LIVING AIDS, INC.26A Circuit Breaker is built into the on/off switch and is provided toprotect the Battery / Controller / Motor circuits in the ElevatorCarriage. It is unlikely that this Circuit Breaker will ever “trip” innormal use, but if the Elevator should fail to operate, check theCircuit Breaker and reset it if necessary. If the Circuit Breakershould trip, determine the cause and correct the situation.The most likely cause of a tripped Circuit Breaker would be aforeign object jamming the Rail or Gear Rack or overloading theelevator by exceeding its rated load capacity.A Fuse has been provided to protect the Battery Charging circuitand the Call / Send electronics. The Elevator is shipped with thisFuse installed.[ ] Turn “OFF” the unit using the “ON” / “OFF” switch on the backof the unit.[ ] Disconnect the Battery Charger from the Rail ChargeLead.[ ] Remove carriage cover.[ ] Determine and repair any short circuit which may havecaused the fuse to blow.FUSE AND CIRCUIT BREAKERFIGURE 23ON/OFF SWITCH WITH CIRCUITBREAKER BUILT INCIRCUIT BREAKERTO REPLACE A "BLOWN" FUSE:](https://usermanual.wiki/Bruno-Independent-Living-Aids/PCB4950.Updates-PDF-Users-Manual/User-Guide-8821-Page-26.png)

![© 1998 BRUNO INDEPENDENT LIVING AIDS, INC.28TURNING THE UNIT ONVACATION / LONG TERM STORAGEIf the elevator will not be in use for and extended period of time theunit should be moved 2"-3" away from the lower Charge contactsand the red circuit breaker should be turned off. After the elevatoris in this position, the charger should be unplugged from the walloutlet.DO NOT unplug the charger from the wall outlet unless the circuitbreaker has been turned off. This will result in battery discharge orpremature battery failure.[ ] To turn the unit back on , turn the circuit breaker on, plug thecharger back into the wall outlet.NOTE: The batteries may need to be recharged beforenormal use if the elevator was in the `off ' position for anextended period of time. To do so , simply move the unit tothe LOWER charge contacts, and re-connect the charger tothe wall outlet (circuit breaker `on').](https://usermanual.wiki/Bruno-Independent-Living-Aids/PCB4950.Updates-PDF-Users-Manual/User-Guide-8821-Page-28.png)

The cam may be reset by rotating the cam back to itsdetent position. By bypassing the overspeed switch andrunning the drive unit up, the cam can be rotated in by hand.[ ] Should a failure occur which would activate the overspeed,the complete drive unit will have to be removed from the railand returned to the dealer or the manufacture to determinethe reason for the failure. Repairs would then have to becompleted before unit could be used again.[ ] Install call/send lock boxes as shown below. The keyswitch should be approximately 42" from floor. One boxshould be installed at the top of the stairs and one at thebottom.RESETTING OVERSPEEDFIGURE 24MOUNTING CALL/SEND LOCK BOXNOTE:INSTALLATION OFCALL/SEND MAY VARYBY LOCAL CODE.PLEASE REFER TOLOCAL CODES FORINSTALLATION GUIDE-LINES.THE SEAT KEY SWITCHAND ROCKER SWITCHARE LOCATED UNDERTHE RIGHT ARM PAD.(ON YOUR RIGHT ASYOU ARE SITTING INTHE SEAT.)
