The Seat Assembly
The Seat Assembly (Fig.8) includes
the seat chassis and plastic moldings, upholstered pads (where fitted),
folding seat base and armrests, one of which incorporates the manual
controls (toggle switch) and diagnostic status lights (Light Emitting
Diodes) and the seat swivel lever.
The seat assembly now needs to be fixed to the
seat post on the carriage. If not already in place, fit the seat swivel
index plate cover by simply sliding it over the seat post, so that the
seat swivel micro-switch is visible through the small circular hole in
the cover. Position the seat so that it faces across the staircase and
the seat post locates in the off-set ‘ring’ in the underside of the seat
chassis.
To properly locate the seat assembly onto the
seat post, fold the armrests and seat base into the upright position and
work the seat back and forth whilst applying gentle downward pressure.
At the same time depress the seat swivel lever, (Fig.9).
Connect the seat/carriage control lead, by
pushing the two pieces of the connector together and securing with the
screw collar, fitted to the connector attached to the seat assembly (Fig.10).
Next, locate the red plug on the top of the
carriage marked "Battery Isolation" and insert in it's socket. Locate
the key, fitted to the underside of the seat arm and turn to the "Go"
position and the stair lift will become operational (though by battery
power only).
Note: The
stair lift will only be operational if the seat is locked in the riding
position (i.e. facing across the stairway) and the green LED is
illuminated. If the yellow LED is illuminated the seat swivel lever
should be depressed and the seat turned, so that it is locked in the
riding position.
Using the toggle switch in the direction of
travel, move the lift 3 or 4 steps down the staircase. There will be a
safety delay of approx 3 seconds, before the stair-lift begins to move.
Remove the red battery isolation plug to silence the audible "battery
not charging" warning.
Installing Upper Charge Point
If dealing with a "stock length" rail, the
upper charge point now needs to be installed. Otherwise, skip to section
entitled, ‘Connecting the Transformer’,
If not already installed, determine where the
upper charge point will be attached. This is accomplished by running the
stair lift carriage to the top of the staircase and stopping it at the
point where the carriage footrest is level with the top step. The charge
point should be positioned on the side of the rail so that it is in
contact with the spring-loaded charging pins, fitted to the inside of
the carriage chassis. (Fig.11)
Mark the position with a pencil or scribe. Also
at this time, position and mark where the upper stopping limit ramp will
be fixed to the top of the rail, so that the ‘finger’ of the ramp
contacts and activates the top limit micro-switch that is fitted to the
underside of the stair lift carriage assembly (the right-hand switch,
when viewed down the rail). (Fig.12)
With optimum adjustment, the stair lift should
park at the top of the stairs with the footrest adjacent to the top
step, however, the footrest edge should not come into contact with the
top stair nose. (Fig.13)
Drive the stair lift to the bottom of the
staircase. Fix the upper stopping limit ramp to the top of the rail,
using one of the self-tapping screws, provided in the kit. (Fig.14)
If not already drilled and using the upper
charge point as a template, drill two 2mm pilot holes to mount the
charge point on the side of the rail, in its’ correct position.
Pass the spur cable back down the inside of the
rail and out through the ½ inch hole drilled in the side of the upper
rail section. Connect the brown wire to the uppermost charge strip and
the blue wire to the lowermost charge strip (Fig.15), Fix
the charge point to the rail with two of the self-tapping screws
provided in the kit.
Connecting the Transformer
The plug-in transformer that is supplied may
have a male connector plug attached. If so, cut the male connector plug
off with wire cutters and discard. Separate the two wires and strip back
the plastic sheath on each wire, exposing ¼ inch of copper wire.
Connect the transformer wires to the connector
block, so that the blue rail wires oppose the black transformer wire and
the brown rail wires oppose the black/gray transformer wire (Fig.16)
Finally, tuck the connector block and loose
wiring into the inside of the upper rail section, so that only the
transformer wires protrude from the upper end of the rail and snap the
rail-end cover into position.
With the plug-in transformer connected to the
mains supply, the rail charge points are now energized with a safe 15
volts AC.
Fixing to Staircase
The entire assembly now needs to be fixed to
the staircase. Move the rail as close to the edge of the staircase as
possible - but ensuring that the seat back does not come into contact
with the wall.
Note: Care
must be taken to allow for any protrusions, such as windowsills, water
pipes, central heating radiators etc.
Make sure that the rail is equidistant from the
staircase stringer at the top and bottom steps. When you are completely
satisfied that the lift carriage and seat assemblies are able to travel
the entire length of the rail, unhindered by any obstruction, screw the
stair brackets to the stair treads, through the carpet (if fitted),
using the 16 wood screws provided.
Note: A
minimum distance of 1/2" should be maintained between the back of the
seat assembly and the stairway wall.
Fix the safety edge molding to the ‘down’ side
of the carriage body. Locate the stand-off screw threads in the holes in
the carriage chassis (Fig.17).
WARNING! It is essential that the carriage
safety edge molding is fitted, as failure to do so could put the user at
risk of personal injury.
Attach the safety edge molding to the stand-off
screws, using the two cross head type screws provided. (Fig.18/19).
Finally, where local codes dictate, affix the
remote control handsets to the wall at the head and foot of the
stairway. To do this, remove the battery cover and the PP9 battery from
the handset and using the two screws and wall-plugs provided, fix the
handset to the wall so that the three infra-red bulbs are pointing
upwards, towards the ceiling.
Note: The
Infra-red signal works by ‘line of sight’. Therefore the remote control
must have a clear "view" of the stair lift carriage that it commands.
The signal does have the ability to bounce off walls and
ceilings, so the remote control does not have to be pointed directly at
the stair lift - however, for optimum performance, the remote controls
should be mounted, where they are visible from the stair lift.
This completes the
installation. |
