Left side or right side?
"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 specied Bruno Stairway Elevators are
shipped from the factory in the left-side conguration.
Conversion to right-side installation is easy (instructions
included later in this manual ).
1. Identify and locate lower rail section appropriate to the
installation (left or right).
FITTING THE RAIL
1. Determine the correct length for the rail by measuring
along a straight line placed on the stairs. (SEE STEP 4
IN THE APPLICATION GUIDE).
To that amount, add Measurement B (STEP 4 IN THE
APPLICATION GUIDE).
This process will allow you to custom t the Elevator
to your customer by determining the most comfortable
seat-to-oor height within the space available at the top
of the stairs.
NOTE: The rail must rest approximately 2" (5 cm) above
the step nosing, and extend from the lower oor
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.
ASSEMBLY
INSTALLATION
The standard stairway
elevator is suitable for
stairway angles up to
45 degrees.
