Assemble the track, with cable
pulley as shown in Figure 5.2.4.
The curve must align and butt
up against the vertical track
snugly.
Before bracing the horizontal
tracks, ensure that they are
square to the opening and level.
To check whether your diagonals
are equal:
a) Measure from the top of the
vertical track to the end of
the horizontal track.
b) Check both sides.
c) Adjust if necessary.
The
track
support
must
located along the horizontal
track approximately at
3
/
height. For doors higher than
2280mm
and/or
wider
4700mm two supports will be
required.
d) Calculate the horizontal track brace position as per
section 1.4.2.
e) Measure along the horizontal track to the desired position
and find a structurally sound location to fix your support
to the ceiling or side wall.
f) Each installation must be assessed individually for ceiling
fixing requirements.
g) Lift the torsion bar assembly into position, resting on top
of the tracks.
h) Connect the side bearing brackets to the end of the
horizontal tracks using 3/8" and 1
bolts and 3/8" washers and nuts. Fig 5.2.4.
i) Slide the torsion bar

one side bearing bracket and then the other.
j) Place the cable drums into position after a washer, noting
that red cable drum with red spring and black cable
drum with black spring. DO NOT tighten screws yet.
k) Secure the spring anchor bracket
foundation directly or thorugh the use of a steel angle to
timber beams onto the ceiling, ensuring the 'cut corner'
is pointing in the direction of the opened door.
Unwind the lifting cable from the
tip
bottom panel.
l) Thread the lifting cable around the sheave pulley wheel
and over to the rear cable drums. Fig 5.2.5.
m) Attach the lifting cable to the cable drum
the cable into the slot on the outside groove. (the ferrule
will prevent the cable from coming out).
n) Wind the cable by hand by turning the cable drum away
from the door.
o) Once the cable is taut, slide the cable drum
the side bearing bracket and tighten the screws to the
torsion bar. Fig 5.2.6. Refer to section 3.7 for spring tension.
