WARNING:
The opener must be securely
fastened to structural supports, otherwise opener
failure may ensue causing serious personal injury
and/or property damage.
Step 4 - Determine Bracket Position
Open the door and fi nd the highest point of travel of
the top door panel.
Using a level, transfer this height to the wall above
the door
(Fig. 16)
and mark a line 60mm above it.
Determine the centre point on the wall above and on
top of the door. Draw two lines extending 21.5mm
from each side of the centre point.
(Fig. 17)
Step 5 - Mounting the Wall Bracket
Centre the bracket over the intersection of these two
lines. Mark centres for at least two holes
(Fig. 17)
.
Ensure this is into a solid mounting point
Drill holes into the wall with an appropriate bit.
Secure to the wall using:
IF CONCRETE OR BRICK - 8mm (5/6”) loxins/dynabolts.
IF TIMBER - wood screw #20 or similar (min. 50mm).
WARNING:
Make sure concrete, brick wall or
timber lintels are solid and sound so as to form a
secure mounting platform.
Step 6 - Attach the Rail to the Wall Bracket
Attach the C-Rail assembly to the wall bracket
with the 90mm long clevis pin and secure with the
supplied snap pin
(Fig. 18)
Leave the powerhead in its packing box for protection
during installation.
Step 7 - Secure the Powerhead to the Ceiling
Raise the powerhead from the packing box and
support it in the horizontal position with a step
ladder or with a similar rigid object.
Open the garage door. Rest the opener on the open
door and use a scrap piece of wood to bring it to
horizontal level.
Line up the track perpendicular to the wall.
Secure the perforated angle (not supplied) to
the ceiling above where powerhead’s mounting
holes will be once fully installed. A representative
mounting is shown
(Fig. 19)
Connect the powerhead to the ceiling mounted
perforated angle with M8x20mm screws and nuts.
Strips should not extend more than 18mm below
centre of powerhead mounting holes.
