HANG THE OPENER
The opener must be securely fastened to a sound
structural support above the opener.
1.Postion the opener as in the previous step. Check the rail
is centred over the door (fig. A).
2.The mounting bracket must be mounted so far back that
the carriage is not obstructed. The carriage can not pass
through the bracket. Mounting at the very back (fig. B) is
ideal.
3.Bend ceiling fixtures (1) in such a way that they lie flat
against the ceiling. Depending on how large the distance
to the ceiling is, none, one or two of the support brackets
are to be mounted (fig C1, C2 and C3).
4.Secure the hanging brackets to the ceiling using
appropriate screws.
5.Place mounting bracket (2) around the rail, then align to
the ceiling fixture and bolt them together.
6.Centre Rail Support Brackets (kit contents item 12) can
be installed along the centre of the rail if required. This
will reduce flex in the rail that may occur with segmented
rails or rail extensions.
7.Check the opener is securely centred over the door.
Remove the 50 mm spacer, and any other assembly
tools. Operate the door manually and check for
unrestricted operation.
