INSTALLATION STEP 5
Hang the Opener
Three representative installations are shown. Yours may
be different. Hanging brackets should be angled
(Figure 1) to provide rigid support. On finished ceilings
(Figure 2 and Figure 3), attach a sturdy metal bracket to
structural supports before installing the opener. This
bracket and fastening hardware are not provided.
1. Remove foam packaging. Measure the distance from
each side of the opener to the structural support.
2. Cut both pieces of the hanging bracket to required
lengths.
3. Drill 4.5 mm pilot holes in the structural supports.
4. Attach one end of each bracket to a support with
8 mm coach bolts.
5. Fasten the opener to the hanging brackets with
8 mm hex bolts, spring washers and nuts.
6. Check to make sure the rail is centred over the door
(or in line with the header bracket if the bracket is not
centred above the door).
7. Remove timber spacer. Operate the door manually. If
the door hits the rail, raise the header bracket.
8. Grease the inside of the rail surface where the trolley
slides with rail grease (provided).
NOTE: DO NOT connect power to opener at this
time.
To avoid possible SERIOUS INJURY from a falling garage door
opener, fasten it SECURELY to structural supports of the garage.
Concrete anchors MUST be used if installing ANY brackets into
masonry.
