2.3 PINNING THE DOOR CURTAIN
Pin the door curtain to the door drum at each end of the door to maintain security
when the opener closes and locks. With the door fully closed:
a. Mark positions to drill in both drums as shown.
b. Open door slightly to get access to these positions.
c. Drill using 3.2mm (1/8") drill.
d. Fit a No 10 x 32mm screw and washer to each drum. While this screw
should be positioned as low as possible, make sure that it does not alter the
normal curtain to guide approach (lead-in angle).
e. Make sure that the screws do not project into the area where the ring gear
will fit.
2.4 FIT THE OPENER
a. At the end opposite to where the opener will be fitted, check to make sure the “U” bolt is tightened securely
and fit the anti-coning collar to the axle ensuring it is in contact with the door drum – right hand fitting is
recommended where possible.
b. Open the door completely and tie 2 safety ropes around the door roll approximately 300mm from each end (not
too tight) as a safety precaution.
c. At the end where the opener is to be fitted, support the door. It is
recommended that you support the door with either:
•
a sling or a block and tackle from above the door, or
•
a suitable stand e.g. a ladder and blocks (see illustration). If you use
blocks make sure they are flat on the top of the ladder and that they
are wide enough to take the weight of the door without damaging it.
Warning - make sure the support is snug under the door and that both the support and door
are stable and will not move.
d. Mark the position of the “U” bolt in the door bracket and the position of the door bracket on the wall to assist
when reassembling (use masking tape or marker pen).
e. Remove the “U” bolt (or bolts) and saddle from the door bracket at the end where the opener is to be fitted.
Remove this door bracket allowing the door to rest on the support (see illustration).
Note: For minimum sideroom installations the door may have to be taken down.
