Step 3: PIN 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.
e. Make sure that the screws do not project into the area where the ring gear
will fit.
Step 4: FIT THE OPENER
1. Choose whether the opener is to be fitted right hand or left hand (refer to Position and Sideroom) - right hand
fitting is recommended where possible.
2. At the end opposite to where the opener will be fitted, check to make sure the “U” bolt is tightened securely.
3. 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.
4. 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.
5. 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.
6. 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 poor sideroom installations
the door may have to be taken down.
7. Fit the opener as follows:
• Disengage the opener by pulling the disengagement handle
down (there will be an audible click), so that the ring gear
can be rotated by hand.
• Slide the opener over the door axle and into the drum of the
door. Ensure the ring gear is pushed in as far as possible
(without interfering with the door curtain) so that the drive
finger completely engages one of the door drum wheel spokes.
