PIN DOOR CURTAIN TO DOOR DRUM WHEEL
3.1
Pinning the door curtain to the drum wheel will reduce possible forced lifting of the door.
Close the door to the fully closed position and mark the two positions where the curtain is to be pinned onto the
drum wheel on either side of the door. The marked positions (pinning locations) should be at least 90
o
apart (see
Fig. 8).
2.1
Raise door a little so that you can access the marked positions and pin curtain to drum wheel with self-drilling
tech screws or rivets.
WEIGHT BARS (Optional – not supplied)
4.1
Weight bars may be required. Their main purpose is to eliminate the possibility of the door curtain ballooning on
initial start-up (from the door fully open position). After installing your new opener, if your door balloons on initial
start-up then we recommend that you fit one or two weight bars to the bottom edge of your door (total weight 5-
7kg) as detailed below. (See Fig. 9).
4.2
Move the door manually to the mid-open position. If fitting one bar, centre it between either sides of the door. In
the case of two weight bars, fit them +/- 300 mm in from either side of the door. This ensures an even distribution
of the weight. Once the weight has been fitted the door should have a natural tendency to lightly freefall from
the mid-open position when in manual mode. The door should not drop rapidly!
