Installation situations/examples
Where should the fixing bracket for the lintel/ceiling and the opener head be fitted?
(as exemplified by a swing door)
To ensure optimum power transmission, the opener should always be fitted as close as possible
above the highest running point of the door.
• Determine the highest running point a (a = minimum distance between door leaf and garage
ceiling). There are several installation options depending on the determined dimension.
1. Dimension a from 38 mm to 140 mm
– Fit the garage door opener to the ceiling.
– Attach the fixing bracket for the lintel/ceiling to the lintel or ceiling (preferably to the lintel).
– If attaching to the lintel, maintain a gap of 15 mm.
2. Dimension
a
greater than 140 mm
– Attach the fixing bracket for the lintel/ceiling to the lintel maintaining a gap of 50 mm between
the under edge of the rail and highest running point of the door.
– Suspend the garage door opener from the ceiling (perforated rail required, see “Accessories”).
3. Dimension a less than 36 mm
– Attach the fixing bracket for the lintel/ceiling and garage door opener to the ceiling behind
the open garage door (extension rod required, see “Accessories”). Note overall length.

• To facilitate unwinding of the chain J the cover of the small accessories packaging can be detached
and used as a base.
• Wipe excess oil off the chain with a cloth.
• Unwind the chain into the running rail.
– Always feed the chain through the carriage D on the driver side I . To do this, disengage the
carriage (metal lever must engage with the plastic lever).
• Connect both sides of the driver I to chain J with chain joint H .
• To insert the chain into the chain deflector F spring E must be compressed with force.
Use guide arm M to facilitate compressing the spring.
– The chain must be placed correctly in its guide and must not be twisted.
• Attach the emergency release cord O .
• Attach the pinion cover N .
