Mounting the Unit (continued)
Side room to imposing structures (see right)
Note: The Fire Shutter limit housing requires
adequate clearance to allow setting of limit cams
during installation. 150mm is the minimum
recommended clearance between wall and lid.
Where there is insufficient side room, consider using
the opposite hand opener and mount inboard with a
Grifco
™
Inboard Mounting Kit, Part No. IBMK.
Ensure the mounting position allows the hand chain to
hang free of obstructions (see right)
Ensure hand chain is not twisted when making the
join!
150mm Minimum
The drive sprocket must be aligned with the door
sprocket, and locked using 2 x M8 hi-tensile grub
screws tightened to min 20Nm. Grub screws must be
set between 90˚ and 120˚ apart, with one grub screw
lying over the drive key.
Chain tension should be set between 10-20kgs, ensuring
both sides of the linkage are taught. Where practicable, use
the weight of the opener as a preload, then tighten
mounting bolts. M12 fasteners should be tightened
between 80-90Nm.
INSTALLATION

The patented ACEM features allows the use of the hand chain in the event of a power failure. Simply pull on the
hand chain in either direction to operate the door manually.
Warning! Ensure power is isolated when using this feature.
The ACEM label (see right) must be fixed in close proximity to the controller e.g. on the door track.
