Installation & Operating Instructions
V2.09/19
STEP 5.
Install the lintel/ceiling bracket (5). You can attach the lintel bracket either to the lintel above the door (head)
or the ceiling. With the door closed, mark the centerline of the door extended onto lintel wall above door
with a vertical line. Open door to highest point and draw an intersecting horizontal line on lintel wall at least
50mm above high point to allow for clearance for top edge of the door. Fix lintel bracket into position using
the screws provided.
STEP 6.
Attach the rail to the lintel bracket aligning the bracket holes and securing with the long clevis pin (5) and R-
clip (5). Use foam packaging as a protective base under the powerhead to prevent damage. You may require
help with this step if the door spring is in the way.
STEP 7.
Disengage the trolley mechanism and slide back towards the powerhead securing the straight arm up into
the rail assembly, using tape or rope, to avoid a hazard. Raise opener onto support, opening the door
completely. Use a 50mm spacer between the door and the rail. The positioning of the rail should be
centered over the door, parallel to the horizontal door panels.
STEP 8.
Hang the opener. If mounting directly to ceiling, screw fixing bracket (8) directly into structural support, see
Fig. 1. If hanging the opener below the ceiling, bend the hanging brackets (9) provided and secure to both
the ceiling and the fixing bracket, see Fig 2. Remove spacer and assembly tools and manually operate door
to check for unrestricted operation. If necessary, adjust the manual release cord to no higher than 1.8m
from the floor.
