OFF CENTRE INSTALLATION OF OPENER
In situations where obstruction prevent mounting the
opener centrally, offsetting the opener attachment is
possible within the following range -
1/4 Door width
from centre.
NOTE: Even though it is acceptable practise to off
centre mount the opener, the further off centre the
opener is mounted the more dependent is the door
operation on a good installation. This relates to
correct set-up of opener and track, and correct door
balance.
The installation of the IR Safety Sensor is
recommended for an off centre mount application.
ONE-PIECE DOOR INSTALLATIONS
• Generally, a one-piece door does not require
reinforcement. If your door is lightweight, you can
refer to the information relating to sectional doors
in Installation Step 11.
•
Depending on your door’s construction, you may
need additional mounting hardware for the door
bracket (Step 11).
• The gap between the bottom of the garage door
and the floor cannot exceed 6mm. Otherwise, the
safety reverse system may not work properly. See
Adjustment Step 3. The floor or the door should be
repaired.
