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.
