The door must be well balanced and be in a

reasonable operating condition. The ideal

sure that all door locks, ropes, chains etc. are

neither released, nor disabled and remove

unnecessary accessories.

majority of installations!

Move the door manually to the mid open

position. Place the weight bar on the bottom

rail, in the middle of the door and secure with

the fasteners provided (FIG. 2). Check the

operation of the door again. If the door feels

heavy it may require extra tension to be added

to the door springs. Refer to the door

Installation manual from the manufacturer on

how to tension the door.
