Step1
Check the door is in good working condition, manually open and close the door to make
sure the door operates smoothly and freely.
The door must be well balanced.
Check to see if there is a solid frame in the wall above the center of the door.
Close the door.
Measure the door width, mark the centerline of the door using a pencil, and extend the
line down to the door surface, then up the wall above the door.
Check the installation height of the operator. Slowly open garage door and observe the
highest point of door while moving. Close the door again and mark this highest point on
the wall, mark a horizontal line across the vertical centerline around 40mm above the
highest point. (Note: there should be 80mm space between this horizontal line to the
ceiling. If there is not enough space, please use the max height possible to allow the
header bracket to be fitted properly. )
