INSTALLATION

ONE-PIECE DOOR

WITH NO TRACK

PROCEDURE: Measure the distance from floor to top of door (in fully open position and parallel to the floor).

Using a stepladder as a support, raise opener chassis to

the same distance from the floor (chassis will have a slight angle as shown).

The top of the door should be level with the top of opener. For maximum efficiency, do net position opener chassis more than 2 inches above this point.
