NOTE: It is recommended that the switch be installed on the latch side of the door. However, hinge-side installation is acceptable.
Some experimentation with the switch position may be necessary to achieve proper step operation. The stop should begin to extend when the door is opened between one and four inches. Position the switch in the door jamb. Locate the magnet opposite the switch.
Check for ample clearance in the door frame for the body of the door switch. Under no circumstances should the door switch be forced into its mounting position. Wiring to the switch should come up through the hollow door frame. After wiring is complete, mount the switch to the door jamb.
Install the magnet in the door, opposite the switch. Vertical placement of the magnet is critical to proper door switch operation. (See diagram above)
