INSTALLATION (continued)

STEP ELEVEN:

Determine a suitable method to support the drive unit from the ceiling depending of the direction of ceiling batons

or joists. Supplied in the box is the Hanger Bracket, (Fig. 9a).

The sides of the hanger can be cut along the pre-punched small holes and then folded to the required angle as

shown in Fig. 9b. The hanger can be secured on the end of chassis (as shown in Fig. 9a), or on top of the center of

the C rail using two 10x16 wafer Tek/YZC screws (not supplied) shown in Fig 9b

Perf angle can also be straight screwed onto the chassis for mounting the unit as shown in Fig 9c and Fig 9d.

STEP TWELVE:

Mark the top center of the door. Raise the door to the fully open position and transfer the mark directly up to the

ceiling. This will ensure when ﬁ xing the motor that the unit will pull centrally on the door throughout its range of

motion.

Failure to do so may result in damage to the motor or other mechanical components and ﬁ xtures.
