5 Adjust to door
thickness
1 Determine the door’s thickness.
2 Pull the rose locking pin and rotate the
outside rose liner until the proper groove
on the through bolt stud lines up with the
hub face.
Note 1: Make sure that the locking pin fully
locks into the rose liner.
Note 2: Locksets will fit doors 1 3/4“ to
2 1/4“ thick. (A spacer is available for 1 3/8“
doors.) See the enlarged view for the correct
rose adjustment for these thicknesses.
6 Engage retractor in
latch
■ While feeding the motor wires through the
3/8“ hole to the inside of the door, insert
the lock chassis into the hole.
Caution: Be sure that the latch tube
prongs engage the chassis frame and
that the latch tailpiece engages the
retractor.
7 Install through-bolts
and rose liner
1 Making sure that the motor wires come
through the notch in the 2 1/8“ hole, align
the holes in the liner with the holes pre-
pared in the door.
Caution: Make sure that there is clear-
ance for the motor wire between the
rose liner and the door.
2 Install the through-bolts through the liner
and door in the top and bottom holes.
3 Tighten the liner onto the door with the
through-bolts.
8 Make wire connections
1 Insert the bushings into the wire hole, as
shown in Figure 9 and Figure 10.
2 Feed the outside wire harness connector
through the top wire hole (Figure 9).
3 Temporarily rest the trim on the door by
inserting the trim studs into the stud holes.
4 From the inside of the door, connect the
motor connector to the mating connector
from the circuit board (Figure 10).
Note: It is possible to plug the battery pack
into the motor connector and the motor wire
into the battery connector. To avoid this,
connect only the connectors with matching
wire colors.
