9 Remove the 4 socket head bolts from the back plate (2 are found
under the battery cover). This will release the inside fixing plate.
10 Cut the fixing bolts to correct length. Measured from beneath the
bolt head, the length should be the door thickness, plus
approximately 15mm (
1
/2”) to the nearest cutting point of the bolt.
N.B. Always cut the bolts at one of the cutting points so as not to
damage a thread. Use the cutting edges of pliers to crimp
strongly several times around the selected cutting point. The
surplus end should break off quite easily.
11 Put the spindle into the latch with the spring on the front plate
side of the door.
12 Apply the front plate over the spindle, passing the cable tube
through the door and the latch support post through the latch.
Place the fixing plate over the cable tube and spindle. If installing
the Audit Trail Option take the USB Connector (19) and place
over the cable tube, securing in place with double sided tape.
Screw the ring nut onto the cable tube until finger tight. Fit the
alignment insert over the spindle. Screw the fixing bolts through
to the front plate. (See diagram D on page 7).
13 Check that the spindle turns freely, and the latch retracts and
projects smoothly, with the alignment insert in place. If it is tight,
loosen the fixing bolts slightly and adjust the position of the
fixing plate until the spindle will turn freely. Tighten the fixing
bolts. Test the spindle again. Do not over-tighten the bolts as this
may cause the door to distort and affect the lock function.
REMOVE THE ALIGNMENT INSERT.
5 Reinsert the latch and fix the screws, with the bevel towards the door
frame. (See diagram B)
6 Fit the latch support post on the inside of the front plate, in outer hole
Side A for a left hand hung door and in outer hole B for a right hand
hung door. (See diagram C below).

7 Screw the cable tube into the front plate, passing the cable through the
tube. For doors less than 45mm (1
3
/4”) thick screw the tube all the way
to the end of the thread. For doors more than 45mm (1
3
/4”) leave an
appropriate amount of thread showing. Example: For a 60mm (2
3
/8”)
thick door leave 15mm (
1
/2”) of thread showing.
8 Fit the self-adhesive gaskets to the front and back plates. The gaskets
provide friction against the door so that it is not necessary to overtighten the fixing bolts to provide stability.
