1. Lightly mark a height line on the edge and both faces of the door, and the door jamb, to indicate the top of the
lock when fitted. Mark a line down the centre of the door edge, extending above the height line and 300mm
(113/4”) below it.
2. Hold the mortice lock template against the edge of the door with the top in line with the height line, and with
the arrows in line with the ‘Centre of Door Edge’ line. Mark the positions of the fixing screws, and the holes to be
drilled for the mortice.
3. Drill the marked holes 90mm (31/2”) deep and form the mortice for the lock.
4. Fold the template accurately along the dotted line and tape it to the door face with the top in line with the
height line, and the fold on the door edge. Mark the centres of all the holes to be drilled. Remove the template and
repeat on the other face of the door.
5. Drill the holes from both faces of the door to improve accuracy. Do not drill right through the door as this will
damage the door when the drill breaks through.
6. Check that the two screws have been removed from the follower on the outside of the door. DO NOT remove
the screws from both sides of the follower.
7. Install the lock case in the door and fit the cylinder. Confirm that the key will double-throw the deadbolt,
retract the deadbolt, and retract the latchbolt.
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 over-tighten the bolts to provide stability.
9. Remove the five socket head bolts from the back plate (two are found under the battery cover). This releases
the inside fixing plate.
10. Cut the fixing bolts to the correct length. Measured from beneath the bolt head the length should be ‘door
thickness’ plus approximately 15mm (5/8”) to the nearest cutting point of the bolt.
N.B. Always cut the bolts at one of the reduced sections so as not to damage a thread. Use the cutting edge of
pliers to crimp strongly several times around the selected cutting point. The surplus end should break off quite
easily.
11. According to the door thickness, insert one of the short spindles into the outside follower of the lock-case with
the spring facing out. Use the 22mm (7/8”) spindle for doors between 35-50mm (13/8” -2”), and the 28mm
(11/8”) spindle for doors between 45-65mm (13/4” -21/2”). Insert the longest spindle into the inside follower with
the spring facing out.
12. Position the front plate over the spindle passing the cable through the door. Then fit the long spindle into the
lock case with spring in place. Fit the inside fixing plate over the spindle, compressing the spring to hold the
spindle in place, using the three pre-cut fixing bolts.
13. Connect the cables.
14. Fit the back plate cover of the CL5520. Fit the batteries and the battery cover. Fit the cylinder cover and the
handles. The inside handle should retract the latchbolt, and the latchbolt should automatically project again when
the handle is released. With the key turned 90° clockwise the outside handle should retract the latchbolt.
