Step 11
Fix the two plates together using the socket head bolts, starting with the top fixing. Ensure that the two
plates are truly vertical and then tighten the bolts using the ‘T’ shaped Allen key. Do not use excessive force.
Step 12
Check that the lever handles are correctly fitted for the hand of door. To change the hand of a lever handle,
loosen the grub screw with the small Allen key, reverse the lever handle and fully tighten the grub screw.
Step 13
Before closing the door, enter the code and ensure that the latchbolt will retract when the lever handle is
depressed. Now check the operation of the inside lever handle. If there is any binding of the handles or latch
then loosen the bolts and reposition the plates slightly until the correct position is found, and then re-
tighten the bolts.
Model CL620/625 Installation Instructions
The model CL620/625 has a mortice lock and may be used as a new installation on a door, or where an
existing lock is to be replaced.
Important: The mortice lock provided (fig.2 - page 11) has features which are not found in most other locks
and so it is recommended that you familiarise yourself with them as follows:
A. When necessary the hand of the latchbolt can be changed by removing the three screws holding the
faceplate to the lockcase, reverse the latchbolt, and tighten the screws back up, ensuring that the latchbolt is
central.
B. Put the key in the cylinder and insert it centrally into the lockcase. Fix it in position with the long bolt
through the faceplate. It should now be possible to project and retract the deadbolt with the key, and also to
retract the latchbolt.
C.The square latchbolt follower is in 2 parts: the inside ‘panic function’ follower will retract the latchbolt and
also the deadbolt when it is projected. The effect of this is to ensure that it is not possible to accidentally
lock someone in a room because the deadbolt is projected. The outside follower will always retract the
latchbolt whenever the lever handle is depressed after a correct code is entered, but it will not retract the
deadbolt. The hand of the ‘panic function’ is determined as follows: the grub screws on the split follower
facing the code side must be removed. This prevents the outside handle retracting the deadbolt.
Never remove grub screws from both sides at the same time. All door locks should be installed with a
degree of precision to ensure that all components are horizontally and vertically accurate in relation to each
other, and in relation to the door. Do not install the lock where it will involve cutting into a joint between the
door stile and a mid-rail.
Step 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 (12”) below it.
Step 2
Hold the 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 holes, and the holes to be drilled
for the mortice.
Step 3
Apply tape to the 16mm ( ⁄ ”) drill bit at 90mm (3 ⁄ ”) from the tip to act as a depth guide when drilling the
mortice holes. Ensure the drill is level and parallel to the door face and drill the holes as indicated on the
template. Remove the remaining wood with a chisel to leave a clean mortice hole which accepts the lockcase
without forcing. With the lock in the mortice make sure that the forend is parallel with the door edge and
mark the outline of the forend plate. Cut the outline with a Stanley knife to avoid splitting out when
chiselling. Chisel a rebate sufficient to accept the forend flush with the surface.
Step 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 the procedure on the other face of the door.
Step 5
Drill the holes from both sides of the door to improve accuracy and to avoid splintering out the door face.
Step 6
Install the lockcase in the door.
Step 7
Cut three of the socket head bolts to the required length for your door. Approximate overall length should
be door thickness plus 25mm (1”) to allow about 10mm ( ⁄ ”) of threaded bolt to enter the outside plate.
Step 8
Take the BLUE or RED tipped spindle and fit to the code side according to the hand of your door (see
diagram).
