Codelocks CL425 Mortice Lock with Double Cylinder User Manual
Page 4
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 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 screws, and the holes to be
drilled for the mortice.
STEP 3
Apply tape to the 16mm drill bit at 90mm
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 two of the black socket head bolts to
the required length for your door.
Approximate overall length should be door
thickness plus 25mm 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).
Fit the butterfly spindle to the inside,
non-code side.
Model 420/425 is a complete locking unit with all the parts necessary
for a new installation, or the total replacement of an existing lock.
MODEL 420/425 INSTALLATION INSTRUCTIONS
A. When necessary the hand of the
latchbolt can be changed by removing
the three screws holding the faceplate
to the lockcase, loosen the screw
holding the latchbolt in place, reverse the
latchbolt, and tighten the screw 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.
IMPORTANT The mortice lock provided (fig. 1) has features which are not found in most
other locks and so it is recommended that you familiarise yourself with them as follows:
STEP 9
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 10
Apply the front and back plates, with the
neoprene seals in position, against the
door, over the protruding ends of the
spindle.
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. Do not
use excessive force.
STEP 12
Before closing the door, enter the code
and check 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 the latch then loosen the bolts
and reposition the plates slightly until the
correct position is found, and then re-
tighten the bolts.
STEP 13
Fit the double Euro-profile cylinder and
secure it with the long screw through the
faceplate. Fit the cylinder escutcheons.
STEP 14
Check that the deadbolt will project and
retract by key, and that the key will also
retract the latchbolt.
Check that the inside lever handle WILL
retract the deadbolt simultaneously with
the latchbolt.
Check that the outside lever handle WILL
NOT retract the deadbolt.
STEP 15
Mark a vertical line on the door jamb half
the door thickness away from the door
stop. This gives the centre line of the
strike plate. Align the Strike Plate Template
with the height line, with the arrow heads
aligned with the centre line. Mark the fixing
holes, and draw around the apertures for
the latchbolt and the deadbolt. Chisel out
the latch aperture to 12mm deep, and the
deadbolt aperture to 22mm deep.
Fix the strike plate with the top screw only
and gently close the door. Ensure that
the latchbolt enters its aperture easily and
holds the door without too much ‘play’.
When satisfied, draw around the final
position of the strike plate, remove it, and
cut a rebate to allow it to fit flush to the
surface. Re-fix the strike with both screws.
