Model 420/425 Installation Instructions
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.
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:
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.
--------------------
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
ding to the hand of your door (see diagram).
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.
