Codelocks CL525 Mortice Lock with Double Cylinder - Manual (Page 5)

Model 520/525 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. 2) has features which are not found in most other
locks and so it is recommended that you familiarise yourself with them as follows:
MODEL 520/525 INSTALLATION INSTRUCTIONS
STEP 7
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 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.
STEP 9
Fit latch support post into
back of the
code side front
plate according to the hand
of your door, A for a right
hand door, or B for a left
hand door (see diagram).
STEP 10
Cut two of the back 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 11
Apply the front and back
plates, with the neoprene
seals in position, against the
door, over the protruding
ends of the spindle.
STEP 12
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 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 slightly and
reposition the plates slightly
until the correct position is
found, and then re-tighten
the bolts.
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.
