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.
