Check operation of the coded front plateTurn the front plate over and note that the red tipped tumblers inside correspond to the code. The code may be entered in any sequence, i.e. 1370 may be entered as 3710 or any other sequence of those numbers. There are a total of 2,047 codes available, any of which may be entered in any order.If you intend to change the code you should do it, if convenient, before installing the lock – see the Code Change instructions. The CL500 model is intended to replace the conventional door furniture fitted to an existing mortice latch, or an existing mortice lock which has both a spring latch and a deadbolt. The square follower should be 8mm square. Any lock and key mechanism is retained to operate the deadbolt. The latchbolt will only operate by code, and not by key. A mortice lock case should have holes for fixing bolts to pass through on either side of the square latch follower and sometimes, additionally, a hole below the follower. See figure 1 and confirm that your lockcase is compatible with the CL500 lock plates. |  |
1. Hold the black neoprene seal with the three holes against the door, perfectly vertically, with the rectangular hole centrally over the follower. Mark the top and bottom holes on the door face, and repeat the procedure on the other side of the door. Remove the lock. At both points drill a 12mm hole through the door. Drill from both sides for greater accuracy and to avoid splintering out of the door face. Check that the existing spindle hole is at least 18mm diameter. Replace the lock. |   |
3. 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 full tighten the grub screw.
4. Cut two of the black socket head screws 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.
5. Apply the front and back plates, with the neoprene seals in position, against the door, over the protruding ends of the spindle.
6. 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.
7. 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.
1. Hold the black neoprene seal with the three holes against the door, perfectly vertically, with the rectangular hole centrally over the follower. Mark the top hole and the holes on either side of the follower, if not already drilled, then repeat the procedure on the other side of the door. Mark an extra hole on the inside of the door in line with the bottom fixing hole. Remove the lock. Drill the 3 x 12mm holes from both sides for greater accuracy, and to avoid splintering out of the door face. Check that the existing spindle hole is at least 18mm. Drill the extra 12mm hole 5mm deep on the inside of the door to accept the fixing nut on the adaptor plate. Replace the lock. |   |
