PLEASE LEAVE THESE INSTRUCTIONS WITH THE END USER
On either face of the door, mark any required hole centres for follower
and accessory bolt through fixings, and drill accordingly. Remove any
swarf from the mortice.
Note:
Never drill any holes while the latch is in the door.
Insert the latch, including loose faceplate into the mortice. Ensure the
bevelled face of the latch is facing the frame direction. Fix in place
with included screws.
Check operation prior to preparing the frame for the strike plate.
With the latch fitted and the door in the open position, close the door
gently against the frame and mark the top and bottom edge of the
latch/deadbolt on the door frame.
Transfer these two marks across to the inside of the door frame
rebate. Mark an additional horizontal line approximately 2mm above
the top line.
This line represents the top inside edge of the aperture within the
strike plate and will provide operating clearance.
Identify where the resting position of the latch will be, and draw
around the strike plate accordingly.
Chisel out accordingly for the strike plate with sufficient mortice for
the dust box ensuring, when fitted, the strike plate is flush with the
frame.
Close door to check proper operation. Adjust anti-rattle tabs as
necessary.
A care and Maintenance Schedule should be carred out regularly.
Check that the lock and the strike plate are correctly aligned and that the fixing screws are tight.
After 20,000 operations, apply fine machine oil, or GT85 (or similar) PTFE lubricant to the latchbolt and
deadbolt slots, operate a few times to work the lubricant into the components, wiping away any excess.
Ensure that any door or frame finishes are protected. Repeat after each additional 20,000 operations.
