CL290 Installation Guide

Tools Required

• Power Drill  
• 25mm, 15mm & 8m drill bits
• Philips screwdriver
• Hammer / mallet   
• Chisel 25mm
• Stanley knife
• Adhesive tape, pencil, bradawl, tape measure

• The hold open model is equipped with a snib on the backplate. This enables the latchbolt to be held open when required.
• Before commencing installation check that all parts are working correctly – press the code according to the code card and then the knob should turn and return easily under spring pressure. If you have a key override lock try the keys to ensure that they turn in the knob handle.
• If you intend to change the code, you should do it, if it is convenient, before installing the lock – see the code change instructions.
• Make sure that the lever handle of the backplate moves freely. If your lock is a hold open model then check that the snib will engage and hold the handle in the latch open position.
• Check that the latch bolt moves freely by pressing at the end and also by turning the flat spindle in the latch cam.

1.    Check the hand of your door

2.    Apply the template

• Crease the template along the door edge line and tape it to the door.
• Mark the 13mm holes, and the 3 x 8mm holes. Mark the centre line of latch in the middle of the door edge. Now apply the template to the other side of the door, aligning it with your first mark in the middle of the door edge. Mark the 4 holes again.
• Keeping the drill level and square to the door, drill the holes from both sides to avoid splintering out the door face.

• Mark a central point on the centre line of latch on the door edge.
• Mark the depth of 85mm on the drill bit with tape to act as a visible depth limit. Drill a 25mm hole, 85mm deep, keeping the drill level and square to the door.
• Insert the latch into the hole, and with the edges parallel to the door, draw around the face plate.
• Remove the latch. Score the pencil line with a Stanley knife to avoid splintering prior to chiselling. Chisel a 3mm rebate to fit the latch face flush to the door edge.
• Fix the latch with the wood screws, with the bevel towards the door frame.
  

3.   Latch support post

• Fit the latch support post in the back of the lockcase in hole A for a right hand door, or B for a left hand door.

6.    Fixing the lock

• Cut the fixing bolt to suit the door thickness, allowing at least one threaded section to screw into the lockcase.
• Hold the lock case and the backplate, with the seals, onto the door with the spindle in position.
• Using the fixing bolts screw everything together through the top and bottom holes of the backplate. Before final tightening make sure that the lock is vertical, and test the mechanism to ensure that it is all moving easily. Do not close the door until you are sure that the code works.
• Do not over-tighten the fixing bolts as this may cause distortion and lead to poor operation.

7.    Fixing the strike plate

• Ensure that there are no obstructions to prevent the door closing properly into its frame, such as litter trapped in the hinge side.
• Position the strike plate on the door frame so that it lines up with the flat of the latchbolt, not the plunger.
• Draw around the aperture of the strike plate. Chisel out the aperture 15mm deep to receive the latchbolt. Fix the strike plate to the surface of the frame with one screw only. Close the door and ensure that the latch bolt enters the aperture easily, and is held without too much play. When satisfied, draw around the final position of the strike plate, remove it and cut a 1mm rebate to enable it to fit flush. Re-fix the strike plate with both screws.

N.B. The plunger beside the latchbolt deadlocks the latchbolt and protects it against manipulation. It must not enter the strike plate aperture when the door is closed.
