4. Carefully close door and check that catch Strike Block
just clears inside edge of Lever Catch – if necessary
adjust horizontal position of the (aluminium) catch
block.
Note:
It is permissible to file a small chamfer on the
outer strike end edge of the stainless steel Strike Block
to just achieve a running clearance, if necessary.
5. Check that door is secured in closed position and that a
very small clearance (less than 0.2mm) exists between
door and stop block. If necessary, adjust the thickness
of catch shim (by adding or removing 0.05/0.1mm
laminates) to obtain the correct clearance.
6. Replace and secure door cover.
Adjustment for Two Door Units:
1. Open door and note vertical position of catch Strike
Block. Remove Strike Block and add a 1mm catch
shim, or alternatively undo 8-32 UNC grubscrew until
block is free to rotate, unscrew block one turn and
secure in position with 8-32 UNC grubscrew, remove
0.4mm of laminates from existing catch shim.
2. Replace catch Strike Block and secure in vertical
position noted earlier.
3. Close door, push start switch, pull and release door
catch handle. Open opposite door and check that the
door with the new catch has not been released. If
further adjustment is required, add shim in increments
of 0.1mm.
4. Open door and remove existing stop block using a
25mm wide wood chisel. Scrape off any traces of
adhesive from frame.
5. Undo the M4 x 10mm long countersunk screws
securing the main liner in 8 positions and remove the
liner.
6. Undo the M4 x 10mm long countersunk screws
securing the switch assembly in 2 positions (to prevent
accidental damage to switch during adjustment
procedure).
7. Carefully close the door and measure gap between door
and frame (dimension A). Measure the thickness of
door stop and add 0.25mm (dimension B). Adjust the
thickness of catch shim (by adding or removing
0.05/0.1mm laminates) to equal the difference between
dimensions A and B. If the required catch shim
thickness cannot be obtained, then the position of the
