Door Catch and Lock Replacement and
Adjustment
Correct operation and adjustment of the door catch, sensing and locking
mechanisms is vital for trouble-free operation.
Replacement Door Lever Catch set (part #200895JF) includes
the Catch Plate and Strike Block. The (chrome) Strike Block
supplied in a new set should
not
be used – it should be replaced
with the original (or replacement) stainless steel Strike block
(to Drg. B39278).
1. To replace the Door Lever Catch, undo M4 x 10mm
long countersunk screws securing the outer door cover
in 6 positions, and remove cover.
2. Open door and undo M5 x 35mm long countersunk
screws securing lever catch to door bracket in 3
positions (for version with 50mm lead and a counter
fitted to door, the M5 screws are secured with M5
crinkle washers and M5 nuts).
3. Replace and secure Lever Catch and before fully
closing door, check that top of Catch Plate is positioned
approximately 3mm above top of Lever Catch (when
viewed from the front) – adjust vertical position of
Catch Plate on the Main Frame if required.
(Further vertical adjustment of the Door Lever Catch is
available by way of the slotted holes in the Lever Catch
mounting plate
, located inside the hollow door frame
section. Slacken the three M4 Nuts securing the
mounting plate to the inside of the door section and
adjust the Lever Latch as required.)
Note:
If it is necessary to replace the stainless steel
Strike Block, undo 8-32 UNC grubscrew and unscrew
strike block from (chrome) Catch Plate. Replace
stainless steel Strike Block and adjust its position until
