Keyboard Overlay Removal & Refitting
If the overlay requires replacing then the overlay and display board can be
removed as follows:
NOTE
The watertight seal between the keypad and the control box face is very strong.
Care must be taken whilst attempting to break the seal. Excess force may
damage the control box causing a potentially poor seal between the new keypad
and control box.
1. Remove the display board from the overlay as described in
removal and refitting"
unplug or unclip the connector and ribbon cable for this purpose. Place the
removed display board carefully in the bottom of the door.
2. Undo the 10 hex M3 pillars that secure the overlay to the control box door.
3. From the outside of the control box, using a thin bladed palette knife gently
insert into the seal around the overlay and the control box, carefully break the
seal by working the knife sideways around the full circumference of the seal.
4. Remove the overlay.
5. Clean off any old seal material remaining on the control box door prior to
replacing the new overlay.
6. Re-apply a new seal to the front of the overlay as shown in
this section.
7. Fit the overlay into the control box and replace and tighten the 10 pillars.
Ensure squeezed silicon can be observed around the full circumference of the
overlay. Excess silicon can be removed by folding a piece of thin stiff
cardboard into a V and gently running it around the seal removing the silicon.
