KDC3905
Before installing the cassette, it is necessary to protect the rear opening against flooding. If there
is a possibility of dripping water on the wall to which the device will be fixed, it is absolutely
necessary to secure the opening by using a seal which, after pressing the cassette to the ground,
will prevent water from leaking through installation hole to the inside of cassette. It is possible to
use e.g. rubber gaskets that are used to seal windows. The cables should be led
“
from the bottom
”
to prevent the water from dripping through the cables to the inside of keyboard.
The cassette should be fixed to the wall with 4 screws with plastic pegs, through holes in the back
wall of cassette and visible from the front of cassette on the left and right side. Install the side
masking strips by inserting them at an angle and pressing them towards the wall. Insert the plastic
caps from the top and bottom of cassette.
