Caution
Make sure that the diameter of the dowel holes is accurate to avoid
falling out of the dowels! Use the mounting glue to secure the dowels if
necessary.
Make sure that the depth of the dowel holes is accurate!
Do not use low-quality dowels to avoid their pulling out of the wall!
Having removed the front panel, make sure that no dirt gets inside the
product (especially onto the sealing surface).
Never turn to align the box assembly after mounting. Make 2N IP Verso
®
sure that the flush mounting boxes have been installed accurately.
Check the plasterboard wall and room interior pressure values. If the
difference between the values is too great (as a result, e.g., of
overpressure ventilation), separate the intercom using, for example, the
mounting box enclosed and seal the cable passage to avoid speaker
damage.
Surface mounting may cause problems on places exposed to potential
vandalism (such as public garages, etc.). In this case, use steel anchoring
elements instead of the dowels and screws included in the delivery.
Make sure that the installation surface is perfectly flat with the maximum
inequality of 0.5 mm. (e.g. boards, glass, cut stone, etc). If this is not the
case, use a flush mounting backplate – , or level Part No 9155061 9155067
the wall surface.
Always use an installation backplate for uneven installation surfaces.
While flush mounting, make sure that the box is installed properly, i.e.
with the box frame on the wall surface. There are snap-off protrusions
on both sides of the flush mounting box to facilitate positioning. Make
sure that the frame is placed precisely onto the flush mounting box off
the wall to provide effective sealing and avoid water penetration into the
intercom. Refer to the pictorial instructions inside the flush mounting
box package.
Any intentional mechanical damage (drilling, main unit tampering, etc.)
results in a loss of warranty.
