Next, drill the holes for anchoring the fastening brackets to
the wall using as a first option the 4 holes on the ends of
the bracket as shown on the drilling template (see fig. 6).
If the wall is not very solid, it is advisable to use some
extra anchor bolts.
Fig. 6
As you can see, the bracket can be fastened in a number
of different ways and positions. The air conditioner is
heavier on the left-hand side, so it is best to make sure of
a solid anchorage on that side. The anchor bolts provided
require holes with a diameter of 10 mm. In any case, the
wall should be inspected carefully to determine the best
possible anchorage and type of bolts suitable for particular
situations.
Warning: The manufacturer is not liable in case of
underestimation of the structural consistency of the
anchorage made at the time of installation. We
therefore recommend that you perform this operation
with the maximum care as, if not done properly, it
can cause serious damage to persons and property.
When installing models equipped with heating pump, if
no drainage well for condensate has been provided built
into the wall (see paragraph 2.3.2), it will be necessary,
to allow for drainage of the condensate, to drill a hole
through the wall measuring 16 mm in diameter in the
position shown on the template (see fig.6).
