Mounting installation plate
Ensure that the wall is strong enough to withstand the weight
of the unit. Otherwise, it is necessary to reinforce the wall
with plates, beams or pillars.
Use the level gauge for horizontal mounting, and fix it with
4 suitable screws.
In case the rear piping draws out, drill a hole 65mm in
diameter with a cone drill, slightly lower on the outside wall
(see figure).
