Proceed as explained below:
1 . Position the plate on the wall at a suitable height and keep it as horizontal
as possible while fixing it (use a level) .
2 . Mark the position of the fixing holes .
3 . Make the fixing holes using a drill and Ø 8mm drill bit, and insert the
expansion plugs .
4 . Chose the exit side of the connection pipes . It is recommended to use the
back outlet on the right-hand side, however, if this is not possible refer to
paragraph "OTHER INSTALLATIONS" .
5 . Make a Ø 55mm or Ø 70mm hole on the wall (Fig . 1), slightly descending
outwards, starting to drill on one side of the wall (A) and finishing on the
opposite side (B) to avoid unwanted breakages of the wall .
6 . Fix the plate inserting the relevant screws into the four holes previously
drilled .
7 . Lift and turn with care the sections of the pipe necessary for the connection
with the outdoor unit and route them through the hole .
8 . Route the condensation drain hose through the same hole . According to
personal needs, this hose can be routed in other directions, provided that a
minimum inclination is always observed to allow the regular condensation
drainage .
9 . Securely hang the indoor unit to the fastening plate hooks .
10 . Check unit fastening conditions by moving it to the left and to the right .
Note: In order to make the fastening to the plate easier, keep the unit lower
part lifted and then lower it in a perpendicular position while easing the sheath
in place (Fig . 2) .
The experience of the installation technician will guarantee the perfect
execution of all operations, according to any specific needs .
