2.5 - INSTALLATION OF THE INSIDE UNIT
2.5.1 - Installation of fastening plate
After having checked that described in paragraph "2.2"and on the previous page (figure X1), assemble the
fixing plate (7) taking the dimensions stated in figure into consideration.
a. Position the plate against the wall.
b. Mark the drilling points, making sure that they are level.
c. Make the holes necessary in the wall using a suitable bit.
Make sure there are no pipes or electric ducts in the drilling area.
d. Insert the plugs (4) into the holes and fix the plate (7) to the wall using the screws (3) supplied (figure 5).
Using a spirit level, make sure that the fixing plate (7) is level.
e. If the wall is in wood, use relevant countersunk-head screws (not supplied).
f. Check the stability of the plate (7), moving it laterally and vertically.
2.5.2 - Realisation of pipe passage holes
If the connection lines arrive from the rear right of the indoor unit, a hole must be made for passage of the
piping, as successively described.
a. Prepare the hole slightly below the mounting plate, it should have a diameter of approximately 65 mm
and a slope of 5% towards the outside to allow the condensate to drain correctly (figure 6).
b. Cut the wall through pipe so that the length exceeds the thickness of the wall.
2.5.3 - Piping connection (figure 7)
For the left (C) and right (F) piping, remove the respective pipe covering (B or G) from the lateral panel.
It is recommended to keep the pipe covering that has been removed, since it can be re-used if the
air conditioner is installed in another position.
For the rear right (E) and rear left (D) piping, install the pipes as illustrated in figure 7.
Bend the connection pipe, which must be laid at a max. distance of 43 mm from the outside wall.
Fix the end of the connection pipe (I). (see "Execution, installation and connection of the refrigeration lines").

D Left rear piping
a. Attach the upper bracket present in the rear part of the indoor unit to the upper hook of the fixing bracket
(pos. 7 - figure 8).
b. Move the unit laterally to ensure it is correctly attached to the fixing hook (7).
c. Piping connection is easily performed by lifting the indoor unit and introducing cladding between the same
and the wall.
Remove the cladding once connection has been completed.
d. Push the lower part of the indoor unit towards the wall to attach it to the fixing bracket (pos. 7 - figure 8).
e. Try and move the indoor unit laterally and vertically to make sure that it is attached securely.
2.5.4 - Drain pipe connection (figure 9)
a. Insert the drain pipe (A), making sure that it slopes downwards.
