MACHINE INSTALLATION
PACKING AND STORAGE
All the models are provided with their own specific cardboard boxes.
The units must be moved by hand.
The box containing the unit gives instructions about how to handle the machine cor-
rectly when it is stored and installed.
The machine must be stored at a temperature between -25°C and 55°C.
NOTE. Do not dispose of the packing materials in the environment.
Once you have decided where to install the unit (consult the relative sections of this
manual), proceed by unpacking it in the following way:
1. Cut off the two nylon straps.
2. Open the top side of the box.
3. Take hold of the unit and lift it fully out of the box.
4. Remove the side protections and take off the nylon wrapping.
UNITS OPENING
1. Remove the screws and take off the front panel.
2. Procede with the installation on procedure.
3. Close everything.
ELECTRICAL CONNECTIONS
If the unit is supplied with a plug, as indicated on the wiring diagrams, it is con-
nected by simply inserting the plug of the interior unit into a mains socket. The
exterior unit draws its power from the interior one.
Comply with the instructions given in the “Electrical connections” section for the
other units.
NOTE: The power cable’s socket must be equipped with a regulation ground con-
tact so as to comply with the indications in the technical specifications table.

INSTALLATION OF THE UNIT
Choice of the installation site. In compliance with the con-
ditions, position the unit as low as possible, but always ensu-
re that there is 10 cm free space above it. Before fixing the
unit to the wall, make sure that this latter is able to bear the
weight of the machine, that the air flow is not obstructed by
curtains or other, and that the position is able to guarantee
that the ais apreads in an optimal way around the room.
Installation. Once the position of the interior unit has been
chosen, use the fixing plate (Fig.1) as a template so as to
identify the exact positions of the expansion plugs and the
hole that passes through the wall.

Models 30-V / 40-V
WIRING DIAGRAMS
To allow the conditioner to operate, the electrical connections must be made as indicated on the wiring diagrams sup-
plied with the machine. It is essential for the units to be connected to an efficient ground ground system. The
manufacturer declines all liability for failure to comply with this precaution.
NOTE: Refer to the wiring diagrams supplied with the machine for all work involving the electrical system.

MACHINE INSTALLATION
Proceed as described below:
1. Place the plate on the wall at the appropriate height and fix it in place, keeping it
as horizontal as possible (use a level).
2. Mark the positions of the fixing holes.
3. Using a drill and a Ø 8 mm bit, make the holes and insert the expansion plugs.
4. Choose the side on which the connection pipes must exit. It is advisable to use
the rear outlet on the right. Consult the “OTHER POSITIONS FOR INSTALLATION”
section.
5. Make a Ø 70 mm hole in the wall (Fig.2), slightly slanting towards the outside.
Now begin to drill on one side of the walll (A) and terminate from the opposite side
(B) to prevent the wall from crumbling.
6. Using the relative screws, fix the plate in the four holes made previously.
Fig.2
The plastic casing of the unit has pre-cut holes which can be removed if necessary, so as to route the cooling pipes
and cables.

OTHER POSITIONS FOR INSTALLATION
The unit can also be installed in the following positions:
1. With outlet at the rear left
2. With outlet at the side, on the left
3. With outlet at the side, on the right
4. With outlet pointing downwards
Proceed as indicated below to install the unit with the outlets at the rear left:
1. Make the Ø 70 hole near the left-hand outlet.
2. Make the wet connections between the pipes of the interior unit and those of
the exterior unit.
3. Position the pipes in the housing in the interior unit and fix them in place with
the relative plate as shown in the figure alongside (Fig.5).
Proceed as described below to install the unit with outlets at the side or pointing
downwards:
1. Detach the pre-cut plate (Fig.6) from the direction required.
2. Turn the pipes carefully to the required direction.
3. Make the cooling pipe connections between the pipes of the interior unit and
those of the exterior unit.
MACHINE INSTALLATION
7. Raise and carefully turn the pipe sections required for connecting to the exte-
rior unit and route them through the Ø 70 mm hole.
8. Route the condensation drain pipe through the same hole. Depending on per-
sonal requirements, this pipe can also be routed in other directions, so long as it
slopes sufficiently to allow the condensation to drain away properly.
9. Hang the interior unit securely on the hooks of the fixing plate.
10. Make sure that the unit has been firmly fixed by moving it towards the right
and left.
NOTE: To make it easier to fix the unit to the plate, keep the lower part of the unit
raised then lower it perpendicularly into position, accompanying the sheath as
this is done (Fig.3).
The installer’s experience will allow all these operations to be perfected to suit the
specific requirements.

DESCRIPTION OF THE OPERATING MODES
The following operating modes are available:
Operation in the Cooling mode: this function is obtained by pressing the “MODE” key until the relative “COOL” symbol
appears on the display. The unit begins to operate if the temperature setting is less than that of the environment.
Available operating range: 18-30°C; preset temperature 25°C.
Ventilation mode: allows the air to circulate around the surrounding room in the automatic mode, at the speed set by
means of the Fan key: Auto, High, Medium or Low.
Operation in the Heating mode: this function is obtained by pressing the “MODE” key until the relative “HEAT” symbol
appears on the display. The unit begins to operate if the temperature setting is higher than that of the environment.

tor comes on.
