2. INSTALLATION
2.1 INSTALLATION CONDITIONS
The unit must be installed based on national and local regulations governing the use of electrical devices
and based on the following indications:
• install the unit inside residential buildings with room temperature between 0°C and 45°C;
• avoid areas near sources of heat, steam, inflammable and/or explosive gases and particularly dusty areas;
•install the unit in a place that is not subject to frost (the condensation water must be discharged not frozen, at
a certain slope, using a trap);
•do not install the unit in zones with a high relative humidity rate (such as bathroom or toilet) to avoid
condensation on the external surface;
•choose a place of installation where there is enough room around the unit for the connections of the air ducts
and to perform maintenance activities;
•the consistency of the ceiling/wall/floor where the unit will be installed must be suitable for the weight of the
unit and not cause vibrations.
The installation position of the unit, in order to obtain the best operating efficiency and to avoid faults or hazardous
conditions, must have the following requirements:
- Respect the spaces indicated in the figure.
- The wall on which the unit is to be fixed must be sturdy and suitable to support its weight.
- It must be possible to leave space around the unit for maintenance.
- There must be no obstacles to the free circulation of air in the upper intake area (curtains, plants, furniture) or
in the front air outlet area; this could cause turbulence that would inhibit the correct operation of the appliance.
- The unit can be placed on the floor or suspended.
- The appliance is rated IPX0, so it is not suitable for outdoor installation.
- Check that there are no structures or installations (beams, pillars, water pipes, electric cables, etc.) at the
points where you intend to drill the holes that would prevent the necessary holes from being drilled. Check that
there are no obstacles to the free circulation of air through the holes you are going to make (plants and their
foliage, slats, shutters, grills or grates that are too thick, etc.).
- The appliance must not be in a position where the air flow is aimed directly at people nearby.
- The appliance is not directly above an electrical appliance (television, radio, refrigerator, etc.), or above a heat
source.
The room chosen for installation must have:
- Outdoor air duct connections;
- 230V single-phase electrical connection;
- Connection for the condensate discharge.

ASPIRCOMFORT PRO X 380V
2.2 UNIT POSITIONING
TYPE OF INSTALLATION
The unit requires two Ø162 holes to be drilled as indicated on the drilling template in order to operate;
The maximum permissible hole length is 1 m and no bends may be made. It is necessary to use the grids supplied,
or grids with the same characteristics.
Drilling into the wall must be carried out using appropriate equipment that facilitates your work and avoids
excessive damage or disturbance to your customer. The best tools for drilling large diameter holes in walls are
special drills (called 'core drills') with high torque and adjustable rotation speed depending on the diameter of the
hole to be drilled and the material. To prevent the spread of large quantities of dust and debris in the environment,
core drills can be coupled to suction systems consisting essentially of a hoover to be connected to an accessory
(such as a suction cup) to be placed close to the drill bit.

11
ENGLISH
ASPIRCOMFORT PRO X 380V
Proceed as follows to perform drilling:
- Place the drilling template supplied against the wall,
observing the minimum distances: from the ceiling, floor
and side walls indicated on the template itself, which can be
held in place with adhesive tape.
- Using a small drill or an awl, carefully mark out the centre
of the various holes to be drilled before making them.
- Drill two holes for the air inlet and outlet using a drill bit.
These holes must be drilled with a slight downward slope to
prevent water from flowing back through the pipes.
Most of the material removed is ejected outwards, so care
must be taken to ensure that it does not strike people or
objects below as it falls. In order to avoid breaking the
external plaster as much as possible, the final part of the
hole should be drilled very carefully, loosening the pressure
on the core drill a little.
Drill the 6 holes for anchoring the wall mounting bracket as
indicated on the drilling template.
The greatest weight of the appliance is on the right-hand
side, so it is preferable to secure a firmer fixing on this side.
The 6 dowels supplied require a hole diameter of 8 mm.
In any case, a careful examination of the characteristics
and consistency of the wall is necessary to determine the
number of fixings to be made and the possible choice of
specific anchors for particular situations. In the case of
installation on plasterboard or walls with a low consistency,
provide a bracket on the outside, if necessary, that can
guarantee the safe support of the machine.
The manufacturer cannot be held responsible for any
underestimation of the structural consistency of the
anchorage provided by the installer. We, therefore, invite you
to pay the utmost attention to this operation. Do not install
the unit with the sides directly touching the walls to avoid
possible noise from contact, insert rubber or neoprene
strips in that case.
Provide enough space to perform maintenance activities: it must be possible to open the cover of the unit (front).

12
ENGLISH
ASPIRCOMFORT PRO X 380V
POSITIONING ON MOUNTING BRACKET
After checking that the fixing bracket is firmly fixed to the wall and that the electrical and condensate discharge
connections have been made, you can attach the air conditioner. Lift it up by gripping the sides of the lower base
until the bracket engages in the points provided on the unit. To facilitate the docking operation you can tilt the unit
slightly towards you.
Direct electrical connection (by disconnecting the power cable with plug) and fixing the condensate discharge
must be carried out with the appliance away from the wall by means of a wooden wedge or similar object.
At the end of the work, carefully check that no cracks remain behind the back of the unit, especially in the area of
the air inlet and outlet ducts.
To increase installation safety, the machine can be anchored to the wall by means of a special anti-lifting bracket
on the underside of the machine. The drilling position is shown on the installation template.

ASPIRCOMFORT PRO X 380V
2.3 CONDENSATE DISCHARGE CONNECTION
Due to the cooling system, the condensate discharge pipe (Ø16mm internal not supplied) must be connected to
the pipe at the rear of the unit. For this reason, it is essential that the discharge line has a minimum slope of at
least 3% at each point. The tube to be used can be rigid or flexible with a minimum internal diameter of 16 mm. If
the line enters a sewage system, siphoning must be carried out before the pipe enters the main discharge. This
siphon must be at least 300 mm below the inlet of the appliance.
If the drainage line flows into a container (tank or other), it must be ensured that the container is hermetically
sealed and above all that the drainage pipe does not remain immersed in water.
The hole for the condensate pipe must always have an outward slope.
The exact position of the pipe opening in relation to the machine is defined on the drilling template.
Take care in this case that the water expelled does not cause damage or inconvenience to property or persons.
During the winter period this water can cause ice sheets to form outside.
When connecting the condensate discharge, take care not to crush the rubber hose.
If necessary, the condensate tray can be emptied through a safety drain on the base of the appliance.
N.B.: for the installation of the condensation discharge pipe towards the outside, it is recommended to cover the
internal pipe supplied with the appliance with anti-condensation insulation with an internal diameter of 10 mm
(see ref. 2 in the figure).
The insulation must be inserted up to the mouth of the external condensate discharge pipe embedded in the wall.

3.2 INSTALLATION OF EXTERNAL GRILLES
Once the holes have been drilled, the plastic sheets supplied must
be inserted into them.
Roll up the sheet and insert it into the hole, paying attention to the
seam line A, which must always be positioned upwards.
Cut off any excess part of the tube using a standard cutter.
To position the external grilles, proceed as follows:
- attach the chains to the end of the springs;
- fold the external dampers back on themselves;
- insert the arm into the hole until the damper protrudes completely
outwards, holding the end of the chains with the other hand to
prevent accidental falls;
- re-open the damper on the outside of the hole;
- turn the damper so that the flap is in the vertical position C and
check that the closing mechanism works;
- pull the chains by tensioning the springs;
- use a wire cutter to cut off the excess chain links;
- fix the chain hook to the wall B.
Use only the grills supplied or grills with the same characteristics.
The dampers must be positioned with the flap vertical.
The dampers are different. A distinction must be made between the
one on the inlet and the one on the outlet, depending on the direction
of opening of the flaps.
Once the installation of the grilles is complete, check their opening
(towards the inside of the duct for the intake grill "IN" and towards
the outside of the duct for the exhaust grill "OUT"). Please note that
the grilles open when the flow of outside air is activated to allow the
cooling or heating function. For their testing, it is therefore essential
to operate the air conditioning system for cooling or heating.
