ENGLISH
ASPIRCOMFORT PRO X 460H
2.3 CONDENSATE DISCHARGE CONNECTION
Due to the thermodynamic heat recovery system of the dehumidification coils, the humidity contained in the
indoor air condenses inside the unit.
For the correct operation of the heat recovery unit, it is therefore necessary to connect the condensate discharge
to the hydraulic system (drain); furthermore, in order to allow the correct flow of the condensate water and to
avoid air suction, the condensate discharges must be equipped with a special siphon to be supplied and installed
by the installer;
Condensate discharge exits as standard to the rear of the unit where there should be a hole in the wall as shown
opposite;
If it is not possible to take the condensate discharge outside, it is possible to exit on the right side of the unit using
the pre-cut hole on the side;
For installation of the condensation discharge, follow these rules:
• set up a slope of at least 2% to the discharge pipe;
• allow the possibility of disconnecting the discharge pipe for any
maintenance (especially with ceiling installation);
• make sure that the discharge end of the pipe is at least below the level of
the trap water;
• make sure that the trap is always full of water;
• the H dimension as shown in the attached image must be at least H=50mm;

3.2 INSTALLATION OF EXTERNAL GRILLES
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.

SWITCHING THE UNIT ON AND OFF
In order to operate the appliance using the remote control or the touch screen display, it is
necessary to either switch on the main switch which has been provided on the power supply line
(the technician who installed the appliance will be able to be more precise about its position),
or insert the appliance's power plug into the system's socket. Once the described operations
have been carried out, by prolonged pressure (3 seconds) on the symbols on the touch screen
display, or with the remote control, it is possible to manage the system. In order to transmit
commands to the indoor unit, the front of the remote control must be turned towards the
display of the indoor unit. Receipt of the command is confirmed by the buzzer sounding a note
and being shown on the display. The maximum distance at which commands can be received
is approximately 8 metres.
Using the stand-by button, you can switch the appliance off or on. The appliance's control
system has a memory, which means that all settings will not be lost either when the appliance
is switched off or in the event of a power failure. This button is used to activate and deactivate
the device for short periods.
In the event of prolonged standstill of the appliance, it must be switched off by disconnecting
the main switch or removing the plug from the socket.
TEMPERATURE SET MODIFICATION
On the display there are buttons for selecting the desired temperature of the unit;
Whenever the set temperature is changed, the display will also show the change in set point
required.
FAN SPEED MODIFICATION
By pressing this button sequentially, the power supplied by the appliance can be set to 5
settings: Minimum, Medium, Maximum, Dual Power and Automatic.
The higher the power setting, the greater the output of the appliance, but the quieter it is.
The Dual Power function (visible by the flashing of the 3 speed bars on the display and the
scrolling of the 7 bars, red or blue, on the digital thermometer), available only in heating and
cooling mode, provides an overboost for 30 minutes.
The controller then inhibits the function and switches to automatic operation.
By setting the Automatic choice (visible through the scrolling of the 3 speed bars on the display)
the on-board microprocessor automatically adjusts the power, keeping it higher the greater
the difference between the room temperature and the set temperature. In dehumidification
only and night wellness mode, power control is not possible as the appliance can only be
operated at minimum power.
AUTOMATIC FUNCTION
By setting this function, the appliance sets itself up so as to achieve optimal comfort in the
air-conditioned room. Depending on the set temperature, the air conditioner automatically
selects the operating mode (cooling, or heating), and the ventilation speed according to the
room temperature and the detected air quality.

VENTILATION-ONLY FUNCTION
When this function is activated, the compressor is never switched on and the appliance has no
effect on either the temperature or the humidity of the air in the room. It is possible to select
the fan speed.
NIGHT WELLNESS FUNCTION
With the appliance switched on and the cooling or heating mode selected, pressing the button
allows multiple functions to be performed to maximise the quietness of the appliance, save
electricity and regulate night wellness.
In this mode, fan operation is set to minimum speed.
This function should be activated immediately before falling asleep.
• In cooling mode, the set temperature set is increased by 1 °C after one hour and by a further
1 °C after 2 hours. After the second hour, the temperature set is not altered any further and
after a further 6 hours the appliance is placed in stand-by.
• In heating mode, the set temperature is reduced by 1 °C after one hour and by a further 1
°C after 2 hours.
After the second hour, the temperature set is not altered any further and after a further 6
hours the appliance is placed in stand-by.
This function is not available for dehumidification-only, ventilation-only and economic
automatic operation and can be overridden at any time (ideally when waking up) by pressing
the button again.
If the timer function is set at the same time, the device will switch off after the set time has
elapsed.
DEHUMIDIFICATION FUNCTION
Using this mode, the appliance dehumidifies the room. Activating this function is therefore
particularly useful in the mid-seasons, i.e. on days (such as rainy days) when the temperature
is pleasant, but the excessive humidity makes you feel a certain sense of discomfort. In this
mode, both the room temperature setting and the fan speed setting are ignored and always
correspond to the minimum. In this mode it is normal for the appliance to operate intermittently.
CHANGE OF SEASON
The change of season must be carried out from the keyboard;
Press and hold the season change button for at least 3 seconds to change the season status;
This operation must be carried out in order to activate the correct logics.
