1.9 PACKAGING AND TRANSPORT
The units are supplied for transport fixed on a wooden pallet and placed in cardboard boxes. To facilitate movement, the units are equipped with a
wooden bench and hooks on the base that allow them to be lifted and positioned on the installation site. The unit can be stored in a room protected
from atmospheric agents with temperatures not below 0 ° C, up to a maximum of 40 ° C.
1.10 RECEIPT, CONTROL AND HANDLING
The unit is shipped fully pre-charged with refrigerant gas in the circuits and with non-freezing oil in the compressors. Under no circumstances can
water be present in the hydraulic circuits, since after testing the unit is carefully emptied. Upon arrival, the customer is required to inspect the unit
also in internal areas to verify that it has not been damaged during transport; the unit left the factory in perfect condition. Otherwise, it is necessary
to immediately retaliate against the carrier by reporting the extent of the damage in detail on the bill, producing photographic evidence of the
apparent damage and notifying any apparent damage to the shipper by means of a registered letter. if he has provided for the shipment himself. It
is necessary to be very careful in handling the units during unloading and positioning, in order to avoid damage to the casing and to the more
delicate internal components such as compressors, exchangers, etc. In any case, keep the unit in a horizontal position without tilting it. All the
information about the necessary precautions to prevent damage to the unit and the indication of the weight of the same, are shown on the
packaging. The materials that make up the packaging can be of various kinds such as wood, cardboard or polyethylene (plastic). It is good practice
to send them for disposal or recycling through specialized companies to reduce their environmental impact. in order to avoid damage to the casing

2INSTALLATION
2.1 INSTALLATION CONDITIONS
The unit must be installed according to national and local standards that regulate the use of electrical devices and according to the following
indications:
-install the unit inside residential buildings with ambient temperatures between 0 ° C and 45 ° C;
-avoid areas near sources of heat, steam, flammable and / or explosive gases and particularly dusty areas;
-install the unit in a place not subject to frost (the condensation water must be drained not frozen, at a certain inclination, using a siphon);
-do not install the unit in areas with a high relative humidity (such as a bathroom or toilet) to avoid condensation on the external surface;
-choose an installation site where there is sufficient space around the unit for the connections of the air ducts and to be able to carry out
maintenance operations;
-the consistency of the ceiling / wall / floor where the unit will be installed must be adequate for the weight of the unit and not cause
vibrations.
The environment chosen for the installation must contain:
- connections of the air ducts;
- 230V single-phase electrical connection
- connection for condensate drain
2.2 POSITIONING UNIT
Ceiling mount
To mount the unit on the ceiling, you need:
Fix the unit to the ceiling, using the brackets, using suitable
anchoring systems (dowels, chains…) and check the leveling
with the help of a level.
Keep the unit away from the ceiling at least 10mm;
Do not mount the unit with the sides in direct contact with the
walls to avoid possible contact noises, insert rubber or neoprene
strips in this case.
Ensure sufficient space for carrying out maintenance activities:
the opening of the unit cover (from below) must be guaranteed.

Manual 2.0 RINNOVA DUCT
2.3 CONDENSATE DRAIN 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 drain to the
hydraulic system (drain); Furthermore, to allow the
condensate water to drain correctly and avoid air sucking in,
the condensate drains must be equipped with a special
siphon to be supplied and laid by the installer;
The condensate drain comes out as standard in the rear part
of the unit where there should be the hole in the wall as
shown alongside;
If it is impossible to take the condensate drain outside, it is
possible to exit on the right side of the unit as shown in the
figure alongside;
To install the condensate drain, comply with the following
rules:
give a slope of at least 2% to the exhaust pipe;
provide for the possibility of disconnecting the
drain hose for any maintenance (in particular in the
case of ceiling installation);
make sure that the discharge end of the pipe is at
least below the water level of the siphon;
make sure that the siphon is always full of water.
The H dimension as per the attached image must
be at least H = 50mm;

3.2 ASSEMBLY OF EXTERNAL GRIDS
Once the holes have been made, the plastic sheets supplied
must be inserted inside them.
Roll up the sheet and insert it into the hole, paying attention
to the seam A which must always be positioned upwards.
Cut off any excess part of the tube using a normal cutter.
To position the external grids, proceed as follows:
- attach the chains to the ends of the springs;
- fold the external shutters on themselves;
- insert the arm into the hole until the shutter completely
protrudes outside, keeping the end of the chains with the
other hand to avoid accidental falls;
- reopen the shutter outside the hole;
- rotate the shutter so as to bring the flap in vertical position
C checking that the closing mechanism works;
- pull the chains by tensioning the springs;
- cut the chain stitches in
excess.
- fasten the hook of the chain to the wall B.
Use only the grids supplied, or grids that maintain the same
characteristics.
The shutters must be positioned with the blade vertically.
The shutters are different. It is necessary to distinguish the
one to be positioned on the return from the one to be
positioned on the supply, according to the opening direction
of the blades.
Once the installation of the grilles has been completed, check
their opening (towards the inside of the duct for the "IN"
suction grille and towards the outside of the duct for the
"OUT" exhaust grille).
Keep in mind that the grilles open when the outside air flow
is activated to allow the cooling or heating function.
For their testing it is therefore essential to operate the air
conditioner to cool or heat

5.7 NIGHT WELLNESS FUNCTION
With the appliance on and the cooling or heating mode selected, pressing the button allows you to perform multiple
functions aimed at maximizing the silence of the appliance, saving electricity and regulating night-time well-being.
In this mode, the fan operation is set to minimum speed.
This feature should be activated immediately before falling asleep
• In cooling, the set temperature set is increased by 1 ° C after one hour and by a further ° C after 2. After the second
hour the temperature set setting is not further altered and after another 6 hours the appliance is placed in stand-by.
• In heating, the set temperature is decreased by 1 ° C after one hour and by a further ° C after 2 hours. After the
second hour, the temperature setting is not further altered and after another 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
excluded at any time (ideally upon waking up) by pressing the button again.
In case of simultaneous setting of the Timer function, the appliance will switch off after the set time has elapsed.
Night wellness
5.8 DEHUMIDIFICATION FUNCTION
Using this mode, the appliance dehumidifies the room. The activation of this function is therefore particularly useful
in mid-seasons, that is to say on those days (such as rainy days) in which the temperature is all in all pleasant, but
excessive humidity makes you feel a certain sense of discomfort. In this mode, both the ambient temperature setting
and the fan speed setting are ignored, which always corresponds to the minimum. In this mode it is normal for the
appliance to operate intermittently
