PACKING AND TRANSPORT
The units are supplied for transport fixed on a wooden pallet and inserted in cardboard boxes. To facilitate movement, the units are equipped with a
wooden pallet and hooks on the base which allow them to be lifted and positioned on the installation site. The unit can be stored in a place protected
from atmospheric agents with temperatures not lower than 0 °C, up to a maximum of 40 °C.
RECEPTION, CONTROL AND HANDLING
The unit is shipped completely 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
the 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 take
immediate recourse against the carrier, reporting the extent of the damage in detail on the document, producing photographic evidence of the apparent
damage and notifying any apparent damage to the shipper by registered mail. The manufacturer assumes no responsibility for damage due to transport,
even in if he did the shipping himself.
Great care must be taken in handling the units during unloading and positioning on site, 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 horizontal without tilting it. All the indications regarding the
precautions necessary to ensure that no damage is done 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.

Page10
CONDENSATE DRAIN CONNECTION
Due to the thermodynamic heat recovery system of the
dehumidification coils, the humidity contained in the internal air
condenses inside the unit.
For the correct functioning of the heat recovery unit, it is
therefore necessary to connect the condensate drain to the
hydraulic system (drain); Furthermore, to allow the correct
outflow of the condensate water and avoid air suction, the
condensate drains must be equipped with a special siphon to
be supplied and installed by the installer;
The condensate drain comes out as standard at the rear of the
unit where there should be a hole in the wall as shown
alongside;
If it is impossible to bring the condensate drain outside, it is
possible to exit on the right side of the unit using the pre-cut
hole on the side;
For the installation of the condensate drain, comply with the
following standards:
•give the drain pipe a slope of at least 2%;
•provide for the possibility of disconnecting the drain
pipe for any maintenance (particularly in the case of
ceiling installation);
•make sure that the discharge end of the hose is at
least below the water level of the siphon;
•make sure that the siphon is always full of water.

completely the damper outside maintaining
the end of the chain stitches with the other hand to avoid
accidental falls;
- reopen the damper outside the hole;
- rotate the damper so as to bring the flap in
vertical position C checking that the mechanism
closing functions;
- pull the chains by tensioning the springs;
- cut the links of the chain stitches with a nipper
excess.
- fix the hook of the chain to the wall B.
Only use the grills provided,
or grids that maintain the same
characteristics.
The dampers must be positioned with the fin vertically.
Shutters are different. It is necessary to distinguish that
to be positioned on the intake from the one to be positioned on
the delivery, based on the opening direction of the flaps.
Once the installation of the grilles is completed, check their
opening (inwards the duct for the "IN" suction grille and
towards the outside of the duct for the "OUT" exhaust grille).
Note 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
