INSTALLATION

During installation or whenever work must be carried out on the unit, it is essential to strictly follow the instructions in
this manual, comply with the directions on the unit and in any case take all necessary precautions.
The pressures in the refrigerant circuit and the electrical components can create risky situations
during installation and maintenance work.

5.1 Dimensions and weight

In order to correctly position the unit, please refer to the dimensional drawing supplied with the order confirmation for
its size and weight.

5.2 Installation site

The following should be taken into account to establish the best place to install the unit and the relevant connections:
- size and origin of the aeraulic ducts;
- size and origin of the hydraulic piping;
- location of the power supply;
- accessibility for maintenance or repair operations;
- load-bearing capacity of the support surface;
- ventilation of the air-cooled condenser;
- orientation and exposure to solar radiation. Keep the condensing coil out of direct sunlight as far as possible;
- direction of prevailing winds. Do not position the unit in a such way that prevailing winds can cause air recirculation
at the condensing coil;
- type of surface. Do not position the unit on dark coloured surfaces (e.g. tarred surfaces) so as to avoid
overtemperatures during use;
- possible reflections, resonances and acoustic interactions with elements outside the unit.
Pay attention to the presence of flues, drains, vents and to the stale air of other systems. Air can be
sucked from the fresh air damper and through the supply unit in the rooms to be air conditioned.
All the models in the range are designed and built for outdoor installation (terraces, gardens). They must therefore
not be installed under canopies or near plants (even if these would cover only part of the unit), in order to avoid the
possibility of air recirculation.
It is obligatory to observe the clearances specified in the dimensional diagram of the unit.
If the unit is installed in particularly windy areas, windbreaks must be installed to prevent
malfunctioning of the unit.
During the defrost cycle, units in heat pump operation allow water to flow out that freezes with sub-
zero temperatures. Although the unit is installed perfectly horizontal, make slopes in the support
surface to direct the defrost water into drains, wells or in any case to places where there is no danger
of accident.
The unit is filled with refrigerant gas, classified as A2L (mildly flammable).
