6 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.
6.1 Dimensions and weight
In order to correctly position the unit, in compliance with its size, weight and distance requirements, please refer to the di
-
mensional drawing supplied with the unit documentation.
6.2 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 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 overtemperatu
-
res during use;
-
possible reflections, resonances and acoustic interactions with elements outside the unit.
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 tem
-
peratures. 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.
In areas where there are heavy snowfalls, the place of installation must be chosen so that the snow cannot in any way
interfere with the operation of the unit:
- build a wide canopy;
- build a base;
-
install the unit in a fairly high position off the ground so that it will not be covered with snow.
To make installation easier, the option “Base frame (H=500 mm) with rubber anti-vibration mounts” is available in the cata
-
logue.
