5.3 Installation
The units are sent from the factory already tested and they need only the electrical and hydraulic connections for instal-
lation, except the "LE" (motocondensing) versions and the "LE/HP" (reversible motocondensing) versions for which the
refrigerant connections with the remote exchanger must also be made.
5.3.1 External positioning
A solid base on which to position the unit must be created.
This base must be perfectly flat and horizontal. Its dimensions must be adequate for those of the unit.
The slab must be:
- made in a suitable foundation about 15-20 cm higher than the surrounding ground;
- flat, horizontal and able to bear at least 4 times the operating weight of the unit;
- at least 30 cm longer and wider than the unit.
Although the units transmit low levels of vibration to the ground, it is advisable to lay a strip of hard rubber between the base
frame and the support surface.
If better isolation is required, it is advisable to use the anti-vibration mounts that are available as accessories.
In the event of installation on roofs or intermediate floors, the unit and pipes must be isolated from the walls and ceilings.
The units should not be positioned near private offices, bedrooms or areas where low sound emissions are required.
It is also advisable not to install the units in narrow passages or small spaces, in order to avoid reverberations, reflections,
resonances and acoustic interactions with elements outside the unit.
Units equipped with standard coils (copper-aluminium) should not be installed in an environment where there is an aggres-
sive chemical atmosphere, in order to avoid the risk of corrosion.
Particular attention should be given to atmospheres containing sodium chloride, which worsen corrosion due to galvanic
currents; a unit with untreated coils must absolutely not be installed in a marine environment.
For installations in marine environments, in the vicinity of animal farms or in heavily polluting industrial areas, it is necessary
to order coils with anticorrosive surface treatments.
In any case, please contact our sales department to define the most suitable solution.
