6.3 Installation
The units are shipped from the factory already tested and they need only the electrical and hydraulic connections for in-
stallation, except for the "LC" (condenserless), "LC/HP" (reversible condenserless), "LE" (motocondensing) and "LE/HP"
(reversible motocondensing) versions for which the refrigerant connections with the remote exchanger must also be made.
6.3.1
Positioning the units
The units must be positioned in covered areas where temperatures are kept above 4°C.
Make sure the support can bear the weight of the unit (refer to the documentation supplied with the unit).
Units installed on the ground transmit a low level of vibration. It is in any case advisable to lay a strip of hard rubber between
the base and the support surface (floor or concrete slab).
If better isolation is required, it is advisable to use the anti-vibration mounts that are available as accessories.
6.3.2 Positioning the remote heat exchanger
To position the remote heat exchanger, see the relevant manual.
6.3.3
Noise attenuation
The units are designed and built paying particular attention to keeping down noise emission during operation.
In addition to the standard versions, there are "LN" (Low Noise) versions for which further devices are used for lower noise
emission.
Correct installation for both the place and the components, as shown in the relevant chapter, avoids resonances, reflections
and vibrations that can be particularly bothersome.
If, after following the instructions above, further attenuation is required, the use of acoustic barriers is a valid solution.
It is essential to be careful that any work done to soundproof the unit does not affect its correct installation or its correct
operation.
That is why it is necessary to avoid limiting the service spaces.
6.3.4
Minimum distances
The service spaces to comply with are shown on the dimensional drawings attached to the documentation of the unit.
It is, in any case, advisable to leave sufficient space between the units to allow removal, if necessary, of their larger compo-
nents such as the exchangers, compressors or pumps.
As for a possible remote heat exchanger, see the relevant documentation.
We reserve the right to make changes without any prior notice.
