Modular L Smart
4.1.6. Environmental conditions
Modular L Smart heat recovery units are designed for use in indoor environments, installed on the ceiling. The unit cannot operate
in environments containing explosive material and with a high concentration of dust.
Thanks to its modularity, each machine is able to adapt to different needs in terms of air flow and thermodynamic treatments.
The optimised choice of every detail, the search for maximum efficiency in each component, the adoption of specific materials and
constructive solutions transform environment friendliness and energy savings into valid and advanced technological solutions.
4.1.7. Environmental contamination
Depending on the installation operating environment, specific regulations must be followed and all the necessary precautions must
be taken to avoid environmental issues (a system that operates in a hospital or chemical environment can have problems different
from those in other sectors, even from the point of view of disposal of consumable parts, filters, etc.).
It is mandatory for the buyer to inform and train workers regarding proper procedures.
4.1.8. Noise
It should be noted that every environment has its own acoustic characteristics that can greatly affect the noise perceived during
operation, therefore it is necessary to consider the noise data provided as a point of reference, while it is up to the buyer to perform
specific sound level measurements at the installation site and during the machine's actual use.
4.1.9. Ceiling and air duct specifications
The ceiling where you plan to install the machine must be:
• Perfectly flat and without roughness.
• Vibration resistant.
• Able to support the weight of the equipment considering an appropriate safety margin.
The equipment installed on the ceiling can adapt easily to the presence of a false ceiling.
In fact, without sufficient space for up-and-over door opening, the inspection door can be transformed into a panel able to slide on
accessory rails (optional).
If provided, the air ducts must be connected directly to the machine, taking care to insert a suitable anti-vibration system between
the machine itself and the duct. When assembly is completed they must not be taut, in order to avoid damage and transmission of
vibrations.
To ensure the seal of the connections and the integrity of the machine, it is essential that the air ducts be supported by special
brackets that do not weigh directly on the machine.
Outside air temperature • -5°C to +46°C without pre heating heating coil
• -25°C to +46°C with pre heating electric coil for size 04 & 06
• -20°C to +46°C with pre heating electric coil for size 02 & 03
& 05 & 07
Operating environment temperature +5°C to +46°C
Temperature of the environment with the machine off (e.g.,
storage, transport, etc.) -40°C to +60°C
