Page 7: Residual Risks
1.6 Residual Risks A residual risk is any hazard that cannot be fully reduced by design and protective techniques, or a potential hazard that is not obvious. ATTENTION This manual indicates any operation that may generate a hazardous situation as well as the precautionary measures to be observed in each case. - Page 8 Whilst the unit has been designed to minimize any risk posed to the safety of people who will interact with it. It has not been technically possible to eliminate completely the causes of risk. It is therefore necessary to refer to the require- ments and symbolism below.

Page 12: Technical Characteristics
2. TECHNICAL CHARACTERISTICS 2.1 Introduction Any occupied room requires the correct supply of fresh air and, at the same time, the control of the internal thermo- hygrometric conditions, through the recovery of energy from the air extracted from the room, by means of static counter- flow heat recoveries, the level of well-being of the occupants is guaranteed, both in summer and winter. -
Page 13: Air Filters
2.4 Air filters ≥ 50% (F7) rigid bag filters in fresh air. Both types of filters are mounted on slides equipped with gaskets to ensure effec- tive sealing. Their position, upstream of the internal components, also guarantees their protection. 2.5 Fans The units are equipped with high efficiency plug-fan type fans with built-in brushless EC motor. -

Page 18: Operating Mode
7. OPERATING MODE 7.1 Winter operating mode The return air from the room, with a higher thermal load than the fresh air, crosses the plate heat exchanger, where it gives up part of its thermal load and cools down before being exhausted. The fresh air, with a lower thermal load than the return one from the room, crosses the plate heat exchanger in the opposite direction and heats up before the introduction into... -
