1.4 USES

RS units are dehumidifiers to be installed combined to radiant systems, which allow to dehumidify, or to cool and dehumidify air.

Its use is recommended within the functioning limitations indicated in this manual.

Place the unit where there are not explosion or fire dangers, neither in vibrating areas or in presence

of electro-magnetical fields. Furthermore, do not operate in ways which differ from those indicated

and do not underestimate safety operations.

not possible to elude during the project neither to reduce. Each operator should be aware of the

residual risks in this unit, in order to avoid accidents.

Residual risk areas:

-Short circuit or fire caused by short circuit risk;

-Explosion danger because of the presence of under pressure circuits or pollution due to the refrigerant gas in the circuit;

-Burn danger because of high temperature pipes;

-Shearing risk

2PRODUCT DESCRIPTION

RSV are vertical dehumidifiers for in-wall installation, RSO –RSE are horizontal

dehumidifiers ductable for ceiling installation. They are suitable for residential and

commercial applications with a high latent load, where it is required functioning 24

h/day.

They are recommended in those buildings where cooling is realized through radiant

systems, such as floor, walls or ceilings.

RS _ A (isothermal) dehumidifiers, if correctly supplied with water at 15°C can

dehumidify the air without changing the temperature. This is possible thanks to the

presence of two heat exchangers which pre-cool the inlet air and post-cool it after the

dehumidifying process.

RS _ I (hybrid) if correctly supplied with water at 15°C can dehumidify the inlet air without changing the temperature; they have also

an ambience thermo-hygrostat and a water plates condenser, which allow the unit to supply cold air if required.

The use of exclusive high-quality refrigerant, hydraulic and electrical components make RS dehumidifiers the state of art in terms of

efficiency, reliability and sound emitted level.

2.2 STRUCTURE

The unit is realized with pre-painted white steel panels; structural internal elements are realized in electro-galvanized steel, for a

further corrosion protection. Bolts and screws are made of non-oxidable material, INOX or carbon steel with superficial treatment of

passivation. Panels are covered with synthetic open-cells polyurethane material, in order to ensure the maximum phono-absorbent.

The unit is completely closed and the access is possible only from the front panel for vertical models and from the side for the

horizontal ones. The access to the compressor area is easier thanks to the removable panel, which allows operations without

obstacles.
