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.

1.5 RESIDUAL RISK AREAS

Due o he peculiar func ionali y of he uni , in some areas of i , here are residual risks which was

no possible o elude during he projec nei her o reduce. Each opera or should be aware of he

residual risks in his uni , in order o avoid acciden s.

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;

-Slash danger.

1.6 GENERALS SAFETY RULES

1.6.1 Safety clothes

Operators should wear safety equipment

such as gauntlet, helmet, safety glasses,

safety footwear and cap for protection

from the noise.

1.6.2 Fi e extinguishe and fi st

aid

2PRODUCT DESRIPTION

RSV models are vertical dehumidifiers to be housed, while RSEO / RSE

are ductable horizontal dehumidifiers for drop ceiling, thought for the

use in residential and commercial ambiences with a high latent charge,

where the functioning 24 h/day is required.

They are recommended in those buildings where the cooling is realized

through radiant systems, such as floor, walls or ceilings.

RS dehumidifiers combine technical solutions with a pleasant aesthetic

design and, thanks to the external covers (optional) they can be

installed at sight .

RS _ A (isothermal) dehumidifiers, if correctly supplied with water at 15°C can dehumidify the ambience air without changing the

temperature. This is possible thanks to the presence of two heat exchangers which pre-cool the entering air and post-cool it after

the dehumidifying process.

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

also furnished of an ambience thermo-hygrostat and a braze welded plates condenser, which allow the unit to supply fresh air if the

ambience temperature goes over the set point set on the dehumidifier. The low air speed will not create annoying air currents,

typical of traditional air conditioning systems, granting the maximum comfort.

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.

2.1 STRUCTURE

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

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

Panels are covered with synthetic open-cells polyurethane material, in order to grant the maximum phono-absorbent. The used

material is classified in 1st class, according to regulations UL 94.

The unit is completely closed and the access is possible only from the front part 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.
