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.

3.1 PROJECT CRITERIA
All copper pipes are realized under our specifications in order to control all the construction process and to increase our products
quality standards. Each pipe is tested through the FEM code on the more stressed point with a 90° fold and under the maximum
allowed pressure according to the safety coefficient.
Compressors
Reciprocating compressors are mounted on the units. Engines are thermally protected through an internal protection
which controls the temperature of winding and disables the power supply in case of maintenance.
Refrigerant components
oFilter drier with molecular sieve
oThrottling valve
oSchrader valve for control / maintenance
Thermal exchange coils
oCopper pipes and aluminum fins
Condensate tray (below coils)
oINOX steel
4ELECTRICAL CONNECTIONS
4.1 ELECTRICAL EQUIPMENTS
The electrical panel is realized and wired according to the Regulations mentioned in the Declaration of Conformity.
The control circuit is protected by a dedicated fuse.
All the remote commands are realized with low tension, supplied by an insulation transformer.
To stop the group do not remove tension through the protection at the base of the unit: this organ
should be used to section the whole unit for maintenance. To turn off, use the user terminal.

5USER TERMINAL
The unit leave the factory with status “OFF” (to turn it on, keep pressed for more than 1 second the [STAND-BY] key, and it will turn
to “ON”), ready to function.
The control manages all the functions and the devices of the unit, by operating under the call from the external humidistat.
Remember that the compressor has a delay when starting and re-starting of 5 minutes, in order to avoid mechanical damages to the
internal components.
Every problem / error is displayed, according to the DIAGNOSTICS AND ALARMS chapter.
By default, the ventilation is combined with the compressor starting.
Some of these regulations can be modify according to the PARAMETERS TABLE below.
5.1 DISPLAY AND KEYS
UP ( ▲)
Increases the values / Browses parameters.
Turns off the sound alarm, if present.
DOWN ( ▼)
Decreases the values / Browses parameters.
STAND-BY

Units “I” need to be supplied with cold water in order to function properly, otherwise units cannot
function and they will block.
Units “A” can function without cold water, in this case dehumidification capacity decrease and air is supplied at temperature higher
than the inlet.
1. Dehumidification capacity is declared at nominal conditions 26°C, 65% RH with water at 15°C.
In other conditions dehumidification capacity varies.
2. Sound pressure level is declared in free field at 1 m from the unit ducted.
