1-INTRODUCTION
The SOFFIO Series is designed for the air-conditioning systems in residential and commercial application,
for indoor installations, not to expose to low or high extreme temperatures, dust-free and non-explosive
environment. The manufacturer is not responsible in case of incorrect use.
The units are designed to be ducted. To install without ducts can produce malfunctioning or damage of the
unit.
2-OPERATING LIMITS

(1) +/-6% of margin on the voltage. All the technical data given in this manual refer to 230V / 50Hz.
(2) In case of water with outlet temperature higher than 50°C, please verify the temperature of the air outlet
with selection software TESI10

The working with low external counter pressure, even if inside the motor range, may cause the separation of
drops from the coil during summer operation (to be evaluated also according to the degree of humidity). To
avoid this possibility, you should work with at least 40Pa of pressure and not more of the following air flow:

CAPACITY

We suggest to let the unit work to the extremes of these operating limits only for short periods, because the
operation for a long period of time may reduce the normal duration of the components.

3- KEY TO READING CODES
The standard version is horizontal, single panel, 3 row coils, three-speed AC motor, right hydraulic
connections. All other versions are optional.

4-TECHNICAL SPECS
STRUCTURE: made of galvanized steel, thickness 1.00 ÷ 1, 50 mm. The sturdy structure prevents vibrations
and includes the mounting brackets to the ceiling. On request, it can be painted.
ACCESSIBILITY: the filter can be removed both from the bottom and the sides, without the aid of tools (if
some accessories are installed on the suction side, please refer to the specific chapter of this manual for
more information). Accessibility to internal components is guaranteed by removing the bottom panel. The
plate of the fan deck can be removed without disconnecting the ducts and the operation can take place from
below, without the need to intervene on the sides or front of the unit.
FILTER: class G3 (EN779), thickness 15 mm, synthetic fiber. Other types upon request.
FAN DECK (AC motors): the fans are forward curved blades, double suction centrifugal fan, directly coupled
to the motor. The cochlea is made of galvanized steel, the fan in aluminum. The motor and the fans are
balanced on the plate of the fan deck after their assembly. The motor is mounted on rubber anti-vibration
supports , protection level IP20, 3 speeds.
FAN DECK (EC motors): the fans have forward curved blades, double suction centrifugal fan, directly
coupled to the motor. The cochlea is made of galvanized steel, the fan in aluminum (size 21-31) or in plastic
(size 38-41-81). The motor and the fans are balanced on the plate of the fan deck after their assembly. The
motor is mounted on rubber anti-vibration supports, protection level IP20, control signal 0-10V.
COIL: made with copper tube 3/8" diameter and corrugated aluminum fins with high efficiency, with manual
air purge valve at the top of the collector. The standard connections are right (looking in front of the air flow).
Left on request. Nominal pressure PN10.
The direct expansion coils (optional) are made with copper tube 5/16 "diameter and they are suitable to work
with refrigerant R410A (up to 45bar). Other refrigerants on request.
CONDENSATION DRAIN PAN: made of galvanized steel and painted to prevent rust. The drainage pipe and
the edges are welded to avoid losses even after a long time. The drain pan is externally insulated with
thermal insulation and it is mounted with slope towards the drain pipe to avoid water stagnations.
INSULATION: made of polyurethane with thickness 10 mm, HF1 class according to the rule UL94 (flame
retardant and not dripping). The thermo-acoustic insulation is protected against moisture and dust thanks to
a surface film.
ELECTRICAL PANEL: made in galvanized steel or plastic, it is positioned on the opposite side to hydraulic
connections. On request it can be made with a watertight box in plastic and it can be placed on the same
side of the hydraulic connections.

The accessories of the group “D” need the accessory FP (if they are connected in outlet) or FRA+FP (if they
are connected in inlet) to be connected to the structure of the unit. Furthermore the accessories of the group
“D” can be connected in series among them.

10.1-Valves
We suggest to use motorized valves in order to avoid condensation on the surface of the unit when the fan
doesn’t work.
The valves are supplied in kit, not mounted, to avoid damages during transport and/or installation.
