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

Power supply

230÷240V/50Hz –240V/60Hz (1)

Inlet water temperature

3 ÷ 90°C

Maximum temperature air outlet (2)

50°C

Temperature of air inlet

10÷ 50°C

(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

Minimal counter pressure (motor range)

40 Pa

0 Pa

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:

Maximum air flow

MODEL

31-38

41-81

CAPACITY

1250 mc/h

2300 mc/h

4500 mc/h

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.
