DESCRIPTION
System types
The fancoils are designed for 2 and 4 pipe systems with fixed or variable
flow rate, in versions:
- 3 Rows and 4 Rows;
- 3 Rows with 2-row hot water coil for heating-only.
- 4 Rows with 1-row hot water coil for heating-only.
Ventilation
Ventilation is controlled via a control panel (accessory).
The 5-speed fan motor can connect the control panel to 3 speeds that
produce the optimum useful static pressure for the system.
HEAT EXCHANGE COIL
Main coil with 3 and 4 rows Heating-only coil with 1 or 2 rows Battery
with low pressure drops, in copper piping and corrugated aluminium
fins, blocked via mechanical expansion of the tubes. The collectors are
fitted with female hydraulic connections and air vents in the upper
part of the coil.
FILTERING SECTION
Air intake filter, easily removable for periodic cleaning Built with renew-
able materials and can be cleaned with a vacuum cleaner.
Filtration class G3. Behaviour to flames M1 NF F 16-101.
ELECTRIC FAN UNIT
Double suction centrifugal fans with fans designed for low noise emis-
sion.
The fans are directly coupled with the shaft of the electric motor.
The 5-speed fan motor allows you to choose the 3 preferred speeds by
changing the settings on the electrical box on the motor.
The electric motor is cushioned with elastic supports.
The leakage current to earth of several devices placed under the same circuit breaker is summed, so attention should be
paid to the calibration of the circuit breaker and possibly consider the division of the installation into several circuits each
of which protected by its own circuit breaker.
INSTALLATION OF THE AIR OUTLET FLANGE VED 030 040 130 140 230 240 330 340 (SEE PAGE 27 FIGURE 1)
When using the flange, supplied with the machine, do the follow-
ing:
Take out the bag containing the components supplied with the
fan compartment by removing the air filter in advance, as indi-
cated in the instructions
Fit first the two side bars using four screws in the bag supplied
screwing them into the 4 holes in the sides of the unit
UNIT INSTALLATION (SEE PAGE 27 FIGURE 2)
To install the unit, proceed as follows:
- For wall mounting, maintain a minimum distance of 160mm
from the floor;
- For ducted installation, provide the fitting of the channels to the
unit, see the drawing with the dimensional data. The outlet is
already provided with coupling flange.
- Use expansion bolts (not supplied) for wall or ceiling installa-
tion, finally make sure that the unit is installed horizontally.
- For installation suspended from the ceiling, use four M8 thread-
ed rods to support the frame. Secure the unit to the 4 threaded
rods using 8 nuts of which 4 self-locking nuts. Use the nuts
to adjust the height of the unit; finally, check that the unit is
installed in a horizontal position
HYDRAULIC CONNECTIONS (SEE PAGE 27 FIGURE 3)
- Make the hydraulic connections.
WARNING: Always use a wrench and counter-wrench to fix the
pipes.
Refer to the size data for the position, type and diameter of the
hydraulic connections.
You are advised to adequately insulate water lines and/or fit the
auxiliary condensate drain tray (available as an accessory), to

Structure
Made of galvanised sheet iron of a suitable thickness. Internal insulation
in Class 1.
The installation slots are positioned at the rear.
The inlets and outlets are designed to connect the fancoil to all types of
air ducting.
The outlet includes the coupling flange.
CONDENSATE DISCHARGE
Every device is equipped with a condensate collection tray for both ver-
tical and horizontal installation. The fan coil drip tray has got 2 conden-
sate discharges (on the right and left hand side).
It is recommended to use the condensate discharge on the water
connections.
HYDRAULIC CONNECTIONS
The connections, located on the left hand side, are female. The coil can
be rotated onsite to reverse the fittings onto the right side.
Control panel
There are several control panels available to choose the most suitable for
the system.
The full potential of the VED units can be exploited by combining the
control panels, thermostats and other accessories of the VMF series.
The thermostats of the VMF series allow to:
- Control a single unit and the accessories.
- Control a network of 6 units, including a master with thermostat and
control panel plus 5 slave units equipped with thermostat, which oper-
ate independently based on the ambient conditions.
- Control of the VED unit in a complex network of up to 64 zones
with 6 fancoils (up to 384 fancoils with a single VMF-E5
control board).
Paste the / The adhesive strips in the lower part of front and rear
cross-members,
Lay the two crosspieces to the car and through the remaining 4
screws to fix the cross to those previously placed
Note in the event of non-use of the flange, however, extract the
bag of accessories out of the car.
- WARNING: The fan coil must be installed in a horizontal posi-
tion, otherwise the correct discharge of condensate can not be
guaranteed.
- Make the hydraulic connections as described in the relative
chapter.
- Make the condensate discharge connection as described in the
relative chapter. The fan coils that work in heat mode only do
not require condensate discharge.
- Make the electrical wirings as shown in the relative chapter and
in the wiring diagrams.
- Install and connect any accessories.
- Start up the fan coil and check all the components and func-
tions are operating correctly.
prevent dripping during the cooling function.
After installing, check the seal on the connections.
Warning: Bleed the hydraulic system. The relief valves are
positioned at the top of the coil near the hydraulic fittings.
Warning: To discharge the unit, use the exhaust valves located in
the lower part of the coil near the hydraulic fittings.
