CONNECTIONS
The water, condensate discharge and electrical circuit ducts must be provided for.
WATER CONNECTIONS
- Make the water connections. To help
the bleeding of air from the coil, you
are advised to connect the water
outlet pipe to the fitting at the top;
any inversion will not jeopardise the
proper functioning of the unit.
The position and diameter of the
CONDENSATE DISCHARGE CONNECTION
During cooling operation the indoor
unit removes humidity from the air. The
condensate water must be eliminated
by co n n e c t i n g t h e a p p ro p r i ate
discharge coupling to the piping of the
condensate discharge system.

ELECTRICAL WIRINGS
WARNING: check that the power
supply is disconnected before
carrying out any procedures on the
unit.
In the specific case of electrical
wirings, the following must be
checked:
- Measurement of the electrical system
insulation strength
- Continuity of the protection wires
- The electrical wirings must be
made in compliance with the wiring
diagrams
The unit must be connected directly
to an electrical outlet or to an
independent circuit.
OMNIA fan coils are powered with a
current of 230V ~ 50Hz with an earth
connection, but the line voltage must
water connections are shown in the
dimensions.
You are advised to adequately
insulate water lines, or fit the auxiliary
condensate drain tray (available as an
accessory), to prevent dripping during
the cooling function.

knock out the diaphragm of the tray
on the water connections side.
Seal the unused drainage hole.
The condensate drain network must
be properly scaled and the piping
situated in such a way as to keep an
adequate slope along the route (min.
1%). If condensate is discharged into
remain within the tolerance value of
±10% compared with the nominal
value.
The electrical power cable must be of the
H07 V-K or N07 V-K type with 450/750V
insulation if inside a tube or raceway.
Use cables with double H5vv-F type
insulation for visible cable installation.
All the cables must be piped or ducted
until they are inside the fan coil. The
cables leaving the pipe or raceway
must be positioned in such a way
that there are not traction or twisting
stresses and they are anyway protected
from outside agents.
Stranded cables can only be used with
crimping terminals. Check the wire
strands are well inserted.

to use those on the machine as your
reference.
For all the connections, follow the wiring
diagrams supplied with the device and
shown in this documentation.
In installations with a 3-way valve, the
minimum water temperature sensor
must be relocated from its standard
mounting in the coil assembly to the
delivery hose upstream of the valve.
- Connect the power cables.
- Connect the earth cable.
- Connect the electric cables of the valve
accessory (if installed).
- Check all the connections and relative
cables are well fixed.
