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
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.

connections.
During cooling operation the indoor
unit removes humidity from the
air. The condensate water must
be eliminated by connecting the
appropriate discharge coupling to the
piping of the condensate discharge
system.
N . B . : B e f o r e c o n n e c t i n g t h e
condensate discharge, use a tool to
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
the sewage system, install a siphon
to prevent the return of unpleasant
odours into the room.
Test the condensate discharge
seal.
The water, condensate discharge and electrical circuit ducts must be provided for.

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 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.
The wiring diagrams are subject to
continuous updates, so it is essential
to use those on the machine as your
reference.
For all the connections, follow
t h e w i r i n g d i a g ra m s s u p p l i e d
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.
