OMNIA UL S FANCOIL
The OMNIA UL S fancoil combines advanced technologi-
cal and operational characteristics that make it the ideal unit
for air conditioning any room.
Treated air is immediately delivered to the entire room;
the OMNIA UL S produces warm air when fitted to a hea-
ting system with boiler or heat pump, but can also be used
during the summer season as an air-conditioning unit (if the
main system is also equipped with a water chiller).
The filter is easy to remove and is made of materials that
can be regenerated. It can be cleaned by washing. When
the fancoil is switched off the fins close, thereby preventing
dust and foreign matter from entering the unit.
The removable drip tray and fan volute ensure thorough
cleaning of the unit (by personnel with the necessary tech-
nical skills), essential for installations in venues subject to
crowding or in those with special hygiene requirements.
The new centrifugal fan assembly is so quiet that during
standard operation it's virtually impossible to hear when the
OMNIA UL S starts up.
The OMNIA UL S fancoil was designed for ceiling instal-
lations and in places where remote control is necessary, for
this reason it does not have a control panel and must be
combined with an optional control panel with thermostat or
commutator.
The use of electronic control panels eliminates the
annoying noises typical of mechanical thermostats.
It is easy to install and the water connections can be
reversed during installation.
Full compliance with safety regulations.
Routine maintenance is limited to periodic cleaning of the
air filter.
USE (OMNIA UL S)
CONTROLS:
Ventilation can only take place with the fins open.
These must be opened manually.
When the fins are closed the ventilation unit switches off.
Consult the manual supplied with the remote control acces-
sory.
CHARACTERISTICS OF OPERATION
OMNIA UL S fancoils are supplied with on-board controls,
and must be coupled with a compatible control panel
Ventilation
There are three ventilation speeds.
Ventilation is permitted with the fins open only.
PACKAGING
The fancoils are delivered in standard packing comprising
protective shells and cardboard.
INSTALLATION
IMPORTANT: check that the power supply is disconnected
before performing operations on the unit.
CAUTION: wiring connections installation of the fancoil
and relevant accessories should be performed by a techni-
cian who has the necessary technical and professional
expertise to install, modify, extend and maintain plants and
who is able to check the plants for the purposes of safety
and correct operation.
Install the fancoil in a position that will facilitate routine (filter
cleaning) and special maintenance, and easy access to the air
breather valve on the side of the unit (connections side).
Note that certain operating conditions could lead to the for-
mation of condensate on the unit housing with subsequent
dripping, or faults to the water circuit or condensate draina-
ge could cause liquids to overflow. For these reasons, avoid
installing the unit on surfaces damageable by moisture.
Make sure that the unit is installed in a site where the
ambient temperature is inside the minimum and maximum
limits 0 - 45°C (<85% R.H.).
To install the unit, proceed as follows:
a) Remove the cover by unscrewing the screws in the head
piece under the doors.
b) In the case of wall mounting, ensure a minimum distance
of 80 mm from the floor. For free-standing installation on
feet, refer to the instructions provided with the unit.
c) Use expansion plugs (not supplied) when mounting the
unit on the wall.
d) d) For ceiling installations, it is recommended that you use
the two brackets supplied.
e) Make water connections. To make the air vent from the
coil easier, you are recommended to connect the outlet
water pipe with the connection positioned on the top, the
possible inversion will not affect the proper unit operation.
The position and diameter of water connectors are given
in the dimensional data.
Insulation of water lines is recommended. Install the con-
densate water collection tray (optional accessory) to pre-
vent dripping during cooling operation.
N.B.: Use a tool to break the push-out in the drip tray
(water connection side) before connecting the condensa-
te drainage.
Size and arrange the condensate drain system in such a
way as to ensure a gradient of at least 1%. If drainage is
emptied into the sewerage system, fit a siphon to prevent
the return of unpleasant odours into the room.
Test the seal of water and condensate drainage connec-
tions.
f) Fit accessories (as applicable).
g) Make all wiring connections as shown in wiring diagrams
and the section "ELECTRICAL CONNECTIONS". Connect
the control panel to the connector on the inside of the
fancoil, then earth the unit.
h) Re-install the casing.
i) Check that the fancoil operates correctly.
ELECTRICAL CONNECTIONS
WARNING: always check that the electricity supply to the
unit has been disconnected before carrying out any opera-
tions.
In the specific case of electrical connections, the following
must be checked:
- Measurement of the isolation resistance on the electrical
system.
- Testing of the continuity of protection conductors.
Electric circuits are connected to mains voltage of 230V;
make sure that all components correspond to this voltage.
