OMNIA UL PPC FAN COIL
The OMNIA UL PPC fancoil concentrates high technolo-
gical and outstanding functional features that make it the
ideal climate control resource in horizontal and vertical
installation, channelled and in Ventilcassaform style.
The supply of climate controlled air is immediate and
distributed throughout the room; OMNIA UL generates heat
if inserted in a heating system with boiler or heat pump but
it can also be used in summer as an air conditioner if the
heating plant has an air chiller.
The air filter is precharged electrostatically, featuring high
efficiency and low pressure drops it has degree of fire resi-
stance that puts it in Class 2 (UL900).
The quality of the air treated is guaranteed by a special
electrostatically precharged filter that absorbs and traps
suspended dust,when the fancoil is off the closed finning
prevents dust and foreign bodies getting inside and by the
new"PLASMACLUSTER" purifier that breaks down the water
and oxygen molecules , normally present in the air in the
room ("humidity" and "oxygen"), in positive and negative
ions. These ions liberated into the air will stick to the mole-
cules of the polluting substances and by being recombined
(once activated) decomposes them into non-toxic sub-pro-
ducts (water, oxygen and carbon dioxide etc..).
The "PLASMACLUSTER" air purifier is activated at the same
time as the ventilation when both hot and cold.
The possibility of removing the basin and the inspectionable
fan volutes (only by suitably trained and qualified person-
nel) it allows thorough cleaning to be carried out even in
the interior parts, an essential condition when installed in
very crowded areas or places requiring high standards of
hygiene.
The quietness of the new centrifugal fan assembly is such
that at normal speeds of use you cannot hear when OMNIA
UL PPC cuts in.
The use of the electronic control panels avoid the
annoying noise typical of mechanical thermostats.
Installation is made easier because the hydraulic attach-
ments can be reversed on installation.
Full respect for accident prevention regulations.
Servicing is reduced to periodic air filter cleaning or its
replacement.
USE (OMNIA UL PPC)
COMMANDS:
Consult the manual provided with the PXA Econtrol panel.

FUNCTIONING CHARACTERISTICS

THE OMNIA UL PPC fancoils are supplied without control
panel on the equipment, to be linked with an external con-
trol panel available as an accessory (PXA E).
Ventilation
Ventilation is at three speeds.
PACKAGING
The fancoils are sent with standard packaging consisting of
protective shells and boxes.
INSTALLATION OF THE UNIT
WARNING: before carrying out any work, make sure the
electrical power is unplugged.
CAUTION: electrical connections, the installation of the
fan coils and their accessories must only be carried out by
people with the proper technical and professional qualifi-
cations for the installation, conversion, expansion and
maintenance of the machinery and able to check that it is
working properly and safe.
The fancoils must be installed in such a position as to allow
easy servicing (cleaning of the filter) and extraordinary main-
tenance as well as access to the air breather and exhaust val-
ves on the side of the frame (attachments side); you are advi-
sed not to install the fancoil above objects that suffer from
damp or wet because in some conditions condensation may
form on the external frame of the equipment with the possi-
bility of dripping or failures may occur in the hydraulic
system and condensate drainage with the consequent spil-
ling of liquid.
The fancoils used for the cooling must be attached to a con-
densate draining system.
The assembly site must be chosen in such a way that the
maximum and minimum ambient temperature limits are
respected 0÷45°C (<85% U.R.).
To install the unit proceed as follows
The filter is fitted in a sealed package to prevent the loss of
its electrostatic charge, open the box and fit the filter only
when the fancoil is to be used.
With Ventilcassaforma applications the UL-P fan coil must
be installed after the Ventilcassaforma has been built into
the wall. Electrical and plumbing connections must be
made after consulting the CHU accessory manual.
a) Keep a minimum intake distance from the wall or from the
floor of 80 mm.
b) For fixing to the wall use screw anchors (not supplied).
c) When fixing to the ceiling, you are advised to use the two
brackets supplied.
d) Make the plumbing connections, to help the bleeding of
air from the coil, you are advised to connect the water
exit pipe to the fitting at the top, if inverted it will not
jeopardise the proper functioning of the unit.
The position and diameter of the plumbing connections
are shown in the size information.
You are advised to insulate the water piping properly or to
install the special auxiliary condensate collection basin,
available as an accessory, to avoid dripping while working
in cold mode.
N.B.: Before connecting the condensate drainage pipe, push
in the diaphragm off the basin (if present) on the plumbing
attachment side, seal the drainage not used with the cap
provided.
The condensate drain network must be properly scaled and
the piping situated in such a ways as to keep an adequate
slope along the route (min.1%). In the case of drainage into
the sewerage network, you are advised to make a syphon to
stop bad smells being returning into the room.
Carry out the plumbing connection and condensate draina-
ge tightness tests.
e) Apply any accessories.
f) Make the electrical connections as shown in the wiring
diagrams and in the "ELECTRICAL CONNECTION" sec-
tion by connecting the wires of the control panel on the
inside side of the fancoil and by grounding.
h) Make sure the air filter is positioned correctly.
g) Make sure the fancoil is working properly.
