Description
The air conditioning unit "2.0" is the new solution that
represents a significant step towards reducing the
aesthetic impact of air conditioners. With a depth of just
16 centimetres, "2.0" is the most compact and least bulky
of the category. Its aesthetic impact is therefore minimal,
both inside and out.
Optimised Capacities
The conditioning capacities of "2.0" have been optimised
so as to obtain the right temperature for the best level of
comfort and, therefore, less consumption and less noise.
Thanks to the careful choice of sound insulation materials,
the noise is similar to that of a standard wall split unit and
consumption is drastically contained thanks to the new
direct current fan.
BLDC inverter technology
We have perfected the inverter technology to offer the
best in terms of acoustic comfort (noise) and performance:
reduction of consumptions, maintenance of the best
temperature level and humidity level in the room.
Thanks to the use of the cutting edge BLDC (brushless
direct current) inverter regulation, vibrations have been
completely eliminated and acoustic emissions have been
lowered to exceptional levels.
Both ventilation motors are BLDC to reduce consumption
still further and make flow adjustment more precise.
The energy consumption is extremely low thanks to the
absorption values which, in the case of partial load, fall to
less than 300 W. At the nominal cooling power "2.0", in
the DC Inverter versions, it has a 3.9 EER, in the vanguard
in the sector of fixed-unit monobloc air conditioners.
Easy to install
“2.0" can be installed on any perimeter wall either low or
high. Everything needed for installation (template, support
bracket, hole pipes and external grids), excluding the drill
and drill bit, is included in the box.
Remote control and on-board touch-screen display
In addition to the remote control, the touch-screen
display on the unit enables the setting of any function.
There's even a "lock" mode to avoid any improper use.
With a simple action on the touch screen display, the
"heating" function can be deactivated: the appliance will
then operate in "cooling" only, without the need for the
condensate discharge pipe. The orientation of the air
flaps, upwards or downwards, can also be set by simply
pressing a key.
The packing is made of suitable material and carried out
by expert personnel. All units are checked and tested and
are delivered complete and in perfect conditions, however
please perform the following instructions to check the
quality of shipping services:
- upon receipt, check if the box is damaged. If that is
the case, accept the goods with reservations and
keep photographic evidence of any damage found
- unpack and check the contents against the packing
list.
- check that none of the parts have been damaged
during shipment. In case of damage, report it to
the shipping company within 3 days of receipt by
registered letter with return receipt and attaching
photographic documentation. A copy should also be
sent by fax to the MANUFACTURER. No notice of
damage incurred will be accepted after 3 days from
delivery.
Keep the packing at least for the duration of the
warranty period, in case you need to ship the air-
conditioner to the service centre for repair. Dispose
of the packing materials in compliance with current

INSTALLATION
Before installing the conditioner, it is essential to calculate
the summer thermal loads (and winter ones for the
models with a heat pump) of the room. The more exact
the calculation, the better the product will work. Please
refer to current regulations to carry out calculations. For
large-scale installations, please call a specialised heat
engineer firm. Therefore, try to reduce higher heat loads
by following instructions below:
- Cover large windows exposed to sunlight with curtains
or with external maskings (blinds, porches, reflecting
films, etc.).
- The room must remain closed for as long as possible.
- Avoid turning on halogen lamps or other high energy
consumption appliances such as small ovens, steam
irons, hot plates etc.).
For the best performance of the appliance and to avoid
malfunctions or dangerous situations, the location of the
unit must meet the following requisites:
- Respect the minimum distances indicated in the
diagram.
- The wall on which you intend to anchor the unit must
be robust and able to support its weight.
- Leave enough space around the unit to perform
maintenance operations.
- Nothing must obstruct the air flow both in the top
suction part (curtains, plants, furniture) and in the lower
outlet part, as it could cause vibrations which might
prevent the appliance from working correctly
The appliance is stated as having an IPX0 protection
rating, therefore it is not suitable for outdoor installation.
Check that there are no structures or systems (beams,
pillars, hydraulic pipes, electrical cables etc.) in the part
that must be drilled.
Never force the air flap open;
The appliance must not be installed directly above
another electrical appliance (TV, radio, fridge, etc.) or
above a source of heat.

INSTALLATION
To install the unit on a wall, drill 6 holes to attach the fixing
plate to the wall as indicated on the drilling template. The
appliance weighs more on the right, so make sure to
secure it properly on this side. The holes must have an 8
mm diameter to accommodate the 6 supplied plugs.
A thorough examination of the characteristics and
consistency of the wall must always be carried out to
determine the number of fixing points to be made and
to choose specific plugs in particular conditions. In the
case of installation on a plasterboard or on walls with low
density, place a bracket, if necessary on the outside, that
can support the appliance safely.
The manufacturer cannot be held responsible for
any underestimation of the structural consistency
of the anchoring carried out by the installer. We,
therefore, encourage you to pay the utmost attention
to this operation as, if performed badly, it could cause
serious damage to people and objects.
Drill a hole in the position indicated on the template for
those heat-pump appliances without a condensation
drain built in the wall to allow for draining of
condensation.
A hole is also indicated on the template to secure the
appliance on the wall with an anti-lifting bracket, which
is already on the appliance.

INSTALLATION
For heat pump appliances, a condensation drain pipe
(internal Ø16 mm, not supplied) must connect the unit to
the pipe on the rear of the appliance.
A solenoid valve will start the flow of the condensation
from the internal collection tray when the maximum level
has been reached. For cooling only appliances, this pipe
must be connected if the appliance is intended for use
with low external temperatures (below 23°C). Drainage
occurs by gravity. For this reason, it is essential for the
discharge pipe to have at least a 3% minimum slope in
every point. The pipe to be used can be rigid or flexible
with a minimum inner diameter of 16 mm. If the line flows
into a sewer system, it is necessary to add a siphon before
placing the pipe into the main drain. This siphon must be
placed at least 300 mm under the mouth of the appliance.
If the line flows into a container (e.g. a tank), do not
close the container hermetically and avoid immersing
the draining pipe into the water.
The hole for the condensation pipe must always slope
towards the outside.
The exact position in which to place the pipe mouth is
indicated on the template.
Check that the expelled water does not cause any
damage or problems to people or objects. During
winter, this water may create sheets of ice outside.
When connecting the condensation drain, be careful
not to squeeze the rubber duct.
It is possible to empty the collection tray using the
safety drain at the base of the appliance if necessary.

Bracket
Bracket anchoring points
Anti-lifting bracket
After checking that the bracket is anchored to the wall and
that all necessary electrical connections and condensation
drain preparations have been made, you can mount the
conditioner. Lift it by the sides of the bottom base until
the bracket fits on all of the right spots on the appliance.
In order to ease the operation, slightly tilt the appliance
towards you.
Direct electrical connections (disconnecting the power
supply cable) and the anchoring of the condensation drain
must be carried out after having spaced the appliance
from the wall using a wooden wedge or any other similar
object.
Once the work is done, check that there are no openings
on the back of the appliance, especially where the air
ducts are connected. To improve installation safety, the
machine can be secured to the wall with a dedicated anti-
lifting bracket
which is located on the rear part of the machine. The
drilling position is indicated on the installation template.
Mounting the appliance on the bracket
The unit to work requires water connection to an open or
closed water circuit.
The choice and installation of the components is
entrusted, by competence, to the installer who will
operate according to the rules of good technique and
current legislation. Before connecting the piping make
sure that these do not contain stones, sand, rust, slag
or in any case foreign bodies that could damage the
system.
It is advisable to create a by-pass in the system in order to
flush the exchanger without having to disconnect the
appliance. The connecting pipes must be supported
so as not to burden the appliance with their weight.
The hydraulic connections must be completed by
installing:
- air vent valves at the highest points of the piping;
- flexible flexible joints;
- shut-off valves.
The hydraulic connections are located in the lower part on
the left and must be arranged in such a way that they are
hidden by the air conditioner casing.
The minimum nominal diameter of the connecting pipes
must be 1/2 ".
To allow the maintenance or repair operations it is essential
that each hydraulic connection is equipped with the
relative manual closing valves.
The water connection pipes must be suitably insulated by
virtue of the supply temperature.
To avoid air pockets inside the circuit we strongly
recommend to put automatic or manual venting devices
at all points (higher pipes, siphons, etc.) where the air can
accumulate.
If the mains pressure is higher than 3 bar, install a pressure
reducer on the load.
Install suitable filters on the water inlet pipes of the
appliance according to the quality of the supply water.
At the end of the installation it is necessary that the
installer verify the good thermal insulation of every pipe
and fitting present in the hydraulic compartment.
In critical cases (hot and humid indoor air and low
water temperature) it is possible to have water leaks
from the base due to condensation on the connecting
pipes used by the installer.

Hydraulic and chemical characteristics of water
During the initial start-up phase, the specialized technician
must identify the reference values of the system water with
the appropriate test kits.
The internal water supply circuit has (as option) a two-way
modulating valve, driven directly from the interface by the
machine controller, which monitors the temperature of the
water leaving the heat exchanger by regulating the flow of
water to the heat exchanger for the maintaining 10 C ° n
heating and 35 C ° tags in cooling, in order to minimize
consumption and maximize returns.
The KVS of the valve used is:
Kv (m³ / h with Δp = 100kPa = 1bar) = 1.2
The general expression (valid for water or technically
similar fluids) for the calculation of load losses, knowing
the value of the flow rate, is as follows:
If the total hardness is higher than 20 ° F, or some reference
values of the make-up water do not fall within the indicated
limits, contact our pre-sales service to determine the
treatments to be implemented.
Well or ground water not coming from the aqueduct must
always be analyzed carefully and in case it is conditioned
by suitable treatment systems. In case of installation of a
water softener in addition to following the manufacturer's
instructions, adjust the hardness of the outlet water not
below 5 ° F (also performing the pH and salinity tests) and
check the concentration of chlorides in output after resin
regeneration.

MAINTENANCE
Objects or structural obstacles (furniture, curtains,
plants, leaves, blinds, etc.) must not obstruct the normal
air flow both from the internal and from the external grids.
Do not lean against, or worse sit on, the body of the
conditioner, this would damage the appliance.
Do not move the horizontal air outlet flap manually. Always
use the remote control to perform such operation.
In the event of water leaks, turn off the appliance and
disconnect the electric power supply. Call the nearest
service centre.
The appliance must not be installed in rooms where
explosive gases develop or where there are humidity
and temperature conditions that exceed the maximum
levels reported on the installation manual.
Clean the air filter regularly as described in the specific
paragraph.
Before leaving the site, the packaging should be gathered
up and all traces of dirt that have deposited on the unit
during assembly should be eliminated with a damp cloth.
These operations, which are not strictly necessary, in any
case allow for a more professional appearance of the
installation in the eyes of the user.
To avoid unnecessary calls by the user, before leaving the
site it is also a good idea to:
- outline the contents of the manual,
- show them how to clean the filter,
- explain when and how they should contact Customer
Service.

Fault Possible causes Solution
The appliance
doesn't switch
on
No power supply
Check there is power supply (by turning a light on, for example).
Check that the thermal-magnetic circuit breaker used exclusively
to protect the appliance has not been tripped (if it has, reset it). If
the problem repeats immediately, please call the Service Centre
and avoid trying to make the appliance work.
Remote control batteries have run out Check that the appliance can be turned on using the touch-
screen display and substitute the batteries.
The appliance
does not
cool/heat
adequately.
The temperature set is too high or too
low.
Check and, if necessary, adjust
the temperature setting on the remote control
The air filter is clogged Check the air filter and clean it if necessary
Check that there are no other obstacles
to the air flow both inside and outside. Remove anything that might block the air flow.
The heating and cooling load has
increased (for example, a door or
a window has been left open or an
appliance has been installed in the
room which generates a lot of heat).
Try to reduce the heating and cooling load of the room following
instructions below:
Cover large windows exposed to sunlight with curtains or with
external maskings (blinds, porches, reflecting films, etc.);
The air conditioned room must remain closed for as long as
possible;
Avoid turning on halogen lamps or other high energy consumption
appliances such as small ovens, steam irons, hot plates etc.).

OF Maximum level float
intervention
During cooling and dehumidification, electronics keeps the water distribution
system active with the battery - together with the fan - to disperse excess water
in the container. During heating, condensation should drain freely through the
specific pipe. In the event of an alarm, check that the condensation pipe is not
bent or obstructed, thus preventing the water from flowing out.
