1.3 Description (UIS)
The Vision 2.3 is the new solution by Powrmatic, a signifi-
cant step towards reducing the aesthetic impact of air
conditioners. Being only 16 centimetres deep, the Vision
2.3 is the thinnest and less bulky in this category, there-
fore both the internal and external aesthetic impact is kept
to a minimum.
Optimised Capacities
The conditioning capacity of the Vision 2.3 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 insula-
tion 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.
162 millimetre holes
An important choice, not only design-wise, but also
because of a considerable installation advantage: it is
easier to find drilling tools, with lower aesthetic impact.
Easy to install
The Vision 2.3 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, is included in the box.
Folding external grids
Remote control and touch screen display.
In addition to the remote control, the touch screen display
on the unit enables the setting of any function. There is
even a ‘lock’ mode to avoid any improper use. It is possi-
ble to deactivate the ‘heating’ mode by simply touching
the screen. the unit then works in ‘cool only’ mode,
without the need to use the condensation drain pipe. The
orientation of the air flap can also be adjusted by simply
pressing one key.

2.1Installation mode (I)
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 accu-
rate calculations, the better the product will work. Please
refer to current regulations to carry out calculations. For
big installations please call a study specialised in thermo-
dynamics. Try to reduce the thermal refrigeration load of
the room following these instructions:
Cover large windows exposed to sunlight with curtains or
with external masking (blinds, porches, reflecting films
etc.)
The room must remain closed for as long as possible.
Avoid using halogen lamps or other high energy
consumption appliances such as small ovens, steam
irons, cooking plates etc.
2.2 Choosing the position of the unit (I)
For a better 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
picture.
The wall on which you wish to anchor the unit
must be robust 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 form working
correctly.
The appliance must be installed against a wall
connecting with the outside.
Check that there are no structures or systems
(beams, pillars, hydraulic pipes, electrical cables
etc.) in the part of the wall that must be drilled.
Check that nothing is placed in front of the holes
thus obstructing the air flow (plants and leaves,
panels, shutters, grates, etc)
The unit should not be installed in a position
where the air flow aims directly at people nearby.
Do not force the air flap open.
The appliance must not be installed directly
above, or below another electrical appliance
(TV, radio, fridge, etc.) or above a source of
heat.

2.3 Assembling the unit (I)
The maximum length of the holes is of 1 m and
there must be no bends. Use the supplied grids
or grids with the same characteristics.
For the unit to work, two holes must be placed as indicat-
ed on the template.
The holes on the wall must be drilled using suitable equip-
ment that does not cause damage or excessive inconve-
nience to your client. The best tools to make big holes are
special drills (called “core drills”) with a high torque and
whose speed can be adjusted according to the diameter
of the hole and the material to be drilled. In order to avoid
excesses dust and debris in the room, “core drills” can be
combined with suction systems composed of a vacuum
connected and a suction cup which can be placed next to
the drill. In order to make the holes, proceed as follows.
Place the template provided against the wall,
respecting the minimum distances from the
ceiling, the floor, and the side walls, as indicated
on the template. The template can be held in
place using adhesive tape. A spirit level can be
used to ensure the unit is square.
Mark the centre of each hole with a small drill or
a punch before actual drilling commences.
Using the core drill, make two holes for the inlet
and outlet air.
The holes must be drilled slightly downward
towards the outside, to avoid water from entering
the building.
The majority of the removed material is expelled outwards
so please be careful that it does not hit people or objects.
In order to avoid breaking the outer plaster, be careful
while drilling the final part of the hole and ease the pres-
sure on the core drill.
Drill the 6 holes for the bracket as indicated on the
template.
The appliance weights more on the right side, so make
sure it is properly supported on this side. The holes must
have an 8mm diameter to accommodate the 6 supplied
plugs.
In any case, check the characteristics and the consisten-
cy of the wall to see whether specific plugs may be
needed.
The manufacturer cannot be held responsible for
any underestimates or the structural consistency
of the anchoring arrangement made by the
installer. We therefore encourage you to pay the
utmost attention to the operation, as if performed
badly it could cause serious injury or damage.
Drill a hole in the position indicated on the template for
those heat pump appliances without a condensation drain
built in the wall in order to enable the drainage of conden-
sation.

Vision 2.3 Air Condioner Range Issue 1.0 June 2014 Page 11
2.1 Fitting the unit
Condensation drain predisposition
For heat pump appliances, a condensation drain pipe
(Ø10mm, internal, not supplied) must be connected to the
pipe on the top part 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, said pipe
must be connected if the appliance is going to be used
with low external temperatures, (below 23oC). As it is a
gravity drain, it is essential for the line to have at least 3%
slope minimum at every point. A rigid or flexible pipe can
be used with a minimum internal diameter of 10mm. If the
line flows into a sewage system, it is necessary to be
trapped before connecting to the drain. Said trap must be
placed at least 300mm 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
lean 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 problem to people or objects.
During winter this condensation can freeze to
form ice on pathways.
When connecting the condensation drain, be
careful not to squeeze the rubber duct.
It is possible to empty the collecting tray using
the safety drain at the base of the appliance if
necessary.

2.4 Assembling air ducts
and external shutters (I)
Once the holes have been made, place the supplied
plastic sheet inside them.
Roll up the sheet and insert it in the hole, checking that
the joint is facing upwards.
Use a cutter to remove any excess pipe.
To place the external grids, proceed as follows:
Connect the chains to the ends of the springs.
Fold the external shutters.
Insert your arm in the hole to push the shutter to
the outside, whist holding the the chain with the
other hand to prevent the shutter from falling.
Open the shutter inside the hole.
Rotate the shutter to bring the flat into the verti-
cal “C” position and check that the closing mech-
anism works.
Pull the chains by tensioning the springs.
Insert the internal flange in the hole with the
internal hooks in the vertical position.
Fix the chains to the internal flange’s hooks
Use a bolt cutter to remove any excess chain.
Anchor the hook of the chain to wall “B”.
Use only the supplied grids or grids with the
same characteristics.
The grids must be positioned with the flaps verti-
cal.
The shutters are different. Check the opening of
the shutter to determine if they are the inlet or
outlet shutter, and fit accordingly.

2.5 Mounting the appliance on the bracket (I)
After checking that the bracket is anchored to the wall and
that all necessary electrical connections and condensa-
tion drain have been made, you can mount the condition-
er. 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 appli-
ance from the wall using wooden wedges 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.

Open CP contact
If the contact is not closed on the CP connections the
appliance will not start and the CP alarm appears on the
display.
Emergency condensation air dis-
charge
Should any anomaly occur in the condensation water
system, the maximum level float blocks the conditioner
and the OF code appears on the display.
During cooling and dehumidification, electronics switch
the compressor off and keeps the water distribution
system active with the battery - together with the fan - to
disperse excess water in the container. If the problem
persists, please contact the assistance service.
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 prevent-
ing the water from flowing out.
Operation after installing
Before leaving, collect the packaging and clean any dust
on the appliance with a damp cloth. These operations,
though not strictly essential, transmit a sense of profes-
sionalism to the user.
In order to avoid unnecessary calls from the user, it is
best, before leaving to :
Explain the contents of the Manual.
Explain how to clean the filter.
Clarify when and how to call the Assistance
Service.

getting burned.
Do not use abrasive sponges or abrasive or
corrosive detergents to avoid damaging the
varnished surfaces.
When necessary, clean the external surfaces with a soft
damp cloth.
Cleaning filter
The air conditioner you have bought has been designed
to keep maintenance operations to a minimum, which
only concern the following cleaning operations:
Clean the air filter after a period of continuous
use and in accordance with the concentration of
impurities in the air, or when you wish to start-up
the appliance after a period of inactivity.
The filter is placed on the top part of the appli-
ance.
To extract the filters:
Open the grid and remove it.
