CHAP. 2 INSTALLATION
CHAP. 2.1 INSTRUCTIONS FOR INSTALLATION
To obtain the best results and optimum performance, follow
the instructions for correct installation provided in this
manual. Failure to follow the instructions and apply the
rules indicated may cause malfunction of the appliance and
relieves the manufacturer of any form of guarantee and
liability for damages to persons, animals or property.
The electrical system must comply with the regulations
and rating data in the technical sheet, with good
grounding.
SELECTION OFPOSITION OFTHE UNIT
The position for installation of the inside unit, to obtain the best
performance and prevent breakdowns or hazards, must have the
following requisites:
-The bottom of the low level unit must be at least 300mm off the
floor whilst the high level unit must be at least 2 meters off the
floor and no more than 3 (fig. 1)
-The wall on which the inside unit is installed must be
sturdy and able to withstand its weight.
-There should be no obstacles to the free circulation of air on the
intake side andon the air outlet side especially, there should
be no obstacles closer than 2 m (this could cause turbulence that
would interfere withcorrect operation of the unit).
-It must be possible to leave room around the unit for any
maintenance operations that may be necessary.
The air conditioner must be installed on a wall that
communicates with the outside.
Caution: After determining the best place for installation
as described above, check to make sure that the wall can
be drilled in that point without interfering with other
structures or installations (beams, piers, pipes, wires,
etc.). Check again to make sure there are no obstacles
to air circulation through the holes to be drilled due to
plants and their leaves, slats or paneling, blinds,
gratings or grids too dense, etc.).
Before installing the air conditioner, it is essential to make an
accurate calculation of the heat load in summer (and cold
load in winter for models with heating pump) at the site of
installation.
The more accurate this calculation is made the better the air
conditioner will be able to do its job.
To make these calculations, refer directly to the regulations in
effect (UNI ref.Law 10/91) or tothe tables, both printed and
computerized, based on those regulations. For particularly
significant applications, we recommend contacting expert
heating engineers.

2.2.2
Dimensions and
features of site
where air
conditioner is
installed

As far as possible, in any case, it is important to try and reduce major
thermal loads by the following means: Large glass panes exposed to
sunlight should be provided with curtains on the inside or shades on
the outside (Venetian blinds, verandas, refracting films, etc.) The air-
conditioned room should be closed as much of the time as
possible.
Halogen spotlights or other electrical equipment with high power
consumption should not be used in the room (toasters, steam irons,
hot plates for cooking, etc.).
-It should not be installed in a position where the air flow can strike the
people underneath directly (fig. 2).
-It should not be directly over another appliance (television set,
radio, refrigerator, etc.), or over a source of heat (fig. 3).
-There should be no obstacles for reception of signals emitted by the
remote control (fig. 4).
CHAP. 2.3 INSTALLATION OF THE UNIT
2.3.1 This operation should be carried out using the proper tools
Drilling the wall to facilitate your work and prevent excess
damage or disturbance to your client. The best tools for drilling large
holes in walls are special drills called core borers with very high twisting
torque and adjustable rotation speed depending on the diameter of the
hole to be drilled.
To prevent the creation of large amounts of dust and rubble due to drilling,
the core borer can be fitted with a vacuum system applied by means of
suction cups to the drilling zone.
Compact Solutions would be able to assist you in locating these
devices.
To drill the holes, proceed as follows:
Fasten the drilling template to the wall leaving the necessary space
from the ceiling, floor and side walls as shown on the template. Use
adhesive tape to fasten it in place.
Use a small drill or punch to mark, with extreme care, the exact centre of
each of the holes to be drilled.
Usinga core boring head measuring at least 158mm to drill the two holes
for entry and exit of the air.
Note: The holes should have a slight outward inclination to
prevent any backflow of water from the pipes (see fig.1).
Most of the removed material is expelled outwards, therefore make
sure that it does not hit any person or object when it falls out.
In order to avoid as much as possible outer plaster breaking, it is
necessary to proceed carefully with the last part of hole execution,
decreasing pressure on core borers.
Fig 5

Next, drill the holes for anchoring the fastening brackets to the wall
using as a first option the 4 holes on the ends of the bracket as
shown on the drilling template (see fig. 6).
If the wall is not very solid, it is advisable to use some extra
anchor bolts.
As you can see, the bracket can be fastened in a number of
different ways and positions. The air conditioner is heavier
on the left-hand side, so it is best to make sure of a solid
anchorage on that side. The anchor bolts provided require holes
with a diameter of 10 mm. In any case, the wall should be
inspected carefully to determine the best possible anchorage and
type of bolts suitable for particular situations.
Warning: The manufacturer is not liable in case of
underestimation of the structural consistency of the
anchorage made at the time of installation. We
therefore recommend that you perform this operation with
the maximum care as, if not done properly, it can cause
serious damage to persons and property.
When installing models equipped with heating pump, if no
drainage well for condensate has been provided built into the
wall (see paragraph 2.3.2), it will be necessary, to allow for
drainage of the condensate, to drill a hole through the wall
measuring 16 mm in diameter in the position shown on the
template (see fig.6).

2.3.2 When the machine is heating, it produces condensate
Provision for that has to be eliminated through a specific drain line,
draining con-otherwise the machine will not work. Drainage occurs by
densate for gravity. For this reason, it is essential for the drain line to
machines with have a minimum inclination of at least 3% throughout its
heat pump. length. The pipe can be rigid or not, with a minimum
internal diameter of 16 mm. If the line drains into a sewer
system, it should be provided with a trap ahead of the main
outlet. The trap should be at least 300 mm lower than the inlet
opening on the air conditioner (fig. 7).
If the drainpipe drains into a vessel (tank or other container),
this container should not be sealed and the drainpipe should
not remain immersed in the water (see fig. 8).
The correct position for the pipe inlet on the machine is shown on
the template for drilling and positioning the machine (see
also fig. 6).
The air conditioner is equipped with a pipe with an external
diameter of 14 mm for drainage of condensate. Thispipe
protrudes from the machine for a length of about 400 mm.
The pipe should be fitted inside the one provided by you for a
distance of at least 200 mm, without any sharp bends that could
obstruct it.
When draining toward the outside, the pipe can be inserted
through the wall (always making sure to give it a suitable
inclination) (see fig. 5).
Caution: make sure, in this case, that the water expelled
outward does not damage or disturb persons or
property. During the winter this type of drainage may
cause sheets of ice to form.
2.3.3 After drilling the holes, the plastic pipes supplied with the
Installation of air air conditioner have to be fitted through them. The pipe
pipes and with insulation on the inside has to be fitted in the right
external hand hole with the insulated part toward the inside as
gratings indicated on the label applied to it. The length of the pipes
should be 55 mm less than that of the wall. To cut the pipe,
a normal handsaw can be used. After cutting the pipes, fit
the ends into the two internal anchoring flanges (fig. 10).
The tube diameter is 152mm and should fit comfortably into
the hole formed by the 158mm diameter core drill. When
introducing the tubes they may need to be forced slightly using, in
the most difficult cases a normal rubber hammer (fig. 10/1).
Having the hole internal diameter extremely similar to the
tube external diameter avoids dangerous slacks which may
generate humidity infiltrations or air noises. Should the insertion
prove to be too difficult, we suggest you drill using the core bit
inside the hole so as to widen the internal diameter slightly. If
there is excessive play and air gap around the tubes then we
recommend a sealant be used to ensure a tighter fit.
Next, fit the pipes into the holes in the wall and fasten the flanges
with 4 anchor bolts with diameter 6, taking care to keep the two
fastening holes in a horizontal position. Fig. 9
F
ig 10/11

To position the external grids, proceed as follows:
-Fit the small eyelet of the spring, with the long stem, on
the cap pin (on both components) (fig. 10/2).
-Fit the two caps (with spring), from the front part of the
external grid, on the two housings, pulling until a click is heard
(fig. 10/3) and attach the two chains to the large eyelet
of the spring.
-Using one hand, grip the two chains connected to the grid.
-Bend the external grids back, gripping these with your
free hand where the bend is and introducing your
fingers inside the single fins (fig. 10/4).
Introduce your arm into the pipe until the grid protrudes
completely outwards.
-Allow the grid to reopen, being careful to keep your
fingers inside the fins.
-Turn the grid until the fins are fully horizontal and tilted
towards the outside.
-Pull the chain, tensioning the spring, and fasten the ring
of the chain onto the pin of the inner washer (fig. 11).
-Using a pair of nippers, cut the excess chain links (fig.
12).
Warning: If the external grating is accessible, to
prevent the hazards resulting from its possible
removal (insertion of the hands into the pipes and
touching moving or powered parts) it is absolutely
essential to fasten it to the wall with 4 anchor bolts
with a diameter of 6 mm.
2.3.4 The air conditioner is equipped with a power supply cable
Power supply and plug.
Connection If it is installed near an outlet, you need only plug it in.
In this case, it is important to make sure the outlet to which
you are plugged in is effectively grounded and connected
to the mains by wiring of adequate size (minimum 1.5
sq.mm. cross section). To make an electrical connection
with the shielded cable (recommended for installations high on
the wall) proceed as follows:
Install a shunt box in the wall in the position shown on the
installation template (fig. 6), where you should provide a power
cable with a cross-section (two poles plus ground wire) of 2,5
sq.mm.
Warning: The external power line should be provided with
an overload circuit breaker with suitable capacity for the
rating of the machine.
Make all connections in compliance with the laws in effect.
Close the shunt box with its cover after drilling a hole in it for
passage of the cable.
Alternatively, you can use a cable in the wall in the position shown
on the template, for making the connection. In this case,
remove the casing (as described in paragraph 2.4.2) and
connect the cable to the power terminal board.
Caution: these operations should be performed with the
machine already positioned on the bracket. Read the
instructions carefully before completely the electric
connection.

2.3.5 After checking again that the fastening bracket is securely
Fitting the unit fastened to the wall, and that any necessary preparations
on bracket for electric connection and condensate drainage have been
made, you can fasten the air conditioner to its supporting bracket.
Lift it up holding the sides of the bottom (see fig. 13).
To facilitate the operation of fastening it to the bracket, tilt it slightly
toward you.
To make the electrical connection and fasten the drainpipe, place a
wedge between the air conditioner and the wall (see fig. 14).
After these operations have been carried out, the air conditioner
can be pushed firmly against the wall so that the bottom hook
catches.
When you have finished, inspect carefully to make sure there are
no fissures at the back of the air conditioner (the insulating gasket
must fit firmly against the wall) particularly in the zone where air
enters and leaves the machine.
WARNING-Please check the weight of the unit as it may
require 2 people to lift it into position, especially at high
level.
CHAP. 2.4 PREPARATION FOR ASSEMBLY/INSTALLATION WALL
TOP PART AT HIGH LEVEL
2.4.1 The air conditioner is assembled in the factory ready to
Introduction be installed low on the wall.
The air outlet, in this case, is at the top of the air conditioner with the
recycle grating and control panel. In order to prepare the product for
installation on the top part of the wall, follow the instructions below.
2.4.2
Removal of front
casing
Note: if the air conditioner has not been installed on the wall yet,
place it on its back. To not apply heavy pressure to the bottom of the
device as this could dent or scratch the casing.
Use a small blade screwdriver to remove the horizontal strips on the
casing, applying gentle leverage in the slits along the sides. (see fig.
15). Take care not to scratch the strips or casing with the
screwdriver point.
Unscrew the 8 self-threading screws that fasten the casing to the air
conditioner.
Lift the casing off carefully, pulling it toward you by about 50 cm (see fig.
16).
Disconnect the fastener on the right that fastens the wires to the airflow
deviation baffle adjustment motor (see fig. 17). Now you can remove the
casing completely.

2.4.3 Unscrew the bracket supporting the small circuit board with
Preparation of display LED’sand reinstall it on the bottom opposite, where
unit youwillfindtwoholesonthebase(seefig.18-19).
Make sure the connection plate is securely fastened on the
inside of the air conditioner, and apply some insulating tape if
necessary. Remove the styrofoam enclosure on the lower
right-hand side under the air recycle fan and fit it against the
opening above the fan (see fig. 20-21).
Remove the air outlet grating by removing the fastening screws.
Remove the control panel (see fig. 22).
When performing this operation place the casing on a
secure surface so as not to scratch or dent it. Remove the
plastic plate with the logo and transparent screen for display of
the LED’s from the control panel by pressing on the hooks at
the rear. Turn it over (rotate by 180°) and reinstall it on the
panel.
Reassemble the parts in the opposite position from the
original installation, reversing the air outlet grating with the
control panel grating.
Turn the casing over so that the air outlet grating is on the
lower right-hand side of the device. Connect the plug on
the step-step motor of the grating. Fit the casing back on the
air conditioner carefully, taking care to hold the wires for the step-
step motor to one side so that they do not interfere with the inner
part of the air outlet grating.
Check that all the coupling references of the casing with the
rear frame are fully inserted so that the casing is fitted
smoothly and evenly all around. Fasten the casing with its
eight screws and replace the strips in their slots.
After completing installation, the electronic parts of the air
conditioner have to be configured so as to take into account
the stratification of heat in the room. This procedure is outlined
in paragraph 2.5 (Operating tests and diagnosis of
possible malfunctions).
CHAP. 2.5 WORKING TESTS AND IDENTIFICATION
OFPOSSIBLEMALFUNCTIONS
The program introduced in the microprocessor of this
device makes it possible to run a brief self-test to ensure that
the machine functions normally by starting each of its
internal components.
To run the self-test, proceed as follows:
-Powerthe air conditioner and make sure it is on stand-by.–U
Use a sharp object to press the micro-key located under
the hole on the left of the control panel for at least 10
sec.
-At the beginning and end of the self-test procedure the status
of configuration of the machine will be displayed for a few
seconds as follows:

red LED (filter): off = UNICO
on = UNICO HP (with heat pump)
green LED (compr.): off = with correction of room tem-
perature
on = without correction of room
temperature
orange LED (timer): off = without correction of room
temperature
on = with correction of room tem-
perature
green LED (power): off = stand-by in case of blackout
on = restart in case of black-out
Should there be a jam in the air-conditioning system with alarm
signals according to the table here following, please be ready to
refer to the Service Centre which LED’s are blinking in order
to simplify their intervention.

The end of the self-test will be signalled by all the LEDs
lighting up at once and blinking ten times, as well as by an
acoustic signal.
At this time, you can adjust the temperature reading on
the room temperature sensor. This correction is important if
the air conditioner is installed high on the wall in a room
where the warm air tends to stratify upward (as in rooms
with high ceilings or other sources of heat besides the air
conditioner). The sensor will read a temperature 3°C lower
than the effective one, in this case, to compensate for
the difference between the lower inhabited part of the
room and the temperature at the height of the sensor. To
enter or remove this correction proceed as follows:
1 Check the status of the machine as described
previously, and if no correction has been made, press
the button on the console while the acoustic signal is
on at the end of the self-test.
2 To remove the correction, press the button while the
acoustic signal is on at the end of the self-test.

-Check after a few seconds to see whether the
equipment heats normally (if equipped with heat pump
function) for about 2 minutes and then, after a few
seconds, that it cools for another 2 minutes. Before
concluding the self-test, the electronic part tests the
temperature probes to make sure they are operating
normally. If any of these should not be working, the
corresponding signal led remains lit for 20 sec. (see
table on next page).

The machine is set in the factory without correction of
the temperature.
In addition to the self-test (that can be made under any
conditions of room temperature) we recommend that you also
test the product in the various operating modes accessible
to the user (see the user manual). One important test you
should make concerns regular evacuation of condensation
water on the models with heat pump. To check this, keep the
machine running for at least 4-5 hours in the heating mode. If
the water does not drain, there should be an “overflow”
alarm.

personnel arrives, you can drain the water out by following
these simple instructions:
-Grasp the rubber cap on the bottom centre of the air
conditioner behind the edge of the frame facing the wall
between your thumb and forefinger.
-Pull the rubber tube closed by the cap out by a few
centimetres.
-Remove the cap after placing a bucket or other container
underneath it (at least five litter capacity) to collect the water
(see fig. 23).
-After eliminating the malfunction the service personnel will
take care of closing the evacuation tube.
CHAP. 2.6 PERIODICAL MAINTENANCE
Air conditioners of this type do not require any particular routine
maintenance except::
Note: after cleaning the battery replace the noise
insulation carefully matching the edges and gaskets with
their reference markings.
Before you leave the site of installation you should gather up all
packing material and use a damp cloth to remove any traces of
dust that may have deposited on the machine during
assembly (fig. 24). These operations, though certainly not
essential, have a beneficial effect as they enhance the
professional image of the installer in the eyes of the client.
To prevent unnecessary calls by the user, before you leave the site
of installation it is also a good idea to:
-Explain the contents of the Instruction Manual to the user.
-Show him how to clean the filter.
-Explain when and how he should contact the Service
Department
Fig. 24
-Cleaning or washing the room air filter when the red
led lights up (see user manual).
-Cleaning of “external air” battery, to be done as needed,
depending on the amount of dirt in the external air,
once or twice a year. To do this, you must, of course, open
the air conditioner by removing its casing and the
noise insulation on the inside.
-Cleaning can be done using a vacuum cleaner or soft
brush, taking particular care not to damage the
aluminium heat exchanger baffles. It may be necessary to
use water and detergents to remove heavily encrusted
dirt.

CHAP 2.7 INSTRUCTIONS TO INSTALL THE FRESH AIR KIT KR100
The fresh air kit allows the outside air to enter into the room where the air
conditioner is located.
This device guarantees that about 90 m3/h are brought into the room,
resulting in a very good change of air.
Follow carefully these instructions and you will be able to install perfectly the
appliance.
NOTICE
•The kit has to be mounted to the wall before the air conditioner
•It have to be installed on an outside wall, preferably not on the walls looking
onto a road or places where there are polluting substances
•The minimum height from the ground must be at least 6 metres for walls
looking onto high traffic-congested roads and 3 metres in all the other cases.
•Check that nothing could obstruct the airflow at the device inlet (trees with
leafs, curtains, etc..)
•To improve the air downflow from the room it is recommended to install a
plenum lock-gate with approx. dimensions 150x150 mm.
INSTALLATION
After having determined the position of the indoor unit fixing bracket, trace the centre of
the hole following the instructions of picture 1.
•Drill the wall using a suitable drill equipped with core bit with a diameter of at least
132 mm. The hole has to be perfectly horizontal, or at the most having a slight
inclination toward outside.
•Put the 130-mm. pipe into the hole, after you cut it according to the wall thickness.
ATTENTION: the pipe supplied with the kit is long max. 500 mm; for thicker
walls you have to ask for a longer pipe to the Service Centres.
•Seal the pipe at both ends using some silicone or stopper
•Apply the outdoor grid, equipped with grate against insects, by means of at least 2
dowels diam. 6 (supplied with the kit) and putting silicone between the wall and rear
part of the grid before fixing it.
•Put the fan/lock-gate assembly in the hole from inside the room, leaving the power
cable in the lower part (picture 3). Take the inside protection grid away, fix the device
to the wall with at least two dowels diam. 6 and then reassemble the grid.
•Now install the indoor unit following the user manual’s instructions; before closing the
front panel, connect the connection cable to the kit as follows:
oLet the cable pass through the special hole that is placed on the rear casing
as shown in picture 2 and position the fairlead that is already threaded on
the connecting cable
Calculate the length of the pipe bringing it near the male connector placed on the
electronic board and put the terminals in the special female connector supplied with the
kit.
Connect the connector to the electronic board.
Close the front panel and test the working of the air conditioner.
