Fig.1

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 panelling, 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.
T o make these calculations, refer directly to the regulations
in effect (UNI ref. Law 10/91) or to the tables, both printed
and computerized, based on those regulations.
For particularly significant applications, we recommend
contacting expert heating engineers.

UNICO-HE

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).

2.3.1

Drilling the wall

INSTALLATION OF THE UNIT

This operation should be carried out using the proper tools
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.
T o 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.
Our Service Department can give you all necessary
information to enable you to find 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.
Using a core boring head measuring at least 154 mm 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

31

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).

Fig. 6

32

UNICO-HE

2.3.2

Provision for

draining con-

densate for

machines with

heat pump.

When the machine is heating, it produces condensate
that has to be eliminated through a specific drain line,
otherwise the machine will not work. Drainage occurs by
gravity . For this reason, it is essential for the drain line to
have a minimum inclination of at least 3% throughout its
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).

2.3.3

Installation of air

pipes and

external

gratings

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.
This pipe 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.

After drilling the holes, the plastic pipes supplied with the
air conditioner have to be fitted through them. The pipe
with insulation on the inside has to be fitted in the right­hand hole with the insulated part toward the inside as
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).

300 mm

Fig. 7

Fig. 8

UNICO-HE

The tube diameter is nearly the same as those carried
out using the 152/154 mm nominal diameter core drill. In
order to introduce the tubes, they must therefore 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.

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

Fig. 10

33

To position the external grating, proceed as follows:

- Grasp the two rubber belts attached to the grating in
one hand.

- Fold the outer gratings in half by grasping them with
your free hand along the fold line and inserting your
fingers inside the fins (fig. 11).
Insert your arm inside the pipe until the grating
protrudes all the way outside.

- Let the grating open, but keep your fingers inside the
fins.

- Turn the grating so that the fins are perfectly horizontal
with the inclination toward the outside (fig. 12).

- Pull the grating toward you.

- Tighten the rubber belts and fasten them to the two
pins on the inner flange.

- Cut the excess part of the belt.

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.

Fig. 10/1

2.3.4

Power supply

connection

The air conditioner is equipped with a power supply cable
and plug.
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).

T o 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.

Fitting the unit

on bracket

CHAP. 2.4

After checking again that the fastening bracket is securely
fastened to the wall, and that any necessary preparations
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.

T o 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.

Introduction

2.4.2

Removal of front

casing

The air conditioner is assembled in the factory ready to
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.

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.

Preparation of

unit

Unscrew the bracket supporting the small circuit board with
display leds and reinstall it on the bottom opposite, where
you will find two holes on the base (see fig. 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 leds 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, t aking
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).

- 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

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 black-

out

on = restart in case of black-out

- 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).

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 leds 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 importan t
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.

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.

Evacuation of

condensation

water in case of

emergency

CHAP. 2.6

If there should be a malfunction in the condensation water
drain system, the air conditioner stops working and
signals, with flashing orange, green and red lights (the
second and third leds from the left), the alarm status.
T o enable the air conditioner to work temporarily until the
service 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.

PERIODICAL MAINTENANCE

Air conditioners of this type do not require any particular
routine maintenance except:

- 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.

Fig. 23

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.

T o 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

CHAP. 3.1

Important Recommendations

Installation and connection of the air conditioner should
be carried out by specialized personnel in possession
of the qualifications specified in Law 46/90.
The instructions for installation are provided in the
specific manual.

No structural object (furniture, curtains, plants, leaves,
blinds, etc.) should ever obstruct the normal flow of
air from either the internal or external gratings.

Never lean or, worse yet, sit on the casing of the air
conditioner as this could cause serious damage to
the external parts.

Do not turn the horizontal airflow baffles by hand.
Always use the remote control to adjust baffle
position.

If the unit leaks water, switch it off immediately and
disconnect it from the power mains. Call the nearest
service centre.

When the air conditioner is heating, it has to
periodically eliminate any ice that could form on the
external battery. While it is doing this, the machine
keeps running but does not heat the room. This lasts
for a brief period of time, from 3 to a maximum of 10
minutes.
