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.
CHAP. 2.2
SELECTION OF POSITION OF THE 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 and on the air outlet side especially, there should
be no obstacles closer than 2 m (this could cause turbulence that
would interfere with correct 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
2.2.1
communicates with the outside.
Choice of best
position for
installing the air
conditioner
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.).
2.2.2
Dimensions and
features of site
where air
conditioner is
installed
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 to the tables, both printed and
computerized, based on those regulations. For particularly
significant applications, we recommend contacting expert
heating engineers.
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 airconditioned 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
2.3.1
INSTALLATION OF THE UNIT
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.
Using a core boring head measuring at least 158 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
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
Provision for
draining condensate 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).
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.
2.3.3
Installation of air
pipes and
external
gratings
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 right
hand 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).
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
Fig 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
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). 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
Preparation of
unit
Unscrew the bracket supporting the small circuit board with
display LED’s 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 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 stepstep 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
OF POSSIBLE MALFUNCTIONS
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:
- Power the 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):
green LED (compr.):
orange LED (timer):

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 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

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.
2.5.1
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.
To 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.
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

3.3 CONTROL OF AIR CONDITIONER USING
THE REMOTE CONTROL UNIT
3.3.1 The remote control supplied with the air conditioner is
Remote control designed to be extremely sturdy and to ensure excellent
performance in use, but it should nevertheless be handled with
some care.
For example, do not:
- leave it out in the rain, spill water on its keyboard or drop it
into water.
- subject it to impacts or drop it onto hard surfaces.
- leave it exposed to direct sunlight.
- place obstacles between the remote control and
the air conditioner while using it.
Furthermore:
- if other devices operated by remote control (TV, radio, stereo
systems, etc.) are located in the same room as the air
conditioner, there may be interference.
- electronic and fluorescent lighting may interfere with
communications between the remote control and the air
conditioner.
- remove the batteries in case of prolonged disuse of the
remote control.
3.3.2 Use only 2 dry cell batteries type LR03 with 1,5 V (supplied
Insertion of with the remote control unit). Dispose of used batteries
batteries only at the special collection points provided by the local
authorities for this type of waste.
REPLACE BOTH BATTERIES AT THE SAME TIME
To insert the batteries remove the spring-latch cover on the
back of the remote control.
The batteries have to be inserted according to the positive and
negative pole markings in the bottom of the battery compartment.
Close the spring-latch cover after inserting the batteries.
3.4 REMOTE CONTROL

Cooling function
This button turns the machine on or off.
The machine’s control system has a memory, therefore
any setting will not be lost when it is turned off.
This button serves to switch the air conditioner on or off for brief
periods of time. In case of prolonged stop of the machine,
it must be deactivated turning the main switch off or
unplugging the machine from the mains.
By means of this button the machine is automatically
regulated in order to create an optimal comfort temperature in the air-conditioned room.
The machine’s temperature is automatically regulated
according to the room’s temperature.
The fan speed is also automatically regulated according to the
set temperature (except in dehumidification use).
When used in this mode, the air conditioner dehumidifies
and cools the room.
Button T4 is used to select the operating mode.
Press until the snowflake symbol appears on the display. First set
the desired temperature and fan speed (see the relative
paragraphs).
After three minutes (maximum time), the compressor should
start up and the air conditioner should start cooling the room.
When the compressor starts you will see a green LED light
up on the control panel.
Fig. 30
Cooling function
3.4.6
Dehumidifier only
When used in this mode, the air conditioner only
eliminates the humidity in the room, practically without
changing the temperature. This function can be extremely
useful between seasons, particularly on rainy days when
the temperature is not uncomfortable but the excess
humidity feels unpleasant.
When used in this mode, the air conditioner ignores the
temperature and fan speed settings, which are not shown
on the display in this case.
To operate the air conditioner in this mode, press Button
T4 until the droplet symbol appears on the display with
automatic ventilation.
In this operating mode it is normal for the air conditioner to
function intermittently.
3.4.7 When used in the mode the air conditioner does not act on the
Fan Only either the temperature or the humidity in the room, but only
keeps the air in circulation. This operating mode is
selected by pressing button T4 until the fan symbol
appears on the display. At this stage you can select the
fan speed (see paragraph 3.4.10).
3.4.8
Heating function
(only models with
heat pump)
When used in this mode the air conditioner heats the
room. This function is only available on models with a
heating pump (HP).
To select this mode press button T4 (operating mode
selection switch) until the sun symbol appears on the
display. First set the desired temperature and fan speed (see
the specific paragraphs). After three minutes (maximum
time) the compressor should start and the air conditioner starts
heating the room. When the compressor starts you will see a
green LED light up on the control panel.
Note: The air conditioner has to defrost its battery
periodically (about once every half hour). During this
operation (about 3-8 minutes) the air conditioner does
not heat the room, though its internal parts remain on
except for the room air fan.
When the outdoor
temperature is very low, there may be a slight delay
(about 3 minutes) for passage from the minimum to the
medium or maximum speed from when the command is
sent to the machine with the remote control.
3.4.9
Control of air flow
Direction
Fig. 32
Fan only
The airflow can be controlled in both its horizontal and
vertical direction. Control of the horizontal direction cannot
be carried out with the remote control and must be made
manually by adjusting the position of the fins on the outlet
opening.
Fig. 33
Heating function (only models with heat pump)
IMPORTANT: Adjustment of horizontal airflow should only
be made when the movable grille is not moving.
Fig. 34
Control of air flow direction
To adjust vertical airflow you can operate in two ways:
- continuous oscillation of airflow, obtained by pressing
button T9 which starts and stops the movable grille. This
enables the fins on the
grille to turn completely around.
- stop the movable grille in the desired position by pressing
button T9 again while the fins are in motion.
Pressing button T9 will start automatic turning of the baffle.
IMPORTANT: The baffle must not be turned by hand.
3.4.10
Control of fan
speed
Fan speed is controlled by button T5.
Pressing this button gives the following sequence:
once=Low, twice=Medium, three times=High, four
times=Automatic.
The higher the speed setting, the greater the output of the
air conditioner but also the louder its operation. If you select
Automatic mode, the microprocessor in the air conditioner
adjusts the speed automatically, keeping it as high as needed
to reach the temperature setting with respect to the
effective room temperature. As the room temperature
nears the setting, fan speed is reduced automatically.
When the unit is operating in dehumidification mode, fan
speed adjustment is not possible as it can only function at
low speed.
Fig. 35
Control of fan speed
3.4.11
External air intake
This function is available only on devices equipped with
the optional external air intake, that is an exclusive feature for
this type of air conditioner. Press button T8 once to start the
microfan on the external air intake and open the shutter to
refresh the air in the room.
Press button T8 again to close the shutter.
It should be borne in mind that opening the external air intake
reduces the cooling effect of the air conditioner.
This is also true of the heating effect for machines equipped
with a heat pump. For this reason, if you want to maintain a
constant flow of external air with the air conditioner in
operation, you should first make sure your unit is powerful
enough to operate this way.
If not, you should close the external air intake when the
temperature outside is extreme.
Fig. 36
External air intake
3.4.12 Use button T3 to select Night comfort Mode, which includes
Night Comfort the following functions:
mode
- Gradual increase of the temperature set for coding.
- Gradual reduction of the temperature set for heating
(only HP models).
- Reduction of noise level.
- Lower energy consumption at night.
To select Night comfort mode press button T3 after selecting
the operating mode using button T4 and setting the
temperature using button T7. Ideally, you should start
night well-being mode operation just before you fall
asleep.
In cooling mode, the set temperature is held for one hour after
starting Night comfort mode operation. For the next hour, the
setting is allowed to increase gradually up to 2°C over the
original setting, while the fan speed setting is low.
After the second hour, the temperature and fan speed
settings are not changed.
In heating mode, the set temperature is held for one hour after
starting Night well-being mode operation. For the next hour the
setting is lowered gradually to 4°C below the original while the fan
speed setting is low. After the second hour, the temperature
and fan speed settings are not changed.
Night comfort mode operation is not available for
dehumidifying only.
Night comfort mode operation can be halted at any time
(ideally when you wake up in the morning) by pressing
button T3 again.
At this stage the temperature and fan speed settings made
prior to starting Night comfort mode operation go back into
effect.
3.4.13
Setting programs

MAINTENANCE
Your air conditioner has been designed to reduce
operations of routine maintenance to a minimum and
ensure that they can be performed easily by any user. The
only operations required are the three types of cleaning
illustrated below.
3.5.1
Cleaning air
filter
To ensure effective internal air filtration and satisfactory
operation of your air conditioner, the air filter has to be
cleaned periodically.
The need to perform this important operation is signalled after a
prolonged period of use by a red led lighting up on the control
panel (see fig. 26).
The filter is located on the front of the air intake grating on
the back of the machine.
To remove it, press on the two fastening hooks and pull the
filter toward you (see fig. 42). Wash the filter by forcing a
jet of water in the opposite direction from that of dust
accumulation.
In case of dirt that is hard to remove (such as grease or other
encrusted dirt) you may have to soak the filter first in a solution
of water and neutral detergent. Before replacing the filter
shake it to eliminate the wash water.
The last part of this operation consists of briefly pressing, with a
sharp object, the microkey located on the control panel.
The red led goes off and lights up again after the air
conditioner has been in operation for a few days.

3.6 TROUBLESHOOTING
It is extremely important for the user to know when behaviour
that seems like a malfunction really isn’t. Among these are some
(that we will indicate) that the user can easily correct following our
simple instructions, while in other cases it is necessary to get in
touch with our service personnel.
We also wish to remind you that any attempts to repair the
equipment made by unauthorized personnel will immediately
invalidate the warranty.

CHAP. 3.7
The compressor does not start up again immediately after
a stop (it takes about three minutes to start again).
The operating logic of the device provides for a delay
between stoppage of the compressor and starting up
again.
This is to safeguard the compressor.
- When heating, on versions with the heating pump, the machine
does not start emitting heat until a few minutes after the
compressor starts. If the fan should go into operation at the same
time as the compressor, for the first few minutes it would emit cold
air into the room (and this could disturb the occupants) as the
heating function needs some time to warm up.
This is why the fan startup is delayed until after the
compressor has started.
RECOMMENDATIONS FOR
ENERGY SAVINGS
- Always keep the filters clean (see chapter on maintenance
and cleaning).
- Keep the doors and windows closed in the air conditioned
rooms.
- Keeps sunlight out of the room by using curtains, lowering the
shades or closing the shutters.
- Do not obstruct the air flow (intake and outlet) on the units; this
in addition to reducing the performance of the system, will jeopardize
correct operation and could cause irreparable damage.
CHAP. 3.8 TROUBLESHOOTING
In case of malfunctions of the air-conditioner, check the items in the table below
If, after making the suggested check the problem is not solved, contact your authorized service centre.
- The air conditioner does not switch on. This may be due to:
- lack of power;
what to do:
- Make sure power is being supplied (by switching on a light in the house, for example).
- Make sure the main circuit breaker is closed and the fuse is not burnt out (replace the fuse if necessary.
If instead of a circuit breaker you have installed a cutoff switch, make sure it has not been tripped (reset it if necessary).
If the problem persists, contact our Service Department and do not try to start the air conditioner.
- The batteries in the remote control are dead.
If the batteries are dead you will notice the absence of indications on the display and the failure of the air conditioner to beep when
you try to send it a command. In this case, replace the batteries.
- The device no longer cools satisfactorily, this could be due to:
- The temperature set on the remote control being too high or too low (for models with heat pump);
what to do:
- check and, if necessary, correct the temperature setting on the remote control.
- The air filter is clogged before the alarm indicator lights up.
what to do:
- check and clean if necessary..
- Something is obstructing the airflow to the inside or to the outside;
what to do:
- remove anything that could obstruct airflow.
- There has been an increase in the heating or cooling load (for example a door or window has been left open or a device
that dissipates a large amount of heat has been installed in the room);
what to do:
- make sure the doors and windows are closed; if a heat source has been installed in the room that raises the temperature
excessively and for which the air conditioner is unable to compensate, the only solution is to install another air conditioner
or replace the existing one with a more powerful model.
- The air conditioner stops and the second and third led from the left on the control panel (orange, green and red lights) start flashing;
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.
To 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. - After
eliminating the malfunction the service personnel will take care of closing the evacuation tube.
IMPORTANT: If you are unable to classify the problem as one of those described above, you should
immediately get in touch with Compact Solutions without attempting to make any repairs yourself.
