3.1. Cleaning the filters and the indoor unit
Cleaning the filter
•Clean the filter using a vacuum cleaner. If you do not have a vacuum
cleaner, tap the filter against a solid object to knock off dirt and dust.
•If the filter is especially dirty, wash it in lukewarm water. Take care to
rinse off any detergent thoroughly and allow the filter to dry completely
before putting it back into the unit.
Caution:
•Do not dry the filter in direct sunlight or by using a heat source,
such as an electric heater: this may warp it.
•Do not wash the filter in hot water (above 50°C), as this may warp
them.
•Make sure that the air filter is always installed. Operating the unit
without air filter can cause malfunction.
Cleaning the indoor unit
•Wipe the outside of the unit with a clean, dry, soft cloth.
•Clean off any oil stains or finger marks using a neutral household deter-
gent (such as dishwashing liquid or laundry detergent).
Caution:
Never use gasoline, benzene, thinner, scouring powder or any type of
non-neutral detergent, as these substances may damage the unit’s
case.
Before you call out a repair man, check the following table to see whether there is a simple solution to your problem.
[for wireless remote controller]
Problem
Unit does not operate at all.
No indication of wireless remote con-
troller, indication is dim, or signal
transmission cannot reach remote
controller sensor.
Problem
Unit does not start immediately.
The operating display of the wireless
remote controller’s receiver is flash-
ing.
Solution
Wait until the unit restarts automati-
cally. The compressor may hesitate
resuming because a three-minute
resume prevention circuit is incorpo-
rated in the outdoor unit for protec-
tion of the compressor.
A self-diagnostic function is being
performed to preserve the air condi-
tioner.
* Do not attempt to make repairs
yourself. Turn the main switch off
and contact the dealer from whom
you bought the air conditioner. Pro-
vide him or her with the name of
the unit and the information dis-
played in the remote controller.
Solution
Turn main power on. Then press the
POWER ON/OFF button to turn the
unit on.
Wait until power is restored, then
press the POWER ON/OFF button
to turn the unit on.
The batteries have run out.
Replace the batteries with new ones
(size AAA), and then press the reset
button. Though both alkaline batter-
ies and manganese batteries can be
used, alkaline batteries are recom-
mended because their service life is
longer than that of manganese bat-
teries.
* If indication is not detected even
when new batteries have been re-
placed, check that the batteries
have been installed properly.

Installation place
Avoid installing the air conditioner in the following places.
•Where flammable gas could leak.
Caution:
Do not install the unit where flammable gas could leak.
If gas leaks and collects around the unit, it may cause an explosion.
•Where there is much machine oil.
•Salty place such as the seaside.
•Where sulfide gas is generated such as a hot spring.
•Where there is oil splashing or much oily smoke.
Warning:
If the air conditioner operates but does not cool or heat (depending
on model) the room, consult your dealer since there may be a refrig-
erant leak. Be sure to ask the service representative whether there is
refrigerant leakage or not when repairs are carried out.
The refrigerant charged in the air conditioner is safe. Refrigerant nor-
mally does not leak, however, if refrigerant gas leaks indoors, and
comes into contact with the fire of a fan heater, space heater, stove,
etc., harmful substances will be generated.

5. Installation, relocation and inspection
Problem
Unit does not cool or heat very well.
The unit stops operating before ar-
riving at the set temperature in the
heating mode.
The airflow direction suddenly
changes.
A white mist is expelled from the in-
door unit.
The indicators of the remote control-
ler do not light up when operated.
Problem
CENTRALLY CONTROLLED is dis-
played in the remote controller.
The start and stop functions are not
available just after restarting the unit.
“PLEASE WAIT”is displayed in the
remote controller.
An error code is displayed in the re-
mote controller.
Solution
The start and stop functions of the
remote controller are not available
when the CENTRALLY CONTROL-
LED message is lit.
Wait about three minutes (operation
has stopped to prevent damage to
the air conditioner).
An automatic startup test is being
performed (will last for about two min-
utes).
A self-diagnostic function is being
performed to preserve the air condi-
tioner.
* Do not attempt to make repairs
yourself. Turn the main switch off
and contact the dealer from whom
you bought the air conditioner. Pro-
vide him or her with the name of
the unit and the information dis-
played in the remote controller.
Solution
Clean the filter.
Frost forms when the outdoor tem-
perature is low and humidity is high.
Wait for about 10 minutes for the
frost to melt.
After one hour of cooling-mode op-
eration with the airflow in a down-
ward direction, the unit will automati-
cally change to the “Horizontal air-
flow”mode.
When the unit is in the heating or de-
frosting mode, it will automatically
change to the “Horizontal airflow
mode”.
This may occur just after the unit is
turned on when a high level of hu-
midity is present in the room.
Turn on the power switch. “”will
be displayed.
[for wired remote controller]
If none of the above apply, turn the main switch off and contact the dealer from whom you bought the air-conditioner, telling him the model name and the
nature of the problem. Do not try to fix the unit yourself.
In any of the following cases, turn off the main power switch and contact your local dealer for service:
•The operation lamp (on the main unit or the remote controller) flashes.
•The switches do not work properly.
•The circuit breaker trips frequently (or the fuse blows frequently).
•Water has accidentally been splashed into the unit.
•Water leaks from the unit.
•Something is accidentally dropped into the air-conditioner.
•An unusual noise is heard during operation.
The following do not indicate any malfunction:
Odours: smells such as tobacco or cosmetic odours may persist after they have been sucked into the unit.
Sound of liquid flowing inside indoor unit: this can occur during or after operation and is simply the sound of refrigerant being circulated inside the unit.
Ticking sound coming from indoor unit: this can occur when cooling or heating has just begun or has just stopped. It is caused by the indoor unit shrinking
or expanding slightly due to the change in temperature.
The message “CENTRALLY CONTROLLED”appearing on the LCD panel: from time to time, this message may come up on the LCD panel. This does
not indicate any malfunction.
4. Troubleshooting

Indice
sLeggere attentamente la sezione “Misure di sicurezza” prima di far funzionare l’unità.
sLa sezione “Misure di sicurezza” contiene informazioni importanti sulla sicurezza di funzionamento dell’unità. Accertarsi che vengano seguite perfetta-
mente.
sPrima di collegare l’equipaggiamento alla rete di alimentazione, contattare o chiedere l’autorizzazione dell’autorità competente.
Simboli utilizzati nel testo
Avvertenza:
Descrive le precauzioni da prendere per evitare il rischio di lesioni, anche mortali, per l’utente.
Cautela:
Descrive le precauzioni da prendere per evitare il danneggiamento dell’unità.
Simboli utilizzati nelle illustrazioni
: Indica un’azione da evitare.
: Indica la necessità di rispettare un’istruzione importante.
: Indica la necessità di collegare un componente a massa.
: Indica che occorre operare con grande cautela con le parti rotanti.
: Indica che l’interruttore principale deve essere disattivato prima di effettuare la manutenzione.
: Attenzione alle scosse elettriche.
: Attenzione alle superfici roventi.
Avvertenza:
Leggere attentamente le etichette attaccate all’unità principale.
Avvertenza:
• L’unità non deve essere installata dall’utente. Richiedere al distributore o ad una società autorizzata di installare l’unità. Se l’unità non è installata correttamen-
te, vi è il rischio di perdite d’acqua, di scosse elettriche o di incendio.
• Non salire e non appoggiare alcun oggetto sull’unità.
• Non spruzzare acqua sull’unità e non toccarla con le mani bagnate. Ciò può provocare una scossa elettrica.
• Non spruzzare gas combustibile nei pressi dell’unità, per evitare il rischio di un incendio.
• Non piazzare un riscaldatore a gas o qualsiasi altro apparecchio a fiamma aperta in un luogo esposto all’aria scaricata dall’unità. Ciò può essere alla base di
una combustione incompleta.
• In caso di perdite di refrigerante durante il funzionamento, ventilare la stanza.
Se il refrigerante viene a contatto con fiamme vengono esalati gas tossici.
• Non rimuovere il pannello anteriore o la griglia di protezione del ventilatore dalla sezione esterna durante il funzionamento dell’unità. Un eventuale contatto con
le parti rotanti, roventi o ad alta tensione può infatti causare conseguenze gravi.
• Non inserire le dita, oggetti appuntiti, ecc..., nei fori di entrata o di uscita dell’unità per evitare di ferirsi, in quanto il ventilatore all’interno dell’unità ruota ad alta
velocità.
• In presenza di odori particolari, arrestare il funzionamento dell’unità, spegnere l’interruttore di alimentazione e contattare il proprio distributore.
• Il climatizzatore NON può essere usato da bambini o persone inferme senza la sorveglianza appropriata.
• È opportuno sorvegliare i bambini piccoli affinché non giochino con il climatizzatore.
Cautela:
• Non usare alcun oggetto appuntito per premere i pulsanti, in modo da non danneggiare il comando a distanza.
• Non bloccare o coprire gli ingressi o le uscite interni od esterni dell’unità.
Eliminazione dell’unità
Se occorre eliminare l’unità, contattare il proprio distributore. Nel caso in cui i tubi siano rimossi in modo non corretto, il refrigerante (gas fluorocarburo) può infatti fuoruscire
e venire a contatto della pelle, con conseguenze gravi. Il rilascio di refrigerante nell’atmosfera è inoltre dannoso per l’ambiente.

Informazioni relative al condizionatore dell’aria multi system
(Sezione esterna: serie MXZ)
ss
ss
sCondizionatore dell’aria Multi System (sezione esterna: serie MXZ) puòcol-
legare piùdi due unitàad una singola sezione esterna. Conformemente alla
capacità, èpossibile far funzionare simultaneamente piùdi due sezioni in-
terne.
•Quando si cerca di far funzionare piùdi due sezioni interne simultaneamente ad
una singola sezione esterna, una per il raffreddamento e l’altra per il riscaldamen-
to, viene selezionata la modalitàdi funzionamento della sezione interna che fun-
ziona per prima. L’altra sezione interna che inizieràa funzionare successivamen-
te, arresteràil suo funzionamento e verràindicato il messaggio.
In questo caso, si prega di impostare tutte le sezioni interne nella stessa modalità
di funzionamento.
•Quando l’unitàinterna funziona in modalità(AUTO), puòaccadere che non
riesca a passare alla modalitàdi funzionamento (RAFFREDDAMENTO ↔RISCAL-
DAMENTO); in questo caso l’unitàentreràin stato di attesa (standby).
•Quando la sezione interna inizia a funzionare una volta completata la fase di
sbrinamento della sezione esterna, ci vorranno alcuni minuti (max.circa 15 minuti)
prima che venga soffiata aria calda.
•In modalitàriscaldamento, se la parte superiore della sezione interna diventa cal-
da o viene percepito il rumore causato dal flusso di gas, non si èin presenza, nei
due casi, di un malfunzionamento. Il motivo èda ricercarsi nel fatto che il gas
refrigerante scorre continuamente all’interno della sezione interna anche questa
non sta funzionando.
