SPECIFICHE DI SMALTIMENTO:
Il climatizzatore è contrassegnato con questo simbolo,
ciò significa che i prodotti elettrici ed elettronici non
possono essere smaltiti insieme ai rifiuti domestici non
differenziati. Non cercare di demolire il sistema da soli:
la demolizioni dei sistemi di condizionamento, nonché il
recupero del refrigerante, dell’olio e di qualsiasi altra
parte devono essere eseguiti da un installatore qualifi-
cato in conformità alla legislazione locale e nazionale
vigente in materia.I climatizzatori devo essere trattati presso una struttura spe-
cializzata nel riutilizzo, riciclaggio e recupero dei materiali. Il corretto smaltimen-
to del prodotto eviterà le possibili conseguenze negative all’ambiente e alla
salute dell’uomo. Per maggiori informazioni contattare l’installatore o le autori-
tà locali. Le batterie devono essere tolte dal telecomando e smaltite separata-
mente conformemente alla legislazione locale e nazionale vigente in materia.

outlet.
Cautions
3. If the fuse on PC board is broken please change
it with the type of T 3.15A /250VAC or T
25A/250VAC.
Please check the circuit diagram about the fuse
replaced.
4. The wiring method should be in line with the
local wiring standard.
5. The power cable and connecting cable are self-
provided. All the cables shall have got the local
authentication certificate. During installation, when
the connecting cables break off, it must be assured
that the grounding wire is the last one to be broken
off.
6. The breaker of the air conditioner should be all-
pole switch; and the distance between its two
contacts should be no less 3mm. Such means for
disconnection must be incorporation in the fixed
wiring.
7. The waste battery shall be disposed properly.
All electrical repairs must be carried out by
qualified electricians. Inadequate repairs may result
in a major source of danger for the user of the air
conditoiner.
Do not damage any parts of the air conditioner
that carry refrigerant by piercing or perforating the
air conditioner's tubes with sharp or pointed items,
crushing or twisting any tubes, or scraping the
coatings off the surfaces. If the refrigerant spurts
out and gets into eyes, it may result in serious eye
injuries.
Do not obstruct or cover the ventilation grille
of the air conditioner. Do not put fingers or any
other things into the inlet/outlet and swing louver.
Do not allow children to play with the air
conditioner. In no case should children be allowed
to sit on the outdoor unit.
Specifications
The refrigerating circuit is leak-proof.
1. Applicable ambient temperature range:
The machine is adaptive in following
situation
2. If the supply cord is damaged, it must be replaced

All units shall be earthed. The earth must not be connected to a gas pipe, water pipe, or telephone line.
Poor earthing could cause electric shock.
Be sure to install a circuit breaker to avoid electric shock.
Arrange water drainage according to this manual. Cover pipe with insulation materials to prevent
condensation occuring. Improper installation of water drainage will cause water leakage.
Installation work must be carried out by professional qualified people, do not install the unit by yourself.
Incorrect installation will cause water leakage, electric shock and potentially fire.
Install the unit as per the manual. Incorrect installation will cause water leakage, electric shock or
fire risk.
Be sure to use specified accessories and parts. Otherwise, water leakage, electric shock, fire risk or unit
falling down may occur .
Mounting position must be strong enough to hold the unit. Or, the unit will potentially fall down causing
injuries.
When installing the unit, take in consideration storms and high winds. Incorrect installation may cause
the unit to fall down.
All electric work should be carried out by experienced personnel as per current regulations and this
manual. Incorrect installation or undersized electric cable may cause electric shock or fire risk.
All circuits must be earthed. Ensure that no external forces will affect the terminal block and electric
cable. Poor wiring and installation may cause fire risk.
Arrange wire connection between connecting the indoor and outdoor power supply correctly. Fix terminal
cover firmly to avoid overheating, electric shock or even fire risk.
In the case of a refrigerant leakage during unit installation, keep the room well ventilated.
Check the unit upon installation. Be sure there is no leakage. Refrigerant will induce a poisonous gas
subject to heat.
Isolate power supply before touching terminal block.
To ensure proper installation, please read this safety precautions carefully before the installation. After
installation, start the unit correctly and ensure that you show the customer how to operate and maintain
the units.
WARNING!
CAUTION! Incorrect operations may result in injuries or machine damages; in some cases may cause
serious consequences.
Incorrect operations may result in severe consequences of death or serious injuries.
To maintain good picture or reduce noise, keep the unit at least 1m from T.V. or radio, when installing
the communication wire and power supply. (If the radio wave is relatively strong, 1m is not enough to
reduce the interference).
Do not install the unit in following places:
(a) Oil mist or oil gas exists, such as kitchen, or, plastic parts may age, or water leakage.
(b) Where there is corrosive gas. Copper tube and welded part may be damaged due to corrosion
causing leakage.
(c) Where there is strong radiation. It will affect the unit's control system, causing malfunction of the
unit.
(d) Where there are flammable gas, dirt, and volatile matter (thinner, gasoline) exist, these items will
cause a fire risk.

without connecting the indoor unit in ordor to add another indoor unit later. Make sure no dirt or mositure
gets into eigher side of the embedded branch piping.
2.It is impossible to connect the indoor unit for one unit only. Be sure to connect at least 2 units.
Installation sketch map is illustrated for
example model AU362XHERA.

If there is the danger of
the unit falling or
overturning, fix the unit
with foundation bolts,
or with wire or other means.
If the location does not have good drainage, place the unit on a level mounting base(or a plastic pedestal).
Install the outdoor unit in a level position. Failure to do so may result in water leakage or accumulation.

Installation procedure
14
Before inserting power plug into receptacle, check the voltage without fail. The power source is the same
as the corresponded name plate.
Install an exclusive branch circuit of the power.
A receptacle shall be set up in a distance where the power cable can be reached. Do not extend the cable
by cutting it.
2.Selecting a location for installation of the indoor units
The maxinum allowable length of refrigerant piping, and the maxmum allowable height difference
between the outdoor and indoor units, are listed below.
(The shorter the refrigerant piping, the better the performance. Connect so that the piping is as short as
possible. Shortest allowable length per room is 3m)
1.Precautions on installation
Check the strength and level of the installation ground so that unit will not cause any operating vibration
or noise after installation.
In accordance with the foundation drawing in fix the unit securely by means of the foundation bolts.
It is best to screw in the foundation bolts unit their length are 20 mm from the foundation surface.
