WARNING
• Carefully read the Safety Precautions before installation.
• In certain functional environments, such as kitchens, server rooms, etc., the use of specially
designed air-conditioning units is highly recommended.
• This appliance can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the appliance in a safe way and understand
the hazards involved. Children shall not play with the appliance. Cleaning and user
maintenance shall not be made by children without supervision.
• Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacturer.
• Only trained and certified technicians should install, repair and service this air
conditioning unit.
Improper installation may result in electrical shock, short circuit, leaks, fire or other damage to
the equipment and personal property.
• Strictly follow the installation instructions set forth in this manual.
Improper installation may result in electrical shock, short circuit, leaks, fire or other damage to
the equipment.
•Before you install the unit, consider strong winds, typhoons and earthquakes that might aect
your unit and locate it accordingly. Failure to do so could cause the equipment to fail.
•After installation, ensure there are no refrigerant leaks and that the unit is operating properly.
Refrigerant is both toxic and flammable and poses a serious health and safety risk.
An all-pole disconnection device which has at least 3mm clearances in all poles , and have a
leakage current that may exceed 10mA, the residual current device (RCD) having a rated residual
operating current not exceeding 30mA, and disconnection must be incorporated in the xed
wiring in accordance with the wiring rules.

installation of pipe-work shall be kept to a minimum X m²(Please see the following form ).
The appliance shall not be installed in an unventilated space, if that space is smaller than X m²
(Please see the following form ).Spaces where refrigerant pipes shall be compliance with
national gas regulations.
• Any person who is involved with working on or breaking into a refrigerant circuit should hold a
current valid certicate from an industry-accredited assessment authority, which authorises their
competence to handle refrigerants safely in accordance with an industry recognised assessment
specication.
• Servicing shall only be performed as recommended by the equipment manufacturer.
Maintenance and repair requiring the assistance of other skilled personnel shall be carried out
under the supervision of the person competent in the use of ammable refrigerants.
• Appliance shall be stored in a well-ventilated area where the room size corresponds to the room
area as specied for operation.

an operating gas appliance) and ignition sources (for example an operating electric heater).
• The appliance shall be stored in a room without continuously operating ignition sources
(for example: open ames, an operating gas appliance or an operating electric heater).
• Do not pierce or burn.
• The appliance shall be stored so as to prevent mechanical damage from occurring.
•
• Be aware that the refrigerants may not contain an odour.
• Keep ventilation openings clear of obstruction.
Compliance with national gas regulations shall be observed.
• A warning that the appliance shall be stored in a well-ventilated area where the room size

months.
5.
When the unit is checked for leaks, proper record-keeping of all checks is strongly recommended.
CAUTION
CAUTION
CAUTION
This symbol shows that a service personnel should be handling this
equipment with reference to the installation manual.
This symbol shows that information is available such as the operating
manual or installation manual.
This symbol shows that this appliance uses a ammable refrigerant. If the
refrigerant is leaked and exposed to an external ignition source, there is a
risk of re.
This symbol shows that the operation manual should be read carefully.

Safety Precautions
WARNING
•Securely install the indoor unit on a
structure that can sustain its weight. If the
structure is too weak, the unit may fall and
cause personal injury, unit and property
damage, or death.
• DO NOT install the indoor unit in a
bathroom or laundry room as excessive
moisture can short the unit and corrode the
wiring.
CAUTION
•Install the indoor and outdoor units, cables,
and wires at least 1m (3.2’) from televisions
and radios to prevent static or image
distortion. Depending on the appliances,
a 1m (3.2’) distance may not be sucient.
•If the indoor unit is installed on metal,
it must be electrically grounded.
