Safety Precautions
WARNING
CAUTION
Read Safety Precautions Before Installation
Incorrect installation due to ignoring instructions can cause serious damage or injury.
The seriousness of potential damage or injuries is classied as either a WARNING or CAUTION.
Failure to observe a warning may result in death. The appliance must
be installed in accordance with national regulations.
Failure to observe a caution may result in injury or equipment damage
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.
• Only trained and certied technidans should install, repair and service this air conditioning
unit.
Improper installation may result in electrical shock, short circuit, leaks, re or other damage to the
equipment and personal property.
• Strictly follow the installation instruct ions set forth in this manual.
Improper installation may result in electrical shock, short circuit, leaks, re or other damage to the
equipment.
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 accor-
dance with the wiring rules.
• Before you install the unit, consider strong winds, typhoons and earthquakes that might aect 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. Refriger-
ant is both toxic and ammable and poses a serious health and safety risk.
• 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.

WARNING
• The appliance shall be stored in a room without continuously operating ignition sources (for exam-
ple: 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.
• Compliance with national gas regulations shall be observed.
• Keep ventilation openings clear of obstruction.
• A warning that the appliance shall be stored in a well-ventilated area where the room size corre-
sponds to the room area as specied for operation.
• Any person who is involved with working on or breaking into a refrigerant circuit should hold a
current valid certicate from an industry-accredited assessment authority, which authorises their
competence to handle refrigerants safely in accordance with an industry recognised assessment
specication.
• 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 supervi-
sion 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 specied for operation.
• Appliance shall be stored in a room without continuously operating open ames (for example an
operating gas appliance) and ignition sources (for example an operating electric heater).
• Appliance shall be installed, operated and stored in a room with a oor area larger than X m2, instal-
lation 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.

1. This air-conditioning unit contains uorinated gasses. For specic information on the type of gas
and the amount, please refer to the relevant label on the unit itself.
2. Installation, service, maintenance and repair of this unit must be performed by a certied techni-
cian.
3. Product uninstallation and recycling must be performed by a certied technician.
4. If the system has a leak-detection system installed, it must be checked for leaks at least every 12
months.
5. When the unit is checked for leaks, proper record-keeping of all checks is strongly recommended.
Explanation of symbols displayed on the indoor unit or outdoor unia (applicable to
the unit adoptsR32/R290 Refrigerant only):
WARNING
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.
CAUTION This symbol shows that the operation manual should be read carefully.
CAUTION This symbol shows that a service personnel should be handling this
equipment with reference to the installation manual.

Indoor Unit Installation
Indoor Unit Parts
Safety Precautions
Fig. 4.1
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 person-
al 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 1 m (3.2’) from televisions
and radios to prevent static or image distor-
tion. Depending on the appliances, a 1 m
(3.2’) distance may not be sucient.
• If the indoor unit is installed on metal, it must
be electrically grounded.

Indoor Unit Installation Instructions
NOTE: Panel installation should be performed
after piping and wiring have been completed.
RECOMMENDED DISTANCES BETWEEN THE INDOOR UNIT
The distance between the mounted indoor unit should meet the specications illlustrated in
the following diagram. (See Fig. 4.2)
Step 1:Select installation location
The indoor unit should be installed in a loca-
tion that meets the following requirements:
☑ Enough room exists for installation and
maintenance.
☑ Enough room exists for the connecting the
pipe and drainpipe.
☑ The ceiling is horizontal and its structure
can sustain the weight of the indoor unit.
☑ The air inlet and outlet are not blocked.
☑ The airow can ll the entire room.
☑ There is no direct radiation from heaters.
CAUTION
DO NOT install the unit in the following
locations:
Areas with oil drilling or fracking
Coastal areas with high salt content in the air
Areas with caustic gases in the air, such as hot
springs
Areas that experience power uctuations,
such as factories
Enclosed spaces, such as cabinets
Kitchens that use natural gas
Areas with strong electromagnetic waves
Areas that store ammable materials or gas
