Read Safety Precautions Before Operation and Installation
The seriousness of potential damage or injuries is classified as either a WARNING or CAUTION.
Incorrect installation due to ignoring instructions can cause serious damage or injury.
WARNING
WARNINGS FOR PRODUCT USE
•
If an abnormal situation arises (like a burning smell), immediately turn o the unit and disconnect
the power. Call your dealer for instructions to avoid electric shock, re or injury.
•
Do not
insert fingers, rods or other objects into the air inlet or outlet. This may cause injury, since
the fan may be rotating at high speeds.
•
Do not
use flammable sprays such as hair spray, lacquer or paint near the unit. This may cause
fire or combustion.
•
Do not
operate the air conditioner in places near or around combustible gases. Emitted gas may
collect around the unit and cause explosion.
•
Do not
•
•
Do not
expose your body directly to cool air for a prolonged period of time.
•
•
If the air conditioner is used together with burners or other heating devices, thoroughly ventilate
the room to avoid oxygen deficiency.
Safety Precautions
Do not
allow children to play with the air conditioner. Children must be supervised around the
unit at all times.
operate your air conditioner in a wet room such as a bathroom or laundry room. Too
much exposure to water can cause electrical components to short circuit.
In certain functional environments, such as kitchens, server rooms, etc., the use of specially
designed air-conditioning units is highly recommended.
WARNING

CLEANING AND MAINTENANCE WARNINGS
CAUTION
• Turn o the air conditioner and disconnect the power if you are not going to use it for a long time.
• Turn o and unplug the unit during storms.
• Make sure that water condensation can drain unhindered from the unit.
•Do not operate the air conditioner with wet hands. This may cause electric shock.
•Do not use device for any other purpose than its intended use.
•Do not climb onto or place objects on top of the outdoor unit.
•Do not allow the air conditioner to operate for long periods of time with doors or windows open,
or if the humidity is very high.
ELECTRICAL WARNINGS
• Only use the specified power cord. If the power cord is damaged, it must be replaced by the
manufacturer , its service agent or similarly qualied persons in order to avoid a hazard.
• Keep power plug clean. Remove any dust or grime that accumulates on or around the plug. Dirty
plugs can cause re or electric shock.
•
•
•
•
•
•
•
Do not pull power cord to unplug unit. Hold the plug firmly and pull it from the outlet. Pulling
directly on the cord can damage it, which can lead to fire or electric shock.
Do not modify the length of the power supply cord or use an extension cord to power the unit.
Do not share the electrical outlet with other appliances. Improper or insucient power supply
can cause re or electrical shock.
If connecting power to xed wiring, 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.
For all electrical work, follow all local and national wiring standards, regulations, and the
Installation Manual. Connect cables tightly, and clamp them securely to prevent external forces
from damaging the terminal. Improper electrical connections can overheat and cause re, and may
also cause shock.
All electrical connections must be made according to the Electrical Connection
Diagram located on the panels of the indoor and outdoor units.
All wiring must be properly arranged to ensure that the control board cover can close properly. If
the control board cover is not closed properly, it can lead to corrosion and cause the connection
points on the terminal to heat up, catch re, or cause electrical shock.
The product must be properly grounded at the time of installation, or electrical shock may occur.
TAKE NOTE OF FUSE SPECIFICATIONS
The air conditioner’s circuit board (PCB) is designed with a fuse to provide overcurrent protection.
The specifications of the fuse are printed on the circuit board ,such as :
T5A/250VAC, T10A/250VAC, etc.
T20A/250VAC(<=24000Btu/h units), T30A/250VAC(>24000Btu/h units)
NOTE: For the units with R-32 refrigerant , only the blast-proof ceramic fuse can be used.
Safety
Precautions
 Page 5
•Do not
clean the air conditioner with combustible cleaning agents. Combustible cleaning agents
can cause re or deformation.
• Turn o the device and disconnect the power before cleaning. Failure to do so can cause
electrical shock.
•Do not
clean the air conditioner with excessive amounts of water.

WARNINGS FOR PRODUCT INSTALLATION
1. Installation must be performed by an authorized dealer or specialist. Defective installation can
cause water leakage, electrical shock, or fire.
2. Installation must be performed according to the installation instructions. Improper installation
can cause water leakage, electrical shock, or fire.
3. Contact an authorized service technician for repair or maintenance of this unit. This appliance
shall be installed in accordance with national wiring regulations.

cause water damage to your home and property.
For units that have an auxiliary electric heater, do not install the unit within 1 meter of any
combustible materials.
Do not install the unit in a location that may be exposed to combustible gas leaks. If
combustible
gas accumulates around the unit, itmay cause re.
Do not turn on the power until all work has been completed.
When moving or relocating the air conditioner, consult experienced service technicians for
disconnection and reinstallation of the unit.

installation" and "outdoor unit installation" sections .
Note about Fluorinated Gasses
1.
This air-conditioning unit contains fluorinated greenhouse gasses. For specic information on the
type of gas and the amount, please refer to the relevant label on the unit itself or
the
“Owner's Manual - Product Fiche ”in the packaging of the outdoor unit. (European
Union products only)
.
2. Installation, service, maintenance and repair of this unit must be performed by a certified
technician.
3. Product uninstallation and recycling must be performed by a certified technician.
4. For equipment that contains uorinated greenhouse gases in quantities of 5 tonnes of CO2
equivalent or more, but of less than 50 tonnes of CO2equivalent, If the system has a leak-
detection system installed, it must be checked for leaks at least every 24 months.

Louver Angle Memory Function
(some models)
Some models are designed with a louver angle
memory function. When the unit restarts after a
power failure, the angle of the horizontal louvers
will automatically return to the previous position.
The angle of the horizontal louver should not be
set too small as condensation may form and drip
into the machine. To reset the louver, press the
manual button, which will reset the horizontal
louver settings.

(some models)
Other features
Default Setting
When the air conditioner restarts after a power
failure, it will default to the factory settings
(AUTO mode, AUTO fan, 24°C). This may cause
inconsistencies on the remote control and
unit panel. Use your remote control to update
the status.
Auto-Restart (some models)
In case of power failure, the system will
immediately stop. When power returns, the
Operation light on the indoor unit will flash. To
restart the unit, press the ON/OFF button on
the remote control. If the system has an auto
restart function, the unit will restart using the
same settings.
Three-minute protection feature
(some models)
A protection feature prevents the air
conditioner from being activated for
approximately 3 minutes when it restarts
immediately after operation.
