Open the door and window and keep good ventilation in the room to avoid oxygen deficit

when the gas/oil supplied heating equipment is used.
Volatile liquid, such as diluent or gas will damage the unit appearance. Only use soft cloth

with a little neutral detergent to clean the outer casing of unit.
Install the air conditioner in a solid place that can withstand its weight. Fully consider the

influence of strong winds, typhoons and earthquakes and reinforced installation. Improper
installation will cause the air conditioning unit to fall and then cause injury.
Please use the electric wire with specified specifications. Electrical installation work must

comply with local laws and regulations. Insufficient capacity or improper electrical operation
can cause electric shock or fire.
All electric wires must be confirmed to be connected well so that the wiring terminals and

electrical wires are not pulled by external force. Improper installation may cause fire.
After connecting the power cord, please fix the electric box cover properly in order to avoid

accident.
After confirming that the unit's power is off, you can touch the electrical components of the

unit, otherwise it will cause electric shock.
Do not modify the unit protection settings. If a pressure switch, end switch or other protective

device is short-circuited and forced to operate, it may cause a fire or explosion.
When installing the unit, make sure that the connection pipe is securely connected before

starting up the compressor. If the compressor is started up before the connection of the
connecting pipe is completed and the shut-off valve is opened, mixed air will cause the
system pressure to rise, which may cause compressor bursting accident and injury.
Heat exchanger fins are sharp. You may be injured if used it incorrectly. Please wear the

gloves to avoid injury.
Do not directly touch the refrigerant pipes during the operation and when the operation is

finished just now, including refrigerant pipes, compressors, and other refrigerant circulation
pipes. These pipes are hot and cold. It will scald and frostbite if directly contacts them. To
avoid injury, please wait until the pipes reach to normal temperature. Please wear gloves
when you must touch it.
Improper installation of drain pipes can result in water leakage and poor function.

R410A is a mixture. The refrigerant must be filled from the liquid pipe. If the refrigerant is filled

from the gas pipe, the composition of the refrigerant will change and the system can't operate
normally.
Take adequate measures to prevent small animals from making nests in the unit. Once small

animals touch electrical components, it may cause malfunction or fire hazard. Remind
customers to clean around the unit.
The installed indoor unit, outdoor unit, power cord and connection wire must be at least 1m

away from the TV or radio to avoid image interference or noise. If the radio wave is strong,
sometimes even if the distance is more than 1 m, it is not enough to avoid interference.
When disassembling the unit, handling refrigerants, oil and other components of the unit, it

must be in accordance with the relevant national/continental regulations.
