Attention
Before installation, check whether all power sources conform to the requirements on the
nameplate and make sure of the power supply safety.
Before use, check and confirm whether the electric wires, drain pipes and tubes are firmly
connected to prevent water leakage, refrigerant leakage, electric shock, fire or other
accidents.
The power supply socket must be equipped with ground wire to ensure the air conditioner
could be effectively grounded through the power socket and avoid electric shocks. Never
connect the ground wire onto the gas pipes, water pipes, lightning rods or phone wires.
Once started, never shut down the air conditioner within 5 minutes’ running, or it will affect
the compressor oil return.
Never let kids operate the air conditioner.
Never operate the air conditioner if your hand is wet.
While cleaning the air conditioner or replacing the air filter, please cut off the power supply at
first.
If idle for long, please cut off the power supply.
Never step on or place any object on the air conditioner.
Power on for leakage test after installation.

1. Safety instructions

1-1 Electrical safety requirements
1) Wiring work must be done by formally qualified electricians.
2) All wiring work must meet the electrical safety specifications.
3) The air conditioner must be well grounded, namely, the air conditioner must have its main switch
reliably grounded.
4) The air conditioner must be provided with separate power supply according with the rated
parameter value.
Please contact our authorized service center for installation. Improper installation may result
in water leakage, electric shocks, fires and other accidents.
Never put sticks or other objects into the air inlet and outlet.
Do use within the required voltage and frequency with protection devices equipped
accordingly. Never use any copper wire to replace the fuse to avoid failures or fires.
The air conditioner shall have its ground wire firmly connected with that of the power source.
While cleaning, never splash water onto the air conditioner, in order to avoid failures or
electric shocks.
Never have the indoor or outdoor unit inlet or outlet blocked to avoid impact on the
performance of the air conditioner and prevent failures.
If idle for long, disconnect the power supply to ensure safety and save energy.
When restarted after a long-term shutdown, do carefully check whether the air conditioner
and its power lines are normal. If the power lines are damaged or need replacing due to other
reasons, please contact our after-sales service staff or authorized repair professionals to
avoid electric shocks, overheating, fires or other accidents.
Never place any water container on the air conditioner to avoid electric shocks due to water
immersion.
After a long-term use, please confirm whether the mounting platform is worn, and if worn, the
air conditioner may fall to cause casualties.
Never operate the switch if your hand is wet to avoid electric shocks.
In time of repair, stop the air conditioner with the power supply cut off, or the high-speed
rotation of the internal wind turbines may lead to injuries.
Never use any other fuse beyond the capacity regulated in this Manual. Never use any iron
or copper wire to avoid failures, fires and other consequences. Do use the special circuit
under the rated voltage for air conditioners.

3-3 Air direction adjustment
According to the characteristics of cold air sinking and hot air rising, please adjust the air-out direction of
the air guide in time of cooling and heating to improve the cooling and heating effects.
Attention
3-3-1 4-way Cassette Type
①In the cooling operation, the air guide should be
kept at horizontal air-out operation.
②In the heating operation, the air guide should be
kept at downward air-out operation.
③When using the panel equipped with automatic swing air guide, press the “Swing” button, and the
outlet air guide will automatically swing to get better cooling and heating effect.

3-4 Optimal operation
Pay attention to the following items to ensure the optimal operation of the system with the specific
operation methods referring to the corresponding contents.
1) Adjust the airflow direction appropriately to avoid directly blowing the persons in the room. In time
of cooling operation, please adjust the air guide to the horizontal air-out state in order to have the
whole room better cooled; and in the heating operation, please adjust the air guide to the downward
air-out state in order to have the room floor better heated.
2) Set the temperature appropriately to obtain a comfortable environment and avoid excessive heat
or cold.
3) In the cooling operation, the curtains or blinds should be used to prevent direct sunlight indoors.
4) Please close the doors and windows to avoid the indoor-outdoor air convection and obtain a better
refrigerating or heating effect.
5) Please well set the predetermined running time via the “Timer” button on the remote controller.
6) Never put any object near the air inlet or outlet. Otherwise, it will reduce the efficiency of the air
conditioner and even have the system stop running.
7) If the air filter screen is blocked, the cooling or heating effect will be worsened, so it needs washing
once every two weeks.
