Room humidity should be lower than 90%.
Otherwise, it is possible for air conditioner to dew
at air conditioner surface and even drop water af-
ter running for so much time. But this is normal.
Water pipe
The electric components will be damaged when the voltage is too high.
If the voltage is too low, the compressor will vibrate violently to dam-
age the refrigerant system and easily cause the compressor and elec-
tric components not work.
The ground must be connected.
Special socket must be used. Furthermore, the socket and wiring
must conform to the wiring regulations. And the earthing method
must be reliable.
In fixed circuit, there must be electricity leakage protection switch
of enough power capacity and air switch with enough space.

In fixed circuit, there must be electricity leakage protection switch and leakage current
is less than 30mA.
Air switch (thermal-magnetic breaker) should be installed in the circuit and its capacity is
10A (12K) / 16A (18K、24K).
Connecting method between air conditioners and power cord and interconnecting method
of each individual element with one another should accord with wiring diagram on the unit.

Operation Tips
Operation for comfort and economy
Do not overcool the room
temperature. This is not good
for health and wastes electricity.
Keep blind or curtains closed.
Do not let sunshine enter the
room directly when the air con-
ditioner is in operation.
Keep the room temp. uniform.
Adjust the vertical and horizon-
tal airflow direction to ensure a
uniform temperature in the room.
Air can’t be discharged to the di-
rection of air-in.
Make sure that the doors and win-
dows are tightly closed. Avoid open-
ing doors and windows as much as
possible to keep air conditioning in the
room.
Clean the air filter regularly.
Blockages in the air filter re-
duce dehumidifying effects.
Clean the air filter at least once
every two weeks.
Ventilate the room occasionally.
Since windows are kept closed, it
is a good idea to open them and
ventilate the room now and then.
When starting the unit, curtains or
windows should be closed to pre-
vent the heat/cool leakage.

for other purposes except for
cooling the room.
Do not use the air conditioner
for other purposes such as
drying clothes, preserving
foods, or cultivating
vegetables.
Do not block the air intake and
outlet vents

mance and irregular operation.
Do not insert sticks or other
objects into these vents as it is
dangerous to touch the electric
components and the fan.
Always wait at least 3 minutes before switching the
air conditioner on again after you have switched it
off during cooling or heating.
Always wait
at least 3 minutes
Do not pull out the power cord.
Damage to the cord may result
in serious electric shocks.
s
plastic parts will melt if exposed to
excessive heat.
Avoid exposing the body directly to
a continuous unidirectional air flow
for long periods.
This is not recommended for health
reason.
Select the most appropriate
temperature.
Pay attention to adjust the tempera-
ture to suit the conditions.
Rooms occupied by infants,the
elderly, or the sick should be kept at
an appropriate temperature.
