Install the unit securely; otherwise it will cause abnormal
noises and vibration due to poor installation. If necessary,
take measures to reinforce the unit's stability.
Install the unit at a place where the running noise and the
exhaust air do not affect neighbours.
If the air conditioner makes abnormal sounds during
operation, contact your local distributor.
If you are moving or wish to move the air conditioner, contact
your local distributor.
Check whether the grounding cable is broken and disconnected.
Turn on the power switch 12 hours before operation.
Check the following items before asking a professional to provide
maintenance or repair.
Check the following items before asking a professional to provide
maintenance or repair.
1. 3-minute protection
The ODU cannot operate for about 3 minutes after the ODU is
turned off and on again immediately when the power switch is turned
on, because the compressor cannot start within 3 minutes after
shutdown. This is the self-protection function of the machine.
1. The IDU emits white mist
2. Anti-cold breeze protection
The following situations may occur in heating mode (including
heating in automatic mode) to prevent the blowing of cold air: the
indoor heat exchanger does not reach a certain temperature, the
indoor fan temporarily stops running, or runs in Breeze mode. When
the indoor fan stops running, the anti-cold/air supply indicator is on.
CAUTION
In the Fan mode, the operating indicator is on, while the
anti-cold/air supply indicator
is off.

NOTE
For air conditioners with electric heaters, the electric heater is
secured between the wind turbine and the heat exchanger of
the IDUs using screws. The user is prohibited from
disassembling and repairing the part. Otherwise, a fire or other
dangers may occur.
The heating operation has just started.
The unit runs in defrosting mode.
The unit runs in heating mode when the outdoor ambient
temperature is very low.
3. When the protection device works, the operation stops, as follows:
4. Defrosting
When the outdoor temperature is low and the humidity is high, the
IDU’s heat exchanger may be frosted, which may reduce the heating
capacity of the air conditioner. In this case, the air conditioner will
stop heating, enter automatic defrosting mode, and return to heating
mode after defrosting has been completed.
When the starting conditions are not met and the unit is started
forcibly, the indicator is on.
The unit runs in the cooling mode.
The air inlet or outlet of the ODU is blocked; strong winds blow to
the air outlet of the ODU.
The unit runs in the heating mode.
The air inlet or outlet of the IDU is blocked.
During the defrosting, the outdoor fan stops running and the
indoor fan runs based on the anti-cold breeze protection
function.
The defrosting operation time varies depending on the outdoor
temperature and the degree of frosting. It generally takes 2 to 10
minutes.
During the defrosting process, the ODU may emit steam due to
the rapid defrosting, which is a normal phenomenon.
In an environment where the indoor relative humidity is too high,
when the IDU runs in the cooling mode, white mist may appear
due to the humidity and the temperature difference between the
air inlet and outlet.
When the air conditioner is switched to heating mode after the
defrosting operation, the IDU discharges the moisture generated
defrosting as steam.
2. The IDU blows dust
When the air conditioner has not been used for a long time or is
used for the first time, dust that has entered the IDU is blown
out.
3. The IDU emits odour
The IDU absorbs the odours of rooms, furniture or cigarettes and
others, and disperses the odours during operation.
4. When the indoor relative humidity is high, it is normal for
condensation or slight water blowing to occur on the surface of the
air conditioner.
5. The air conditioner makes small noise.
6. The unit is switched from Cool/Heat (unavailable on a cooling-only
unit) mode to the Fan mode.When the IDU reaches the set
temperature, the air conditioner controller automatically stops the
compressor operation and switches to the Fan mode only. When the
room temperature rises (in Cool mode) or falls (in Heat mode) to a
certain extent, the compressor is restarted, the cooling or heating
operation is resumed.
7. In Winter when the outdoor temperature is very low, the heating
effect may be affected.During the heating operation of the cooling
and heating type air conditioner, the air conditioner absorbs heat
from the outdoor air and releases it to heat the indoor air. This is the
heat pump heating principle of the air conditioner. When the heat
pump activates, the ODU blows out cold air and the outdoor
temperature drops. When the outdoor temperature is low, the
heating capacity is affected. It is recommended to use other heating
devices to enhance the heating effect.
When the air conditioner runs in the Auto, Cool, Dry, or Heat
mode, the unit can create a small and continuous hissing sound,
which is caused by the flow of refrigerant between the indoor unit
and the outdoor unit.
A hissing sound may be heard in a short time after the unit stops
operation or during the defrosting operation. The sound is
caused when the refrigerant stops flowing or the flow is changed.
When the air conditioner is in Cool mode (including the Cool
mode in automatic mode) or Dry mode, a small and continuous
rustling sound can be heard, which is caused by the running of
the drain pump.
When the air conditioner has just started running or stopped
running, you may hear a squeaky sound, which is caused due to
the natural expansion or contraction when the temperature of the
plastic parts changes.
Do not install the air conditioner in places with strong winds,
such as seaside, roof or high-rise buildings.
Do not install the air conditioner in places exposed to sulphur
gases as hot springs.
Do not install the air conditioner on a ship or mobile crane.
