Wind direction adjusting

1.Horizontal wind direction adjusting

Use hands to move the vane and change the
horizontal wind direction.

Note:

Adjust the horizontal wind direction before the
air-conditioner starts. Don t insert your finger
into air-out window when the air-conditioner is operating.

2.Vertical wind direction adjusting

Refer to Remote Controller Usage Instruction for how to adjust vertical wind direction
through adjusting the horizontal airflow vane by remote controller.

Note

Adjust the vertical wind direction by remote controller. When you adjust the horizontal
airflow vane by hand, the machine may cause problem.

When the air-conditioner stops, the horizontal wind vane will close the wind outlet of air­conditioner.

Please read this instruction before using the air-conditionerand follow
the instr ction. Otherwise, it may cause damage to the air-conditioner or
to the other person s safety and property.

Checking before usage

Set the suitable temperature, especially when there are old people, children and patients
in the room.

In the case the air-conditioner occurs closing down or gash due to the severe interference
from outer environments such as auto and mobile phone etc.,please take off the plug and
then plug in after several seconds to restart the air-conditioner.

Installation should always be carried out by specialist. The customers should not install
the air-conditioner by themselves, Otherwise, it may cause damage to the air-conditioner or
to the other person s safety and property.

In order to properly use the air-conditioner ,please follow the Working condition in the
instructions, otherwise, it may activate the inside protection, or lead to weeping, or
decrease the cooling/heating efficiency.

Note

Safety rules

Generally ,keep the temperature difference between the inside and outside

within 5 .

Methods of resolution

The normal protections of the air-conditioner

1.Compressor protection

The compressor will not restart within 3 minutes after stop operating

the heating operation just starts frost dissolving operation
operating under low temperature

Cold wind prevention (heat pump type )

Non-air-conditioner trouble

In the heating mode, the indoor unit won t send wind or operate in low wind ,if the heat
exchanger of indoor unit has not reached the stipulated temperature in the following
three states, so as to prevent the cold wind.

,

Frost dissolving operation (hot pump type )

The fan of the indoor and outdoor unit will stop under frost dissolving operation.
The time for frost dissolving varies in range of 4 to 10 minutes according to the out-

door temperature and the frost condition.

It is normal phenomenon that there may be steam coming out from the outdoor unit

during the frost dissolving operation.

When the temperature is low and humidity is high outdoors, the heat exchanger of
outdoor unit may frost, which may decrease the heating capacity. In such case, the air­conditioner will stop the heating operation and convert to automatic frost dissolving,
and then resume heating after the frost dissolving finishes.

,

8

When the outdoor temperature falls, the heating capacity decrease accordingly because the
heat absorbed from outdoors decreases (See the figure at the right).At the same time, the
temperature difference between indoors and outdoors is enlarged, so that the heating load
increase accordingly. If the air-conditioner can not reach a satisfactory effect, it is
recommended that other heating devices be used together.

2.White steam comes out from the indoor unit

During the cooling operation ,under high relative humidity indoors, white steam may come
out due to the high humidity and temperature difference of air inlet and outlet.

The air-conditioner convert to heating operation after the frost dissolving, the moisture
(due to frost dissolving) is discharged in form of steam.

3.High noise during operation

4.Dust is blown out from the indoor unit

5.The peculiar smell emanates from indoor unit

6.Cooling /Heating (not for cold wind type) operation converts to only wind mode.

7.If you select the cooling operation in a relatively damp environment (relative humidity
is higher than 80%),dew may be formed over the surface of indoor unit and drop. In such
a case, please adjust the vertical wind vanes to its maximum ventilation position(i.e.,close
to the position normal to the horizontal direction)and choose to improve the dew
phenomenon.

high

When the air-conditioner is used the first time after being left unused for a long time, the
dust inside the indoor unit will be blown out.

The s ell which absorbed from room, furniture, clothing or cigarette emanates during the
air-conditioner is operating.

m

When the indoor unit reaches the stip lated temperature, the air-conditioner will stop the
operation of compressor and convert to only wind mode. The compressor will restart
cooling or heating after the room temperature rise or drop to a certain degree.

u

When the compressor is operating or just stops operation, fizzle may be heard because of
the refrigerant flow or stop flowing.

After the air-conditioner operates or stops for a while, crackle from the naturel expansion
and contraction of the plastic components may be heard because of temperature variation.
When the air-conditioner is energized for the first time, sound from friction may be heard
because of the rotating of wind wave.

8.Heating operation (heat pump type )

During the heating operation ,the heat pump of
air-conditioner operates with the principle of
absorbing heat outdoor and release heat indoor.

2.Use vacuum cleaners or water to clean the air filter, then dry it in a dark and cool place.

3.Insert the upside of air filter into the machine until being entirely fixed, close the front
panel and tighten it.

After the air-conditioner is left unused for a long period ,check the inlet and outlet of
indoor and outdoor unit for any possible blockage, if any, please clean it.
Before the air-conditioner will be left unused for a long period, please make the
following preparation.

For the purpose of safety, please turn off the air-conditioner and cut off the power supply
before cleaning.

If the air filter is cover by dust, the cooling effect will be decreased. Please regularly
clean the air filter.

1.Raise up the front panel of indoor unit until it suddenly stops; then raise up the protruded
part of air filter and pull it out downwards.

Don t use dedusting products by chemicals or place close to the machine.

3.The panel of indoor machine may be taken off. Dry it after cleaning with wet cloth.

2.If the indoor unit is very dirty, please wipe with wet cloth dipped by cold water.

Don t use harsh chemicals or abrasive cleaners on any part of the unit.

1.Wipe the indoor unit with dry cloth .

Installation

The machine must be installed correctly by according to the licenced electrician

Guide of customer

Installation position

Items of attention

The customer should have a qualified power supply coincident with the tag of the air
conditioner, its voltage should be in the range of 90-110% of its rated voltage.

The power supply circuit should have leakage protector and air switch of which the
capacity should be more than 1.5 times of the maximum current.

Must use special circuit and efficient grounding socket matching with the plug of air­conditioner.

The wiring must be done by qualified electrician according to the electrical safety
requirements.

The air-conditioner must be well grou ded, the switch of the main power of air­conditioner must be reliably grounded.

n

Don t pull the power supply wire.

Fix the machine firmly, otherwise it will produce noise and vibration.

Install the outdoor unit where it will not disturb your neighbor.
