SAFETY PRECAUTION
•Do not reconstruct the unit.
Water leakage, fault, short circuit or fire may occur if you reconstruct the unit by
yourself.
•Please ask your sales agent or qualified technician for the installation of your unit.
Water leakage, short circuit or fire may occur if you install the unit by yourself.
•Please use earth line.
Do not place the earth line near water or gas pipes, lightning-conductor, or the
earth line of telephone. Improper installation of earth line may cause electric
shock or fire.
•Be sure to use the specified piping set for R410A. Otherwise, this may result in
broken copper pipes or faults.
•A circuit breaker should be installed depending on the mounting site of the unit.
Without a circuit breaker, the danger of electric shock exists.
•Do not install the unit near a location where there is flammable gas. The outdoor
unit may catch fire if flammable gas leaks around it. Piping shall be suitable
supported with a maximum spacing of 1m between the supports.
•Please ensure smooth flow of water when installing the drain hose.
•Make sure that a single phase 220V power source is used.
The use of other power sources may cause electrical components to overheat
and lead to fire.

•Do not place plants directly under the airflow as it is bad for the plants.
•Do not direct the cool air coming out from the air-conditioner panel to face
household heating apparatus as this may affect the working of apparatus such
as the electric kettle, oven etc.
•The product shall be operated under the manufacturer specification and not
for any other intended use.
PRECAUTIONS DURING OPERATION
CAUTION
•Do not attempt to operate the unit with wet hands, this could cause fatal
accident.
•When operating the unit with burning equipments, regularly ventilate
the room to avoid oxygen insufficiency.
•Please ensure that outdoor mounting frame is always stable, firm and without
defect. If not, the outdoor unit may collapse and cause danger.
•Do not wash the unit with water or place a water container such as a vase on
the indoor unit.
Electrical leakage could be present and cause electric shock.
•Be sure to stop the operation by using the remote controller and turn off the
circuit breaker during cleaning, the high-speed fan inside the unit may cause
danger.
•Turn off the circuit breaker if the unit is not be operated for a long period.
•Do not climb on the outdoor unit or put objects on it.
•When operating the unit with the door and windows opened, (the room
humidity is always above 80%) and with the air deflector facing down or moving
automatically for a long period of time, water will condense on the air deflector
and drips down occasionally. This will wet your furniture. Therefore, do not
operate under such condition for a long time.
•If the amount of heat in the room is above the cooling or heating capability of
the unit (for example: more people entering the room, using heating equipments
and etc.), the preset room temperature cannot be achieved.
•Indoor unit cleaning must be performed by authorized personnel only. Consult

FILTER CLEANING UNIT OPERATION CHECK
Make sure the power plug is firmly plugged into the power outlet.
WARNING
•Be sure to use the power outlet exclusively for
air conditioner
Use of other power outlet may cause heat, which
could result in fire.
•Make sure that dust is not deposited on the
power plug and be sure to plug in until the blades
of the plug are fully inserted to avoid unstable
plug-in and dust from being accumulated
Use of air conditioner with dusty power plug or
improper power connection could result in electrical
shock or fire.
CAUTION

Performing operation check after the power is turned on.
Perform the filter cleaning unit operation check
•After the power is turned on (after the power plug is inserted into the power
outlet or after the circuit breaker is switched on after power failure), the
cleaning unit makes one cycle of back and forth movement.
•At this time, the (CLEAN) indicator is lit.
•One cycle of operation check will take approximately 5 minutes.
•During the operation check, the unit performs “Fan” operation while the movable
panel and horizontal air deflector remain closed.
•If the (CLEAN) indicator blinks (lit for 4 seconds/off 1 second) after the
operation check, refer to “Troubleshooting” on page 44.

Example: Cooling
With the infrared sensor, the air conditioner can detect the activity level in a room and adjust the temperature
and humidity automatically, thus achieving the purpose of energy saving.
Press the INFRARED SENSOR button.
The infrared sensor automatically adjusts the
indoor temperature and humidity according to
the activity level in the room. However, the
temperature e and humidity specified by the
remote controller remain unchanged.

•The energy saving effect can be achieved only after the energy-saving temperature control function keeps
working
for more than 2 hours.
In the energy-saving temperature-control mode, the energy consumption saved by the air conditioner varies with
the activity level.

The infrared sensor detects changes to the infrared generated by human bodies. Therefore, the accuracy
of infrared
sensor may be affected negatively in the following cases:
·
·
The activity level is very low (reading, watching TV, etc.) or human bodies are blocked by a screen, cabinet, or glass board.
·
·
The indoor temperature is very high and exceeds or approaches the human body temperature (when the refrigeration
just begins).
·
·
The person wears thick clothes and turns his/her back to the air conditioner.
·
·
Curtains or plant leaves swing due to pet movement or airflow.

•
The tracing function (Page 20) can further reduce the energy consumption.
After detecting that the person leaves the room for 30 minutes, the air conditioner turns to the energy-saving modes
according to the settings in the remote controller as shown in the right table, but the preset temperature and humidity
in the remote controller remain unchanged.
When the air conditioner works in powerful operation, setting the energy-saving mode will cancel the powerful operation.

DYNAMIC AIR DEFLECTION FUNCTION (TRACING/EVASION)
The infrared sensor can detect the position of people and automatically change the airflow direction.
Press the AUTO AIR DEFLECTION button to switch the air deflection
mode.
■How to change the detection speed of the sensor of the dynamic air deflection (tracing/evasion) function:
·There are 2 detection speeds: “Standard” (by intervals of 15"–3') and “Slow” (by intervals of 1'–10').
·The remote controller is set to the standard speed by default.
·When the detection speed of the sensor is too high, set the detection speed to “Slow”
(when people and pets in the room behave frequently, resulting in frequent changes to the airflow direction).
·After the dynamic air deflection mode is set, the sensor usually works once every 15 seconds to 3 minutes to
detect the position of the person and adjusts the airflow direction accordingly.
(The airflow direction does not change with the movement of human body immediately.)
·If the dynamic air deflection mode fails to achieve the desired effect, adjust the airflow direction manually.
·When the machine works in cooling, dehumidifying, or dry cool operation after the dynamic air deflection is set,
if the indoor humidity/temperature is very high, the left/right/upper/lower air deflectors may change their angles
to prevent drop of condensed water. After the temperature falls, the air conditioner returns to the dynamic air
deflection status.

After the running stops, hold down for more than 5 seconds while pressing and holding .
·At this time, the air conditioner beeps for signal receiving.
·Return to the “Standard” mode by repeating the above procedure (until the air conditioner beeps for
signal receiving).
In addition to “Standard” and “Slow” modes, you can also fine tune the detection speed of the sensor.
