•
If connecting power to fixed wiring, an all-pole disconnection device which has at least 3mm
clearances in all poles, and have a leakage current that may exceed 10mA, the residual current
device(RCD) having a rated residual operating current not exceeding 30mA, and disconnection
must be incorporated in the fixed wiring in accordance with the wiring rules.
TAKE NOTE OF FUSE SPECIFICATIONS
The air conditioner’s circuit board (PCB) is designed with a fuse to provide overcurrent protection.
The specifications of the fuse are printed on the circuit board ,such as :
T3.15AL/250VAC, T5AL/250VAC, T3.15A/250VAC, T5A/250VAC, T20A/250VAC, T30A/250VAC,etc.
NOTE: For the units using R32 or R290 refrigerant , only the blast-proof ceramic fuse can be used.

NOTE: Room relative humidity less than 80%. If the air conditioner operates in excess of this
figure, the surface of the air conditioner may attract condensation. Please sets the vertical air
flow louver to its maximum angle (vertically to the floor), and set HIGH fan mode.
To further optimize the performance of your unit, do the following:
•
Keep doors and windows closed.
•
Limit energy usage by using TIMER ON and TIMER OFF functions.
Do not block air inlets or outlets.
•
Regularly inspect and clean air filters.

Other Features
• Auto-Restart(some units)
If the unit loses power, it will automatically
restart with the prior settings once power has
been restored.
• Anti-mildew (some units)
When turning off the unit from COOL, AUTO
(COOL), or DRY modes, the air conditioner will
continue operate at very low power to dry up
condensed water and prevent mildew growth.
• Wireless Control (some units)
Wireless control allows you to control your air
conditioner using your mobile phone and a
wireless connection.
For the USB device access, replacement,
maintenance operations must be carried
out by professional staff.
• Louver Angle Memory(some units)
When turning on your unit, the louver will
automatically resume its former angle.
• Active Clean function(some units)
-- The Active Clean Technology washes away
dust, mold, and grease that may cause odors
when it adheres to the heat exchanger by
automatically freezing and then rapidly thawing
the frost. A “pi-pi” sound will be heard.
The Active clean operation is used to produce
more condensed water to improve the cleaning
effect, and the cold air will blow out. After
cleaning, the internal wind wheel then keeps
operating with hot air to blow-dry the evaporator,
thus preventing the growth of mold and keeping
the inside clean.
-- When this function is turned on, the indoor
unit display window appears “CL ” , after 20
to 45 minutes, the unit will turn off automatically
and cancel Active Clean function.
This feature avoids direct air flow blowing on
the body and make you feel indulging in
silky coolness.

(some units)
The indoor unit will automatically display
“EL0C”or flash LEDS (model dependent )
when it detects refrigerant leakage.
Sleep Operation

The SLEEP function is used to decrease
energy use while you sleep (and don’t
need the same temperature settings to
stay comfortable). This function can only
be activated via remote control. And the
Sleep function is not available in FAN or

Press the SLEEP button when you are
ready to go to sleep. When in COOL mode,
the unit will increase the temperature
by 1°C (2°F) after 1 hour, and will increase
an additional 1°C (2°F) after another hour.
When in HEAT mode, the unit will decrease
the temperature by 1°C (2°F) after 1 hour,
and will decrease an additional 1°C (2°F)

The horizontal angle of the airflow must be set
manually. Grip the deflector rod (See Fig.B)
and manually adjust it to your preferred direction.
For some units, the horizontal angle of the airflow
can be set by remote control. please refer to the
Remote Control Manual.
While the unit is on, use the SWING/DIRECT
button on remote control to set the direction
(vertical angle) of airflow. Please refer to the
Remote Control Manual for details.
NOTE ON LOUVER ANGLES
When using COOL or DRY mode, do not set
louver at too vertical an angle for long periods
of time. This can cause water to condense on
the louver blade, which will drop on your floor
or furnishings.
When using COOL or HEAT mode, setting the
louver at too vertical an angle can reduce the
performance of the unit due to restricted air
flow.
