vacuum or by hand washing.
Open the panel and put the Air filter out.

position and close the front panel.
Clean the Air filter with a vacuum cleaner or
soft brush. If dust is too heavy, rinse it with
running water.
Dry the Air filter in a ventilated area.
Clea ning and Maintenance
CAUTION
• Do not scrub the air filter with a brush or other cleaning utensil.
This may damage the filter.
• Do not expose the air filter to direct sunlight when drying it.
NOTE
• Clean the air filter every 2 weeks. Cleaning term may vary depending on the usage and
environmental conditions.
• If the air filter dries in a humid area, it may produce offensive odours. Clean it again and dry
it in a well-ventilated area.

If the air conditioner operates abnormally, refer to the following
chart to save time and unnecessary expenses.
Problem
Solution
The air
conditioner does
not work at all.
• Check the power status, then operate the air
conditioner again.
• Switch on the circuit breaker, plug in the power
cord, then operate the air conditioner again.
• Make sure that the isolator is turned on.
• Check whether the Timed off function is
running. Operate the air conditioner again by
pressing the Power button.
I cannot change
the temperature.

Cool/Warm air
does not come
out the air
conditioner or
performance is
reduced.
30 English
Solution
• Check whether the set temperature is higher in
the Cool mode or lower in the Heat mode than
the current temperature. Press the Temperature
button on the remote control to change the set
temperature.
• Check whether the air filter is blocked with
dirt. If the air filter is blocked, the cooling and
heating performance may decrease. Remove dirt
regularly.
• Check if the outdoor unit is covered or installed
near the obstacle. Take the cover off and take
the obstacle away. When clearing the obstacle
(e.g. snow or ice), use suitable tools so as to be
careful not to damage the product nor injure
yourself during this process.
• Check whether the air conditioner is running
the defrost function. When ice forms in winter
or the outdoor temperature is too low, the
air conditioner runs the defrost function
automatically. While this function is running, the
indoor fan stops and warm air does not come
out.
• Check whether doors or windows are open. This
may cause poor cooling or heating performance.
Close the doors and windows.
• Check whether the air conditioner is turned
on immediately after the cooling or heating
operation stops. In this case, only the fan runs to
protect the outdoor unit compressor.
• Check whether the pipe length is too long. When
the pipe length exceeds the maximum pipe
length, the cooling and heating performance
may decrease.
Problem
Solution
I cannot change
the fan speed.
• When the Auto, Dry, or Fast mode is running
or the good'sleep function is running in the
Cool mode, the air conditioner controls the fan
speed automatically and you cannot change
the fan speed.
The remote
control does not
work.
• Replace the batteries in the remote control
with new ones.
• Make sure that nothing is blocking the remote
control sensor.
• Check whether there are strong lighting
apparatus near the air conditioner. Strong light
which comes from fluorescent bulbs or neon
signs may interrupt the electric waves.
The Timed on/off
function does not
work.
• Check whether you pressed the SET button on
the remote control after setting the time.
The indicator
blinks
continuously.
• Press the Power button to turn off the air
conditioner or disconnect the power plug. If the
indicator is still blinking, contact the service
centre.

Clea ning and Maintenance
I cannot change
the air flow
direction.
• Check whether the good'sleep function is
running. While this function is running, you
cannot control the air flow direction. (But you
can control the air flow direction if this function
is running in the Heat mode.)

Clea ning and Maintenance
Odours permeate
in the room
during operation.
• Check whether the air conditioner is running
in a smoky area. Ventilate the room or operate
the air conditioner in the Fan mode for 3 to 4
hours. (There are no components used in the
air conditioner that emit a strong odour.)
• Check whether the drains are clean. Clean them
regularly.
An error is
indicated.
• If the indoor unit indicator blinks, contact the
nearest service centre. Be sure to pass the
error code to the service centre.
Noise is
generated.
• When refrigerant flow changes, noise may be
generated, depending on the status of the air
conditioner. This is a normal operation.
'Excessive Noise
is Generated'
and ‘Reduced
Performance'
• If excessive/irregular noise is generated in
conjunction with reduced product performance,
please refer to your service engineer to ensure
the product is operating correctly.
Smoke is
generated from
the outdoor unit.
• If may not be a fire but it can be a steam
generated from the outdoor heat exchanger
while the defrost function is running in the
Heat mode in winter.
Water drops
from the pipe
connections of
the outdoor unit.
• Condensation may develop when the ambient
temperature changes excessively. This is a
normal operation.
To perform its antimicrobial function this product has been treated
with the biocide substance Silver zinc zeolite.
