Please pay attention if unit has some abnormal operation. See cases and explanations below.
In case of refrigerant leakage sensor
Case
Explanation
The unit is operating by itself.
The fan is spinning by itself,
when the unit is turned off.
(The operation light is flashing.)
■ It is because the refrigerant leakage sensor started working:
• In case it makes a beeping sound, there is a risk of refrigerant
leakage. Please ventilate the room and contact your dealer.
• When there is no beeping sound, then there is no refrigerant
leak, or it is still doing detection.
If there is no leak, the fan will turn itself off automatically in a few
minutes.
Sometimes, the refrigerant leakage sensor detects by mistake
substances other than refrigerant, such as insecticides or
hairsprays (only for R32 refrigerant).
It makes a sound.
Continuous beeping, and the
operation light is flashing.
■ It is because the refrigerant leakage sensor started working.
There is a risk of refrigerant leakage, so please ventilate the room,
and contact your dealer (only for R32 refrigerant).
It does not cool / warm up.
When in cooling or heating mode,
it switches to “Strong air flow”
ventilation setting. (The operation
light is flashing.)
■ It is because the refrigerant leakage sensor started working:
• In case it is making a beeping sound, there is a risk of
refrigerant leakage. Please ventilate the room and contact your
dealer.
• When there is no beeping sound, then there is no refrigerant
leak, or it is still doing detection.
If there is no leak, it will return to the previous mode of
operation automatically after a few minutes.
Sometimes, the refrigerant leakage sensor detects by mistake
substances other than refrigerant, such as insecticides or
hairsprays (only for R32 refrigerant).
Other.
The fan of indoor / outdoor unit is
spinning when the unit is turned
off.
■ When the fan of indoor unit is spinning and the operation light is
flashing, it is because the refrigerant leakage sensor started
working:
• In case it makes a beeping sound, there is a risk of refrigerant
leakage. Please ventilate the room and contact your dealer.
• When there is no beeping sound, then there is no refrigerant
leak, or it is still doing detection.
If there is no leak, the fan will stop automatically in a few minutes.
Sometimes, the refrigerant sensor detects by mistake
substances other than refrigerant, such as insecticides or
hairsprays (only for R32 refrigerant).
Other.
Fault diagnosis by remote
controller show the code A0 on
the display of remote controller.
■ Is it making beeping sound?
• If it is making sound
There is a risk of refrigerant leakage. Please ventilate the room
and contact your dealer.
• If it is not making sound
There is no refrigerant leakage, or it is still doing detection.
Please wait a few minutes.
