A1
This does not abnormal. It
is because the cold wind
prevention is working.
In "automatic wind speed" mode, the
indoor fan changes from strong wind
to weak wind to slight wind.
Common, etc.
Q1
Q2
At operation startup, the outdoor unit
becomes noisy.
The outdoor unit sometimes changes
in its noise. Q3
Q4
There is a difference between the
temperature setting and room temperature
in room temperature control.
The product will not produce wind
right after startup.
Q5
Q6
I performed internal cleaning, but
didn't succeed in controlling the mold
in the room.
Internal cleaning will clean the inside of the indoor unit of the
air-conditioner, thereby controlling mold generation. This will
not control the mold in the room.
A6
After turning ON the power switch or breaker, setting the
product to heating or dehumidification will activate a
preliminary operation for 1 minute. At that time, heating will
cause the operation lamp to blink. This is not a sign of a
breakdown.
A5
The room structure, air stream, or other factor may cause a
gap between the room temperature setting and actual room
temperature. If there is any difference between the setting
and the room temperature, adjust the temperature setting to
match the living space to a comfortable temperature.
A4
The difference between the thermometer temperature
setting and room temperature will change the rotation speed
of the compressor. This is not a sign of a breakdown.
A3
At operation startup, the product will set the rotation speed
of the compressor to full power and increase its heating and
cooling capacity, resulting in a slightly higher noise level.
This is not a sign of a breakdown. A2
In wind speed "automatic" mode,
the product will sense the heat
exchange temperature and,
when the temperature goes
down, the product will
automatically switch to strong
wind to weak wind to slight wind.
