any such material on the unit for long, as it may damage or
cause fading on the surface of the unit.

Maintenance After a Long Break Period
(e.g. at the beginning of the season)
Check and remove everything that might be blocking inlet
and outlet vents on the indoor units and outdoor units.

"Cleaning the Air Filter" for details on how to proceed, and
make sure to install cleaned air filters back to the same
position.
Cleaning the Air Filter
The air filter can prevent dust or other particles from going
inside. In the case of blockage of the filter, the working
efficiency of the air conditioner may drastically decrease.
Therefore, the filter must be cleaned once every two weeks
during long time usage.
If the air conditioner is installed in a dusty place, clean the
the air filter frequently.
If the accumulated dust is too heavy to be cleaned, please
replace the filter with a new one (a replaceable air filter is
an optional fitting).
All filter cleaning should be performed by a suitable
handyperson.

7. THE FOLLOWING SYMPTOMS ARE
NOT AIR CONDITIONER TROUBLES
Symptom 1: System does not operate
The air conditioner fails to start immediately after the ON/OFF
button on the remote controller is pressed. If the operation lamp
lights up, then the system is in normal condition. To prevent
overloading of the compressor motor, the air conditioner starts 3
minutes after it is turned ON.
If the operation lamp and the
heating type) or "Fan-Only" indicator (cooling-only type)
up, it means that you chose heating mode. When just booting, if
the compressor has not started, the indoor unit appears as
"anti cold wind" protection, due to overflow outlet temperature.
