Installation Manual
Keep the indoor unit, outdoor unit, power supply wiring, and
transmission wiring at least 1 meter away from televisions and
radios. This is to prevent image interference and noise in those

The ceiling is horizontal and its structure can withstand
the weight of the indoor unit.
The inlet and outlet are not impeded, and the
