Hold the plug by the head
not the cable when taking
it out.
For inner cleaning, contact an Authorized Service Center or a dealer.
Do not use harsh detergent that causes corrosion or damage on the unit.
Harsh detergent may also cause failure of product, fire, or electric shock.
Install the product so the exhaust and noise
are not aimed directly at the neighbors.
Be considerate.
When gas leaks, open the
window for ventilation before
operating the unit.
Follow installation instructions exactly.
Never touch the metal parts
of the unit when removing
the filter.
