1.2. During operation
Caution:
• Do not use any sharp object to push the buttons, as this may
damage the remote controller.

age the remote controller and cause malfunction.

lets. Tall items of furniture underneath the indoor unit, or bulky
items such as large boxes placed close to the outdoor unit will
reduce the unit’s efficiency.

wet hands. An electric shock may result.

• Do not place a gas heater or any other open-flame appliance where
it will be exposed to the air discharged from the unit. Incomplete
combustion may result.
