1.2. During operation
Caution:
•
Do not use any sharp object to push the buttons, as this may
damage the remote controller.
•
Do not twist or tug on the remote controller cord as this may dam-
age the remote controller and cause malfunction.
•
Never block or cover the indoor or outdoor unit's intakes or out-
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.
Warning:
•
Do not splash water over the unit and do not touch the unit with
wet hands. An electric shock may result.
•
Do not spray combustible gas close to the unit. Fire 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.
