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.

Caution:

• Do not use any sharp object to push the buttons, as this may damage the
remote controller.

• Never block or cover the indoor or outdoor unit’s intakes or outlets.

Warning:

• Do not remove the front panel or the fan guard from the outdoor unit when it
is running. You could be injured if you touch rotating, hot or high-voltage
parts.

• Never insert fingers, sticks etc. into the intakes or outlets, otherwise injury
may result, since the fan inside the unit rotates at high speed.

• If you detect odd smells, stop using the unit, turn off the power switch and
consult your dealer.

• This air conditioner is NOT intended for use by children or infirm persons
without supervisions.

• Young children should be supervised to ensure that they do not play with

When you need to dispose of the unit, consult your dealer. If pipes are removed
incorrectly, refrigerant (fluorocarbon gas) may blow out and come into contact with
your skin, causing injury. Releasing refrigerant into the atmosphere also damages
the environment.
