Be very careful while carrying the product.

•Do not have only one person carry product if it is more than 20 kg (44 lbs).

•PP bands are used to pack some products. Do not use them as a mean for transportation because they are dangerous.

•Do not touch heat exchanger fins with your bare hands. Otherwise you may get a cut in your hands.

•Tear plastic packaging bag and scrap it so that children cannot play with it. Otherwise plastic packaging bag may suffocate children to death.

•When carrying in Outdoor Unit, be sure to support it at four points. Carrying in and lifting with 3-point support may make Outdoor Unit unstable, resulting in a fall.

•Use 2 belts of at least 8 m (26.2 ft) long.

•Place extra cloth or boards in the locations where the casing comes in contact with the sling to prevent damage.

•Hoist the unit making sure it is being lifted at its center of gravity.

Seasonal Wind and Cautions

in Winter

-Sufficient measures are required in a snow area or severe cold area in winter so that product can operate well.

-Get ready for seasonal wind or snow in winter even in other areas.

-Install a suction and discharge duct not to let in snow or rain.

-Install the outdoor unit not to come in contact with snow directly. If snow piles up and freezes on the air suction hole, the system may malfunction. If it is installed at snowy area, attach the hood to the system.

-Install the outdoor unit at the higher installation console by 50 cm than the average snowfall (annual average snowfall) if it is installed at the area with much snowfall.

-Where snow accumulated on the upper part of the Outdoor Unit by more than 10 cm, always remove snow for operation.
