Recommended Effective Opening Ratio(E.O.R) of Louver
CAUTION
Be very careful to carry 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 of it.
• Use 2 belts of at least 8 m (3.3 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.

Cautions in winter especially for seasonal wind
• Sufficient measures are required at a snow area or severe cold area
in winter so that product can be operated well.
• Get ready for seasonal wind or snow in winter even in other area.
• 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.
• Don't install the suction hole and discharge hole of the outdoor unit
facing to the seasonal wind.
• Please install the product so that the door of the outdoor unit room is
completely opened for smooth installation and service.
• A water drain outlet is required to discharge rain water on the bottom
of the outdoor unit room or condensation water to possibly generate
when operating.
• The recommended Specification of louver
• Multi V Space should be installed in the special outdoor room with
soundproofing walls.
CAUTION
Do not use bended louver like the above Fig.
It disturbs the air circulation.

WARNING
LIFTING METHOD
• When carrying the suspended, unit pass the ropes under the unit and
use the two suspension points each at the front and rear.
