ENGLISH
During the installation of the unit, consider service, inlet, and outlet
acquire the minimum space as shown in the figures below.
Seasonal wind and cautions in winter
• Sufficient measures are required in 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 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.

• The height of the wall on the front side
must be 1500mm or less.
• The height of the wall on the inlet side
must be 500mm or less.
• There is no limit to the wall on the side.
• If the height of the walls on the front and
the side are higher than the limit, there
must be additional space on the front and
the side.
- Additional Space on the front side by
1/2 of h1
- Additional Space on the inlet side by 1/2
of h2
- h1 = A(Actual height) - 1500
- h2 = B(Actual height) - 500
