10. Installation
Outdoor unit
WARNING
• Should adopt bar type louver. Don't use a type of rain
resistance louver.
[Bar type louver]
• Louver specifications.
– Angle criteria : less than 20˚
– Opening ratio criteria : greater than 80%
Installing the outdoor unit in cold region
• In cold regions with lots of snowfall, install a snow prevention
duct, as a sufficient countermeasure, to prevent snow from
accumulating on the outdoor unit. When the snow prevention
duct is not installed, frost may accumulate on the heat
exchanger and heating operation may not work normally.
• Air outlet of the duct should not be directed to the enclosed space.
CAUTION
• Cautions regarding on installing the frame and selecting the
base ground
– Height (h) of the frame and the base ground should be
higher than the "heaviest expected snowfall".
– Area of the frame and the base ground should not be larger
than the are of the outdoor unit. Snow may accumulate if
the area of the frame or the base ground is larger.

Installing the outdoor unit in windy region
• In windy regions such as near sea shores, protection wall or
wind protection duct must be installed for normal operation
of the outdoor unit. (Refer to the illustration of the snow
prevention duct, for installing the wind protection duct.)
• Install the wind prevention duct with the consideration of
major wind direction. If the direction of the discharge part is
same as major direction of the wind, it could cause product's
performance decrease.
CAUTION
• Cautions regarding on installing the frame and selecting the
base ground
– The base ground must be solid and the outdoor unit must
be fixed with anchor bolts.
– Make sure to install outdoor unit in a place strong enough
to withstand its weight. If the place cannot withstand the
weight of the outdoor unit, outdoor unit may fall and cause
personal injury.
– When installing on a rooftop subject to strong wind,
countermeasures must be taken to prevent the unit from
falling down.
– Use a frame that is resistant to corrosion.
