Wind/snow prevention duct

Installing the outdoor unit around the obstacles

f It is necessary to install a discharge guide duct(field supply) to direct exhaust from the fan horizontally, when it is
difficult to provide a minimum space of 2m between the air outlet and a nearby obstacle.
Discharged air
Ex.) Balcony

Installing the outdoor unit in cold region

f 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.
f Air outlet of the duct should not be directed to the enclosed space.
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".
CAUTION
• 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.
