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.
• Install the outdoor unit at the higher installation console by 50cm than the average snowfall (an-
nual 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 10cm, always
remove snow for operation.
- The height of H frame must be more than 2 times the snowfall and its width shall not ex-
ceed the width of the product. (If width of the frame is wider than that of the product,
snow may accumulate)
- Don't install the suction hole and discharge hole of the Outdoor Unit facing the seasonal
wind.

Air guide work

In case of out door unit is located outdoor cabin of apartment or flats, then the efficiency can
drop and system pressure increases thus finally damaging the compressor or other components
in the system by heat short circuit.
• Do not use bended louver. It disturbs the air circulation.
• The opening ratio is at least 80%
• Louver angle is 0-20 degree
• Louver pitch will be as more than 100mm
• If you have a insect control net, consider the shielded area and static pressure loss
• Check the static pressure range of outdoor unit fan.
Then, install air guide in the range of static pressure.
