Seasonal Wind and Cautions in Winter
In areas with low ambient temperature, high humidity, or heavy snowfall, particular measures are
required to ensure that the unit operates properly.
- Install the unit so that it does not come into direct contact with snow. If snow accumulates and
freezes in the air inlet, the system may malfunction. When installing in an area with heavy
snowfall, attach the hood to the system.
- Install the suction and discharge ducts to prevent the entry of snowfall or rainfall.
- When installing in an area with heavy snowfall, install it on an installation console which is 500mm
higher than the average snowfall (annual average snowfall).
- The height of the H frame must be at least twice the amount of snowfall and its width must not
exceed the width of the unit. (Snow may accumulate if the width of the frame is wider than the
width of the unit.)
- If condensed water from the outdoor unit freezes around the product, the floor/ground may
become slippery and cause an accident, so do not install the outdoor unit near a sidewalk. If it is
unavoidable, install a water channel or drainage pipe to prevent condensed water from flowing
onto the sidewalk.
- If more than 100mm of snow has accumulated on the top of the product, be sure to remove the
snow before carrying out any work on the unit.
- Do not install the inlet or outlet of the unit so that they face seasonal winds.
- Make preparations for snow and/or seasonal winter winds in all areas in which the unit is installed.
