Precautions about installation in regions with extreme snowfall and cold
temperatures
To ensure the outdoor unit operates properly, certain measures are required in locations where there
is a possibility of heavy snowfall or severe wind chill or cold :
1
Prepare for severe winter wind chills and heavy snowfall, even in areas of the country where these
are unusual phenomena.
2
Position the outdoor unit so that its airflow fans are not buried by direct, heavy snowfall.
If snow piles up and blocks the airflow, the system may malfunction.
3
Remove any snow that has accumulated 100 mm or more on the top of the outdoor unit.
4
Place the outdoor unit on a raised platform at least 500 mm higher than the aver- age annual
snowfall for the area. If the frame width is wider than the outdoor unit, snow may accumulate.
5
Install a snow protection hood.
6
To prevent snow and heavy rain from entering the outdoor unit, install the suction and dis- charge
ducts facing away from direct winds.
7
Additionally, the following conditions should be taken into consideration when the unit operates in
defrost mode:
- If the outdoor unit is installed in a highly humid environment (near an ocean, lake, etc.), en- sure
that the site is well-ventilated and has a lot of natural light. (Example: Install on a rooftop.)
