THE INDOOR UNIT INSTALLATION
56
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.)
