Selecting the best location

Select a location for installing the outdoor unit that will meet the following conditions:
• Where the unit will not be subjected to direct thermal radiation from other heat sources.
• Where operating sound from the unit will not disturb inhabitants of surrounding buildings.
• Where the unit will not be exposed to direct, strong winds.
• Where there is enough strength to bear the weight of the unit.
• Include space for drainage to ensure condensate flows properly out of the unit when it is in heating mode.
• Include enough space for air flow and for service access.
• To avoid the possibility of fire, do not install the unit in an area where combustible gas may generate, flow, stagnate, or leak.
• Do not install the unit in a location where acidic solution and spray (sulfur) are often used.
• Do not use the unit in environments where oil, steam, or sulfuric gas are present.
• Install a fence to prevent vermin from crawling into the unit or unauthorized individuals from accessing it.
To ensure the outdoor unit operates properly, certain measures are required in locations where there is a possibility of heavy snowfall or
severe windchill 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 3-15/16 inches or more on the top of the outdoor unit.
4. Place the outdoor unit on a raised platform at least 19-11/16 inches higher than the average annual snowfall for the area. In environments
where there is a possibility of heavy snow, the frame height must be more than two (2) times the amount of average annual snowfall, and
should not exceed the width of the outdoor unit. 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 discharge ducts facing away from direct winds.
Additionally, the following conditions should be taken into considerations when the unit operates in defrost mode:
• If the outdoor unit is installed in a highly humid environment (near an ocean, lake, etc.), ensure that the site is well-ventilated and has a lot
of natural light. (Example: Install on a rooftop.)
• Sidewalks or parking lots near the outdoor unit may accumulate moisture after unit operates in defrost mode that can turn to ice.
The indoor unit may take longer to provide heat, or heating performance will be reduced in winter if the unit is installed:
1. In a narrow, shady location.
2. near a location that has a lot of ground moisture.
3. In a highly humid environment.
4. In an area in which condensate does not drain properly.
