Selecting the Best Location

DANGER

•

Do not install the unit in an area where combustible gas may generate, flow, stagnate, or leak. These conditions can cause a fire, resulting

in bodily injury or death.

•

Do not install the unit in a location where acidic solution and spray (sulfur) are often used as it can cause bodily injury or death.

•

Do not use the unit in environments where oil, steam, or sulfuric gas are present as it can cause bodily injury or death.

CAUTION

• When the outdoor unit operates in defrost mode, sidewalks or parking lots near the unit may accumulate moisture that can turn to ice, resulting

in slipping and personal injury.

Note:

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.

• Install a fence to prevent vermin from crawling into the unit or unauthorized individuals from accessing it. Maintain all recommended clearances.

Note:

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 4 inches or more on the top of the outdoor unit.

4. Place the outdoor unit on a raised platform at least 20 inches higher than the average 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 discharge 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.), ensure that the site is well-ventilated and has a lot of

natural light. (Example: Install on a rooftop.)

Note:

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.

Ambient Air Conditions

WARNING

• Avoid exposing the unit to sources of extreme temperature or gases to prevent serious bodily injury.

Note:

• Avoid exposing the outdoor unit to steam, combustible gases, or other corrosive elements.

• Avoid exposing the unit to discharge from boiler stacks, chimneys, steam relief ports, other air conditioning units, kitchen vents, plumbing

vents, or substances that may degrade performance or cause damage to the unit.

• When installing multiple outdoor units, avoid placing the units where discharge of one outdoor unit will blow into the inlet side of an adjacent unit.
