location selection
Select a location for installing the 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 Space II 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 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. Install a snow protection hood.
4. To prevent snow and heavy rain from entering the 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 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 Space II unit may accumulate moisture after unit operates in defrost mode that can turn to ice.
The 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
•
Avoid exposing the Space II 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, and other sources of extreme temperature, gases, or substances that may degrade performance or cause damage
to the unit.
•
When installing multiple Space II units, avoid placing the units where discharge of one Space II unit will blow into the inlet side of an
adjacent unit.
