PLACEMENT CONSIDERATIONS Selecting the Best Location DANGER cause serious bodily injury or death. Install a fence to prevent vermin from crawling into the unit or unauthorized individuals from accessing it. Do not install the unit in a location where acidic solution and spray (sulfur) are often used as this may cause serious bodily injury or death. Do not use the unit in environments where oil, steam, or sulfuric gas are present as this may cause serious bodily injury or death. - Page 42 PLACEMENT CONSIDERATIONS Indoor Unit Clearance/Outdoor Unit Installation Figure 12: Single Zone Indoor Unit Clearance Requirements.
