Be sure that the fan dischargedoes not recirculate to the condenser coil. Do not locate the unit ineither a corner or under an overhead obstruction. The minimumclearance under a partial overhang (such as a normal houseoverhang) is 48--in. (1219.19 mm) above the unit top. Themaximum horizontal extension of a partial overhang must notexceed 48--in. (1219.19 mm).Do not place the unit where water, ice, or snow from an overhangor roof will damage or flood the unit. Do not install the unit oncarpeting or other combustible materials.
