These units operate under a wide range of weather conditions;
therefore, several factors must be considered when positioning the
outdoor unit. The unit must be positioned to give adequate clearances
for sufficient airflow and servicing.
S
Install unit level or, if on a slope, maintain slope tolerance of 2
degrees (or 2 inches per 5 feet [50 mm per 1.5 m]) away from
building structure.
S
Install the unit high enough above the ground or roof to allow
adequate drainage of defrost water and prevent ice or snow
build−up.

occur. The unit base should be elevated above the depth of
average snows. Stand−off kits are available for ordering using
either catalog numbers
