outdoor coil-air inlet to prevent obstruction of airflow by grass or
shrubs. Do not secure the unit to the slab except when required by
local codes.

PROVIDE CLEARANCES
The required minimum service clearances are shown in Fig. 2-5.
Adequate ventilation and outdoor air must be provided. The
outdoor fan pushes air through the outdoor coil and discharges it
through the louvers on the top cover, the decorative grille, and the
compressor access panel. Be sure that the fan discharge does not
recirculate to the outdoor coil. Do not locate the unit in either a
corner or under an overhead obstruction. The minimum clearance
under a partial overhang (such as a normal house overhang) is 48
in. above the unit top. The maximum horizontal extension of a
partial overhang must not exceed 48 in.
IMPORTANT:
Do not restrict outdoor airflow. An air restriction
at either the outdoor-air inlet or the fan discharge may be
detrimental to compressor life.
Do not place the unit where water, ice, or snow from an overhang
or roof will damage or flood the unit. Do not install the unit on
carpeting or other combustible materials. Slab-mounted units
