Setting the Unit

CAUTION
In order to avoid injury, take proper precaution when
lifting heavy objects.
CAUTION
Sharp sheet metal edges can cause injury. When
installing the unit, avoid accidental contact with
sharp edges.
Outdoor units operate under a wide range of weather con-
ditions; therefore, several factors must be considered
when positioning the outdoor unit. The unit must be posi-
tioned to give adequate clearances for sufficient airflow
and servicing. A minimum clearance of 24 inches (610 mm)
between multiple units must be maintained. Refer to figure
2 for installation clearances.
