CLEARANCES

UNIT CLEARANCES
*In situations that have multiple units, a 48" minimum clearance
is required between the condenser coils.
Maintain an adequate clearance around the unit for safety,
service, maintenance, and proper unit operation. Leave a
clearance of 48" on all sides of the unit for possible compres-
sor removal or service access, and to ensure proper ventila-
tion and condenser airflow. Do not install the unit beneath any
obstruction. Install the unit away from all building exhausts to
inhibit ingestion of exhaust air into the unit's fresh-air intake.
