*In situations that have multiple units, a 48” minimum clearance is
required between the condenser coils.
Adequate clearance around the unit should be kept for safety, ser-
vice, maintenance, and proper unit operation. A total clearance
of 75” on the main control panel side of the unit is recommended
to facilitate possible fan shaft, coil, and electric heat. A clearance
of 48” is recommended on all other sides of the unit to facilitate
possible compressor removal, to allow service access and to in-
sure proper ventilation and condenser airflow. The unit must not
be installed beneath any obstruction. The unit should be installed
remote from all building exhausts to inhibit ingestion of exhaust
air into the unit fresh air intake.
