UNIT CLEARANCES
Adequate clearance around the unit should be kept for safety,
service, maintenance, and proper unit operation. A total clear-
ance of 75" on the main control panel side of the unit is rec-
ommended to facilitate possible fan shaft, coil, electric heat
and gas furnace removal. A clearance of 48" is recommended
on all other sides of the unit to facilitate possible compressor
removal, to allow service access and to insure proper venti-
lation and condenser airflow. The unit must not be installed
beneath any obstruction. The unit should be installed re-
mote from all building exhausts to inhibit ingestion of exhaust
air into the unit fresh air intake.
