7.6 Outdoor Air-Cooled Condensing Unit Installation
NOTE: Follow all national and local building, electrical and plumbing codes.
7.6.1 Location Considerations
To ensure a satisfactory air supply, locate air-cooled propeller fan condensing units in an environment
providing clean air, away from loose dirt and foreign matter that may clog the coil. Condensing units must
not be located in the vicinity of steam, hot air or fume exhausts or closer than 18 inches from a wall,
obstruction or adjacent unit. Avoid areas where heavy snow will accumulate at air inlet and discharge
locations.
The condensing unit should be located for maximum security and maintenance accessibility. Avoid
ground-level sites with public access.
Install a solid base, capable of supporting the weight of the condensing unit. The base should be at least 2
inches higher than the surrounding grade and 2 inches larger than the dimensions of the condensing
unit base. For snowy areas, a base of sufficient height to clear snow accumulation must be installed.
