PTAC Installation Recommendations
For proper PTAC unit performance and maximum operating life please refer to the minimum installation clearances below:
Figure 1
PTAC units should be installed no closer than 12" apart when two units are side by side. If three of more PTAC units are to operate next to one another allow a minimum of 36" between units. Also, a vertical clearance of 60" should be maintained between units installed.
