PTAC Installation Recommendations
For proper PTAC unit performance and maximum operating life 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 or 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. In the interior of the room the unit should be located a minimum of 1/4" from the floor and a minimum of 36" from the ceiling.
