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 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.

For PTACs on the ground floor or anytime obstructions are present, use the following guidelines:

For minor obstructions such as lamp poles or small shrubbery a clearance of 12" from the outdoor louver should be maintained.

For major obstructions such as a solid fence, wall or other heat rejecting device like a condensing unit, a minimum distance of 36" should be kept.
