PTAC Installation Recommendations
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 oor and a minimum of 36"
from the ceiling.
• 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.
For proper PTAC unit performance and maximum operating life refer to the minimum installation clearances
below:
For PTACs on the ground floor or anytime obstructions are present, use the following guidelines:
