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.
Figure 2
For PTACs on the ground fl oor 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.
The above suggestions are for reference only and do not represent all possible installations. Please contact the factory for
