Building Exterior Unit Opening Requirements
be installed no closer than 12” apart when two units are side by side. If three or more units are to operate next to one
with adjacent, outset units, a minimum distance of 64” must be kept between units (Figure C). Also, a vertical clearance of
ground.
Grill Clearance Requirements
Where obstructions are present use the
following guidelines for proper spacing from
the VPAK exterior louvered grill. Friedrich
recommends that ALL obstructions are a
minimum of 72” from the exhaust.
For minor obstruction(s) such as lamp poles
or small shrubbery, a clearance of 24” from
the outdoor louver must be maintained.
For major obstructions such as a solid
fence, wall, or other heat rejecting devices
like a condensing unit, a minimum distance
of 72” must be kept.
