Vert-I-Pak Installation Recommendations
For proper unit performance and maximum operating life please refer to the minimum installation clearances
below.
Fig ure 1
VERT-I-PAK® units must be installed on an outside wall. Confi ned spaces and/or covered areas should be
avoided. Units should be installed no closer than 12" apart when two units are side by side. If three of more
units are to operate next to one another allow a minimum of 60" between units or pairs of units. Also, a vertical
clearance of 60" should be maintained between units. Units installed on the bottom fl oor should be mounted
at least 6" off of the ground.

Any time obstructions are present use
the following guidelines for proper
spacing from the VERT-I-PAK louver:
• For minor obstructions such as lamp
poles or small shrubbery a clearance
of 24" 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 72" should be kept.
