Vert-I-Pak Installation Recommendations
Forproperunitperformanceandmaximumoperatinglifepleaserefertotheminimuminstallationclearancesbelow.
FigureI
VERT-I-PAK ®units must be installed on an outside wall. Confined 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 floor 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 heatrejecting
device like a condensing unit, a mini-
mum distance of 72" should be kept.
