Vert-I-Pak Installation Recommendations

Forproperunitperformanceandmaximumoperatinglife pleaserefertotheminimuminstallationclearancesbelow.

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 heat rejecting

device like a condensing unit, a mini-

mum distance of 72" should be kept.
