Vert-I-Pak Installation Recommendations

For proper unit performance and maximum operating life please refer to the minimum installation clearances

below.

Figure 1

VERT-I-PAK® units must be installed on an outside wall. Con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 oor should be mounted at least 6" off of the ground.

Figure 2

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.

The above suggestions are for reference only and do not represent all possible installations. Please contact the factory for information regarding affects of other installation arrangements.

By following these simple recommendations you can be condent that your Friedrich Vert-I-Pak® will provide years of worry-free operation.
