Location

Magic-Pak HW/HWC units are designed and certified for through-the-wall installations only and must not be installed in any other type of applica- tion. The interior portions of the unit may be surrounded by a closet with clearances to combustible material held to 0" at sides, 2" top and 1" front and plenum. Adequate clearance must be provided to install the union and manual shutoff valve as well as providing accessibility to the field wiring junction box. Do not install directly on carpeting, tile or other combustible material other than wood flooring.

Magic-Pak HW/HWC units should be installed in an outside building wall that is clear of obstructions which might impede the free intake and discharge of condenser air.

A building wall should be no closer to an opposite building wall than 2' for every floor or Magic-Pak unit in a vertical array facing the wall. For example, a one-story building with a Magic-Pak HW/HWC unit should be a minimum of 2' from the wall facing the unit, and if the facing wall also has a Magic-Pak unit, the two walls should be at least 4' apart.

A six-story building with six Magic-Pak units in a vertical array should be at least 12' from the opposite building wall, and if that building wall also contains Magic-Pak units, the building should be at least 24' apart.

Buildings taller than six stories need not exceed the separation needed for six-story buildings.
