Installation
Information in this section is provided for the convenience of the service
technician, for the purpose of evaluating the installation during service
and troubleshooting. It does not take the place of the complete Arm-
strong Installation and Maintenance Instructions that are shipped with
every Magic-Pak unit. If you are installing an Armstrong product and
need a copy of the Installation and Maintenance Instructions, consult the
table below and contact the Armstrong factory.

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.
