Applied Packaged Terminal Air Condition-
ers are designed and built for through-the-wall installation in
either new or existing buildings. The self-contained refriger-
ant system delivers cooling to the desired space. Heating can
be accomplished with electric resistance, with hydronic (wa-
ter or steam), hydronic with intermediate electric resistance.
Generally, an estimate for capacity selection is 35 BTUH
per square foot of oor space (cooling) and 4 BTUH (1.25
watts) per cubic foot (heating). The architect or engineer
must verify the selection. The unit will restart at its last set-
ting after a power interruption.
