fresh air opening in the bulkhead. Depending on the fresh air damper
location, the blower expels the air through a filter thus removing air-
born particles. Then the air is forced through the evaporator coil
which removes the moisture and heat. It is then distributed to the
conditioned space. The condenser fan draws the air from the outside
through the louvers and expels it through the condenser coil absorbing
the heat from the condenser coil.
