V. Principles of Operation

The main component of the heat exchangers is counterflow aluminum element through
which heat transfer occurs.
Ambient blower draws ambient air from the bottom inlet through an aluminum mesh air
filter, through the element and exhaust it through a discharge grill.
Cabinet blower draws cabinet air from the top inlet through the element and exhaust it
through the bottom discharge into the cabinet.
