Attic Installation Horizontal Flow Air Handler | HVAC Airflow
This is a horizontal flow air handler installed in the attic. Notice the drain pan under the air handling unit to catch condensation if the primary pan were to overflow. This is the secondary condensation pan which is installed under the air handler to save a ceiling.
Also slightly visible is a float switch which offers triple protection against flooding in an attic if the primary drain were to plug up. The primary and secondary drains coming from the air handler also drain into condensation pumps. These pumps have floats inside them and a reservoir. (more…)
