Model AH-170 Plenum Installation
The model AH-170 can be used in conjunction with an existing furnace or as a
standalone unit. If incorporating it with a return air system, a return air plenum must be
built. The size of the plenum opening can be up to 21" x 21" square. Before installing
the plenum, the air filters and filter rack may be removed. Notch out the area where
the conduit and wiring run into
the top blower housing box.
Attach the plenum and
install an inline filter.
