Installation
Horizontal application
Horizontal applications will normally be used in an attic
or crawl space. This type of installation requires supply air
plenum or duct to be connected to the supply collar and a
return air plenum or duct be attached to the unit inlet collar.
The supply ducts will be connected to the supply air plenum
and routed through the attic to a register in each room. Use
a Non-tape sealant such as mastic or an aerosol sealant to
prevent leaks in the ducts and the plenum.
The opposite end of the return air duct is attached to a return
tape sealant such as mastic or an aerosol sealant to prevent
leaks in the ducts and the plenum.
