Figure 4: Conditioned Unventilated Basement Installation
Always select a return from a central location in the structure in an area that is always open to the rest of the
structure.
Do not use a return from a room that often may have its door closed. If the structure in which the unit is to be
installed has an existing forced air HVAC system, utilize the HVAC system to make the DRYCOOL™ HD unit
installation easier.

: Install a separate 8" return duct for the DRYCOOL™ HD in a central area of the
structure. Duct the supply of the DRYCOOL™ HD to an 8" x 8" x 8" tee/damper that is 20% open to the
basement. Duct the other side of the tee to the air supply of existing HVAC system. Connect 8" ducts to the
reactivation inlet and outlet to supply ambient air for reactivation and to expel moist air outside the basement.
