ABSTRACT:
A zone-control unit adapted for facile inclusion in a building's ductwork includes a mechanical terminal unit, inlet and outlet piping assemblies that are mechanically coupled together. The structure also includes at least one handle so the zone-control unit may be conveniently and safely handled both during shipping, and during installation into a HVAC system. Prior to installation into a HVAC system the fully-functional zone-control unit also includes a pair of caps respectively sealing the ends of the piping assemblies, and a pressure gauge for sensing pressurization of the piping assemblies and coil which the caps seal. Sealed in this way a pressure gauge permits testing to assure that the piping assemblies and coil are leak free, and readily assessing that zone-control units remain leak free until they are about to be installed into a building's HVAC system.
