About this detail

The VAV or CV box is suspended from the structure using galvanized sheet metal straps. Hot water supply and return lines connect to the unit via unions, ball valves, a calibrated balancing valve, and a strainer with a valve, hose end, and chained cap. An automatic temperature control valve is installed in the vertical position along with 3/8-inch vent lines, air vents, reducers, and a 1/2-inch drain valve. Pipe sizes are determined per the project plans with reductions made at unit connections as necessary.
