About this detail

Side and end views show a variable air volume box installed above a ceiling with a dedicated twenty-four by thirty-six inch access space indicated by crosshatching. Hot water supply and hot water return piping connect to the reheat coil, equipped with a balancing valve, control valve, shutoff valve, manual air vent, and typical drain valves. A removable ceiling tile or ceiling access panel is positioned directly below the required access space to allow entry to the VAV control panel and heat pump cabinet access panel. The contractor must maintain this clearance zone free from interfering hydronic, plumbing, process, sprinkler, ductwork, or electrical installations unless authorized by the owner's representative.
