About this detail

Piping arrangement for a fan coil unit, including supply and return lines equipped with isolation valves, strainers, unions, pressure-temperature test plugs, manual air vents, control valves, and combination shutoff/balance valves with memory stops. Concentric reducers are provided where required along the piping run. The condensate drainage system consists of primary and secondary condensate connections with minimum two-and-a-half-inch deep traps and a vent to atmosphere. Units lacking an integral secondary drain pan require a twenty-four gauge galvanized sheet metal auxiliary pan installed underneath with a three-quarter-inch secondary drain connection.
