This diagram details the piping arrangement for multiple hydronic coils connected to supply and return mains. Piping at the coil ends includes offsets to allow for the removal of coils during maintenance. Three or more coils are piped similarly in a parallel configuration. A modulating pressure independent control valve is provided where the design flow rate exceeds 10 gallons per minute.
SUPPLY RETURN COIL (TYP) A. OFFSET PIPING AT COIL ENDS TO ALLOW REMOVAL OF COILS. B. THREE OR MORE COILS PIPED SIMILARLY. C. PROVIDE MODULATING PRESSURE INDEPENDENT CONTROL VALVE WHERE DESIGN FLOW RATE EXCEEDS 10 GPM. GENERAL NOTES: NC NONE 2 HYDRONIC COIL - AIR HANDLER - TWO-WAY - PIPING DIAGRAM
