OC Sportsplex Pool HVAC Unit Replacement <br />PDC Project 23022 Identification for HVAC Piping and <br />Equipment 23 05 53 - 3 <br />4.Fire Alarm/Sprinklers/Life Safety -Red <br />5.Chilled Water Valves/Low point drains/etc.-Blue <br />6.Heating Hot Water Valves/Low point drains/etc.-Red <br />PART 3 EXECUTION <br />3.01 PREPARATION <br />A.Degrease and clean surfaces to receive adhesive for identification materials. <br />3.02 INSTALLATION <br />A.Install nameplates with corrosive-resistant mechanical fasteners,or adhesive. Apply with sufficient <br />adhesive to ensure permanent adhesion and seal with clear lacquer. <br />B.Install tags with corrosion resistant chain. <br />C.All piping and duct shall be labeled at least once in EVERY room.Piping and ductwork shall be <br />labeled every 15 ft and at every change of direction. <br />D.All exposed mechanical piping in mechanical rooms,boiler rooms,on and above mezzanine <br />levels,both insulated and uninsulated,shall be color coded with 30 mil PVC jacketing per the <br />following schedule: <br />1.Chilled Water/Glycol Supply/Return Medium Blue <br />2.Hot Water Supply/Return Medium Red <br />3.Fuel Gas Paint piping Yellow <br />4.Refrigerant Gray <br />E.Install underground plastic pipe markers 6 to 8 inches below finished grade,directly above buried <br />pipe. <br />F.Install ductwork with stencilled painting. Identify with air handling unit identification number and <br />area served. Identify service (supply,return,exhaust,outside air,etc.) Locate identification at air <br />handling unit,at each side of penetration of structure or enclosure,and at each obstruction. <br />G.Provide ceiling grid labels to locate valves or dampers above lay-in panel ceilings. Locate in <br />corner of panel closest to equipment. <br />H.Identify control panels,manual motor starters,combination motor starters,disconnects,variable <br />frequency drives,boiler override switches,boiler emergency switches,and major control <br />components outside panels with plastic nameplates. <br />I.Identify thermostats or temperature sensors relating to air handling units or valves with labels. <br />J.Identify valves in main and branch piping with valve labels. <br />K.Tag automatic controls,instruments,and relays.Key to control schematic. <br />L.Identify air handling units with plastic nameplates indicating unit number,area served,OEM and <br />external static pressure,based on actual equipment submittal data,number and size of filters,and <br />number and size of belts (where applicable). <br />M.Identify pumps with plastic nameplates indicating pump number,system served,GPM,and feet of <br />head. <br />N.Provide ceiling track markers to locate valves or dampers above T-bar type panel ceilings.Locate <br />in corner of panel closest to equipment.Markers shall be installed prior to request for above ceiling <br />inspection. <br />3.03 SCHEDULE <br />A.Standard Color Identification for Mechanical Piping (all labels shall be provided with flow arrows): <br />1.Chilled Water Supply/Return CHWS/CHWR White Lettering/Blue Background <br />2.Hot Water Supply/Return HWS/HWR White Lettering/Red Background <br />3.Makeup Water MUW White Lettering/Green Background <br />4.Fuel Gas Piping GAS Black Lettering/Yellow Background <br />5.Condensate Drain COND Black Lettering/White Background <br />6.Refrigerant REF Black Lettering/Yellow Background <br />Docusign Envelope ID: D4F3B98E-0756-4A0C-A3AD-05AA32D39F1C
