These solenoids have three lead wires with one wire for grounding and a ½” male conduit connection. Catalog No. WT8004A1 is designed to meet Enclosure Type 1 - General Purpose, Types 3 and 3S - Raintight, Types 4 and 4X - Watertight. Catalog No. EF8004A1 meets Enclosure Types 3 and 3S - Raintight, Types 4 and 4X - Watertight, Types 6 and 6P - Submersible, Type 7 (A, B, C & D) Explosionproof Class I, Division 1, Groups A, B, C, & D and Type 9 (E, F, & G) - Dust - Ignitionproof Class II, Division 1, Groups E, F, & G. (See asterisks [*] below) AC (6.3 W) voltages * • 24, 100, 110, 120, 110-120, 220, 220-240 @ 50Hz • 12, 24, 100, 110, 120, 240 @ 60Hz DC (6.9 W) voltages * • 6, 12, 24, 28, 48, 100, 120, 240  = Specific voltage is marked on coil * = Div 1 voltages (UL/CSA, if marked) for EF prefix version. See accompanying regional requirement cert (example, CCC/NEPSI) for voltage, Ex protection and temperature limitations (if marked). OPERATION When the solenoid is energized, the core assembly is drawn into the plugnut/core tube sub-assembly. When the solenoid is de-energized, spring force returns the core assembly to the original position. Enclosure Types 7 and 9 Only (EF8004A1)* To prevent fire or explosion, do not install solenoid and/or valve where ignition temperature of hazardous atmosphere is less than 160 °C. Open circuit before disassembling. Do not exceed temperature limitations in chart below. (See asterisk [*] in DESCRIPTION section). Afin d’éviter le risque de feu ou d’explosion, ne pas installer la bobine ou l’électrovanne ou la température d’inflammation en atmosphère explosible est inferieure à 160 °C. Ouvrez le circuit avant le désassemblage. Ne pas dépasser les limites de température mentionnées dans le tableau ci-dessous. (Voir l’astérisque [*] dans la section descriptive). Temperature Limitations For maximum ambient/fluid temperatures, refer to chart. See valve installation and maintenance instructions for valve temperature limitations. Catalog Numbers Construction Ambient/Fluid Temperature WT8004A1 AC Construction (6.3W) -40 °F(-40 °C) to 140 °F (60 °C) DC Construction (6.9W) -40°F(-40 °C) to 125 °F (52°C) EF8004A1* AC Construction (6.3W) -40 °F(-40 °C) to 104 °F (40 °C) DC Construction (6.9W) -40 °F(-40 °C) to 125 °F (52 °C) (See asterisk [*] in DESCRIPTION section) Positioning Solenoid may be mounted in any position Valve Mounting This solenoid is assembled to a valve that must be rigidly supported using the valve body mounting provisions. WARNING ADVERTISSEMENT NOTICE: See separate valve installation and maintenance instructions for information on: Operation, Positioning, Mounting, Cleaning, Preventive Maintenance, Cause of Improper Operation, Disassembly and Reassembly of basic valve. Wiring To reduce the risk of electrocution, fire, or property damage, wiring must comply with local codes and the National Electrical Code (NEC). Pour réduire les risques d’électrocution, d’incendie ou de dommages matériels, le câblage doit être conforme aux codes locaux et au NEC. To facilitate wiring, the solenoid may be rotated 360° in 90° increments. To rotate solenoid, remove retaining cap (if present) and four mounting screws, reposition solenoid and replace screws and retaining cap (if present). Torque screws evenly in a crisscross manner to 12 in -lbs [1,3 Nm]. Torque retaining cap to 10-12 in - lbs [1,1-1,3 Nm] using a 21/32” socket. The solenoid must be grounded with included grounding wire - do not rely on process pipes for grounding. La bobine doit être mise à la terre avec le fil de terre inclus - ne vous fiez pas aux canalisations pour la mise à la terre. Solenoids have a ½ - 14 NPT male thread. For connection to rigid metal conduit, metal type NPT electrical fittings should be used or use ASCO Part Number 264568-001, supplied. For the explosionproof solenoid (EF8004A1), the female ½ - 14 NPT conduit connector comes preassembled and makes up the full hazardous location solenoid assembly. Any additional required electrical fittings must be approved for use in hazardous locations. Solenoid Temperature Standard solenoids are designed for continuous duty service. When the solenoid is energized for a long period, the solenoid becomes hot and can be touched by hand only for an instant. This is a safe operating temperature. MAINTENANCE To prevent the possibility of death, serious injury or property damage, turn off electrical power, depressurize solenoid valve and vent fluid to a safe area before servicing, Afin d’éviter tout risque de mort, blessure ou dommage, couper l’alimentation électrique, dépressuriser la vanne ou l’électrovanne et vidanger le fluide en zone non dangereuse avant toute maintenance. Potential Electrostatic Charging Hazard. Use wet or damp cloth when cleaning coil, non-metallic pilot or valve body (if applicable). Risque de charges électrostatiques en atmosphères explosibles. Utiliser un chiffon humide ou mouillé lors du nettoyage de la bobine, Corps de pilote ou de vanne non métallique (si applicable). Cleaning (also, see above) All solenoid operators and valves should be cleaned periodically. Time between cleaning will vary depending on medium and service conditions. In general, if the voltage to the solenoid is correct, sluggish valve operation, excessive noise or leakage will indicate that cleaning is required. In the extreme case faulty valve or solenoid operation will occur and the valve or solenoid may fail to shift. Clean strainer or filter when cleaning the valve.
