WARNING: Installation, disassembly, repair and maintenance must be performed only by qualified personnel. All gas MUST be evacuated from the system before starting repairs. Remove the entire valve before performing repairs. Emergency service, on the actuator and lower stem assembly portion of the valve only, may be carried out with the valve installed, provided downstream pressure is relieved under the same conditions required for releasing LP-Gas, as in the caution below, and that there is positive assurance that the valve is closed tight with no leakage past the main seat disc. Installation, usage and maintenance of this product must be in compliance with all Engineered Controls International, Inc. instructions as well as requirements and provisions of NFPA #54, NFPA #58, DOT, ANSI, all applicable federal, state, provincial and local standards, codes, regulations and laws. Inspection and maintenance on a periodic basis is essential. Be sure all instructions are read and understood before installation, operation and maintenance. These instructions must be passed along to the end user of the product. CAUTION: Contact or inhalation of liquid propane, ammonia and their vapors can cause serious injury or death! NH3 and LP-Gas must be released outdoors in air currents that will insure dispersion to prevent exposure to people and livestock. LP-Gas must be kept far enough from any open flame or other source of ignition to prevent fire or explosion! LP-Gas is heavier than air and may not disperse or evaporate rapidly if released in still air. Disassembly and Repair Procedure CAUTION: READ THROUGH ALL OF THESE INSTRUCTIONS, INCLUDING THE NOTICE AND WARNINGS BEFORE BEGINNING ANY DISASSEMBLY OR REPAIR. NOTE: Before repairing valve, thoroughly examine valve lever and all associated parts for excessive wear. Check handle for proper function. Any components that are not in good condition and not fully operational should be replaced during repairs. Repairs must be performed in a clean area. Hands, clothing, tools and work area must be completely free of oil, grease, and foreign matter to prevent contamination of component parts and valves. Manual/Pneumatic Actuator Disassembly NOTE: The standard A3212A Series is equipped with a manual actuator. It is possible that the valve under repair has been fitted with a A3212PA pneumatic actuator. Please follow the disassembly and reassembly procedures for the appropriate actuator.

Lubricate the shaft and carefully insert through the seal housing, with retaining ring on outside of housing as shown in the diagram. 3. Lubricate the two new pressure seal rings, new jam ring, and the washer saved from disassembly. Assemble these one piece at a time over the stem and into the seal housing, as shown in diagram. Be careful not to damage any pieces on the flat
edges of the stem. 4. Holding the seal housing and pivot shaft in a vertical position, place the new spring onto the washer in the seal housing. 5. Position the new seal housing gasket onto the edge of the seal housing. 6. Carefully to insure proper position of the gasket, slide the bushing onto the pivot shaft and thread onto the seal housing. Tighten with a 1 5 /8" wrench on bushing and 1 3 /8" wrench on the seal housing. 7. Slide the insert onto the pivot shaft and into the recess of the bushing. 8. Slide the friction washer onto pivot shaft. 9. Place the new retaining ring onto the grooved area of pivot shaft. 10. Set assembly aside. Disc Retainer and Poppet Stem Assembly 1.
