WARNING: Installation, disassembly, repair and maintenance must be performed only by qualified personnel. All gas MUST be evacuated from the system before starting repairs. 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. NOTE: When servicing obsolete 3100 and 7100 Series cylinder valves, a conversion to the o-ring style trim is preferred to straight repair. The o-ring style assembly provides construction that is more resistant to over-torquing on closure or opening to the backseated position. Installation in the field is easier, due to metal-tometal makeup between the body and bonnet and the elimination of retaining compound as a thread sealant. Order Engineered Controls International, Inc. repair kit 3100-81K for conversion to the o- ring style. Disassembly and Repair Procedure CAUTION: READ THROUGH ALL OF THESE INSTRUCTIONS, INCLUDING THE NOTICE AND WARNINGS ON THE BACK OF THIS SHEET, BEFORE BEGINNING ANY DISASSEMBLY OR RE- PAIR. NOTE: 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. A. Disassembly 1. EVACUATE ALL GAS FROM THE SYSTEM BEFORE ANY DISASSEMBLY OR REPAIR. Turn handwheel counter clockwise as far as it will go to release any gas remaining in the container. CAUTION: Do not apply force after valve is fully open and backseated.

Using a screwdriver, remove the handwheel screw and washer by turning counterclockwise--thus allowing removal of the handwheel. Save these parts for reassembly. 3. Place the valve body securely in a vise or hold the body with a wrench if still in the cylinder. Remove the bonnet, turning counterclockwise (right hand thread). A substantial wrench must be used as the bonnet was originally installed using retaining compound. Attached to the bonnet will be the valve stem and diaphragm assembly. 4a. If using repair kit 3100-80A, discard the entire diaphrgam, bonnet and stem assembly. Proceed to the reassembly instructions. 4b. If using repair kit 3100-80B, follow all of the remaining disassembly and reassembly instructions. 5. Detach the diaphragm assembly from the bonnet and valve stem by turning the square of the valve stem in a clockwise (right hand) direction to remove the stem from the bonnet The diaphragm assembly may be detached by sliding the diaphragm stem head out of the slotted opening of the valve stem. Remove the backseat washer from the stem. Discard the diaphragm assembly, and backseat washer, and save the bonnet and stem assembly. B. Reassembly 1. Brush the threads of the bonnet with a wire brush to make the thread surfaces as clean as possible by removing old retaining compound and other foreign materials present which may prevent a tight seal. The female threads in the valve body from which the bonnet was removed cannot be cleaned satisfactorily with a wire brush. To remove the old compound, use a 1 1 /16"-18 NEF-2 thread tap (available from local sources). Care must be used in applying the tap so that it starts squarely in the body threads. If oil or grease is present on the body or bonnet threads, it should be removed with a suitable solvent. CAUTION: Do not scratch or mar seat area in valve body. 2a. If using repair kit 3100-80A, proceed to step 3. 2b. If using repair kit 3100-80B, place new backseat washer over stem and insert into bonnet. Slide the stem head of the new diaphragm assembly into the slotted opening of the valve stem of the bonnet and stem assembly. Turn the square of the valve stem counterclockwise until the diaphragm is almost touching the bottom of the bonnet.

3. At this point you will have either a completely new diaphragm, bonnet and stem assembly or a bonnet and stem assembly with a new backseat washer and diaphragm assembly. In either case, be sure the diaphragm is positioned so that it almost touches the bottom of the bonnet. This is accomplished by turning the valve stem. 4. Turn the square of the valve stem counterclockwise so that the diaphragm touches the bottom of the bonnet just enough to keep it in place. Add 1 /4 to 1 /2 counterclockwise turns to cup the diaphragm slightly. This is important as it positions the diaphragm properly so that when the valve is completelyassembled, the bonnet and body will grip the diaphragm properly and supply sufficient slack to permit the valve to open and close without undue strain on the diaphragm. 5. Carefully apply one 1 /8" strip of loctite around the bonnet threads approximately two threads up from the diaphragm end. Never apply loctite directly to the female body thread, because the bonnet will push the loctite ahead of it and come in contact with the diaphragm and result in damage to the diaphragm. NOTE: Do not allow loctite to contact the diaphragm or seat disc. 6. Install the diaphragm, bonnet and stem assembly into the valve body turning clockwise and tighten to 250 inch-lbs. torque. This torque is extremely important and therefore a torque wrench must be used. Allow loctite to dry. 7. It is advisable to spot check some of the bonnet body joints after the loctite has hardened for a period of at least 24 hours. Using a torque wrench, the torque necessary to break this seal must be at least 300 inch-lbs. If the seal can be broken at lower torque the parts were not properly cleaned or the loctite was not properly applied. This torque must be at least 300 inch-lbs. to assure that the bonnet does not loosen and come out in service, which would result in a hazardous condition that could result in fire and personal injury. 8. Reassemble handwheel to valve stem and secure with screw and washer. Tighten firmly with a screwdriver. Check valve for proper operation. 9. Turn handwheel fully clockwise to close valve. If valve was removed from the cylinder, reinstall the valve. 10. Pressurize cylinder. Check all seal points for leaks by applying a high quality leak detection solution. NOTICE LP-Gas is extremely flammable and explosive. Failure to install parts exactly as described in the instructions could result in a product that will not perform satisfactorily.
