INSTALLATION I The Easy Risers Swing Check Valve must be installed in an area not subject to freezing temperatures or physical damage. When corrosive atmospheres and/or contaminated water supplies are present, it is the owner's responsibility to verify compatibility with the Easy Riser's Swing Check Valve, trim, and associated equipment. Prior to installing the valve, thoroughly flush the water supply piping to verify that no foreign matter is present. The Easy Riser's Swing Check Valve may be installed in the vertical position with direction of flow up, or in the horizontal position E with the access cover up. 1. Remove all plastic thread protectors from the openings of the Easy Riser'a Swing Check Valve. 2.Apply a small amount of pipe-joint compound or tape to the external threads of all pipe connections required.Take care not to allow r any compound, tape, or other foreign matter inside any of the nipples or openings of the valve or trim components. 3. Easy Riser"Swing Check Valve Trim Charts are provided with Trim Packages and on the Viking websile. € 4. Verify that all system components are rated for the water working pressure of the system. f Hydrostatic Test: The Easy Riser`s Swing Check Valve is manufactured and listed for use at a maximum water working pressure of 300 psi (20.7 bar). The valve is factory tested at 600 psi(41.4 bar). Easy Riser's Swing Check Valves may be hydrostatically tested at 350 psi(24.1 bar) and/or 50 psi(3.5 bar)above the normal water working pressure for limited periods of time(two hours)for the purpose of acceptance by the Authority Having Jurisdiction. If air testing is required, DO NOT exceed 40 psi (2.8 bar) air pressure. 5. OPERATION (Refer to Figure 1.) Water flowing through the Viking Easy Riser® Swing Check Valve lifts the rubber-gasketed clapper (8 and 9) off the seat (12) and flows into the sprinkler piping. When flow through the valve stops, the clapper(8)closes quickly.The rubber gasket (9)forms a tight seat against the brass water seat(12), trapping pressurized water above the clapper and preventing reverse flow from the sprinkler piping. 6. INSPECTIONS, TESTS, AND MAINTENANCE 0 The owner is responsible for maintaining the fire protection system and devices in proper operating condition. The Viking Easy Risers Swing Check Valve and trim must be kept free of foreign matter,freezing conditions, corrosive atmospheres, contaminated water supplies, and any condition that could impair its operation or damage the device. It is imperative that the system be inspected and tested on a regular basis. The frequency of the inspections may vary due to con- taminated water supplies, corrosive water supplies, and corrosive atmospheres. For minimum maintenance and inspection require- ments, refer to NFPA 25. In addition, the Authority Having Jurisdiction may have additional maintenance, testing, and inspection requirements that must be followed. Any system maintenance that involves placing a control valve or detection system out of service may eliminate the fire protection capabilities of that system. Prior to proceeding, notify all Authorities Having Jurisdiction. Consideration should be given to employment of a fire patrol in the affected areas. 6-A. Five-Year Internal Inspection Internal inspection of check valves is recommended every five years unless inspections and tests indicate more frequent inspec- tions are required. (Refer to Figure 1.) 1. Notify the Authority Having Jurisdiction, remote station alarm monitors, and those in the area affected that the systern will be taken out of service. Consideration should be given to employment of a fire patrol in the affected areas. 2. Close the water supply main control valve, placing the system out of service. 3. Open the main drain. If necessary, open the systern test valve to vent and completely drain the system. 4. Use the appropriate wrench to loosen and remove cover screws (14), and remove cover and clapper assembly (2-11). 5. Inspect water seat(12). Wipe away all contaminants, dirt, and mineral deposits. DO NOT use solvents or abrasives. 6. Inspect cover and clapper assembly (2-11) and cover gasket (13). Test the hinged clapper (8) for freedom of movement.
