INSTALLATION The Model J-1 Alarm Check Valve must be installed in an area not subject to freezing temperatures or physical damage. When corro- sive atmospheres and/or contaminated water supplies are present, it is the owner's responsibility to verify compatibility with the Model J-1 Alarm 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 Model J-1 Alarm Check Valve may be installed in the vertical position with direction of flow up, or in the horizontal position with the access cover up. 1. Verify that the appropriate trim chart and technical data for the Alarm Check Valve and associated equipment are available. 2. Remove all plastic thread protectors from the openings of the Alarm Check Valve. 3. Apply a small amount of pipe -joint compound or tape to the external threads of all pipe connections required. Take care not to allow any compound, tape, or other foreign matter inside any nipples or openings of the valve or trim components. 4. Install the Model J-1 Alarm Check Valve and trim according to current Viking Trim Charts for the valve used. Trim charts are provided with trim package and can be found on the Viking website. 5. Verify that all system components are rated for the water working pressure of the system. Placing the System in Service When the wet -pipe system is ready to be placed in service, verify that all equipment is adequately heated and protected to prevent freezing and physical damage. NOTE: FOR PROPER OPERATION OF THE WET SYSTEM AND TO MINIMIZE UNWANTED (FALSE) ALARMS, IT IS IMPORTANT TO REMOVE TRAPPED AIR FROM THE SYSTEM WHEN FILLING IT WITH WATER. AIR TRAPPED IN THE SYSTEM MAY ALSO CAUSE INTERMITTENT OPERATION OF THE WATER MOTOR ALARM DURING A SUSTAINED FLOW OF WATER (SUCH AS THE FLOW REQUIRED BY AN OPEN SPRINKLER OR THE SYSTEM TEST VALVE). CONSIDER INSTALLATION OF AUXILIARY VENTS TO FACILITATE VENTING. A CAUTION Opening of the water supply main control valve will result in water flow from any openings in the system. 1. Verify that auxiliary drains are closed and that the system is free of leaks. 2. Open the system test valve (and any auxiliary vents provided to facilitate removal of air from the system) to allow air to escape from the system while it is filling with water. 3. If desired, close the alarm shut-off valve to prevent local alarms from operating while filling the system. NOTE: ALARMS AND ELECTRIC PANELS CONTROLLED BYAN ALARM PRESSURE SWITCH INSTALLED IN THE "ELECTRIC ALARM PANEL" CONNECTION PROVIDED IN THE TRIM CANNOT BE INTERRUPTED. (SEE TRIM CHART.) 4. Slowly open the water supply main control valve. 5. Allow the system to completely fill with water. Allow water to flow from the system test valve, and any other open vents provided, until all air is exhausted from the system. 6. After all air is exhausted from the system, close the system test valve and all other open vents. 7. The pressure gauge on the system side of the Alarm Check Valve Clapper should indicate water pressure equal to or greater than the water pressure indicated on the gauge located on the supply side of the clapper.
