English EVRM-NA SAFETY SOLENOID VALVE 100% TESTED TWO YEARS WARRANTY The EVRM-NA type valve is a manual reset safety valve that is normally open. A manual operation is therefore necessary to open the valve and set the mechanism consenting to maintain this state. The powering by means of line current and/or condenser discharge, induced by the leakage detector, causes tripping of the mechanism and consequent closing of the gas passage. If energizing of the sensor persists due to the presence of gas, the valve remains under power and does not allow reset. When the causes for locking have been eliminated, the valve may be reopened by working it manually. This type of device, connected with one or more leakage detectors or alarm signals for the presence of carbon monoxide, is suitable for performing locking operations on the gas line. INSTALLATION AND ADJUSTMENT Check correspondence of flow direction with arrow printed on valve body, check correct alignment of connecting pipes. Valve may be mounted with coil in horizontal or vertical position. Coil may be oriented 60 degrees in any direction. Install in an area that is protected from rain and water splashes or drops. For electrical connection remove cap on the DIN plug and connect power cables to rectifier circuit clamps. CLEANING AND MAINTENANCE Dust and any foreign bodies may be easily removed from the filter or the gas passage zone. After shutting off upstream gas and electric current, the coil is removed by unscrewing the reset knob and the knurled fastening cap. Unscrew the 4 screws fixing the counter flange to valve body. During this operation care should be taken not to cause damage to the seat. Avoid dissembling or tampering with the reset mechanism.
