        Installation and calibration or relief valve
        Installation of the Adjustable Pressure Relief Valve is accomplished with tools readily available on the job site utilizing approved installation methods. Do not install outlet piping until relief pressure has been set. To set relief pressure, rotate adjustment cap clockwise until seated. Pressurize system to the pressure that you wish to provide relief Once system pressure has been set slowly turn pressure relief valve adjustment cap counter clockwise until the valve outlet starts to “spit” water from the system (bleed off pressure). Once the valve starts to “spit” then slowly close the valve cap until the valve stops “bleeding off” pressure. Check the system pressure gauge to make sure pressure is maintained at the relief pressure. Repeat steps until proper relief pressure has been set. Make sure to test setting by pressurizing system above relief setting to verify proper relief valve function.
