I - GUIDELINES FOR SELECTION AND INSTALLATION OF PRESSURE REDUCING VALVE                       Pressure relief valve must be installed with water in vertical direction arrow on the valve body (C). For more safety and longevity of the pressure reducing valve, we recommend fitting a filter before the pressure relief valve to remove sediment that may be in the water. If the water and sediment will affect the valve disc and make incorrect valve operation.   Pressure reducing valve mode preset outlet pressure is 3 bar. In case of need to change the output settings to comply with the following guidelines: - Before adjusting the output pressure must close all valves, taps installed after the pressure relief valve. - To reduce the output pressure of the pressure relief valve, you remove the cap (A) and loosen the screw (rotate counterclockwise direction). - To increase the output pressure of the pressure relief valve, you remove the cap (A) and tighten the screws on (rotate clockwise direction down).   Note: To help them adjust to the pressure where the easy, you should unscrew the plastic (F) on the valve body and insert a pressure gauge on it. When looking at the pressure gauge, you will be easier to adjust output pressure to the desired level.
