Test Operation & Troubleshooting & Maintenance Picture Name Function It is used to prevent the pressure of circulation water from Safety Valve increasing unusually. When the pressure is larger than the set point (0.6MPa), this valve will open to relieve water pressure. It is used to expel air trapped inside the water system to make Exhaust Valve sure normal operation of the system. - Page 18 Test Operation & Troubleshooting & Maintenance Note: when vacuuming is finished, pressure inside the unit should be kept lower than 80Pa for at least 30 minutes to make sure there is no leak. Either charging valve 1 or charging valve 2 can be used for vacuuming.
