Page 11: Notes For Using Pressure Maintenance Systems
If the pressure is too high, air is released by means of a solenoid valve. The systems are built solely with closed-diaphragm expansion tanks to prevent the damaging introduction of oxygen into the heating water. Installation Instructions PE1c Pellet 16-22 | M2130721_en... -
Page 12: Use With Storage Tank
Design Information Use with storage tank Pump-controlled pressure maintenance A pump-controlled pressure maintenance unit essentially consists of a pressure- maintenance pump, relief valve and an unpressurised receiving tank. The valve releases hot water into the receiving tank if the pressure is too high. If the pressure drops below a preset value, the pump draws water from the receiving tank and feeds it back into the heating system. -
