    8. Pressure Vessel 8. Pressure Vessel The pressure vessel supplied as part of your Dutypoint product is used to absorb and conserve the potential energy of pressurised liquid. Stored energy from liquid under pressure is transferred to the water system when required.
  • Page 53 8. Pressure Vessel e.g: If the maximum pressure generated by the pump in a system is 6 bar, this will require a pre-charge pressure of 6 × 90% = 5.4 bar. To verify the pre-charge pressure: First check that the expansion or pressure tank is totally drained of water and isolated. Refer to Figure 8.20: Pre-Charging a Pressure Vessel (p.
  • Page 54 8. Pressure Vessel Set the pre-charge pressure, using the procedure earlier in this section. Ensure that the pressure does not exceed the value specified in the procedure. The appliance must be supplied with efficient and sufficient safety and control facilities, in particular the safety valve must be connected to the appliance and be free from interference and must be gauged to the quantity of fluid to be discharged.
