Pressure Expansion Vessel; Pump Capacity Diagrams, Heating Water Side; Brine Capacity Diagram, Collector Side - Nibe FIGHTER 1310 Installation And Maintenance Instructions Manual

The brine circuit should be fitted with a pressure
expansion vessel. If there is a level vessel this should
be replaced. The brine side should be pressurised to
at least 0.5 bar.
The pressure expansion vessel should be dimen-
sioned as set out in the diagram, to prevent operating
disturbances. The pressure expansion vessel covers
the temperature range from -10 °C to +20 °C at a pre-
pressure of 0.5 bar and the safety valve's opening
pressure 3 bar.
