(The actual reading on the pressure gauge should
ideally be 0.5 bar plus an additional pressure
corresponding to the highest point of the system above
the base of the boiler - 10 m head equals an additional 1
bar reading on the pressure gauge. The minimum
pressure should not be less than 1 bar in any
installation.)
If the system is to be treated with an inhibitor it should
be applied at this stage in accordance with the
manufacturers instructions.
