1.2 SYSTEM PRESSURE GAUGE
The normal operating water pressure is shown when the
needle is in the GREEN section of the gauge between 1 and 2
bar.
If the pressure drops too low the system will need topping up
via the filling loop.
If the pressure exceeds 3 bar the pressure relief valve will
operate and a fault may be indicated. Contact your installer
(see section 1.9).
