System low pressure (replenishment)

Sime ESTELLE HE B4 INOX ErP boilers are NOT equipped with a
system filling device. The system must be fitted with a pressure
gauge (A), to check that the (cold) water pressure is between 1
and 1.2 bar (98–117.6 kPa)
When the system water pressure indicated on the pressure
gauge (A) falls below 1 bar (98 kPa) , the unit must be filled.
To do this:
– open the filling valve (B) to raise the pressure until it reaches
the correct value, between 1 and 1.2 bar (98–117.6 kPa)
– close the valve (B)
