Initial operating and filling procedures.
Check the water pressure on the display regularly and make sure
that the figure is between 0.6 and1.5 bar when the system is cold.
If the pressure is just under the minimum value the display will
request a the boiler be refilled.
To re-pressurise the boiler, it will be necessary to connect
the silver flexible hose supplied to the two isolating points
underneath the boiler, once the hose is connected, open up both
of the black quarter turn handles, once the pressure reads 1.5 bar
on the display, close both handles and disconnect the hose .
If the pressure drops very frequently, there may be a water leak
at some point in the system. If this is the case please contact your
installer and ask them to check it.
