• Open the plug on the air vent located on the pump and
automatic air vents on the installation.
If the (CH.) pressure falls below 0.4 bar, the display will ash the
current pressure and the boiler will not operate. To increase the
pressure, the CH circuit requires " Topping up".
i
IMPORTANT:
When turning the 230Vac supply on to the boiler should
the water pressure be less than 0.5 bar an automatic air
vent function will be activated for a period of 5 minutes.
During this time the pressure should be increased and
air vented from the system. Note that the burner will not
re in either the CH or DHW mode and the display will
blink displaying the current water pressure.
• Vent air from each radiator until the water ows normally, then
close the vents.
• Leave the pump's air vent open.
i
IMPORTANT:
The following two operations will unblock the pump's
engine after a prolonged storage period and will purge
the air from the pumps circuit.
• Remove the screw from the pump shaft and introduce a at
screwdriver. A trickle of water, under no pressure should
normally come out of the pump.
• Rotate the pump's shaft through several turns, then replace
the screw.
