* The standard configuration of the boiler only allows a maximum of 12kW when connected SINGLE-PHASE
230V – 50Hz.
5.2 HEATING SYSTEM INITIAL FILLING
Ensure both flow and return isolation valves are open. Identify the boiler automatic air release valve at the top right
hand side of boiler and loosen the cap. Close any manual air vents fitted on the system.
Be careful not to splash any of the electrical components.
Connect the filling loop and fill slowly until the pressure gauge indicates between 1 and 1.5 bar.
Proceed to vent all the manual release valves until all air is purged from the system. It will be necessary to top-up
through the filling loop during this operation.
5.3 PUMP CHECKING & VENTING
Sometimes (i.e. if display fault E3) it is necessary to check that the pump is properly vented and spinning freely.
To purge the pump, turn on the boiler and with the pump selector, alternate between positions III and Min every
fifteen seconds. Keep this operation for 5 minutes.
If excess air remains in the system or there is insufficient pressure or flow rate the boiler will fail to operate and
display fault E3.
A LED indicator informs about the operating status of the pump:
Green: correct operation.
-
Green / red flashing: Lower voltage U<180V; overvoltage U>253V; Module overheating
-
Red flashing: pump blocked.
