* 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
It is important the pump is properly vented and spinning freely.
The boiler must be disconnected from the mains.
Be careful not to splash any of the electrical components.
Carefully unscrew the cap in the pump centre whilst protecting
the electrics from any water that is released. Using a suitable
screwdriver rotate the exposed spindle and replace the cap.
NOTE: 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.
