10.1. Commissioning, Filling Water into Boiler and Heater Installation
- First of all, the electrical connection of the boiler is done. The electrical connection of the device must be
connected to a grounded power supply line that can supply enough voltage (230 VAC, 50 Hz) for the device.
- All radiator valves should be opened.
- CH flow and CH return of boiler should be opened. Check them.
- After all these processes, filling valve is slowly opened and filling procedure is initiated.
The filling process continues until the water pressure of 1.5-2 bar is seen on the LCD display and then the filling
valve is closed.
- When the water pressure increase to 0.8 bar, the LCD will show "AP" and the boiler will switch to automatic
air vent mode. In this case you should definitely wait for 160 seconds without pressing "RESET".
- Check water pressure on pressure indicator frequently and ensure that the pressure is between 1.5 and 2
bar when system is cold. If the pressure drops frequently, it means that there is a water leak in the system. In
such case, it is necessary to call a plumber.
