Increase preliminary filling pressure

If – over the course of time – the pump starts up after just a slight removal of water (approx. 0.5 l),
the preliminary filling pressure in the boiler must be re-established.
1. Disconnect the mains plug.
2. Open pressure line (turn on water spigot or nozzle), allow water to completely run off.
3. Unscrew plastic butterfly valve (9) on the front side of the boiler; the air-control valve is
located behind it.
4. Attach air pump or compressor hose to the air-control valve with a "tire valve" connection and
pressure gauge.
5. Pump up [inflate] to the designated preliminary filling pressure (preliminary filling pressure:
1.8~2.0 bar).
6. Reconnect the device and check function.
