general.
If users need to set the embedded filter reducer, the machine

Ensure the mains supply is disconnected whilst
removing the cover.
Reconnect the mains supply but take care to avoid any
contact with live electrical components.
Switch on the machine.
Start the gas flow
Lift the pressure control knob upward.
Adjust the gas pressure to the desired value by rotating the
knob (rotate to “+” direction to increase gas pressure; rotate
to “-” direction to reduce gas pressure).
Press down the pressure control knob to lock the adjusting
knob.
Any water will be drained automatically via the auto-drain
function in the embedded filter reducer.
Ensure the mains supply is disconnected whilst
replacing the cover.
