the settings menu.)

ready or the air/water pump is already installed). When the compressor
is started for the first time, it is automatically checked that it is running in
the correct direction. An error message is displayed in the panel display
if it is rotating in the wrong direction. Switch any two phases to change
the direction of rotation. Use your hand to feel that the hot gas pipe
