2. Check if by-pass is locked properly (if existent).
3. Activate current supply and press the ON/OFF switch on the control panel for at least 1 second.
4. Wait 5 to 10 minutes until machine has achieved its standard operating parameters.
5. Slowly open the air outlet valve and successively open the air inlet valve.
6. If existent, close the by-pass.
