• Open the drainage valve using the manual drainage switch (black round
button) located on the electronic print; the cylinder then empties itself
completely.
Let the cylinder cool down.
• Before proceeding further, disconnect the unit from the mains.
• Loosen the clamp on the steam hose, pull off the hose and remove
the electrical plug from the cylinder; the cylinder itself can now be
removed.
• To fit the new unit, reverse the above procedure. It is advisable to
wet slightly either the O-ring seal on the drainer or the outside of the
cylinder’s drainage aperture, since this makes it easier to fit the new
cylinder.
The humidifier is re-started in accordance with the recommendations
detailed in the chapter entitled “Putting the humidifier into operation”.
All NORDMANN steam cylinders are fitted with a removable drainage
strainer which can be extracted easily for cleaning.
The cylinder can then be put back into place and the humidifier put back
into operation.
