The cylinder is a wearing part of your steam generator and an expensive spare part. In order to optimize the lifespan of your cylinder, we advice a regular maintenance. The water does not have the same amount of minerals identical everywhere. Indeed, it is not easy to define a determinate operating period between two maintenances. A first  inspection after 50 hours of operation is prescribed in order to determinate more precisely the maintenance frequency of the cylinder. If a white deposit begins to form on the cylinder electrodes, you might need to proceed to more regular maintenances. On the contrary, if your cylinder is clean, you can space out your maintenances. Example : If the use of Barriclean is twice a year, the maintenance of your cylinder is recommended at the end of each using period. Disassemble the cylinder is quite an easy operation : - Release carefully the electrodes’ caps. - Loosen the hose clip and unplug the steam hose - Raise the tank out of its base on the supplying collector / drain of the device - Clean or replace the used tank - The repositioning of the tank has to be done opposite to the positioning (be careful to replace the electrodes’ caps in the same order)
