9.2 Maintenance frame work Mineral deposits precipitate and crystallize very differently in different types of water, even when two types have the same conduc- tivity and hardness levels (the various con- stituents in the water interact differently). Instructions on maintenance and cleaning intervals, or on electrode service life, are based entirely on empirical data.

Dismantling Once the steam humidifier will no longer be used, dismantle (demolish or scrap) it by fol- lowing the installation procedures in reverse order. WARNING Dismantling of the unit may only be per- formed by qualified personnel. Electrical dis- mantling may only be performed by trained electricians.
