Warning
: no relation can be demonstrated between water hardness and conductivity.
IMPORTANT WARNING
: do not treat water with softeners! This could cause corrosion of the electrodes or the formation of
foam, leading to potential operating problems or failures.
Avoid:
1. using well water, industrial water or water drawn from cooling circuits; in general, avoid using potentially contaminated water,
either from a chemical or bacteriological point of view;
2. adding disinfectants or corrosion inhibiters to water, as these substances are potentially irritant.
2.8 Drain water
Inside the humidifier the water boils and is transformed into steam, without the addition of any substances. The drain water, as a
result, contains the same substances that are dissolved in the supply water, yet in greater quantities, depending on the concentration
in the supply water and the set draining cycles, and
may reach temperatures of 100°C . Not being toxic, it may be drained into the
sewage system. The drain connector has an external diameter of 32 mm.
