generally exposed to wear. Over time, the surface transforms and
gray-colored zones initially appear; without undertaking any
maintenance, this could lead to tank corrosion.
To extend tank durability, you are advised to heed the following
indications:
On a regular basis, remove metal particles from the tank
and clean all traces of rust.
Only apply appropriate chemical products.
Change the liquid solution at regular intervals.
Do not leave the device running idly, be sure to turn it off
