Before removing the magnesium stick, drain the water tank by following drainage operations.
2)
Open the cap on the mounting mouth for the magnesium stick in the water tank.
3)
Use a hex key to unscrew the magnesium stick component, and then steadily removed the
magnesium stick to prevent it from falling into the inner container of the water tank.
4)
Install a new magnesium stick component into the mounting mouth of the magnesium stick, and
then tighten it using a hex key.
