* Wear parts - durability strongly affected by raw water quality and regeneration frequency.
** Electronic parts – durability strongly affected by power source quality and stability.
*** Elastomer durability is strongly affected by raw water concentration in chlorine and its derivative.
**** Seals & Spacer cartridge is equipped with O-rings that ensure watertightness by compression, therefore by unmounting/
remounting the same cartridge may cause it not to be watertight anymore, each time the seals & and spacer cartridge is
extracted from the valve body it must be pre-placed by a new one. Note that extraction the piston may also extract the Seals
and spacer cartridge at the same time for this reason it not advised to unmount the piston, clean and lubricate it with silicon
grease as with former residential fleck valves for the regular maintenance, but only to replace it at least every 3 years.
