* 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.
*** 255 being already equipped with an Aircheck, the safety brine valve should not be equipped
with and aircheck too otherwise this may create hydraulic interferences and cause brine draw
malfunction due to safety brine valve aircheck not opening.
**** Wear part.
