The left side of the table shows the reduced water hardness, derived from the mains water
hardness. The right side of the table shows the expected lifespan of the cartridge, derived
from the mains water hardness and the type of Quooker tank used. For continuous optimum
performance replace the cartridge at the end of the lifespan.
Enter the replacement date for the cartridge in the table below. Keeping this table in a handy
place will remind you to order a new cartridge on time.
For Quooker systems installed after October 2017, the life of the cartridge is determined
by the Scale Control Plus Meter. This sounds an alarm signal when the cartridge needs to
be replaced. Part E describes how to install this meter.
