5.5 Installing a water meter

BWT recommends the installation of a water meter in the inlet of the filter cartridge in case
the filter system is used for a device without an integrated water meter (e.g. coffee machine)
which indicates the required replacement of the filter cartridge. With the water meter the filter
cartridge's residual capacity can be determined at any time. Observe the operating instructions
of the BWT .
