NOTICE

Filter cartridges should be changed at end of filter life, due to lack of 

filtering performance, or whenever a 15 psi pressure drop or greater 

is experienced during normal operation, whichever comes first .
For all replacement filters and components contact your authorized 

Hydro-Safe Foodservice representative .
*The QTCM15S, QTCM20S and QTCMX20S are the same filters as the 

QTCM15, QTCM20 and QTCMX20 respectively . Only the label position has 

been changed so that the label faces forward on single cartridge systems .

NOTICE

Cartridge capacities are estimates and may be less depending on 

incoming water quality .

Notice to Installer
