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 .
