Filter Cartridge Life Span
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 .
Filter Placement Reference
The replacement filter cartridges are to be installed from left to right, in
any given system, as they appear in the above chart from top to bot-
tom respectively .
Example: Cube Max-S3 will have a HSR-S-SED-5M in the left hous-
ing, a CBMXR-S-CB in the middle housing and a DOR-OF110RM in
the right housing .
Please note:
Cartridge capacities are estimates and may be less
depending on incoming water quality .
