Similar to a QC7i-MC single system, EV927501, except we have added an E20 prefilter to the manifold.
There are three replacement cartridges for this system:
EV961255 - MC cartridge - this is the cartridge that comes with the system
EV961310 - XC cartridge - this is an upgrade from the MC cartridge
EV953426 - EC210 - sediment prefilter
