Carbon Replacement

MPS Replacement

The MPS cartridge incorporated in your Thermo Scientific TII is designed to prevent scale buildup
on the membrane(s). This cartridge must be replaced when the anti-scalant level is approximately
half dissolved. At this point, the quantity of anti-scalant entering the water is insufficient to
effectively prevent scale accumulation on the membrane(s). Before replacing the MPS cartridge,
ensure that all power and water are disconnected from the unit.

Carbon Replacement
The carbon filter incorporated in your Thermo Scientific TII provides a combination of filtration
and chlorine removal. There is a timer built into the Thermo Scientific TII which will alert you
when the carbon requires replacement. When the "Routine Care" light illuminates the carbon filter
may need to be replaced.
To find out the reason for the lit LED, choose MENU, scrolling to the "Routine Care" screen. Before
replacing the carbon filter, ensure that all power and water are disconnected from the unit.
