Maintenance and Servicing
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.
1. Open the front left door (Figure 5-1).
2. Remove the MPS cartridge by pressing
the upper and lower thumb buttons on
the quick disconnect fittings.
3. Remove the MPS cartridge by pulling
the cartridge straight out.
4. Replace the MPS cartridge by following
the instructions located in the “MPS
Cartridge Installation” section of this
manual.
The carbon filter incorporated in your Thermo Scientific TII provides a
combination of filtration and chlorine removal. There is a timer built into
the 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.
1. Open the front left door (Figure 5-1).
2. Remove the carbon filter by first pressing the upper and lower thumb
buttons on the quick disconnect fittings.
3. Remove the carbon filter by pulling the cartridge straight out.
4. Replace the carbon filter by following the instructions located in the
“Carbon Filter Installation” section of this manual.
