Page: 54 / 76

The frequency with which you will need to clean your unit and replace
your cartridge pack is dependent on your feed water’s characteristics, your
purity requirements and your usage. Clean your Thermo Scientific TII and
replace the cartridge pack when the product water purity drops below
acceptable levels of resistivity, when organic levels become too high, or if a
new 0.2 micron filter clogs rapidly after installation even though the
cartridge pack was thoroughly rinsed before the 0.2 micron filter was
installed.
The simple-to-use cleaning block is available (Catalog No. BK1403X2).
This is used to effect a complete cleaning.
1. Turn off the Thermo
Scientific TII and
disconnect it from the
power supply.
2. Open the right side door
(Figure 5-2).
3. Loosen the wing head screw
on the cartridge manifold.
4. Remove exhausted cartridge
pack by lifting the unit
manifold and pulling the
cartridge pack out.
