Instruction manual

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 Barnstead 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 Barnstead 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.
5. Clean the system per the
instructions in System
Cleaning Procedure of this
manual.

according to the instructions in the “Installation” section.
7. Reset the cartridge pack timer by following the “Timers” section of this
