DEIONIZATION CARTRIDGE #2 REPLACEMENT
(Right-most housing)
The last stage is a dual layer cation/anion cartridge, or in some cases a
mixed bed DI. The condition of this cartridge should be judged by observ-
ing either a RED or GREEN light indication from the monitor.
Please note
that the probe is located after housing #4. Thus, the monitor indicates
the condition of the final DI stage cartridge only.
Turn the on the system and allow water to flow past the monitor probe
for at least 20 minutes before attempting to use the monitor. The monitor
will indicate GREEN when the cartridge is in good condition and RED if it
is exhausted and in need of replacement. (Be sure that switch #7 is in the
ON position and all other switches are OFF.)
Replace the third stage cartridge
immediately
if the RED light is on.
Note: In addition to the monitor indicating the DI cartridge condition, the
resin will also change color. Note that only the DI-AR-DI-10 cartridge is
color indicating, not the lab grade mixed bed cartridge.
The DI-AR-CI-10 cartridge’s violet-colored layer is the resin layer used to indi-
cate exhaustion and will change to an orange color when exhausted. The
standard cartridge will change color from bottom to top while the “down-
flow” version will change from top to bottom.
The color change that occurs in this stage gives a general indication of its
condition but the monitor will provide the most accurate diagnosis of its
condition. There may be local conditions that affect the color-changing
characteristics of these DI cartridges. High pH water may prevent these car-
tridges from changing colors.
Materials Needed:
One DI-AR-DI-10 Deionizaton cartridge or (DI-MB-10,
filter
wrench.
Procedure:
1. Follow the procedure for Cartridge #1 Replacement.
