DEIONIZATION CARTRIDGE #1 REPLACEMENT
( Second housing from the right )
The first DI stage is an anion cartridge DI-SF-CI-10. In order to determine
the condition of this cartridge, watch for the color to change from the
bottom to the top. The color will change from a very dark blue to a
lighter blue or tan color. Once the cartridge has changed color by 70 to
80% it must be replaced in accordance with the following instructions.
(For "down flow" DI systems or systems that incorporate a permeate
pump, the color will change from the top to the bottom ).There may be
local conditions that affect the color-changing characteristics of this DI
cartridge. High pH water (due to soda lime softening) may prevent this
cartridge from changing colors.
Materials Needed: One DI-SF-CI-10 Deionizaton cartridge, filter wrench.
Procedure:
1. Remove the filter housing from its cap by unscrewing it counter
clockwise as viewed from the bottom.
2. Remove and discard the old cartridge from the housing.
3. Thoroughly wash out the housings with hot soapy water to
which a few teaspoons of household bleach have been added.
Rinse well with clean hot water.
4. Install the new deionization cartridge. Make sure the cartridge is
installed in the correct direction as marked on the filter housing
and that the top seal is securely attached to the top of the
cartridge
5. Re-install the bottom housing onto the cap by rotating it clock-
wise and hand tighten ONLY.
6. Turn on system and check for leaks.

FLOW RESTRICTOR REMOVAL, ADJUSTMENT
AND REPLACEMENT
1. Locate the yellow concentrate tubing (Fig. E ). Remove the tubing from its push-fitting
at the membrane as follows:
a.) Firmly depress and hold the push-fitting collar down with your
thumbnail.
b.) While the push-fitting collar is depressed, pull the tubing straight
out of the push-fitting. Once the tubing is removed, release the collar.
2. Carefully remove the flow restrictor assembly, now visible as a plastic insert In the end
of the yellow tubing (Fig. F). You may use an object such as a dull knife to help pry the
flow restrictor insert from the end of the tubing. The entire flow restrictor (consisting
of the insert coller and thin capillary tubing) may then be gently extracted.
Note: Take care not to crush or otherwise damage the delicate capillary tubing.
3. Refer to the Flow Restrictor Tables (Fig. D). Find the table that represents the
Flow Restrictor Assembly for the system that you have. Find the product
flow rate in the left-hand column and the length of the flow restrictor in the right-
hand column.
Example: If your Flow Restrictor Assembly is for a 90 GPD Membrane and
the product flow rate is 170 mL/Min, then the flow restrictor length should
be cut to 6.5 inches (16.5 mm). 170 is about halfway between 164 (7 in.)
and 175 (6 in.).
4. Using a new single-edge razor blade, carefully measure and then cut the
flow restrictor to the total length indicated.
5. Re-insert the flow restrictor assembly into the yellow tubing and firmly
re-seat the insert into the end of the yellow tubing by carefully pressing on
the insert with your thumbnail. Care should be taken not to crush or other-
wise damage the end of the capillary tubing protruding from the end of
the insert.
