System Set-Up
Flow Restrictor Removal, Adjustment, and Replacement
1. Locate the yellow concentrate tubing (Fig. B). 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. C). 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 plug 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 membrane that you have. Find the
product
water flow rate
in the left-hand column and the
length of the flow restric-
tor
in the right-hand column.
Example: If your Flow Restrictor Assembly is for a 90 GPD Membrane and
the product water flow rate is 175 mL/Min, then the flow restrictor
length should be 6 inches (15.2 cm)
4. Using a new single-edge razor blade, carefully measure and then cut the
flow restrictor to the 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.

Deionization Cartridge Diagnostic
The DI stage is an anion cartridge #DI-SB-CC-10. In order to deter-
mine the condition of the 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.
Failure to replace the DI
cartridge upon exhaustion will contaminate the product water.
(For “down flow” DI systems or systems that incorporate a permeate
pump, the color will change from the top to the bottom ).
Note: If the pH of your tap water is too high, the resin may not
change color.

Deionization Cartridge Replacement
Materials Needed:
One DI-SB-CC-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 tighten with the wrench.
6. Turn on system and check for leaks.
