FLOW RESTRICTOR REMOVAL, ADJUSTMENT & REPLACEMENT
1. Locate the yellow concentrate tubing (Fig. B) (for Dual-Membrane System
Fig. C).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. D). 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 collar 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. A). 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
otherwise damage the end of the capillary tubing protruding from the end
of the insert.
