FLOW RESTRICTOR REMOVAL, ADJUSTMENT & REPLACEMENT
1. Locate the yellow concentrate tubing (Fig. B ). Remove tubing from its push-fitting:
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 coller and thin capillary tubing) may then be gently extracted.
Note: Sometimes, the Flow Restrictor might get stuck in the membrane fitting.
To remove, use needle nose plyers and rock the collar back and forth, while
pulling. 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-most column and the length of the flow restrictor in the
right-most column.
Example: If your Flow Restrictor Assembly is for a 90 GPD Membrane and
the product flow rate is 175 mL/min, then the flow restrictor length should
be a total of 6 inches (15.2 cm).
