Do not unsolder a defective component. Cut it out of
the system. Do not remove the pinch-off tool until the
new component is securely in place.
3. Cut the tubing of the defective component with a
small tubing cutter.
4. Solder the replacement component in place. Allow
the solder joint to cool.
5. Remove the pinch-off tool.
6. Re-round the tubing. Position the flattened tubing in
the proper hole in the pinch off tool. Tighten the wing
nuts until the block is tight and the tubing is rounded.
NOTE: The pressure controls will operate normally once
the tubing is re-rounded. Tubing may not re-round 100%.
