4. Measure 50.8 mm (2 in) from the mark on the evaporator tube (2) towards the evaporator from the previous step.
IMPORTANT: Do not allow metal burrs to enter the evaporator tube (2) during cutting or when removing the burrs.
5. Using a tubing cutter, cut the marked section of the evaporator tube (2).
6. Remove the burrs from the evaporator tube (2).
