4.
Wrap tube and heat trace with 1 pass of refl ective
tape (25% overlap), then wrap with 3 passes of
glass fi ber tape (50% overlap), or until fi ber tape
is equal to original bundle insulation thickness.
2.
Cut 38mm (1.5”) off the end of the tubing and make
tube fi tting connections with appropriate fi ttings,
provided by others. If no electrical heat trace is
present, go to Step 5.
5.
Complete with additional passes of heat refl ective
tape.
1.
Remove outer jacket and insulation from tubing
bundle approximately 127 mm (5”) from end of the
