R middle of the NTF assy (10) to the sides, backwards and forwards
R and around the edges for a better bond.
R (h) Do the steps (3) (c) thru (g) until you have installed all of the

R (3) Preparation of Welding area:
R (Ref. Fig. 405/TASK 25-28-42-991-013)
R (a) Chamfer the edges of the NTF-covering at the joints with a
R TRIANGLE. Make a groove in the shape of a "V" with an angle of
R approximately 30 on the NTF edges. A stainless steel or
R aluminiuim flexible ruler will help to make a straight groove.
R CAUTION : DO NOT CAUSE DAMAGE TO THE MOISTURE BARRIER FOIL_______
