Poly-Tex Poly-Vent (Retrofit) - Manual (Page 23)

IMPORTANT:
This drawing illustrates end views of the
Poly-Vent. When inflated, the Poly-Vent tubing
seals will form a "zig-zag" profile. If you have
one tube that is bulging, check your zig-zag
pattern by inserting your hand in between the
poly tubes. You will notice one row of seals are
towards the inside, one row towards the outside,
then inside, etc. (see Figure A).
To fix the bulge, simply force the bulge inward
with your hand the full length of the vent (Figure
B).
