your new sprayer. It is used to evacuate

FlexLiner.

5. Open VacuValve cap. Tilt the sprayer so
the VacuValve is the highest point,
causing any air in the FlexLiner to rise to
the VacuValve. Gently squeeze the
FlexLiner to evacuate all air through the
VacuValve air hole. Once you see
material enter the VacuValve reservoir,
all air should be evacuated from the
FlexLiner.
