Warm Tips:
1.Slide the sealing clip along the zipper track 3–4 times to ensure full closure.
2.Open the blue turbine valve cover, then attach the vacuum cleaner nozzle directly to the valve/ or rotate the hand pump clockwise to tighten. Do not remove the pink air cushion.
3.Close the blue cover immediately after air evacuation is complete.
4.Verify that both the zipper and blue valve cover are completely sealed, and check for any hissing sound indicating air leakage.
Reminder:
1.When using a manual pump, first rotate it clockwise to tighten, then begin vacuum pumping.
2.Manual pressure or by knees to release some air, then using the hand pump can increase efficiency by up to 40%.
