Here we have a guide for the ZeroPak Mini pro vac
Quick Start Guide
1: Preheating the machine: In cold conditions we recommend running the seal function once before processing the first bag, this ensures integrity of the first seal. Or switch to moist food setting for the first seal as this adds heat to the sealing bar
2: Making a bag from roll film: Place the end of the roll over the seal bar (the black sealing strip in the very front of the machine). Close the lid and lock it down by pressing on each front corner of the lid; then press the seal button. The seal button will illuminate to indicate the seal is active, and the pump will start to tighten the lid onto the roll. Once the seal light goes out and the pump stops the lid can be opened by pressing the grey buttons on each side.
The vacuum film can be cut to length either before this operation or while it is in progress.
3: Vacuum sealing a bag: Place the item to be vacuum sealed into the bag. Place the open end of the bag inside the vacuum chamber (the soft black neoprene seal). Close the lid and lock it down by pressing on each front corner of the lid, and press the vacuum/seal button. Once the vacuum process is complete the seal light will come on. Do not open the lid until the seal light goes out. The lid can now be opened using the grey buttons on each side
4: Manual seal for soft foods: To prevent crushing of soft foods the machine can be operated manually. Once the vacuum process has started (see above instructions) wait until the desired vacuum pressure is reached, then press the seal button. The pump will stop and the seal will activate. Once the seal light goes out the lid can be opened. Inspect the seal. If the seal does not show as a constant clear line, place another seal across the top of the bag in the manner described for making the bag.
1: When vacuum sealing anything with a liquid content, place the bag in a freezer for a short time to semi freeze the liquid.
The bag can now be vacuum sealed without risk of sucking liquid into the seal area.
2: Switch from Dry to Moist setting when doing liquids. This adds more heat to the seal bar
3: Switch from Normal to Gentle when doing soft foods. This slows the vacuum down to gain more control
2: The vacuum seal process can be stopped at any time by pressing the red "STOP" button.
1: The machine does not automatically switch from vacuum to seal:
There is an air leak in the bag. Check the first seal, or there is a crease in the film where it enters the vacuum chamber, usually caused by over filling the bag.
2: The vacuum sealed bag does not maintain its vacuum:
Usually caused by food or liquid contamination in the seal area. Inspect the seal after the vacuum sealing. If there is evidence of contamination place another seal across the top of the bag. Also inspect both top and bottom seals. They should show as a constant clear line across the full width of the bag. The bag also may have been damaged after being sealed
