MANUAL OPERATOR TIPS AND GUIDELINES
1. Set appropriate temperature on vacuum machine and hot water tunnel.
2. Place opening of bag over sealing bar. Examine that there are no wrinkles over the sealing area to avoid subsequent leakages.
3. Ensure the product has not been pressed at the bottom of the bag, and the area of the seal is completely clean and seal itself is not burnt. Check Teflon tape regularly to minimize seal burns.
4. Leave at least 5cm spacing between product and vacuum seal. This is to improve vacuum effect, and also to allow some room for product to expand (particularly for products that will be stored frozen)
