Ben – Welcome aboard!!!
You should have received a sample bag in your shipment which was meant to be used for testing and getting to know how your sealer will act with the thinner Drybag material. Please test several times and don’t get upset with your first seal if it doesn’t work right! I must have practiced on my first bag 6 or 7 times. I’m not familiar with your model 2340, but I know that Food Saver changes model numbers about as often as most people change their shorts! You didn’t mention having purchased a sealing strip called a Vac-mouse which makes using a FS with a Drybag much easier. OTOH here is a YouTube 5 minute instruction video I made to do the trick. This was done on a model 2240, but I just imagine it is quite similar to your 2340. BTW I have an older model 1050 and FS hasn’t changed a whole lot over the years!
Feel free to ask questions! Ron
