Initial Testing Of Bag Seal - Weston PRO-3500 Instructions

INITIAL TESTING OF THE BAG SEAL
Test seal a couple of vacuum bags to be sure that the Seal Time is set
properly. The Seal Time may need to be increased (+) or decreased (-) to
optimally seal a bag. We recommend 3 seconds for our 3 mil bags.
1. Ensure that the unit is plugged in & turned on.
2. Select a bag that is at least 2" (5 cm) longer than the item you are sealing.
Or prepare a bag from a roll using the "PREPARING VAC BAGS FROM A
ROLL" section.
3. Place open end of bag you desire to seal over Sealing Bar and in the
center of the Vacuum Chamber (in center of the oval of the Lower Oval Vacuum
Chamber Seal).
4.
Ensure that the bag is not covering the vacuum port.
5. Close the Lid while holding the bag in place.
6. Press the Manual Seal button. You will need to apply pressure to the handle
at the beginning of the countdown process to create a proper seal. Vacuum pump
will engage briefly to help create a proper seal.
7. After the Seal Monitor counts down to zero (0) the unit will automatically
release the vacuum and enable the Lid to open.
8. Remove the bag and inspect the seal. The seal should appear smooth and
consistent all the way across the bag. The seal SHOULD NOT melt through the
bag at any point. Be sure there are no creases or wrinkles that may allow air to
leak into the bag. A properly sealed bag will not pull apart.
9. Do not form side seals on the bags, the sides are already sealed.
10. If the seal is good, proceed with vacuum packaging. Otherwise:
. If the seal is melted through the bag trim off the bad seal with scissors and adjust the
Seal Time Down (-) in one second increments and try the test process again.
. If the seal has not fully welded the bag closed, trim off the bad seal with scissors and
adjust the Seal Time Up (+) in one second increments and try the test process again.

Do not attempt to pull the lid open before the vacuum has been released. Always wait at
least 30 seconds before sealing another bag to avoid overheating. Leave lid open to allow
10
seal bar to cool more quickly.
