Canister Guidelines (Continued)
• Powdered or granulated foods should be covered with a paper towel before vacuuming
to prevent food from traveling into the vacuum mechanism.
• Vacuum packaging is not a substitute for canning. Perishable foods still need to be
refrigerated or frozen.
• Hot foods should be cooled before vacuuming; the vacuum eect will be inuenced
if not cooled.
• Because of the dierent air pressure, the canister lid should be removed when putting
the canister in the microwave.
• Foods in canister should be thawed or at room temperature before heating in the
microwave.

Pro90 Trouble Shooting
Under the proper circumstances, the Pro90 will give you top-notch vacuum performance.
In some instances, problems may arise. Please consult the trouble shooting menu before
calling customer support.
Note: To protect the machine, a 4 second delay has been programmed in between each
time the seal wire heats. For every 10 times of continuous heating, there must be a total
of 135 seconds non-working time. Otherwise, the machine will go into a protective mode,
the indicated light will illuminate and the machine cannot be used. After resting at least 2
minutes, the indicated light will return to normal, and the machine can begin use again.
Pro90 won’t turn on
• Ensure that the machine is properly plugged into a grounded outlet.
• Check power cord for tears and frays. Do not use if power cord is damaged.
Pro90 doesn’t pull a complete vacuum with bag
• To vacuum and seal properly, the edge of the bag must be within the sealing strip.
Make sure the bag is inside the chamber ring and there are no wrinkles in the bag
along the seal bar.
• If packaging from a roll bag, make sure rst seal is complete and there are no gaps in
either seal.
• Pro90 and vacuum bag need to be clean, dry and free of debris for the vacuum process
to be successful. Wipe surface of seal bar and inside of bag and try again.
Vacuum bag loses vacuum after being sealed
• Sharp items can puncture small holes in bags. To prevent this, cover sharp edges with
paper towel and vacuum in a new bag.
• Some fruits and vegetables can release gases (out-gassing) if not properly blanched or
frozen before packaging. Open bag. If you think food spoilage has begun, discard food.
If food spoilage has not yet begun, consume immediately. If in doubt, discard food.
