5. FAQ – ADDITIONAL INFORMATION
Question: How much longer will my products last?
Answer: Typically shelf life of vacuum packed prod-
ucts may be extended three to fi ve times. It depends,
however, on the type of product, earlier handling,
storage temperature, conditions before and after
packing etc.
Question: What are the advantages of vacuum
packaging my products?
Answer: There are many advantages of vacuum
packing, e.g. longer shelf life, no changes to the
product, no weight loss resulting from evaporation,
easy labelling (date, weight, best before date, pur-
pose), considerable reduction of aerobic bacteria,
easier storage and control of products, reduced
costs thanks to longer storage, possibility of stor-
ing large quantities, excellent appearance of the
vacuum packed product, better protection against
contamination, easier transport of the product,
better appreciation of product quality by customers
and consumers.
Question: How does sealing temperature affect
the sealing of bag?
Answer: Setting sealing temperature (HIGH, MID-
DLE, LOW) is related to the sealing function, there-
fore if the sealing level is low (1-2 seconds), then
temperature should be set at middle/high level
and if the sealing parameter is high (more than 3-4
seconds), then the temperature setting should be
middle/low. In each case please test the setting on
a bag.
Question: How to select proper vacuum time for
a specific bag and product size?
Answer: The smaller the product is, the longer vacu-
um generation time should be set.
Usually 30 seconds is enough to properly pack a 300
g product in a small bag (16/23 cm). Moreover, it
is not always necessary to generate high vacuum,
if you want to pack a product without generating
high vacuum, a dozen or so or even a few seconds
of vacuum time will suffi ce. You should always test
your settings and repack the product if necessary.
Question: Can I vacuum–pack liquids/sauces?
Answer: Yes, you can vacuum-pack liquids and sauces.
Question: Can I crop the bag to adjust it to a small
product?
Answer: Yes, you can cut off the open edge of the
bag with scissors or a knife.
Question: If I vacuum package my food products,
will I still need to refrigerate them?
Answer: Yes, vacuum packaging is not a substitute
to refrigeration.
Question: Do I need to heat the machine up before
turning it on?
Answer: In temperature of 18-24°C,
the machine needs max. 3 min after switching on
to be ready for work. If the ambient temperature is
below 18°C, we recommend starting the machine
up 7 minutes after it has been turned on and set-
ting the sealing time at 0 seconds to properly dis-
tribute oil.
Question: What products can be vacuum-packed?
Answer: You can vacuum pack products that are
resistant to vacuum, i.e. any food products, metal
elements, clothing, money etc.
Question: What type of bags should I use for vac-
uum-packing?
Answer: We recommend Victor Vacuum Bags
which are dedicated for our machines. Please con-
tact your distributor or our company.
Question: How often should I replace or replenish
oil?
Answer: Oil should be replaced, i.e. drained after
it turns dark brown (dirty) colour or at least once
every 6 months. Before starting the machine, it is
necessary to fi ll half of container with oil and then
keep this level by replenishing oil (please check oil
level every month). Oil is delivered with the ma-
chine. We recommend Victor Vacuum Oil.
