FILLING THE
POUCH
The item should be placed and/or turned so that a minimum of empty space
remains. In some cases for non-rectangular or odd sized products, it may be best to
“wedge” two or more sections together so that they more closely conform to the
rectangular shape of the pouch.
Make it a habit to load the pouch carefully keeping the sealing as clean and dry as
possible. Although the VACMASTER can generally seal through liquids, a clean
dry sealing surface will always result in a seal with the best integrity and
appearance.
PLACE BAG IN
THE
CONTAINER
Remove or replace filler plates as required to accommodate the package thickness.
Filler plates serve two purposes. 1). They function as a platform so that thinner
items can rest flat at about the same height as the sealing bar. 2). They occupy
unneeded volume. This will allow you to set the pump timer to a lower setting
without compromising the ultimate vacuum level. In other words, filling excess
areas in the chamber with plates displaces air and allows the pump to reach its
ultimate vacuum level on a faster, more efficient cycle.

Lay the bag in the chamber so that ½ ” to ¾ ” of the open end of the bag is resting
evenly across the seal bar. Check the bag to make sure that the sealing surfaces is
as free of wrinkles as possible.
When packaging multiple pouches in the same cycle, align side by side, but do not
overlap, the seal area.
CHECK
CONTROLS Vacuum Timer (left control knob
). The vacuum pump timer can be set so that the
unit runs from 5 to 60 seconds. The more that you turn the knob to the right
(clockwise) the longer the pump will run.
In most cases, the objective is to select the minimum time setting which will allow a
full vacuum to develop (the gauge steadies at 28-30
” Hg). This is influenced by
several factors including the two following:
1).
Amount of empty space remaining in the chamber.
The more space left
unfilled either by product in bags or filler plates, the more air which must be
evacuated and the longer it will take to reach full vacuum.
2).
Moisture content of the product
. As a general rule, the higher the percentage
of moisture in the product, the higher the setting may need to be adjusted.
NOTE:
The gauges on the VACMASTER are built and designed with a ±2%
accuracy and they are calibrated for sea level conditions. Your actual gauge reading
may vary depending on altitude above sea level, as well as the variance from
nominal of your particular gauge. Learn to use the gauge as a
relative
indicator of
vacuum level only.
Seal Bar Timer (right control knob).
The seal bar timer is a 0-3 second timer.
The more the knob is turned to the right, the longer the power (heat) will be put to
the seal bar and the thicker the pouch material that can be sealed.
A timer setting that is too short will result in an insufficient seal and the bag will
leak within a short period of time. A timer setting which is too long will result in a
burn through the bag in the area of the seal.
CLOSE THE LID
Hold the lid down firmly for 2 or 3 seconds. You will hear the vacuum pump start,
the pump timer red indicator will light, and the cycle will begin. As vacuum builds
in the chamber, the lid will stay closed on its own.
At this point, the automatic cycle begins. As you watch the gauge, you will see the
needle move up from 0 toward the 28-30
” mark. If you look at the pouch in the
chamber, you may notice that the bag actually appears to “puff up” at first. This is
normal and in fact, indicates that the pump is working efficiently.
