NUMBER OF LABELS: press
or to select the number of labels
printed in each cycle.
• Extra label: When a cycle is finished, press
after opening the lid before 10s without making
another cycle, a new label will be printed.
• Shut down the printer: Press and hold the
"POWER" button until the "ON LINE" indicator
turns red and then turns off.
LABEL PRINTING: VAC-NORM
After having started the vacuum, with the printer
activated, when the setpoint vacuum value has
been reached the pump stops and one label
is printed, indicating the maximum vacuum
reached.
BAG CUTTING
The bars, which include wire for cutting bags,
are supplied as kits.
Install it by changing the sealing bar for the bar
that contains the cutting wire and changing the
connection on one of the cables on the sealing
transformer to the voltage indicated in the wiring
diagram:
To cut the bag, simply set the correct sealing
time on the control board and once sealed drag
the bag manually along the line marked by the
cutting line.

OPERATION AND MAINTENANCE

• Very important: Never pack products if they
are still hot, since the vapour generated by
them damages the vacuum pump.
• NEVER package products using gas with an
oxygen content higher than 20% without first
consulting your supplier or SAMMIC-approved
service. This could cause fatal explosions.
Packaging liquids:
All "SU" models are fitted with a system for
detecting the evaporation of a liquid that is
being packaged. When the liquid evaporates,
the vacuum pressure stops decreasing and if
this happens the electronic control stops the
EN
10
vacuum process and the
up. This is done to help prevent liquid from
contaminating the vacuum chamber and pump
oil.
The symbol remains lit until a new cycle
begins.
Note: Certain mixtures with liquid appearance
but beaten with a mixer contain trapped air in
the mixture. In such situations the detector may
not work optimally, in which case press
the key to PAUSE or
to prevent the liquid from damaging the oil.
To package liquids, use the accessory that keeps
the bag at an angle to avoid spilling the liquid. If
bubbles appear during packaging, the saturation
point has been reached. The saturation point is
similar to the evaporation or boiling point that
occurs at different temperatures depending on
the pressure.
The saturation point is reached sooner the
higher the temperature of the liquid during the
vacuum process. It is recommended to cool the
liquid before packaging to obtain an optimum
vacuum for the product.
The table indicates the saturation point for water
with the relationship between temperature and
pressure. This table approximately outlines the
MAXIMUM VACUUM that can be obtained for
each given product temperature.

Drying the oil:
After working with liquids, it is convenient at
the end of each day to run an oil drying cycle,
which removes moisture contained in the pump
and maintains its ability to make the maximum
vacuum. To do this, select the
program as indicated in the "OPERATION"
section.
Automatic pump shutdown:
In models with continuous pump operation,
if the machine is not used for 10 minutes the
pump stops automatically. This prevents the oil
from overheating, and reduces the amount of oil
deposited in the drainage filters, in addition to
saving energy. When the cover is closed, the
symbol lights pump and the cycle start up simultaneously.
- It is important to clean the inside and edges of
the chamber and gasket seal every day.
- The outside of the machine must NEVER be
cleaned directly with water from a hose. Use
a damp cloth and mild detergent for cleaning.
Never clean the cover with alcohol, solvents
or cleaning products since it can affect the
mechanical properties of the material and cause
it to break. If a crack is observed on the cover,
do not continue working with the machine and
inform the authorised repair service, as there is
a risk of breaking the cover.
- Only a SAMMIC authorised technical service
can replace the power cable if this is damaged.
- Before undertaking any cleaning, inspection or
repair work on the machine, the machine must
be unplugged from the mains.
- Machine noise level, while running, at a height
of 1.6 m and a distance of 1 m, is 75 dB(A).
Background noise: 32 dB (A).
Oil change
The oil level must be checked weekly, which
should cover 3/4 of the spy hole. Fill it if
necessary.
The oil must be changed after the first 100
hours of operation. Then change the oil:
• Desktop models; Model number 2: 150 hours
• Free-standing models; Intermittent pump
operation, Model number 1: 300 hours
• Free-standing
operation, Model number 0: 300 hours
• When the pump has worked the hours

95 96,87 98

indicated, when starting the machine the
viewer will indicate the hours and the
symbol will light up to warn that the oil must be
changed.
• The oil must also be changed if it is observed
that is emulsified. The number of hours
accumulated can be checked when switching
the machine on. To make the change, release
vacuum cover and let the used oil out. For
filling, follow the instructions given in the
corresponding section.
• In pumps 40m³/h and above, the oil filter must
be changed at the same time. This filter is
of the type used in the car according to the
reference: AWS2, thread 3/4.
• The exhaust filter must be replaced every four
oil changes or when oil leaks or oil mist are
