layout:
- V-410 /V-421 /V-426: 15V (20V depending
on the bag type).
- V-641: 15V (short bar), 23V (long bar)
- V-821: 20V (short bar), 30V (long bar)
For the bag cutting operation, it is enough to
programme the suitable sealing time in the
control panel and, once the bag is sealed, it is
separated manually along the line marked by
the cutting thread.
DIRECTIONS FOR USE AND MAINTENANCE
Very important:
-Never pack products if they are still hot,
since the vapour generated by them
damages the vacuum pump.
-Never pack products using gas with an
oxygen content greater than 21% without
previously consulting your supplier or a
SAMMIC-approved TAS.
-It is important to clean the interior and edges
of the chamber, as well as the locking joint,
every day.
-The outside of the machine must not be
washed under a direct water jet; instead you
can use a wet cloth and an ordinary detergent.
Never clean the cover with alcohol, solvent
or glass-cleaners since they can affect the
mechanical properties of the material and
break it. If you appreciate a crack in the cover,
stop the machine and call the authorised
technical service for repairs; there is a risk of
cover breaking.
-In the event the power cable should get
damaged and have to be replaced, the repair
may only be done by a SAMMIC approved
assistance service.
-Before cleaning, repairing or checking the
machine, you must unplug the machine from
the mains.
-The noise level of a machine in operation, as
measured at a height of 1.6m and a distance of
1 metre, is 75 dB(A). Background noise: 32
dB(A).
Oil change
The oil level must be checked weekly. It should
not be below 3/4 of the oil indicator. Complete
the level, if necessary.
Oil must be changed after the first 100 working
hours. Afterwards, change oil every 500
working hours approximately or at least every 6
months, as well as each time oil is found to be
emulsified. The accumulated working hours are
displayed when the machine is switched on. To
change oil, unscrew the draining plug and let
the used oil drain out, then fill the pump with oil
through the inlet, until oil reaches 3/4 of the
indicator. Detergent-free oil must be used:
-SAE10 oil (detergent-free) for pumps with

ENGLISH
outputs up to 20m³/h.
-SAE30 oil (detergent-free) for pumps with
outputs over 20m³/h.
Paraffin oils are recommended.
On pumps with outputs from 40m³/h upwards,
replace the oil filter at the same time. This filter
is of the type used in cars, as per ref: AWS2,
thread 3/4.
The exhaust filtre must be changed every 4 oil
changes or on detecting either oil leaks or oil
mist at the escape.
On turning on the machine when the pump has
been working for a total of 500 hours, the
indicator will display 50 and will be flashing for
10 seconds, indicating that oil must be
changed. During this lapse of time, the machine
will not start, even if the cover is lowered.
Once oil has been changed, reset the pump
working time according to the following
sequence:
-With the cover open, press STOP. The vacuum
pump will start.
-Lower the cover. The machine will start and
perform a normal cycle.
-Once the vacuum process has started, press
the STOP button quickly. At this moment, the
working time has been reset to 0. Allow the
machine to complete the cycle.
-Switch the machine off and on to check that
the working hour display shows 0.
CHANGE OF CONFIGURATION AND TESTING
OF FUNCTIONS
There are three possible configurations of the
electronic board, according to the machine in
which it is fitted.
Configuration "0": Continuous duty, self-
standing machines (V-641 and V-821). The
pump remains on as from the time the main
switch is pressed. This configuration is intended
for machines to be installed in cold rooms and
refrigerating chambers. Because the pump is on
continuously, the machine is kept hot, which
guarantees its proper operation.
Configuration "1": Discontinued duty, self-
standing machines (V-641 and V-821). The
pump is on only during the vacuuming and
sealing stages.
Configuration "2": Discontinued duty, desktop
machines (V-410, V-421 and V-426). The
pump is on only during the vacuuming stage.
In order to change the machine configuration,
follow the procedure described below:
WARNING!
The electronic board is fed at 230V, so care
must be taken thorughout the machine
configuration changing and testing process.
1- Take off the control panel by removing its 6
front fixing screws and then remove the
cover protecting the electronic circuit.
2- Press the general switch.
3- Locate two lugs near the word "TEST" on the
electronic board and short-circuit them with
a screwdriver or similar object. At this
moment, the test process starts: the
electronic board activates each output
(Motor, Vacuum solenoid valve, Sealing
solenoid valve, etc.) for one (1) second and
its associated LED on the board should then
turn on. Next to each LED, there is a text
identifying the component being tested.
4- On completion of the test sequence, display
1 indicates the machine configuration while
display 2 shows the pump working time. If
you press STOP at this stage, the pump
working time counter will be zero-reset.
5- In order to change
configuration, press the Prog key: its built-in
LED will turn on. Press the Incrementer or
Decrementer key until
configuration value is shown in display 1.
6- Press Prog in order to save the new
configuration. Its LED turns off.
7- To exit the test mode, switch the machine
off. If you lower the cover before exiting the
test mode, the machine will not start. After
having changed the configuration
resetting the working time counter, you can
read the new value on the corresponding
display when the machine is switched on
again.
The electronic board has a function testing
feature as an aid to troubleshooting in the event
of a machine failure.
Execute steps 1 and 2 described in the previous
section. If any component fails to work during
the test, proceed as follows:
-Verify that the component is connected
correctly and is energised. If this is OK and the
component still fails, replace it by a new one.
-If the component is not energised, check the
voltage at the output of the electronic board
when the associated LED is on. If there is no
voltage, change the electronic board.
