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 30% 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
outputs up to 20m³/h.
-SAE30 oil (detergent-free) for pumps with
outputs over 20m³/h.

ENGLISH
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.
-Lower the cover. The machine will start and
perform a normal cycle.
-During the vacuuming stage, press STOP. 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
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
desktop machines (V-402, V-421 and V-426).
The pump is on only during the vacuuming
stage.
In order to change
configuration, follow the
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
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
configuration, press the Prog key: its built-
in LED will turn on. Press the Incrementer
or Decrementer key until the required
configuration value is shown in display #1.
6- Press Prog in order to save the new
AND 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 or
resetting the working time counter, you
can read
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
duty, 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.
