- 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
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 :
• Tabletop models; Model number 2: 150
hours
• Free- standing models; Intermittent pump
operation, Model number 1: 300hours
• Free- standing models; Continuous pump
operation, Model number o: 300hours
When the pump has been operating during
the hours indicated, when switching on the
machine the display will show "oil" and will
flash for 10 secs to warn that the oil must be
changed.
The oil must be changed as well as each time
it is found to be emulsified. The accumulated
working hours are displayed when the
machine is switched on or by pressing the
"down" key for 3 secs. To change oil,
unscrew the draining plug and let the used
oil drain out. To fill the pump with oil, follow
the instructions given in the relevant section.
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.
RESET PUMP HOURS
Once oil has been changed, reset the pump
working time by observing the following
sequence:
With the lid open and the two central lines on
the display, and pressing the "down" key for
3 secs, the display flashes "oil" and displays
the number of hours of the motor.
Press the "Stop" key for 3 secs and the
number resets to zero.
Wait 10 secs, by pressing "up",
"down", or "Stop" to exit RESET PUMP HOURS.

TESTING OF FUNCTIONS
Configuration of electronic board: model
number
75 dB(A). There are three possible configurations of
the electronic board, according to the
machine in which it is fitted:
Configuration
continuous operation machines. (SV- 604,
SV- 606, SV- 806, and SV- 810). The pump
starts operating from the moment the main
switch is pressed. This configuration is
intended for machines installed in cold
rooms or refrigerating chambers. As the
pump is continuously
machine is kept hot, guaranteeing its proper
operation.
Configuration
intermittent operation machines. (SV- 604,
SV- 606 and SV- 806). The pump is in
operation during the vacuuming and sealing
stage.
Configuration"2": Tabletop and intermittent
operation machines. (SV- 204, V- 306, SV-
310, SV- 410, SV- 420 and SV- 520). The
pump is in operation 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.
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, 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- Once the test sequence is finished, the
configuration of the machine will be
displayed.
5- In order
configuration, press the Incrementer or
Decrementer key until the required
configuration value is shown.
pressing 6- To exit the test mode and save the new
configuration, switch the machine off. If
the lid is closed before exiting the test
mode, the machine will not start. In the
event that the working time counter has
CONFIGURATION AND
"0": Free- standing and
operating, the
"1": Free- standing and
to change the machine
been reset, you can read the new value on
the display when the machine is switched
on again.
Detection of faults
The electronic board has a function testing
feature as an aid to troubleshooting in the
event of a machine failure.
Execute steps 1, 2 and 3 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.
