DESCRIPTION
WARNINGS
If used in accordance with the intended use, machines bearing the CE brand
comply with the requirements of the machinery directive CE 2006/42/EC.
To ensure the protection of people and prevent material damage, it
is compulsory to comply with the instructions stated in this manual
and in any other piece of documentation attached to this equipment.
To ease any possible order of spare parts or inform you about the
automatic vacuum unit, we advise you to write down all the
information included in the rating plate, on this page, right after
receiving the equipment.
USAGE
!
HANDLING AND STORAGE
Make sure that the forklift has enough lifting power! centrals are quite heavy
(>400 kg).
If there is a long period of time (1 year) between delivery and commissioning,
store it under favorable conditions (in dry rooms, protected from dust and
shocks). Follow the instructions in the manual of commissioning, operation
and maintenance of the vacuum pump.
Fix the tank to the floor using the holes in the feet. The load bearing
capacity of the floor on which the machinery is installed must be
sufficient to bear its weight.

RATING PLATE
Unit type: VACUUM CENTRAL........................................
Serial N°. ........................................................................
USAGE
Usage in accordance with the intended use: the automatic vacuum central
is a system that allows the recovery of vehicle motor oil by means of a
vacuum pump.
Suction of any other fluid can lead to serious body injury or death, as
well as material damage. For more information, please contact us.
LOCATION AND TEMPERATURE
Your automatic vacuum central should operate in a properly ventilated,
dust-free and frost-free location so that the lubricating oil in the pump does
not solidify.
The maximum ambient temperature must not exceed 40 ° C and, if possible,
it should be between +10 ° C and +30 ° C.

WORKING PRINCIPLE AND OPERATION MODE
Daily programing
If the «AUTO/MANU» button is in position “AUTO”, the
power plant operates according to a daily schedule from
Monday to Friday from 7:00 am till 7:00 pm. Schedules
are modifiable. Consult us.
In position “Manu”, the power plant operates
continuously 24h / 24h and 7j / 7j.
The working principle is identical to the standard version. The opening and closing of the isolation valves B of the tank 1 and 2 are associated as well as
the drainage valves D. Activation of the detectors of the tanks 1 or 2 starts the emptying of the 2 tanks.
CIRCUIT DIAGRAM. DOUBLE CENTRAL 393104.
WORKING PRINCIPLE
1. Vacuum pump running
The vacuum pump switches on automatically when the Time Prog = ON, on
lack of vacuum (if sensor option) and during emptying phases.
The vacuum pump can be stopped by the «OFF/ON» button.
A message appears on the screen.
In case of disjunction, an alarm is triggered by displaying “*ALARM*”
flashing on the main page, then you must go to the alarms page.
Option: If the pump is equipped with an oil level sensor and it is activated,
it will only be taken into account after 60 seconds and will block the
operation of the pump. An oil fault alarm will appear.
NOTE: In the case of 2 vacuum pumps, both pumps operate at the same time.
2. Liquid pumping
Valves status:
A(pneumatic valve for isolating pump): open.
B(pneumatic valve for isolating network): open.
C(pneumatic valve for air inlet): closed,
D(pneumatic valve for drain): closed.
3. Draining
The pump is switched off during this phase.
The emptying can be triggered by 4 events:
• at each power-up and from Monday to Friday at 7H00,
• 5 hours after switching on,
• press the drain push button,
• triggered by the level sensor.
A message on the PLC indicates which of the events has activated the draining.
4. Pumping operation to draining operation
Valves A and B are closed to isolate the network and pump.
Valve C opens: the pressure in the receiver increases. It is limited by a
regulator set at 0.4 bar.
If the pressure in the receiver doesn’t reach +400 mbar after “Pressure
flushing” – 10 seconds (120s - 10s = 110s), the “P.FLUSHING” alarm is
triggered. Emptying and suction are stopped.
Valve D only opens after 60 seconds (vacuum breaker time - parameter can
be changed). The liquid is drained from the receiver and the emptying lasts
5 minutes (parameter can be modified).

TOWARDS
THE PUMP
ACCIDENTAL
LIQUID INLET
INSTALATION
NETWORK CONNECTION
In order to transport the liquid correctly and avoid the losses in the lines, we
recommend 2’’piping. It must not exceed a maximum height of 3 meters from
the ground. Plan a slight slope towards the tank to avoid a low point at the end
of the line.
VACCUM CHANNEL
Connect the tank drainage to allow automatic drainage.
With respect to the ground, piping should not exceed two meters.
PNEUMATIC SUPPLY
Supply compressed air to the decompressor with a maximum pressure of 6
bars, with clean air without moist. The pressure after the regulator valve is
set at 0.4 bars and the safety valve at 0.5 bars.
The regulator and discharge valve are adjusted and preset from factory.
Incorrect setting of these items can cause high pressure in the tanks
which are not intended for operation in such conditions.
!
ELECTRICAL SUPPLY
All operations on the machine must be carried out without electrical power.
The connection must be made by a qualified electrician.
All operations on the machine must be carried out without electrical power.
The connection must be made by a qualified electrician.
Check in the motor plate or in post plate that voltage corresponds to that of
the electrical grid.
Feed the workstation with an electric cable whose section corresponds to the
max power.
All motors are protected with a magnetothermic switch.
1.1 kW for 393103 and 393104, 2.2 kW for 393105 ie 1.5 mm²
Power supply L1 - L2 - L3 - Neutral + earth (400V).
The protections to be installed would be 4A for 393103 and 393104 and
10A for 393105.
Refer to the electrical diagram.
!
COMMISSIONING
Check the oil level of the vacuum pump.
Before starting up, read the set up and maintenance manual of the
vacuum pump.
Set the main switch (IG) to I (run) position and press immediately the red
“STOP” button to stop the pump.
Press the green button “RUN” to make the pump rotate and check
immediately the direction of rotation. An arrow indicates the direction of
rotation in the motor. If the direction is not correct, stop the pump
immediately with its M / A button. Reset the correct direction of rotation
swapping the two phases.
Allow the system to increase the vacuum and then proceed to the suction
operations.
Vaccuum can be activated:
• With each connection to the electrical power supply.
• 5 hours after the electrical power connection.
• With the activation button of the box.
• By detecting the level with the level sensor.
WORKING PRINCIPLE AND OPERATION MODE
WORKING PRINCIPLE
5. Draining operation to pumping operation
Valve C is closed: the pressure in the receiver drops. After 30 seconds (flush
time), valves A and B are open and valve D is closed.
6. Liquid trap to protect the vacuum pump:
The liquid trap is a safety device. If, accidentally, the maximum level of the
receiver is reached, the liquid can migrate towards the pump. It will be
trapped before the pump by the liquid trap.
If the quantity of liquid is very important, the level of the liquid trap increases
and, at its maximum level, an obturator cuts the vacuum.
The liquid trap must be emptied:
• Switch off the vacuum pump.
• Open valve so that the liquid fills glass jar.
• When the glass jar is full, close the valve.
Unscrew the glass jar and empty its contents into a
suitable recipient for subsequent recycling according to
environmental protection legislation.
Screw the glass jar back on and repeat until the jar is empty. It is possible
that the mechanical obturator will remain in the up position once the
emptying is complete. Just open the valve and close it again.
