Manual N° 514774 version 8 05/2013 Page 3/12
SECTION 2. DESCRIPTION
A LABOVAC vacuum unit can consist of:
one liquid-ring vacuum pump and one attached receiver :...........LABOVAC 1,
two liquid-ring vacuum pumps and one attached receiver :.........LABOVAC 2.
2.1. Liquid-ring vacuum pumps
LABOVAC vacuum units are mounted with ANTIGUA liquid-ring vacuum pumps.
2.2. Receivers
The receivers are made especially for vacuum and designed according to the current code.
The so-called "secondary" receiver will be installed as a "cul de sac" on the main pipework. It will enable the plant
to be correctly controlled. This secondary receiver can be fitted close to or a long way from the main receiver
without any problem.
2.3. Filtration and exhaust pot
A antibacterial filtration unit traps bacteria before they reach the receivers and the vacuum pumps.
The unit is equipped with a single antibacterial filtration with BY-PASS consisting of a main filter: When replacing
the cartridge of the filter in by-pass mode, the air is not filtered and the pump(s) may temporarily become polluted.
Our main bacteria filter is a pot/opaque filter containing a special bacteria cartridge fitted with a deflector.
This filter is opaque to prevent bacteria from proliferating in the filter element. The cartridge is made of
microfibres bound with borosilicate, and its filtration fineness is approximately 1/100th of a micron. This
cartridge passes the so-called sodium flame test. Penetration of bacteria and living micro-organisms is well
below 0.05%, a value generally demanded by standards in various countries.
A sterilisable transparent pyrex bottle is screwed to the base of the filter units.
An exhaust pot is placed on the exhaust circuit, located at the lowest point. Its purpose is to separate air
from water.
2.4. Electrical box
One electric control panel combines the motor control and protection systems.
For LABOVAC 1: 1 x LG7 with mechanical pressure switch for regulation.
For LABOVAC 2: 1 CYCLIC 2020 electronic system with analogue sensor for regulation or 1 MILLENIUM control
device.
SECTION 3. OPERATION
The air conveyed by the vacuum network passes through the main bacteria filter, enters the main receiver and is
then sucked by the vacuum pump(s) of the vacuum unit/plant.
The exhaust system consists of an exhaust hose fitted with a AIR/WATER separator collecting pot on a by-pass at
the lowest point of the network.
SECTION 4. CHOICE OF ROOM
The unit must be installed in clean, properly ventilated room with a temperature between +5°C and +38°C.
Low-level ventilation (cool air) and high-level ventilation (hot air outlet) are required. A heat extractor fitted with a
silencer and automatic shutters is available on option. It is controlled by a thermostat.
For information purposes, the table below gives the amounts of heat that must be extracted, according to the
installed capacity in kW.

SECTION 5. REGULATION BY SENSOR OR VACUUM PRESSURE SWITCH
LABOVAC 2 fitted with the CYCLIC 2020 are regulated by a 4/20mA analogue sensor which measures pressures
in ABSOLUTE terms and can transmit the values to the monitors selected by the user, in either RELATIVE or
ABSOLUTE mode. This measurement principle means that plants can be installed at any altitude without the need
to make corrections.
LABOVAC 2 fitted with the MILLENIUM control device are regulated by a 0–10V analogue sensor which
measures pressures in RELATIVE terms.
LABOVAC 1 equipped with the LG7 electrical box, are regulated by a mechanical vacuum switch. These
instruments measure pressures in RELATIVE terms and must be set according to where they are installed, using
the values in the table below.
N.B.: for the CYCLIC 2020 or MILLENIUM, the analogue sensor is backed up by mechanical vacuum switch fitted
as a safety measure, which must be set according to the altitude at which they are used.

turning in the wrong direction, immediately stop pump A using the On/Off switch and inverse the power supply
wires.
Once this check has been carried out, stop pump A by positioning the On/Off switch for the pump to O (Off).
Repeat these steps for vacuum pumps B (Only LABOVAC 2).
Close the main receiver bleed valve and open the network outlet valve.
Position all the pumps’ switches to On (I) and all the pumps will start up resulting in a steady increase of the
depression within the network.
Check all connections for leaks.
To check that the chosen set up is operating correctly:
isolate the system from the network by closing the outlet valve,
induce a controlled leak by partially opening the bleed valve of the main receiver.
once this check has been carried out, make sure the bleed valve is properly closed and open the network
outlet valve.

Note: If a secondary filter is fitted to the station: this filter is not designed to work continuously but only during
cartridge changeover interventions on the main filter which must be undertaken as swiftly as possible.
If the secondary filter becomes clogged, then the main filter will also be clogged and loss of vacuum may result.
12.2. Liquid-ring vacuum pump
IMPORTANT:
For this operation, use all necessary protective clothing (gloves, mask, chemical protective
suit, etc.) to avoid infection.
12.3. Checking operation of mechanical back-up (only with LABOVAC 2)
Check with relevant authority that this test is suitable for the activity and architecture of the
building in which the network is installed. This action will trigger an alarm.
For CYCLIC 2020 and MILLENIUM:
A mechanical back-up vacuum switch is placed in parallel with the control unit.
- Set the general switch to “O”.
- Remove the power supply to the control unit by removing the protective fuses.
- Turn the general switch back on.
- Reduce the vacuum in the receiver, the pumps should start up at around –450 mbar and stop at
around –700 mbar.
Once the check has been completed, set the general switch to “O”, put the fuses back in place and
then reset the general switch to “I”.
12.4. Validation of sensor measurements – vacuum gauge
For CYCLIC 2020 / MILLENIUM, connect the electronic calibrating vacuum gauge to the bleed valve of the
receiver and check the sensor regulation and the mechanical vacuum gauge.
12.5. Checking operation of the network alarm
Check with relevant authority that this test is suitable for the activity and architecture of the
building in which the network is installed. This action will trigger an alarm.
Each network alarm is fitted with a sliding exhaust valve.
In order to test the alarm, move the sliding part away from the nut. A leak will occur at the sensor and the alarm
will be triggered. Once this test has been completed, set the sliding valve back to its normal position.
