Basic Safety Instructions
2 Basic Safety Instructions
2.1 General Information
CAUTION !
Warning notices must be observed. Disregarding them may lead to damage to health
and property.
The laboratory vacuum systems must be operated by personnel who can detect impending
dangers and take action to prevent them from materialising.
The user/operator is responsible for correct installation and safe operation.
Prevent condensate collecting in the pump. When pumping vapours which tend to condense,
please ensure that the pump is at operating temperature and that the gas ballast valve is
open when the pump is switched on.
If there is more than one load on one LVS, they must be separated by check valves.
After finishing work with the diaphragm pump, run it for about 10 minutes with an open gas
ballast valve.
The manufacturer or authorized authorised workshops will only service or maintain the labo-
ratory vacuum system if it is accompanied by a fully completed damage report. Precise in-
formation about the contamination (also negative information if necessary) and thorough
cleaning of the laboratory vacuum system are legally binding parts of the contract.
Contaminated laboratory vacuum systems and their individual parts must be disposed of in
accordance with the legal regulations.
The local regulations apply in foreign countries.
2.2 Electricity
The Laboratory Vacuum Systems are supplied for operating mode S1. Please note that the
testing must be repeated in accordance with DIN EN 0105, DIN EN 0702 and BGV A2 in ca-
se of portable devices.
The local regulations apply in foreign countries.
Please note the following when connecting to the electrical power supply system:
• The electrical power supply system must have a protective connector according to DIN
VDE 0100-410 (IEC 60364-4-41).
• The protective connector must not have any breaks.
• The connecting cable must not be damaged.
• All interfaces are under low voltage according to DIN VDE 0100-410.
115022 Ilmvac GmbH 7

Basic Safety Instructions
2.3 Mechanical Systems
Improper use can lead to injuries or material damage. Observe the following instructions:
• Only operate the laboratory vacuum systems with hoses of the specified dimensions.
• The maximum permissible pressure of 1 bar at the suction connection must not be ex-
ceeded.
• Hazardous substances must be separated out as far as this is technically possible before
they reach the pump.
• External mechanical stresses and vibrations must not be transmitted to the pump. Only
use flexible laboratory hoses for connecting laboratory vacuum systems.
• The overpressure generated at the pressure port must not exceed 1 bar.
• The pump must not be used to suck up fluids. Lay the exhaust pipe so that it slopes
downwards, so allowing condensate to flow out of the pump. Collect the condensate and
dispose of it in an environmentally compatible manner.
CAUTION !
Solid particles in the pumping medium impair the pumping action and can lead to
damage. Prevent solid particles penetrating into the pump.
When handling glass vessels, pay attention to:
• Only use glass vessels with a plastic coating for splinter protection.
• Only use vessels which are suitable for use with vacuums (e.g. round-bottomed flasks).
We recommend that only glass components supplied by the manufacturer are used.
Do not use Erlenmeyer flasks.
• Before each evacuation, check glass vessels for damage which might impair their streng-
th, replace them if any such damage is found.
• Do not heat glass vessels on one side only.
• Retardation of the boiling of the gases to be pumped can lead to a sudden pressure in-
crease. Prevent retardation of boiling by means of suitable measures (e.g. turbulent
agitation).
2.4 High Temperatures
The diaphragm pump may heat up as a result of the temperature of the gas being pumped
and through compression heat.
Prevent the following maximum permissible temperatures from being exceeded.
• + 40 °C for the environment, and
• + 60 °C for the gas to be pumped.
The motor for single phase alternating current is protected against overload by an integrated
motor protection switch.

Basic Safety Instructions
2.5 Hazardous Substances
The operating company bears the responsibility for the use of the laboratory vacuum system.
Hazardous and harmful substances must be effectively prevented from escaping.
Ensure that all lines and connections are leak tight.
Handle exhaust gases in accordance with the requirements of the emission protection regu-
lations.
Do not operate the laboratory vacuum system without a separator without a emission con-
denser. The separator can onl y be em ptied after the apparatus has been vented.
Dispose the condensate in an environmentally compatible manner!
The emission condenser has a safety valve. The air evacuation duct with hose must be kept
clear and lead into a suitable air evacuation duct. Throttling the air evacuation duct can da-
mage the valves of the diaphragm pump.
Hazardous substances in the gases to be pumped can cause personal injuries and property
damage. Pay attention to the warning notices for handling hazardous substances.
The local regulations apply in foreign countries.
Combustible Gases
Examine before switching on whether that can form gas combustible gas/air mixtures which
can be promoted! Consider the regulations of the guideline 1999/92/EC.
Explosive gases
The diaphragm pumps is not certified according to ATEX guidelines 94/9/EC.
Aggressive gases
An MPC series diaphragm pump is used for extracting vapours and aggressive gases.
The warranty shall lapse if the LVS is used with diaphragm pumps from other manufacturers.
Especially aggressive gases have to be explicitly checked for material resistance as de-
scribed in chapter 3.1.2 and, if necessary, modified.
Poisonous gases
Use a separator when pumping poisonous or harmful gases. Prevent such substances from
leaking out of the appliance or pump. Treat these substances according to the applicable
environmental protection regulations.
The diaphragm pump, control valves and hose lines can be damaged by poisonous or ag-
gressive gases.
Test the strength and leak-tightness of the connecting lines and the connected apparatus.
Prevent environmental poisons, e.g. mercury, getting into the diaphragm pumps.
Fulfil the requirements, for example:
• German Hazardous Substances Regulation (GefStoffV) of 23. December 2004
• Regulations 2006/121/EC (classification, packaging and identification of hazardous sub-
stances),
• Manufacturer's safety data sheets on hazardous substances.

Description
3 Description
3.1 Design and Function
3.1.1 Laboratory-Vacuum-Systems
The Laboratory Vacuum Systems are supplied as a ready-mounted unit.
The chemical-resistant diaphragm pump (4) is fitted to the base plate of the column (3) and
attached on the suction-side to the separator (7) to protect the pump from foreign matter and
on the pressure-side to the KD 500/5 emission condenser (6) to recover the condensate.
This ensures that hazardous substances are separated out. The safety valve on the emis-
sion condenser protects against an impermissibly high operating pressure on the outgoing
air end.
The complete vacuum controller, with sensor, venting valve and power unit (5), is fitted in the
column (3). (The non-controlled LVS-variant does not have a controller.)
All exposed glass components (6, 7) are coated with transparent plastic as protection a-
gainst bursting. The emission condenser is supplied with insulation.
The power switch (12) and the plug for the power cable (11) as well as the membrane pump
(10), the PC (13) control lead (14) and the water valve (option) (15) are located on the right
of the column.
The LVS types are specially preconfigured according to model.

Description
3.1.2 Diaphragm pump
Design:
The diaphragm pump consists of a pump body and a drive motor.
The pump body consists of a drive shaft and two pump heads. Both pump head contains a
diaphragm and the work valves. The two pump heads are arranged opposite each other. In
the two-stage (Z) diaphragm pump, both pump heads are connected in series.
The pump heads are driven via an eccentric shaft with a connecting rod.
Function:
Motor, eccentric shaft and connecting rod set the diaphragms in stroke movement. This
changes the size of the space between the diaphragms and pump head (pump chamber).
Increasing the size of the pump chamber opens the inlet valve while the outlet valve is clo-
sed (intake process). Decreasing the size of the pump chamber ejects the gas through the
outlet valve.
The valves are actuated by the gas being pumped. A large proportion of fluid in the dia-
phragm pump minimizes the pumping efficiency.
Component Materials
Connection- / pump head PTFE with carbon-fibre reinforcing
Seal EPDM
Screw fitting PVDF / PP
Valves PEEK
Diaphragm fabric reinforced with a PTFE layer
Connecting elements PP
PTFE with carbon-fibre reinforcement, electrically conductive (with manufacturer's certificate
of electrical conductivity).
Material resistance to aggressive media see: “Kunststoff Kautschuk Produkte“, Jahreshand-
buch der Verarbeiter 2000/2001 ("Plastic, Rubber Products“, Annual Handbook of the Proc-
essor 2000/2001), Publisher Hoppenstedt Darmstadt, Vienna, Zurich.
Gas ballast :
Opening the gas ballast valve (17) in the
suction line of the last pump stage allows
air to flow into the pump chamber. This
prevents condensation and flushes the
pump clear.
Operation leads to:
- Increasing the ultimate pressure and
- Increasing the operating temperature.

and the contractually agreed scope of delivery, or if damage is detected.
Please take note of the general terms of business of ILMVAC GmbH.
In case of a claim under warranty, the device must be returned in packaging that is
suitable for protecting it during transport.
5.2 Installation and Connection
• Set the laboratory-vacuum-system on a flat and horizontal surface.
• Remove the protective caps on the connections.
• Connect the suction connector of the LVS to your apparatus with vacuum hose DN8.
• Connect the cooling water tube to the emission condenser.
• The cooling water return flow must be unpressurized.
• Connect the air exhaust to the central air exhaust system.
• Connect the laboratory-vacuum-system to the power supply.
• Check that the connections are properly seated.
5.2.1 General instructions
Observe the basic safety instructions when using the LVS.
The pressure device regulation 97/23/EC must be observed if devices with an overpressure
of 0.5 bar or more are connected.
The pressures at the suction and pressure sides of the diaphragm pump at the time it is
switched on must correspond to the specifications of DIN 28432.
In order to avoid pumping speed losses, all the vacuum connecting hoses used should have
a large nominal diameter and should be laid out so that the lengths are as short as possible.
Avoid rigid connections. They must be assembled carefully in order to achieve a low leak ra-
te.
We recommend fitting non-return valves (order no. 720327) for applications with several
consumers.
The upstream separator on the suction-side serves to protect the diaphragm pump and the
vacuum sensor from condensates and mechanical contamination. It must be used for an ap-
plication. The level in the separator must be monitored and the separator emptied regularly.
The currently valid regulations must be observed when disposing of waste. The separator on
the suction-side can only be removed and emptied after the system has been vented.

Assembly and Installation
The emission condenser enables a 100 per cent recovery of the solvents led through the
vacuum pump. Cooling takes place via the DN 8 hose nipples. Ensure that the outflow is
clear. The safety valve is located at the gas inlet. The rubber valve seal must be checked
for cracks at regular intervals and exchanged when necessary. The exhaust connection must
be unpressurized. The exhaust can be led off through a DN 10 hose into a suitable evacua-
tion duct. There is common solvent reclamation for all the connected systems. Mixing media
must not lead to a hazard for persons, the environment of for the equipment.
Condensable vapours may only be extracted when the pump is at operating temperature.
When doing so, the gas ballast valve should be opened and/or a quantity of air, which is to
be calculated by the user, allowed to enter via the suction port valve. The pressure values
may be increased when doing so. The diaphragm pump's maximum tolerance of water va-
pour pressure can be improved or a cleaning run can be made after finishing work by open-
ing the gas ballast valve (this significantly reduces the pumping speed and ultimate pres-
sure). The vacuum ducts must always be laid sloping downwards so that condensates can
flow into the relevant separators.
In case of soiling by solid matter, the pump heads must be opened and the entire interior
space, including valves and diaphragm, cleaned mechanically (see chapter 7.2.1).
5.3 Storage
The pumps are to be stored in a low-dust, interior room within the temperature range from
+ 5 to + 40 °C and at a relative air humidity < 90%.
Leave the protective elements on the suction and pressure ports. Another equally good pro-
tection may be used.
5.4 Scrap Disposal
CAUTION !
The laboratory-vacuum-systems must be disposed of in accordance with the
2002/96/EC guideline and the specific national regulations.
Contaminated pump systems must be decontaminated according to the laws.
