Dear customer,
Your VACUUBRAND controllers are designed to provide you with many
years of trouble-free service with optimal performance. Our many years
of practical experience allow us to provide a wealth of application and
safety information. Please read these instructions for use before the ini-
tial operation of your controller.
VACUUBRAND controllers combine our many years of experience in de-
sign, construction and practical operation, with the latest developments
in material and manufacturing technology.
Our quality maxim is the ”zero defect” principle:
Every controller, before leaving our factory, is tested intensively, including
an endurance run. Any faults, even those which occur rarely, are identi-
ed and can be eliminated immediately.
After completion of the endurance run, every controller is tested, and
must achieve specications before shipment.
We are committed to providing our customers only controllers that meet
this high quality standard.
While our controllers cannot eliminate all of your work, we design, manu-
facture and test them to ensure that they will be an effective and trouble-
free tool to assist you in that work.
Yours,
VACUUBRAND GMBH + CO KG

move the product from its packing-box and retain all pack-
aging until the equipment is inspected and tested. Inspect
the equipment promptly and carefully.
If the equipment is damaged, notify the supplier and the
carrier in writing within three days. Retain all packing ma-
terial for inspection. State the item number of the product
together with the order number and the supplier’s invoice
number. Failure to check and give notice of damage will
void any and all warranty claims for those deciencies.
Store the equipment in dry and non-corrosive conditions
(see also “Technical data”, pg. 21) if the equipment is
not used immediately.
Valves and/or vacuum pumps are necessary to operate
the vacuum controller. Otherwise the controller will oper-
ate as measuring device.
+Do not use any damaged equipment.
Intended use
+Ensure that the individual components are only con-
nected, combined and operated according to their de-
sign and as indicated in the instructions for use.
Use only original manufacturer’s spare parts and
accessories. Otherwise the safety and performance
of the equipment, as well as the electromagnetic com-
patibility of the equipment might be reduced.
The CE mark or the cTÜVus mark may be voided if not
using original manufacturer’s spare parts.
+Comply with all notes on correct vacuum and electri-
cal connections; see section “Use and operation”, pg.

+40°C), or for short periods up to +176°F (+80°C) at
the pressure transducer (gas temperature). Periodical-
ly check maximum temperatures if installing the con-
troller in a cabinet or a housing. Make sure ventilation
is adequate to maintain recommended operating tem-
perature. Install an external automatic ventilation sys-
tem if necessary. If processing hot gases, make sure
that the maximum permitted gas temperature at the
pressure transducer is not exceeded (see “Technical
data”, pg. 21).
• Ensure that the wetted parts are chemically resistant
to the processed substances prior to operation.
Use the equipment only as intended, that is, for mea-
surement and control of vacuum in vessels designed for
that purpose. Any other use will automatically invalidate
all warranty and liability claims.
Remain aware of safety and risks.
Setting up and installing the equipment
+Do not permit any uncontrolled pressurizing (e.g.,
make sure that pipelines cannot become blocked) to
avoid a risk of bursting!
+ Keep the VACUU•BUS cables away from heated sur-
faces.
• Comply with maximum permissible pressures at the
pressure transducer. See section “Technical data”, pg.
21.
• Connect hoses gas tight at the measurement connec-
tion.
• Secure hoses at hose nozzles (e.g., with hose clamp)
to prevent their accidental slipping.
• Check the power source and the equipment’s rating plate
to be sure that the power source and the equipment
NOTICE

page 15 of 80
match in voltage, phase, and frequency.
• When working with residues, aggressive or condens-
able media, install a gas washing bottle if necessary.
Using a wall power supply, assemble and lock the suit-
able power plug (included in shipment) to the power sup-
ply prior to use.
The controller is equipped with a short-circuit-proof, wide-
range power supply with an integrated overload protec-
tion.
Avoid high heat supply (e.g., due to hot process gases).
Position the controller CVC 3000 and its vacuum line in
such a way that condensate cannot ow towards the pres-
sure transducer.
In case connect inert gas at the venting connection.
Allow the equipment to equilibrate to ambient temperature
if you bring it from cold environment into a room prior to
operation. Notice if there is water condensation on cold
surfaces.
Comply with all applicable and relevant safety require-
ments (regulations and guidelines). Implement the re-
quired actions and adopt suitable safety measures.
Ambient conditions
➨Do not reach for this product if it has fallen into liquid.
There is a risk of deadly electrical shock. Unplug the
system immediately.
+Do not use this product in an area where it can fall or
be pulled into water or other liquids.
• Adopt suitable measures in case of differences from
recommended conditions, e.g., using the equipment
outdoors, conductive pollution or external condensa-
tion.
NOTICE

page 16 of 80
• Do not operate this product near ames.
To the best of our knowledge the equipment is in com-
pliance with the requirements of the applicable EC-direc-
tives and harmonized standards (see ”Declaration of Con-
formity”) with regard to design, type and model. Directive
EN 61010-1 gives in detail the conditions under which the
equipment can be operated safely (see also IP degree of
protection, “Technical data”, pg. 21).
Operating conditions
➨This device is not approved for operation in potentially
explosive atmospheres. Do not operate the device in
potentially explosive atmospheres.
➨Controllers without the ”`” mark on the rating plate
are not approved for operation with dangerous or
explosive gases or with potentially explosive or
inammable substances. Do not operate the con-
troller with dangerous or explosive gases or with
potentially explosive or inammable substances.
➨Controllers bearing the ”`” mark on their rating
plates are approved for operation with potentially
explosive atmospheres according to their classica-
tion II 3G IIC T3 X according to ATEX, but they are
not approved for operation in potentially explosive
atmospheres (see section “`Important information:
Equipment marking (ATEX)”, pg. 19).
• Ensure that the materials of the controller’s wetted
parts are compatible with the substances in the vacu-
um system, see section “Technical data”, pg. 21.
NOTICE

page 17 of 80
Safety during operation
➨Adopt suitable measures to prevent the release of
dangerous, toxic, explosive, corrosive, noxious or pol-
luting uids, vapors and gases.
+Never operate this controller if it has a damaged cord
or plug. If the controller is not working properly, has
been dropped or has fallen into water, contact your
service provider.
+Prevent any part of the human body from coming into
contact with vacuum.
+ Attention: At pressures above approximately 795 Torr
(1060 mbar) the pressure reading becomes incorrect
due to saturation of the pressure transducer. The dis-
play ashes. Release pressure immediately! Risk of
bursting!
• You must take suitable precautions to prevent any
dangerous situation from arising if the controller starts
a NT VARIO or VARIO-B pump, switches an in-line
valve or a coolant valve, switches a vacuum pump (in
combination with a VMS module), or opens a venting
valve.
• Attention: If the controller is set to Autostart, the pro-
cess will start immediately after a power failure with-
out pressing any further key. It is your responsibility to
ensure that automatic start-up of the system will not
lead to any dangerous condition. Provide appropriate
safety measures. Check prior to starting the process
whether the option ”Autostart” (menu: conguration) is
enabled.
Electronic equipment is never 100% fail-safe. This may
lead to an ill-dened status of the equipment or of other
connected devices. Provide appropriate protective mea-
sures to allow for the possibility of failure and malfunction.
The protective measures must also allow for the require-
ments of the respective application.
NOTICE

Important information: Equipment marking (ATEX)
VACUUBRAND equipment bearing mark (see rating plate)
`II 3G IIC T3 X
Internal Atm. only
Tech. File Ref.: VAC-EX01
The classication II 3G IIC T3 X according to ATEX is only valid for the in-
ner part (wetted part, pumped gas or vapor) of the equipment. The equip-
ment is not suitable for use in external, potentially explosive atmospheres
(environment).
The overall category of the equipment depends on the connected com-
ponents. If the connected components do not comply with the classi-
cation of the VACUUBRAND equipment, the specied category of the
VACUUBRAND equipment is no longer valid.
Vacuum pumps and vacuum gauges in category 3 are intended for con-
nection to equipment in which during normal operation explosive atmo-
spheres caused by gases, vapors or mists normally don’t occur; or, if they
do occur, are likely to do so only infrequently and for a short period only.
Equipment in this category ensures the requisite level of protection dur-
ing normal operation.
The use of gas ballast or the operation of venting valves is only permit-
ted if thereby explosive atmospheres normally don’t occur in the interior
of the equipment or, if they do occur, are likely to do so only infrequently
and for a short period.
The pumps are marked with ”X” (according to EN 13463-1), i.e., restric-
tions of the operation conditions:
• The equipment is designated for a low degree of mechanical stress
and has to be installed in a way so that it cannot be damaged from
outside.
Pumping units have to be installed so that they are protected against
shocks from the outside and against glass splinters in the event of
breakage (implosion).

page 20 of 80
• The equipment is designated for an ambient and gas inlet temperature
during operation of +10 to +40°C. Never exceed these ambient and
gas inlet temperatures. If pumping / measuring gases which are not
potentially explosive, extended gas inlet temperatures are permissible.
See instructions for use, section “Gas inlet temperatures” or “Techni-
cal data”.
After any intervention at the equipment (e.g., repair / maintenance) the ul-
timate vacuum of the pump has to be checked. Only if the pump achieves
its specied ultimate vacuum is the pump’s leak rate low enough to en-
sure that no explosive atmospheres will occur in the interior of the equip-
ment.
After any intervention at the vacuum sensor, the leak rate of the equip-
ment has to be checked.
