Dear customer,

Your VACUUBRAND diaphragm pump shall support you at your work for a long time without any trouble and with full load output. Thanks to our large practical experience we attained much information how you could add to an efficient application and to personal safety. Please read these instructions for use prior to the initial start-up of your pump. VACUUBRAND diaphragm pumps are the result of many years of experience in construction and practical operation of these pumps combined with the latest results in material and manufacturing technology.

Our quality maxim is the ”zero fault principle”:

Every delivered diaphragm pump is tested extensively including an endurance run of 18 hours. Due to this endurance run, also faults, which occur rarely, are reported an can be corrected. Every single diaphragm pump is tested on achievement of the specification after the endurance run.

Every VACUUBRAND pump leaving our factory achieves the specification. We feel obliged to this high quality standard.

We are aware that the vacuum pump should not draw a part of the real work and we hope to contribute with our products to an effective and troublefree realisation of your work.

Yours VACUUBRAND GMBH + CO KG

After sales service: Contact your local dealer or call (++49) 9342/808-193.

Remove all packing material, remove the product from its packing-box, remove the protective covers from the inlet and outlet ports and keep, inspect the equipment. If the equipment is damaged, notify the supplier and the carrier in writing within three days; state the item number of the product together with the order number and the supplier’s invoice number. Retain all packing material for inspection.

Do not use the equipment if it is damaged.

If the equipment is not used immediately, replace the protective covers. Store the equipment in suitable conditions.

☞ Read and comply with this manual before installing or operating the equip-

ment.

☞ Transport the pump at the provided handles.

Use the equipment for the intended use only (for generation of vacuum).

☞ Prevent any part of the human body from coming in contact with the vacuum. ☞ Comply with notes on correct vacuum and electrical connections, see section ”Use

and operation”.

☞ Make sure that the individual components are only connected, combined and oper-

ated according to their design and as indicated in the instructions for use.

Comply with national safety regulations and safety requirements concerning the use of vacuum and electrical equipment.

☞ Equipment must be connected only to a suitable fused and protected electrical

supply and a suitable earth point. Failure to connect the motor to ground may result

in deadly electrical shock.

☞ The supply cable may be fitted with a moulded European IEC plug or a plug suitable

for your local electrical supply. If the plug has been removed or has to be removed, the cable will contain wires colour coded as follows: green or green and yellow: earth; blue or white: neutral; brown or black: live.

☞ Check that mains voltage and current conform with the equipment (see rating

plate):

Pumps with dual-voltage motor (100-120 V / 200-230 V; 50/60 Hz): ☞ The equipment must be connected to a suitable fused and protected electrical

supply and a suitable earth point only, provide slow-blow fuse according to voltage

supply (see ”Technical data”).

☞ Check that the voltage changeover switch is positioned correctly.

Attention: If the pump is switched on with the voltage not correctly selected, the motor may be damaged!

☞ If the equipment is brought from cold environment into a room for operation, allow

the equipment to warm up (pay attention to water condensation on cold surfaces).

☞ Make sure ventilation is adequate if pump is installed in a housing or if ambient

temperature is elevated.

Comply with all relevant safety requirements (regulations and guidelines) and adopt suitable safety measures. ☞ Provide a firm level platform for the equipment and check that the system to be

evacuated is mechanically stable and that all fittings are secure. Attention: Flexible elements tend to shrink when evacuated.

Due to the high compression ratio of the pumps, pressure at the outlet port might be generated being higher than the max. permitted pressure compatible with the mechanical stability of the system.

☞ Comply with maximum permitted pressures and pressure differences, see sec-

tion ”Technical data”. Do not operate the pump with overpressure at the inlet.

Do not permit any uncontrolled pressurizing (e. g. make sure that the exhaust pipeline cannot become blocked). If you have an exhaust-isolation valve, make sure that you cannot operate the equipment with the valve closed. Risk of bursting! ☞ Ensure that the system design does not allow the exhaust pipeline to become

blocked.

☞ Avoid overpressure of more than 0.2 bar in case inert gas is connected. ☞ The diameter of the inlet and outlet pipeline should be at the least as large as the

diameter of the pump connection pipelines.

To the best of our knowledge the equipment is in compliance with the requirements of the applicable EC-directives and harmonized standards (see ”Declaration of conformity”) with regard to design, type and model, especially directive IEC 1010. This directive gives in detail conditions, under which the equipment can be operated safely (see also IP degree of protection). ☞ Adopt suitable measures in case of differences, e. g. using the equipment outdoors,

installation in altitudes of more than 1000 m above mean sea level, conductive pollution or dewiness.

Pay attention to symbol ”hot surfaces” on the equipment (according to IEC 1010 recommendation). ☞ Adopt suitable measures to prevent any danger arising from the formation of hot

surfaces or electric sparks.

The pumps have no approval for operation in or for pumping of potentially explosive atmospheres.

If pumping different substances, purge the pump with inert gas prior to changing the pumped media in order to pump out residues and to avoid reactions of the pumped substances with each other with and the pump material. Ensure that the materials of the wetted parts are compatible with the pumped substances, see section ”Technical data”.

Take into consideration interactions and chemical reactions of the pumped media.

The pumps are not suitable for pumping substances which may form deposits inside the pump. ☞ If there is a danger of the formation of deposits in the pump chamber (check inlet

and outlet of the pump) inspect the pump chamber regularly and clean if necessary. The pumps are not suitable to pump unstable substances and substances which react explosively under impact (mechanical stress) and/or when being exposed to elevated temperatures without air. The pumps are not suitable to pump self inflammable substances, substances which are inflammable without air and explosive substances. The pumps are not suitable for pumping dust and have no approval for operation below ground.

Ensure that the materials of the wetted parts are compatible with the pumped substances, see section ”Technical data”. ☞ Adopt suitable measures to prevent the release of dangerous, explosive, corrosive

or polluting fluids.

☞ Use inert gas for gas ballast or venting if necessary. ☞ The user must take suitable precautions to prevent any formation of explosive mixtures

in the expansion chamber or at the outlet. In case of a diaphragm crack, mechanically

generated sparks, hot surfaces or static electricity may ignite these mixtures. ☞ Take adequate precautions to protect people from the effects of dangerous sub-

stances (chemicals, thermal decomposition products of fluoroelastomers), wear

appropriate safety-clothing and safety glasses. ☞ Comply with applicable regulations when disposing of chemicals. Take into consid-

eration that chemicals may be polluted.
