Dear customer,

Your VACUUBRAND diaphragm pumps 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 initial operation of your pump.

VACUUBRAND diaphragm pumps combine our many years of experience in design, construction and practical operation, with the latest developments in material and manufacturing technology.

Our quality maxim is the ”zero defect” principle:

Every diaphragm pump, before leaving our factory, is tested intensively, including an endurance run of 14 hours. Any faults, even those which occur rarely, are identified and can be eliminated immediately.

After completion of the endurance run, every pump is tested, and must achieve specifications before shipment.

We are committed to providing our customers only pumps that meet this high quality standard.

While our pumps cannot eliminate all of your work, we design, manufacture 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

Intended use

Do not use the pump or any system parts on humans or animals.

Ensure that the individual components are only connected, combined and operated according to their design 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 compatibility of the equipment might be reduced.

page 13 of 76

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 electrical connections; see section “Use and operation”, pg. 36.

+Do not use the pump to generate pressure.

+The pumps are designed for ambient temperatures during operation between +50°F and +104°F (+10°C and +40°C). Periodically check maximum temperatures if installing the pump in a cabinet or a housing.

Make sure ventilation is adequate to maintain recommended operating temperature. Install an external automatic ventilation system if necessary. If pumping hot process gases, make sure that the maximum permitted gas inlet temperature is not exceeded. The maximum permitted gas inlet temperature depends on several parameters like inlet pressure and ambient temperature (see “Technical data”, pg. 24).

+Particles and dust must not enter the pump.

+Do not pump liquids.

•Ensure that the pump is chemically resistant to the pumped substances prior to operation.

	Use the equipment only as intended, that is, for genera-
NOTICE
	tion, measurement, and control of vacuum in vessels de-
	signed 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

Equipment must be connected only to a suitable electrical supply and a suitable ground point. As such, the plug must be plugged into an outlet that is properly grounded. Failure to connect the motor to ground may

page 14 of 76

result in deadly electrical shock.

The supply cable may be fitted with a molded European IEC plug or a plug suitable for your local electrical supply. The cable contains wires color coded as follows: green or green and yellow: ground; blue or white: neutral; brown or black: hot.

Due to the high compression ratio, the pump may generate overpressure at the outlet. Check pressure compatibility with system components (e.g., exhaust pipeline or exhaust valve) at the outlet.

Do not permit any uncontrolled pressurizing. Make sure that the exhaust pipeline cannot become blocked. If there is an exhaust isolation valve, make sure that you cannot operate the equipment with the valve closed to avoid a risk of bursting!

Keep the electrical power cord away from heated surfaces.

•Provide a firm, level platform for the equipment. Check that the system which you are going to evacuate is mechanically stable. Check that all fittings are secure.

Ensure a stable position of the pump without any mechanical contact other than the pump feet.

•Comply with maximum permissible pressures at inlet and outlet and with maximum permissible pressure differences between inlet and outlet. See section “Technical data”, pg. 24. Do not operate the pump with overpressure at the inlet.

•Avoid overpressure of more than 17.5 psi absolute (1.2 bar absolute) in the event that inert gas is connected to the pump, to the gas ballast or to a venting valve.

•Note: Flexible elements will shrink when evacuated.

•Connect hoses gas tight at inlet and outlet of the pump.

•Ensure that no foreign objects can be drawn into the pump.

page 15 of 76

•Check the power source and the pump’s rating plate to be sure that the power source and the equipment match in voltage, phase, and frequency.

•Ensure that the coolant outlet pipe is always free and that it cannot get blocked. If installing an optional coolant valve, it must always be in the supply line of the exhaust waste vapor condenser.

	Make sure ventilation is adequate to maintain recommend-
NOTICE
	ed operating temperature. Keep a minimum distance of
	2 in (5 cm) between the cooling fan and surrounding items
	(e.g., housing, walls, etc.), or else install an external auto-
	matic ventilation system. Check fan regularly for dust/dirt.
	Clean fan guard grill if necessary to avoid a reduction of
	ventilation.
	Use only hoses at the inlet and outlet of the pump with
	an inner diameter at least as large as the diameter of the
	pump’s tubing (to avoid overpressure at the outlet, and
	reduction of pumping speed at the inlet).
	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.
	Secure coolant hoses at the hose nozzles (e.g., with hose
	clamp) to prevent their accidental slipping.
	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.

page 16 of 76

+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, installation in higher altitudes, conductive pollution or external condensation on the pump.

•Do not operate this product near flames.

	To the best of our knowledge the equipment is in com-
NOTICE
	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. 24).

Operating conditions

These pumps are not approved for operation in potentially explosive atmospheres. Do not operate the pumps in potentially explosive atmospheres.

Pumps without the ”`” mark on the rating plate are not approved for the pumping of potentially explosive atmospheres. Do not pump potentially explosive atmospheres with those pumps.

Pumps bearing the ”`” mark on their rating plates are approved for the pumping of potentially explosive atmospheres according to their classification

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. 22).

The pumps are not suitable to pump any of the substances listed below.

page 17 of 76

Do not pump:

-unstable substances

-substances which react explosively under impact

(mechanical stress) without air

-substances which react explosively when being exposed to elevated temperatures without air,

-substances subject to auto-ignition,

-substances which are inflammable without air

-explosive substances.

The pumps are not approved for operation below ground. Do not operate the pump below ground.

•Do not pump substances which may form deposits inside the pump. The pumps are not suitable for pumping substances which may form deposits inside the pump. Deposits and condensate in the pump may lead to increased temperatures even to the point of exceeding the maximum permitted temperatures.

•Check the inlet and outlet of the pump, if there is a danger of forming deposits inside the pump, e.g., in the pump chambers (the pump chamber is the part between diaphragm and head cover. See section “Replacing diaphragms and valves”, pg. 49). Inspect the pump chambers regularly and clean if necessary.

•Consider interactions and chemical reactions of the pumped media. Ensure that the materials of the pump’s wetted parts are compatible with the pumped substances, see section “Technical data”, pg. 24.

When changing the substances pumped, we recommend purging the pump with air or inert gas prior to changing the pumped media. Purging the pump will pump out residues and it will reduce the possibility of reactions of the pumped substances with each other and with the pump’s materials.

page 18 of 76

Safety during operation

Adopt suitable measures to prevent the release of dangerous, toxic, explosive, corrosive, noxious or polluting fluids, vapors and gases. To prevent any emission of such substances from the pump outlet, install an appropriate collecting and disposal system and take protective action for pump and environment.

You must take suitable precautions to prevent any formation of explosive mixtures in the pump chamber or at the outlet of the pump. In case, e.g., of a diaphragm failure, mechanically generated sparks, hot surfaces or static electricity may ignite these mixtures. Use inert gas for gas ballast or venting, if necessary.

Drain appropriately or otherwise remove any potentially explosive mixtures at the outlet of the pump, or dilute them to non-explosive concentrations.

Never operate this pump if it has a damaged cord or plug.

+If the pump is not working properly, has been dropped or has fallen into water, contact your pump service provider.

+Prevent any part of the human body from coming into contact with vacuum.

+Make sure that the exhaust pipeline cannot become blocked.

Check the overpressure safety relief device at the exhaust waste vapor condenser at appropriate intervals.

+Comply with applicable regulations when disposing of chemicals. Take into consideration that chemicals may be contaminated. Take adequate precautions to protect people from the effects of dangerous substances

(chemicals, thermal decomposition products of fluoroelastomers).

Use appropriate protective clothing and safety goggles.

page 19 of 76

+Interruption of the pump (e.g., due to power failure), failure of connected components or of parts of the supply, or change in parameters must not be allowed to lead to dangerous conditions. In case of a diaphragm failure or in case of a leak in the manifold, pumped substances might be released into the environment or into the pump housing or motor.

Comply with all notes regarding proper use of the pumps, as well as operation and maintenance guidance.

+The residual leak rate of the equipment might render possible an exchange of gas, albeit extremely slight, between the environment and the vacuum system.

Adopt suitable measures to prevent contamination of the pumped substances or the environment.

•Ensure that no parts of your clothing, hair or fingers can be caught or drawn in at the inlet of the pump.

Never insert fingers or drop any other object into the inlet or outlet.

•Pumping at high inlet pressure may lead to overpressure at the gas ballast valve. Pumped gases or condensate might be expelled if the valve is open. If an inert gas supply is connected to the gas ballast, ensure that its inlet pipeline is not contaminated.

•Pay attention to the safety symbol ”hot surfaces” on the equipment. Hot parts may cause burns if touched. Adopt suitable measures to prevent any danger arising from hot surfaces or electric sparks. Ensure that hot surfaces of the pump do not cause burns. Provide a suitable contact guard if necessary.

•Ensure that the coolant outlet pipe at the waste vapor condenser is always free and that it cannot get blocked.

	Prevent the backpressure of gases and the backflow of
NOTICE
	condensates at the outlet.

page 20 of 76

Check the liquid level in the catchpots or in the collecting flask regularly and drain condensate in time to prevent overfilling. Install a level sensor (see “Accessories”, pg.

46; a CVC 3000 or VNC 2 controller is required for operation) for monitoring, if necessary.

Provide appropriate protective measures to allow for the possibility of failure and malfunction. The protective measures must also allow for the requirements of the respective application.

In case of overload, the motor is shut down by a self-hold thermal cutout in the winding.

Note: Only manual reset is possible. Switch off the pump and disconnect from the power source. Identify and eliminate the cause of failure. Wait approx. five minutes before restarting the pump.

	Maintenance and repair
	In order to comply with laws (occupational, health and
NOTICE
	safety regulations, safety at work law and regulations for
	environmental protection) vacuum pumps, components
	and measuring instruments can only be returned when
	certain procedures (see section “Notes on return to the
	factory”, pg. 71) are followed.
	Take advantage of our service seminars, which put special
	focus on the maintenance and repair of vacuum pumps.
	For details and for the online ”Instructions for repair” man-
	ual see www.vacuubrand.com.
	In normal use, the lifetime of the diaphragms and valves is
	typically 15,000 operating hours. Bearings have a typical
	durability of 40000 h.

Ensure that the pump cannot be operated accidentally. Never operate the pump if covers or other parts of the pump are disassembled.

page 21 of 76

Switch off the pump. Disconnect the electrical power cord and wait two minutes before starting maintenance to allow the capacitors to discharge.

Note: The pump may be contaminated with process chemicals, which have been pumped during operation.

Ensure that the pump is completely decontaminated before maintenance commences.

Take adequate precautions to protect people from the effects of dangerous substances if contamination has occurred. Use appropriate protective clothing, safety goggles and protective gloves.

+Wear parts have to be replaced regularly.

+Never operate a defective or damaged pump.

+Vent the pump before starting maintenance. Isolate the pump and other components from the vacuum system. Allow sufficient cooling of the pump. Separate the pump from the coolant circuit and drain condensate, if applicable.

	Ensure that maintenance is done only by suitably trained
NOTICE
	and supervised technicians. Ensure that the maintenance
	technician is familiar with the safety procedures which re-
	late to the products processed by the pumping system.
	Only dismantle the pump as far as necessary.

The classification II 3G IIC T3 X according to ATEX is only valid for the inner part (wetted part, pumped gas or vapor) of the equipment. The equipment is not suitable for use in external, potentially explosive atmospheres

(environment).

The overall category of the equipment depends on the connected components. If the connected components do not comply with the classification of the VACUUBRAND equipment, the specified category of the

VACUUBRAND equipment is no longer valid.

Vacuum pumps and vacuum gauges in category 3 are intended for connection to equipment in which during normal operation explosive atmospheres 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 during normal operation.

The use of gas ballast or the operation of venting valves is only permitted 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., restrictions 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).

•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 “Technical data”.

After any intervention at the equipment (e.g., repair / maintenance) the ultimate vacuum of the pump has to be checked. Only if the pump achieves its specified ultimate vacuum is the pump’s leak rate low enough to ensure that no explosive atmospheres will occur in the interior of the equipment.

After any intervention at the vacuum sensor, the leak rate of the equipment has to be checked.
