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 18 hours. Any faults, even those which oc-

cur rarely, are identied and can be eliminated immediately.

After completion of the endurance run, every pump is tested, and must

achieve specications 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

Remove the protective caps from the inlet and outlet ports and retain for future use. 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 material 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.

Replace the protective caps, if the equipment is not used immediately. Store the equipment in dry and non-corrosive conditions (see also ”Technical data”, pg. 24).

+ Do not use any damaged equipment.

• Use the mounted handle when moving the pump.

Intended use

+ Do not use the pump or any system parts on humans

or animals.

+ Prevent any part of the human body from coming into

contact with vacuum.

+ Ensure that the individual components are only con-

nected, combined and operated according to their design and as indicated in the instructions for use.

+ Comply with all notes on correct vacuum and electrical

connections; see section ”Use and operation”, pg. 38.

+ 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

page 12 of 74

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).

+ Do not aspirate particles and dust. + Do not pump liquids.

NOTICE

• Ensure that the pump is chemically resistant to the

pumped substances prior to operation.

Use the equipment only as intended, that is, for generation 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

➨ Equipment must be connected only to a suitable elec-

trical 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 result in deadly electrical shock.

The supply cable may be tted with a molded Euro-

pean 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 gen-

erate overpressure at the outlet. Check pressure compatibility with system components (e.g., exhaust pipeline or exhaust valve) at the outlet.

page 13 of 74

+ 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!

+ Always provide a free and pressureless exhaust outlet

to avoid damage to pump valves and risk of bursting of condenser glassware.

+ Check the overpressure safety relief device at the ex-

haust waste vapor condenser at appropriate intervals.

+ Keep the electrical power cord away from heated sur-

faces.

• Provide a rm, level platform for the equipment. Check

that the system which you are going to evacuate is

mechanically stable. Check that all ttings are secure.

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

• Comply with maximum permissible pressures at in- let and outlet and with maximum permissible pres- sure 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 gas or 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.

• 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.

• On pumps with a dual-voltage motor, check that the

voltage selection switch is set correctly. Do not change the setting of the voltage selection switch while the

page 14 of 74

pump is connected to AC power. Unplug the pump before setting the voltage selection switch. Note: If the pump is switched on with wrong voltage selection, the motor may be damaged!

• 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.

NOTICE

Keep a minimum distance of 8 in (20 cm) between the cooling fan and surrounding items (e.g., housing, walls, etc.). 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 required 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.

page 15 of 74

+ Pay attention to the permissible maximum ambient

and gas inlet temperatures (see ”Technical data”, pg.

24).

• Adopt suitable measures in case of differences from

recommended conditions, e.g., using the equipment outdoors, installation in altitudes of more than 3300 ft (1000 m) above mean sea level, conductive pollution or external condensation on the pump.

• Do not operate this product near ames.

NOTICE

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. 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 po-

tentially 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 ex- plosive 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. 22).

➨ The pumps are not suitable to pump any of the sub-

stances listed below.

Do not pump:

page 16 of 74

- 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 inammable without air

- explosive substances.

➨ The pumps are not approved for operation below

ground. Do not operate the pump below ground.

+ The pumps are not suitable for pumping dust. Do not pump dust.

• Do not pump substances which may form deposits in- side 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. 52). 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 recom-

mend 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 17 of 74

Safety during operation

➨ Adopt suitable measures to prevent the release of dan-

gerous, toxic, explosive, corrosive, noxious or polluting

uids, 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 for-

mation 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 with inert gas 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.

+ Never aspirate liquids or dust into the pump.

+ Make sure that the exhaust pipeline cannot become

blocked.

+ Check the overpressure safety relief device at the ex-

haust 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 uo-

page 18 of 74

roelastomers). Use appropriate protective clothing and safety goggles.

+ 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.

The CE mark or the cTÜVus mark may be voided if not

using original manufacturer’s spare parts.

+ 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 ngers can

be caught or drawn in at the inlet of the pump. Never

insert ngers 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

page 19 of 74

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.

NOTICE

Do not start the pump if the pressure difference between inlet and outlet exceeds 16 psi (1.1 bar) at maximum.

Prevent the backpressure of gases and the backow of

condensates at the outlet.

Check the liquid level in the catchpots regularly and drain

condensate in time to prevent overlling. Install a level

sensor (see ”Accessories”, pg. 48) 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 elimi-

nate the cause of failure. Wait approx. ve minutes before

restarting the pump.

• Note: In case of supply voltage below 100V, the lock of the cutout might be impaired and the pump may

restart on its own after sufcient cooling down. Take

appropriate precautions, if an automatic restart of the pump may lead to a dangerous situation (e.g., switch off the pump and disconnect from the power source).

In order to comply with laws (occupational, health and 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. 67) 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” manual see www.vacuubrand.com.

In case of normal wear, the lifetime of the diaphragms and valves is > 10000 operating hours. Bearings have a typical durability of 40000 h. Motor capacitors have a typical durability in the range of 10000 to 40000 h depending strongly on operation conditions including ambient temperature, humidity or load.

➨ Ensure that the pump cannot be operated acciden-

tally. Never operate the pump if covers or other parts of the pump are disassembled.

➨ Switch off the pump. Disconnect the electrical pow-

er cord and wait two minutes before starting mainte-

nance 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.

page 21 of 74

+ Wear parts have to be replaced regularly. + Never operate a defective or damaged pump.

+ Check every motor capacitor regularly by measuring

its capacity and estimating its time in operation. Replace old capacitors early enough to prevent a failure in operation. If an old motor capacitor fails, the capacitor

may get hot. It may even melt or emit a ame, which

could be dangerous for persons and equipment in the vicinity. The capacitors have to be replaced by an

electrician.

+ Vent the pump before starting maintenance. Isolate the

pump and other components from the vacuum system.

NOTICE

Allow sufcient 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 and supervised technicians. Ensure that the maintenance technician is familiar with the safety procedures, which relate to the products processed by the pumping system. Only dismantle the pump as far as necessary.

VACUUBRAND equipment bearing mark (see rating plate)

X see manual

For equipment labelled with „ X see manual“ the following classica- tion according to Directive 94/9/EC (ATEX) is valid:

Internal Atm. only, Tech. File Ref.: VAC-EX01.

The classication 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 compo-

nents. If the connected components do not comply with the classication of the VACUUBRAND equipment, the specied category of the VACU-

UBRAND equipment is no longer valid.

II 3G IIC T3 X,

Vacuum pumps and vacuum gauges in category 3 are intended for connection at 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.

page 23 of 74

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 protected against shocks from the

outside and against glass splinters in the event of breaking (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 valid, 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 specied ultimate vacuum, the pump’s leak rate is 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.

Attention: This manual is not available in all languages of the EU. The user must not operate the device if he does not understand this manual. In this case a technically correct translation of the complete manual has to be available. The manual must be completely read and understood before operation of the device and all required measures must be applied.

Use and operation

Installing a pump in a vacuum system

➨ If dangerous or polluting uids could be released at the

outlet, install an appropriate system to catch and dis-

pose of those uids.

+ Connect a gas-tight exhaust line at the pump outlet if

necessary. Always vent exhaust gases appropriately (e.g., into a fume hood).

+ Never block the gas outlet. The exhaust line must al-

ways be free of obstructions (no back pressure) to en-

page 38 of 74

sure an unimpeded discharge of gas. The cross-section of the outlet tubing must be at least the size of the pump’s exhaust connection.

+ Particles and dust must not be aspirated. If necessary,

you must install appropriate lters. You must ensure their suitability concerning gas ow, chemical resis-

tance and resistance to clogging prior to use.

+ Make sure ventilation is adequate, especially if the pump

is installed in an enclosure, or if the ambient temperature is elevated. Provide external ventilation, if necessary.

• Reduce the transmission of vibration. Prevent mechanical load due to rigid pipelines. Insert elastic hoses or

exible elements as couplings between the pump and

rigid pipes. Note: Flexible elements will compress or

atten when evacuated if not designed for use under

vacuum.

• Hose connections at the pump inlet must always be

gas tight.

• A power failure may cause accidental ventilation of the

pump, especially if the gas ballast valve is open . If this constitutes a potential source of danger, take appropriate safety measures.

page 39 of 74

• 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.

• Pump with dual-voltage motor: Check that the volt- age selection switch at the terminal box is positioned correctly. Check every time before starting the pump.

Note: If the pump is switched on with wrong voltage

selection, the motor may be damaged!

Change the selection at the voltage selection switch

only, if the pump is unplugged from the power source.

Voltage selection switch:

NOTICE

1. Disconnect the electrical power cord.

2. Use a screw driver to adjust the voltage selection switch at the terminal box of the pump to the

supply voltage:

”115” corresponds to 90-126 V and ”230” corresponds to 180-253 V.

voltage selection switch

Keep a distance of minimum 8 in (20 cm) between fan and adjacent equipment or casework. Use connecting hoses with large diameter and keep them

as short as possible to avoid ow losses. Locate the pump

as closely as possible to the application. Always install outlet tubing descending from the pump to

avoid backow of condensate towards the pump.

Use a suitable valve to isolate the pump from the vacuum application. This is to allow the pump to warm up before pumping condensable vapors and to clean the pump after use before it is switched off. When assembling, ensure vacuum-tightness. After assembly, check the whole system for leaks. Secure hose connections at the pump appropriately, e.g., with hose clamps, to protect against accidental detachment.

page 40 of 74

To reduce pump noise emanating from the pump exhaust port, connect an exhaust hose or use a silencer (see ”Accessories”, pg. 48).

Separator (inlet) and exhaust waste vapor condenser (outlet)

Assembling the hose nozzle with union nut:

➨ Take the hose nozzle with attached compression fer-

rule and union nut out of the catchpot and put onto inlet connection (version 2 AK: onto inlet and outlet connections).

➨ Tighten the union nut by hand until you can feel the

stop. Then tighten an additional 1/4 rotation with an

overpressure safety relief device (11)

catchpot at outlet (9)

catchpot at inlet (9)

outlet (gas!) (2)

open-ended wrench (size 17mm) for nal installation.

Catchpots:

The catchpot at the inlet protects against droplets and particles from entering the pump. + Enhances lifetimes of diaphragms and

valves.

+ Improves vacuum performance in applica-

tions with condensable vapors. Both catchpots are coated with a protective layer to protect against shattering in case of breakage or implosion. ➨ Assemble the catchpots at the inlet and at

the outlet using joint clips.

Exhaust waste vapor condenser:

(13)

(12)

➨ Assemble the hose nozzles for coolant inlet

(12) and coolant outlet (13) tubing at the ex-

haust waste vapor condenser. The exhaust waste vapor condenser enables

an efcient condensation of the pumped vapors

at the outlet.

+ No backow of condensates. + Controlled recovery of condensates. + Close to 100% solvent recovery. + The isolation cover protects against glass

page 41 of 74

splinters in case of breakage, acts as ther-

mal isolation to avoid condensation of hu-

midity and is intended to absorb shocks.

➨ Attach the tubing of the coolant circuit to the respective

hose nozzles (hose nozzles for tubing I.D. 1/4”-5/16” (6-8 mm), see image) at the waste vapor condenser.

NOTICE

Check all hose connections prior to starting operation of the cooling system. Secure coolant hoses at the hose nozzles (e.g., with hose clamps) to prevent their accidentally slipping off.

➨ Prevent the discharge of dangerous gases and vapors

to the surrounding atmosphere. If appropriate, connect the exhaust line to a suitable treatment system.

+ Never block the gas outlet ((2) hose nozzle for tubing

I.D. 3/8” (10 mm)). The exhaust hose has always to be unobstructed and without back pressure to enable an unhindered discharge of gases and protect the pump valves from damage.

• Note: Install the hoses of the cooling system in a way

to avoid the ow / dripping of condensed water onto the

pumping unit (especially cables and electronic parts, see also IP degree of protection, ”Technical data”, pg.

24.

• Ensure that the coolant outlet tubing is always unob- structed and that it cannot get blocked.

• Maximum permissible coolant pressure at the exhaust

waste vapor condenser: 87 psi (6 bar) absolute. Outlet

ow must always be unhindered.

• Comply with the maximum permissible coolant pres-

sures of additional components in the coolant circuit (e.g., coolant valve).

• Avoid overpressure in the coolant circuit (e.g., caused

by blocked or squeezed coolant hoses).

• Only install the optional coolant valve in the supply line

of the exhaust waste vapor condenser.

page 42 of 74

During operation

➨ Vent and dispose of potentially dangerous gases or

vapors at the outlet of the pump appropriately.

+ Due to the high compression ratio, the pump might gen-

erate overpressure at the outlet. Check pressure compatibility with system components (e.g., exhaust tubing or exhaust valve) at the outlet. Ensure that the pump outlet is neither blocked nor restricted.

+ Maximum ambient temperature: 104 °F (40 °C) Check the maximum temperatures, if installing the

pump in a cabinet or a housing. Make sure ventilation

NOTICE

is adequate, especially if the ambient temperature is elevated.

• If the pump is installed at an altitude of more than 3300

ft (1000 m) above mean sea level, check compatibility with applicable safety requirements, especially IEC

60034. There is a risk of the motor overheating due to

insufcient cooling.

• Check compatibility with the maximally permitted

pressure at outlet and the maximum pressure difference between inlet and outlet ports.

Do not start the pump if the pressure difference between inlet and outlet ports exceeds max. 16.0 psi (1.1 bar).

Attempts to start the pump at higher pressure difference may cause stalling and damage of the motor.

If pumping condensable vapors (water vapor, solvents, etc.), let the pump run with gas ballast to help purge any condensation in the pump.

Prevent internal condensation, transfer of liquids or dust. The diaphragms and valves will be damaged, if liquids are

pumped in signicant amounts.

Check the pump regularly for external soiling and depos-

page 43 of 74

its. Clean the pump if necessary to avoid an increase of the pump’s operating temperature.

Operation with silencer (optional) at the outlet: Operating the pump at a high inlet pressure or pumping dusty gases for a long time may cause clogging of the silencer. Check the silencer regularly and replace if necessary.

In case of overload, the motor is shut down by a self-hold

thermal circuit breaker in the winding. Note: Only a manual reset is possible. Switch off the

pump and disconnect the electrical power cord. Identify

and eliminate the cause of failure. Wait approximately ve

minutes before restarting the pump.

NOTICE

• Note: In case of supply voltage below 100V, the lock of the breaker may not latch and the pump might restart on its own after sufcient cooling. Take appropriate precautions, if an automatic restart of the pump may lead to a dangerous situation.

A warm up period (approximately 15 min.) is required to

ensure that the rated ultimate vacuum and pumping speed are attained. Avoid overheating (e.g., due to hot process gases).

Pumps with ow control diaphragm valve:

Use the ow control diaphragm valve (14) at the pump inlet to control the pumping speed. Open ow control

diaphragm to pump down. ➨ Opening the ow control diaphragm: Turn counterclock-

NOTICE

wise. Do not attempt to open the valve further than when

resistance is rst encountered.

➨ Closing: Turn clockwise. Close ow control diaphragm

valve slightly hand-tight. Further tightening will not increase sealing of the valve, and may lead to damage.

Note: Over-tightening or -loosening may damage the diaphragm or the valve seat, and the valve may not close properly thereafter. Replace diaphragm in case of leaks.

page 44 of 74

Important notes regarding the use of gas ballast

Gas ballast is a continuous purge to keep the pump’s interior as clean as possible and to reduce the possibility of condensation inside the pump.

➨ Air and pumped media might react inside the pump or

at the outlet of the pump and form hazardous or explosive mixtures, when you use air rather than inert gas

for the gas ballast. This constitutes a risk of signicant

damage to equipment and/or facilities, a risk of personal injury or even loss of life.

NOTICE

+ Make sure that air/gas intake through the gas ballast

valve can never lead to hazardous, explosive or otherwise dangerous mixtures. If in doubt, use inert gas.

To reduce condensation in the pump, do not pump vapor

before the pump has reached its operating temperature. Open the gas ballast valve when pumping condensable vapors. Turn gas ballast cap to open valve.

For condensable vapors (water vapor, sol- vents, etc.):

gas ballast

(3)

(open)

- The gas ballast valve is open if the arrow on the gas ballast cap is pointing towards the labelling ”GB”.

- With gas ballast valve open, the ultimate vacuum will be reduced.

- Use inert gas for gas ballast to avoid the formation of

explosive mixtures. A special adapter tting is needed

to connect an inert gas supply line (see ”Accessories”, pg. 48). This adapter replaces the standard gas ballast cap and allows for an inert gas line to be connected via a KF DN 16 small ange at a maximum supply pressure of 17.5 psi (1.2 bar) absolute.

- Close the gas ballast valve by turning the cap 180°.

page 45 of 74

In case of low boiling solvents (when the formation of condensate is unlikely), the use of gas ballast might be unnecessary. Operating the pump without gas ballast increases the solvent recovery rate at the exhaust waste vapor condenser.

Important notes concerning the operation of the exhaust waste vapor condenser

➨ Connect the exhaust to a suitable treatment system to

prevent the discharge of dangerous gases and vapors to the surrounding atmosphere.

+ Never block the gas outlet ((2) hose nozzle for tubing

I.D. 3/8” (10 mm)). The exhaust hose must always be unobstructed and without back-pressure to enable an unhindered discharge of gases.

+ Check the overpressure safety relief device (11) at the

exhaust waste vapor condenser (10) regularly; replace if necessary. Check especially for deterioration, coalescence and cracks.

• Ensure that the coolant outlet hose is always free and that it cannot get blocked.

• Maximum permissible coolant pressure at the exhaust

waste vapor condenser: 87 psi (6 bar) absolute

• Comply with the maximum permissible coolant pressures of additional components in the coolant circuit

NOTICE

(e.g., coolant valve).

• We strongly recommend installing an optional coolant

valve (see ”Accessories”, pg. 48) in the supply line of the exhaust vapor condenser to save water and reduce the risk of water spill.

• Avoid overpressure in the coolant circuit (e.g., caused

by blocked or kinked coolant hoses).

In case of condensation: Check the liquid level in both catchpots (9) during operation. Check the liquid level in both catchpots regularly. Do not allow the catchpots to

page 46 of 74

overll. Drain catchpots in time to avoid overow. Install a

level sensor (see ”Accessories”, pg. 48) for monitoring, if necessary (VACUUBRAND controller CVC 3000 or VNC 2 is required). The maximum liquid level is at approximately 80% of the

total lling level to avoid problems when removing the

catchpots.

Permissible range of coolant temperature at the exhaust waste vapor condenser: 5 °F to 68 °F (-15°C to +20°C)

Check hose connections prior to starting operation of the cooling system.

NOTICE

Check coolant hoses regularly during operation.

Removing the catchpots:

Catchpot at outlet: Remove joint clip. Remove catchpot and drain condensate.

Catchpot at inlet: Admit air or inert gas (via the pump inlet) to restore atmospheric pressure in the catchpot before attempting removal.. Remove joint clip. Remove catchpot and drain condensate.

Reattach drained catchpots.

+ Important: Comply with regulations when disposing

of solvents/condensates. Recycle if possible; purify if contaminated.

page 47 of 74

Shutdown & storage

The pump can be switched off under vacuum.

NOTICE

Short-term:

Has the pump been exposed to condensate? Allow the pump to continue to run at atmospheric pressure for a few minutes. Has the pump been exposed to media which may damage the pump materials or form deposits? Check and clean pump heads if necessary.

Long-term:

Take measures as described above regarding short-term shutdown. Separate the pump from the application. Close inlet and outlet ports (e.g., with transport caps). Close the gas ballast valve. Drain catchpots. Store the pump under dry conditions.

Replacing diaphragms and valves

+ Please read section ”Replacing diaphragms and valves” com-

pletely before starting maintenance.

The pictures may show other versions of pumps. This does not change

the method of replacing diaphragms and valves.

➨ Never operate the pump if covers or other parts of

the pump are disassembled.

➨ Before starting maintenance, disconnect the electri-

cal power cord. Wait two minutes after isolating the

equipment from AC power to allow the capacitors to discharge.

➨ Ensure that the pump cannot be operated accidentally. ➨ Note: The pump might be contaminated with the pro-

cess chemicals that have been pumped during operation. Ensure that the pump is decontaminated before maintenance.

➨ Avoid the release of pollutants.

+ Never operate a defective or damaged pump.

+ Take adequate precautions to protect people from the

effects of dangerous substances that may have contaminated the pump and may be released upon disassembly. Ensure that the maintenance technician is familiar with the safety procedures which relate to the products processed by the pumping system.

Use appropriate protective clothing, safety goggles and

protective gloves.

+ Check every motor capacitor regularly by measuring its

capacity and estimating its service life. Replace old capacitors early enough to prevent a failure. The capacitors must be replaced by a trained electrician.

+ Allow sufcient cooling of the pump before starting

maintenance. Drain condensate, if applicable.

+ Vent the pump and isolate it from the vacuum sys-

tem before you start maintenance.

page 53 of 74

NOTICE

Ensure that maintenance is done only by suitably trained and supervised technicians.

The valves and diaphragms as well as the motor capacitors are wear parts. If the rated ultimate vacuum is no longer achieved or in case of increased noise level, the pump interior, the diaphragms and the valves must be cleaned and the diaphragms and valves must be checked for cracks or other damage.

All bearings are encapsulated and are lled with long-life

lubricant. Under normal operating conditions, the drive system is maintenance free.

In demanding circumstances, it may be efcient to

check and clean the pump heads on a regular basis. In normal use, the lifetime of the diaphragms and valves is more than 10,000 operating hours.

- Prevent internal condensation, transfer of liquids or dust. The diaphragms and valves will be damaged if

liquid is pumped in signicant amount.

- Carry out maintenance frequently if the pump is exposed to corrosive media or in case of deposits.

- Regular maintenance will improve the lifetime of the pump and also protect both users and the environment.

➨ Assemble catchpots (9) with joint clips.

page 64 of 74

Checking the ultimate vacuum

➨ 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 specied ultimate vacuum, the pump’s leak rate is low

enough to ensure that no explosive atmospheres will occur in the interior of the equipment.

If the pump does not achieve the ultimate vacuum:

- Whenever the diaphragms and valves have been replaced, a break-in period of several hours is required before the pump achieves its ultimate vacuum.

- In case of an unusual noise, switch off pump immediately and check clamping disc positions.

If the specied ultimate vacuum is not achieved, and if this does not

change after the break-in period: Check hose connectors at pump heads for leaks. If necessary recheck valve seats and pump chambers.
