- unstable substances

- substances which react explosively under impact

(mechanical stress) without air

- substances which react explosively when being ex-

posed 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 in-

creased temperatures even to the point of exceeding

the maximum permitted temperatures.

• Check the inlet and outlet of the pump, if there is a dan-

ger 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.

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 ap-

propriate collecting and disposal system and take pro-

tective 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 pro-

vider.

+ 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 pro-

tect 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 compat-

ibility 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 sup-

ply, 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 sub-

stances 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 overpres-

sure at the gas ballast valve. Pumped gases or con-

densate 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.

Do not start the pump if the pressure difference between

NOTICE

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 mea-

sures must also allow for the requirements of the respec-

tive 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).

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. 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” man-

ual 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 typi-

cal durability in the range of 10000 to 40000 h depending

strongly on operation conditions including ambient tem-

perature, 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. Re-

place 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.

Allow sufcient cooling of the pump. Separate the pump

from the coolant circuit and drain condensate, if appli-

cable.

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.

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

and

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:

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 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.

Vacuum pumps and vacuum gauges in category 3 are intended for con-

nection at 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.

page 23 of 74

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 protected against shocks from the

outside and against glass splinters in the event of breaking (implo-

sion).

• The equipment is designated for an ambient and gas inlet tempera-

ture 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 ul-

timate 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 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.
