General information

Remove all packing material from the packing box. Re-

move the product from its packing-box and retain all pack-

aging until the equipment is inspected and tested. Re-

move 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 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 deficiencies.

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 de-

sign 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 

NOTICE

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 in-

let temperature is not exceeded. The maximum permit-

ted gas inlet temperature depends on several param-

eters like inlet pressure and ambient temperature (see 

”Technical data”, pg. 24).

+ 

Do not aspirate particles and dust.

+ 

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-

tion of vacuum in vessels designed for that purpose. Any 

other use will automatically invalidate all warranty and li-

ability 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  fitted  with  a  molded  Euro

-

pean IEC plug or a plug suitable for your local electrical 

supply. The cable contains wires color coded as fol-

lows: 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 com-

patibility with system components (e.g., exhaust pipe-

line or exhaust valve) at the outlet.

NOTICE

 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 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 me-

chanical 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 connect-

ed 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 be-

fore 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 cool-

ant valve, it must always be in the supply line of the 

exhaust waste vapor condenser.

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 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.

NOTICE

 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 flames.

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. 24).

➨

 The pumps are 

not suitable

 to pump any of the sub-

stances listed below. 

Do not pump:

NOTICE

page 16 of 74

-  

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 

inflammable 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 

fluids, 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  fluo

-

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 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 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 

inlet and outlet exceeds 16 psi (1.1 bar) at maximum.

Prevent the backpressure of gases and the backflow of 

condensates at the outlet.

Check the liquid level in the catchpots regularly and drain 

condensate  in  time  to  prevent  overfilling.  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. five 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  sufficient  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 

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.

NOTICE

 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 flame, 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 sufficient 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 

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.

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.

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 specified ultimate vacuum, the pump’s leak rate is low enough to en
