Safety information!
General information
NOTICE
☞ Read and comply with this manual before installing or operating the equipment.
☞ Transport the pump at the provided handle or the recessed grips.
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.
Intended use
☞ The pump and all system parts must not be used on humans or animals.
☞ Prevent any part of the human body from coming into contact with vacuum.
☞ Ensure that the individual components are only connected, combined and operated according to their design and as indicated in the instructions for use.
☞ Comply with notes on correct vacuum and electrical connections, see section
”Use and operation”.
• The pumps are designed for ambient temperatures during operation between
+10°C and +40°C. Check the maximum temperatures if installing the pump in a
cabinet or a housing and make sure ventilation is adequate. Install an external
automatic ventilation system if necessary. If pumping hot process gases make
sure that the maximum permitted gas inlet temperature, which depends on several parameters like inlet pressure or ambient temperature (see ”Technical data”),
is not exceeded.
• Particles and dust must not be aspirated.
NOTICE
Use the equipment for the intended use only, i.e. for generation of vacuum in vessels designed for that purpose.
Setting up and installing the equipment
➨ Equipment (pumps with AC motor) must be connected only to a suitable fused
and protected electrical supply and a suitable earth point, provide slow-blow
fuse according to voltage supply (see ”Technical data”). 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.
☞ Due to the high compression ratio of the pumps, pressure at the outlet port might
be generated being higher than the maximum permissible pressure compatible
with the mechanical stability of the system.
☞ Do not permit any uncontrolled pressurizing (e. g. 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. Risk of bursting!

the validity of this document with respect to his product. Manual-no.: 999098 / 24/02/2009
page 5 of 35
☞ Always provide a free and pressureless exhaust pipeline.
☞ Ensure that the coolant outlet pipeline is always free and that it cannot get
blocked. Install a optional coolant valve always in the supply line of the exhaust
waste vapour condenser only.
☞ Secure coolant hoses at the hose nozzles (e.g. with hose clip) to prevent their
accidental slipping.
☞ Check the overpressure safety relief device at the exhaust waste vapour condenser in appropriate intervals.
• Comply with maximum permissible pressures at inlet and outlet and pressure
differences, see section ”Technical data”. Do not operate the pump with overpressure at the inlet.
• Check that mains voltage and current conform with the equipment (see rating
plate).
• Change the setting of the voltage changeover switch (pump with dual-voltage motor 100-120 V / 200-230 V; 50/60 Hz) only if the pump is separated from mains.
Check that the voltage changeover switch is set correctly. Attention: If the pump
is switched on with wrong voltage selection, the motor might be damaged!
• Avoid overpressure of more than 0.2 bar in case inert gas is connected to the
pump, the gas ballast or to a venting valve.
• Connect pipes gas tight at inlet and outlet of the pump.
• Attention: Flexible elements tend to shrink when evacuated.
• Adopt suitable measures to avoid the flowing of liquids on or into the pump motor
when assembling or disassembling vacuum connections at the pump. Risk of
corrosion and/or short circuit!
NOTICE
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. Ensure a stable position of the pump without any mechanical contact except of the pump feet. Comply
with all applicable safety regulations.
Keep a distance of minimum 20 cm between fan and ambient parts (e.g. housing,
walls, ...). Check fan regularly for dust/dirt, clean if necessary to avoid a cutback of
ventilation.
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).
The diameter of the inlet and outlet pipeline should be at least as large as the diameter of the pump connection pipelines.
Comply with all applicable and relevant safety requirements (regulations and
guidelines), implement the required actions and adopt suitable safety measures.
Ambient conditions
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 IEC 1010 gives in detail
conditions under which the equipment can be operated safely (see also IP degree
of protection).

the validity of this document with respect to his product. Manual-no.: 999098 / 24/02/2009
page 6 of 35
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 bedewing.
Pay attention to the permissible maximum ambient and gas inlet temperatures
(see ”Technical data”).
Operating conditions
➨ The pumps have no approval for operation in or for pumping of potentially
explosive atmospheres.
➨ 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,
- self inflammable substances,
- substances which are inflammable without air and
- explosive substances.
• 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 excessing the maximum permitted temperatures!
• If there is a danger of formation of deposits in the pump chamber (check inlet
and outlet of the pump), inspect the pump chambers regularly and clean if necessary.
• The pumps are not suitable for pumping dust and have no approval for operation below ground.
NOTICE
If pumping different substances, it is recommended to purge the pump with air or
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 and with the pump materials.
Take into consideration interactions and chemical reactions of the pumped
media. Ensure that the materials of the wetted parts are compatible with the pumped
substances, see section ”Technical data”.
Safety during operation
➨ Adopt suitable measures to prevent the release of dangerous, toxic, explosive,
corrosive, noxious or polluting fluids, vapours and gases. In case install an appropriate collecting and disposal system and take protective action for pump and
environment.
➨ Prevent any part of the human body from coming into contact with vacuum.
➨ The user must take suitable precautions to prevent any formation of explosive
mixtures in the expansion chamber or at the outlet. In case of e.g. a diaphragm
crack, mechanically generated sparks, hot surfaces or static electricity may ignite
these mixtures. Use inert gas for gas ballast or venting if necessary.
➨ Potentially explosive mixtures at the outlet of the pump have to be drained appropriately, sucked off or diluted with inert gas to non-explosive mixtures.

the validity of this document with respect to his product. Manual-no.: 999098 / 24/02/2009
page 7 of 35
☞ Pay attention to the symbol ”hot surfaces” on the equipment. Adopt suitable
measures to prevent any danger arising from the formation of hot surfaces or
electric sparks. Provide a suitable protection against contact if necessary.
☞ Pumping at high inlet pressure may lead to overpressure at the gas ballast
valve. Pumped gases or condensate might be pushed out in case the valve is
open. If an inert gas supply is connected, ensure that the inlet pipeline is not contaminated.
• Comply with applicable regulations when disposing of chemicals. Take into consideration that chemicals may be polluted.
Take adequate precautions to protect people from the effects of dangerous substances (chemicals, thermal decomposition products of fluoroelastomers), wear
appropriate safety-clothing and safety glasses.
• Use only genuine spare parts and accessories. Otherwise safety and performance of the equipment as well as the electromagnetic compatibility of the equipment might be reduced.
Possibly the CE mark or the cTÜVus mark become void if not using OEM spare
parts.
• Failure of the pump (e.g. due to power failure) or of connected components,
parts of the supply or change of parameters must not lead to a critical dangerous
situation under any circumstances. In case of diaphragm cracks or leaks in the
manifold pumped substances might be released into the environment or into the
pump housing or motor. Comply especially with notes on operation and use and
maintenance.
• Due to the residual leak rate of the equipment, there might be 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.
NOTICE
Check liquid level in both catchpots regularly and drain condensate in time.
Do not start the pump if the pressure difference between inlet and outlet port exceeds 1.1 bar at maximum.
Prevent the backpressure of gases and the backflow of condensates.
Never suck liquids or dust into the pump.
Provide appropriate protective measures (i.e. precautions which allow for the requirements of the respective application) even for the case of failure and malfunction.
Pumps with 115 V motor, 230 V motor and dual-voltage motor:
In case of overload the motor is shut down by a self-hold thermal cutout in the
winding.
Attention: Reset possible only manually. Switch off the pump or isolate the equipment from mains. Identify and eliminate the cause of failure. Wait approx. five minutes before restarting the pump.
Attention: In case of supply voltage below 100V, the lock of the cutout might be
restricted and the pump might restart on its own after sufficient cooling down. Take
suitable precautions, if an automatic restart of the pump may lead to a critical dangerous situation.

the validity of this document with respect to his product. Manual-no.: 999098 / 24/02/2009
page 8 of 35
Pumps with 24 V DC voltage:
The motor is protected by a temperature sensor at the circuit board: Current
limitation if the temperature at the circuit board is higher than 70°C, switching off the
pump if the temperature is higher than 85°C. In case of blockade of the motor (after
10 attempts to start-up) the pump is switched off.
If the pump is switched off due to safety measures, manual reset is necessary. Isolate
the pump from mains. Eliminate the cause of failure before restarting the pump.
The A-weighed emission sound pressure level of the pump does not exceed 70
dB(A). Measurement according to EN ISO 2151:2004 and EN ISO 3744:1995 with
standard silencer or exhaust tube at outlet.
Maintenance and repair
Wear parts have to be replaced regularly. 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 the operation conditions like ambient temperature, humidity or load.
• Check every capacitor regularly by measuring its capacity and estimating its operation time. Exchange old capacitors early enough to prevent a failure. If an
overaged motor capacitor fails it might get hot and even melt and may cause a
flame to form which could be dangerous for persons and equipment in the
vicinity. The capacitors have to be replaced by an electrician.
➨ Isolate equipment from mains and wait two minutes before starting maintenance to allow the capacitors to discharge.
☞ Ensure that the pump cannot be operated accidentally. Never operate the
pump if covers or other parts of the pump are disassembled. Never operate
a defective or damaged pump.
☞ Attention: The pump might be contaminated with process chemicals which have
been pumped during operation. Ensure that the pump is decontaminated before
maintenance and take adequate precautions to protect people from the effects of
dangerous substances if contamination has occurred.
• Before starting maintenance vent the pump, isolate the pump and other components from the vacuum system. Allow sufficient cooling of the pump. 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.
In order to comply with law (occupational, health and safety regulations, safety at
work law and regulations for environmental protection) vacuum pumps, components
and measuring instruments returned to the manufacturer can be repaired only when
certain procedures (see section ”Notes on return to the factory”) are followed.

Only pumps with dual-voltage motor!
Voltage selection switch:
Change the selection at the voltage changeover switch only if the pump is
separated from mains.
Use a screw driver to adjust the supply voltage on the voltage changeover switch:
”115” corresponds to 100-120V and
”230” corresponds to 200-230V.
Pumps with dual-voltage motor:
☞ Check that the voltage changeover switch is correctly positioned.
Attention: If the voltage is not correctly selected, the motor can be damaged if the pump is switched on. Change the selection at the voltage
changeover switch only if the pump is separated from mains.
Replacing the motor fuse (only MD 1C C/US)
➨ Unscrew the fuse carrier at the side of the pump using a
screw driver.
➨ Replace the defective fuse by a fuse of the same type
(2.5 AT) and reassemble fuse carrier with fuse to the
pump.

Controlling the MD 1C VARIO-SP
Connecting the control line:
1: +24V
2: GND (24V)
3: Signal (depending on selection of the signal input:
0V - 10V for voltage input, 5V - max. 24V for PWM)
4: GND signal
Setting the motor speed externally via PWM (factory-set):
PWM (5V - max. 24V), frame frequency: >100 Hz, <1.5 kHz
Minimum motor speed 350 rpm: at 25% PWM
Maximum motor speed 2200 rpm: at 75% PWM
e.g., at a frame frequency of 100 Hz and 25% PWM: pulse-width 2.5 ms
Factory-set, the pump is designed for operation with a control signal; i.e. without a control signal, the pump does not start!
To operate the pump without a control signal, change the settings on the circuit board (see below)!
Selecting the control signal input:
To select the control signal input, use the slide switch, the DIP switch and/or the trimming potentiometer
on the circuit board. For that purpose, loosen the screw fixing the cover with the cable duct. Slide the
cover carefully, and only as far as necessary, aside.

Internal setting of the motor speed via trimming potentiometer:
☞ Supply the pump with the required supply voltage of 24V DC.
☞ For internal setting of the motor speed, set the DIP switch to positions ”on / on” (programming mode).
Adjusting the motor speed with the trimming potentiometer:
Turning the trimming potentiometer to the right: decreasing motor speed (minimum 350 rpm);
Turning the trimming potentiometer to the left: increasing motor speed (maximum 2200 rpm).
Maximum number of motor speed settings: 50.
☞ In case, separate pump from voltage supply.
Notes regarding the motor speed
Pumping at high motor speed increases the pumping speed of the pump. Ensure sufficient cooling
of the pump!
Pumping at low motor speed increases the ultimate vacuum of the pump and also the lifetime of
diaphragms and valves!

• Connection lines at the pump inlet have to be gas tight. Particles and dust must
not be aspirated, the user has to provide appropriate filters if necessary. The user
must ensure their suitability concerning gas flow, chemical resistance and safeness against clogging prior to use.
• Connect an exhaust line gas tight at the pump outlet if necessary. Always dispose
of exhaust gases appropriately (e.g. into a fume hood). If there is risk of release of
dangerous or polluting fluids, install an appropriate system to catch and dispose
of those fluids.
• Reduce the transmission of vibration and prevent mechanical load due to rigid
pipelines. Insert elastic hoses or flexible elements as couplings between the pump
and rigid pipes. Attention: Flexible elements tend to shrink when evacuated.
• The gas outlet must never be blocked. The exhaust line has always to be free
(pressureless) to ensure an unimpeded discharge of gas.
• Especially if the gas ballast valve is open, a power failure may cause accidental
ventilation of the pump. In case this constitutes a potential source of danger, take
appropriate safety measures.
• Make sure ventilation is adequate especially if the pump is installed in a housing
or if the ambient temperature is elevated. Provide external ventilation if necessary. Keep a distance of minimum 20 cm between fan and ambient parts.
• Check that mains voltage and current conform with the equipment (see rating
plate).
Pump with dual-voltage motor: Check that the voltage changeover switch is
positioned correctly.
Attention: If the pump is switched on with wrong voltage selection, the motor
may be damaged!
Before starting the pump, check that the voltage changeover switch is correctly
positioned.
Change the selection at the voltage changeover switch only if the pump is
separated from mains.
NOTICE
Voltage changeover switch:
Change the selection at the voltage changeover switch only if the pump
is separated from mains.
Use a screw driver to adjust the supply voltage on the voltage changeover switch:
voltage
”115” corresponds to 90-126 V and
changeover
”230” corresponds to 180-253 V.
switch
Avoid throttling losses by using connecting pipes with large diameter and by keeping
them as short as possible.
Install outlet pipelines always falling to avoid backflow of condensate towards the
pump.
Use of a suitable valve to isolate the pump from the vacuum system is recommended
to allow the pump to warm up before pumping condensable vapours or to clean the
pump 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 against accidental detaching.

Separator (inlet) and exhaust waste vapour condenser (outlet)
Assembling the hose nozzle with union nut at the inlet:
➨ Take the hose nozzle with attached compression ferrule and union nut out of the
round bottom flask and put onto inlet connection.
➨ Tighten the union nut by hand until you can feel the stop. Then tighten an additional 1/4 rotation with an open-ended wrench size 17 for final installation.
Catchpots:
The catchpot at the inlet prevents droplets and particles from
entering the pump.
☞ Lifetimes of diaphragms and valves are enhanced.
☞ Improves vacuum in case of condensation.
Both catchpots are coated with a protective layer to prevent
disintegration in case of breakage or implosion.
➨ Assemble the catchpots at the inlet and at the outlet using
joint clips.

NOTICE
Exhaust waste vapour condenser:
➨ Assemble hose nozzles for coolant inlet (1) and coolant
outlet (2) pipelines at the exhaust waste vapour condenser.
The exhaust waste vapour condenser enables an efficient
condensation of the pumped vapours at the outlet.
☞ No backflow of condensates.
☞ Controlled recovery of condensates.
☞ Next to 100% solvent recovery.
☞ The isolation cover protects against glass splinters in case
of breaking, acts as thermal isolation to avoid condensation of humidity and is intended to absorb shocks.
Attach the pipelines of the coolant circuit to the respective hose nozzles (hose nozzles 6-8 mm, see image) at the waste vapour condenser. Check hose connections
prior to starting operation of the cooling system.
Secure coolant hoses at the hose nozzles (e.g. with hose clip) to prevent their accidental slipping.
• The gas outlet (hose nozzle 10 mm) must not be blocked. The exhaust pipeline
has always to be free and pressureless to enable an unhindered discharge of
gases.
• If necessary connect the exhaust to a suitable treatment plant to prevent the discharge of dangerous gases and vapours to the surrounding atmosphere.
• Attention: Install hoses of the cooling system in a way to avoid flow / dropping of
condensed water onto the pumping unit (especially cables and electronic parts).
• Ensure that the coolant outlet pipeline is always free and that it cannot get
blocked.
• Maximum permissible coolant pressure at the exhaust waste vapour condenser:
6 bar (absolute). Backflow always pressureless.
• Comply with the maximum permissible coolant pressures 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).
• Install an optional coolant valve always in the supply line of the exhaust waste
vapour condenser only.

During operation
• Maximum ambient temperature: 40 °C
• Make sure ventilation is adequate especially if the pump is installed in a housing
or if the ambient temperature is elevated.
• Potentially dangerous gases or vapours at the outlet of the pump have to be
drained and disposed of appropriately.
• Due to the high compression ratio of the pumps, the pressure at the outlet port
might get higher than the maximally permitted pressure compatible with the mechanical stability of the system. Ensure that the pump outlet is not blocked or
restricted.
NOTICE
If pumping condensable vapours (water vapour, solvents, ....), let the pump run with
gas ballast to reduce condensation in the pump.
If the pump is installed in altitudes of more than 1000 m above mean sea level check
compatibility with applicable safety requirements, especially IEC 60034 (motor might
overheat due to insufficient cooling).
Do not start the pump if the pressure difference between inlet and outlet ports
exceeds max. 1.1 bar. Attempts to start the pump at higher difference may cause
blockade and damage of the motor.
Check compatibility with maximally permitted pressure at outlet and maximum
pressure difference between inlet and outlet ports.
Prevent internal condensation, transfer of liquids or dust. The diaphragms and valves
will be damaged, if liquids are pumped in significant amounts.
Check the pump regularly for external soiling and deposits, clean if necessary to
avoid an increase of the pump‘s operating temperature.
Pumps with 115V motor, 230V motor and dual-voltage motor:
In case of excess temperature, the motor is shut down by a thermal cutout in the
winding.
Attention: Reset possible only manually. Switch off the pump or isolate the equipment from mains. Determine and eliminate the cause of failure. Wait approx. five
minutes before restarting the pump.
Attention: In case of supply voltage below 100V, the lock of the cutout might be
restricted and the pump might restart on its own after sufficient cooling down. Take
suitable precautions, if an automatic restart of the pump might lead to a dangerous
situation.
Pumps with 24 V DC voltage: The motor is protected by a temperature sensor at
the circuit board (current limitation if the temperature at the circuit board is higher
than 70°C)
A warm up period (approx. 15 min.) is required to ensure that the rated ultimate
vacuum, pumping speed, and vapour pumping rate are attained. Avoid high heat supply (e. g. due to hot process gases).
Attention: Important notes regarding the use of gas ballast
➨ When using air rather than inert gas, risk of significant damage to equipment and/
or facilities, risk of personal injury or even loss of life exists due to the formation
of hazardous and/or explosive mixtures if air and pumped media react inside or
at the outlet of the pump.
☞ Make sure that air/gas inlet through the gas ballast valve never leads to hazardous, explosive or otherwise dangerous mixtures. If in doubt, use inert gas.

gas
ballast
For condensable vapours (water vapour, solvents, ...):
☞ Do not pump vapour before pump has reached its operating temperature. Open gas ballast valve when pumping
condensable vapours.
☞ The gas ballast valve is open, if the arrow on the gas ballast cap shows away from the pump (MD 1C / MD 1C
VARIO‑SP), respectively to the pump (MD 1C + AK + EK)
or away from the inlet (MZ 1C).
☞ With gas ballast valve open, the ultimate vacuum will be
reduced.
☞ Use inert gas for gas ballast to avoid the formation of explosive mixtures.
☞ Close the gas ballast valve by turning the cap 180°.
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 vapour condenser.
Attention! Notes concerning the operation of the exhaust waste vapour condenser:
☞ The gas outlet (hose nozzle 10 mm) must not be blocked. The exhaust pipeline
has always to be free and pressureless to enable an unhindered discharge of
gases.
☞ Connect the exhaust to a suitable treatment plant to prevent the discharge of
dangerous gases and vapours to the surrounding atmosphere.
☞ Ensure that the coolant outlet pipeline is always free and that it cannot get
blocked.
• Check the overpressure safety relief device at the exhaust waste vapour condenser regularly, replace if necessary. Check especially for conglutination and
cracks.
• Maximum permissible coolant pressure at the exhaust waste vapour condenser:
6 bar (absolute)
• Comply with the maximum permissible coolant pressures of additional components in the coolant circuit (e.g coolant valve).
• Install optional coolant valves always in the supply line of the waste vapour condenser only.
• Avoid overpressure in the coolant circuit (e.g. caused by blocked or squeezed
coolant hoses).
• In case of condensation: Check liquid level in both catchpots during operation.
Avoid overflowing of the catchpots. Install a level sensor (order-no. 699908) for
monitoring if necessary (VACUUBRAND controller CVC 3000 or VNC 2 is required).
NOTICE
Do not allow the catchpots to get overfilled. Maximum liquid level approx. 80% to
avoid problems when removing the catchpots.
Check liquid level in both catchpots regularly and drain catchpots in time.
Permissible range of coolant temperature at the exhaust waste vapour condenser:
-15°C to +20°C
Check hose connections prior to starting operation of the cooling system.
Check coolant hoses regularly during operation.

Replacing diaphragms and valves
All bearings are encapsulated and are filled with long-life lubricant. Under normal
operating conditions, the pump is maintenance free. 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. Check every capacitor regularly by measuring its capacity
and estimating its operation time. Exchange old capacitors early enough to prevent
a failure. The capacitors have to be replaced by an electrician. Depending on individual cases it may be efficient to check and clean the pump heads on a regular
basis. In case of normal wear the lifetime of the diaphragms and valves is > 10000
operating hours.
- Prevent internal condensation, transfer of liquids or dust. The diaphragm and
valves will be damaged, if liquids are pumped in significant amount.
If the pump is exposed to corrosive media or in case of deposits, maintenance should
be carried out frequently.
- Regular maintenance will improve the lifetime of the pump and also protect both
man and environment.
Ensure that maintenance is done only by suitable trained and supervised technicians.
☞ Ensure that the pump cannot be operated accidentally. Never operate the pump
if covers or other parts of the pump are disassembled. Never operate a defective or damaged pump.
☞ Before starting maintenance isolate the pump from the electrical supply and
wait two minutes after isolating the equipment from mains to allow the capacitors to discharge. Avoid the release of pollutants. Allow sufficient cooling of the
pump before starting maintenance.
• Attention: The pump might be contaminated with the process chemicals that have
been pumped during operation. Ensure that the pump is decontaminated before
maintenance and take adequate precautions to protect people from the effects
of dangerous substances if contamination has occurred. Ensure that the maintenance technician is familiar with the safety procedures which relate to the products processed by the pumping system.
• Wear appropriate safety-clothing when you come into contact with contaminated
components. Avoid the release of pollutants.
NOTICE
Before starting maintenance vent the pump and isolate it from the vacuum system
and the electrical supply. Drain condensate if applicable, avoid the release of pollutants. Allow sufficient cooling of the pump. Separate pump from cooling water circuit
(MD 1C + AK + EK).
