►Take particular care and pay special attention when transporting products manually.
►Do not stack the products.
►Wear protective equipment, e.g. safety shoes.
Safety
10/52

Risks during installation
DANGER
Danger to life from electric shock
Power supply packs that are not specified or are not approved will lead to severe injury to death.
►Make sure that the power supply pack meets the requirements for double isolation between
mains input voltage and output voltage, in accordance with IEC 61010 and IEC 60950.
►Make sure that the power supply pack meets the requirements in accordance with IEC 61010
and IEC 60950.
►Where possible, use original power supply packs or only power supply packs that correspond
with the applicable safety regulations.
DANGER
Danger to life from electric shock
When establishing the voltages that exceed the specified safety extra-low voltage (according to IEC
60449 and VDE 0100), the insulating measures will be destroyed. There is a danger to life from elec-
tric shock at the communication interfaces.
►Connect only suitable devices to the bus system.
WARNING
Risk of injury due to incorrect installation
Dangerous situations may arise from unsafe or incorrect installation.
►Do not carry out your own conversions or modifications on the unit.
►Ensure the integration into an Emergency Off safety circuit.
WARNING
Danger of death from poisoning due to toxic gases being expelled without an exhaust line
Exhaust gases and vapors are released from the turbo pumping station unhindered during normal us-
age. In the case of processes with toxic media, there is a risk of injury and danger of death due to
poisoning.
►Note the corresponding regulations for handling toxic substances.
►Toxic process gases should be safely conveyed away via an exhaust line.
CAUTION
Danger of injury from bursting as a result of high pressure in the exhaust line
Faulty or inadequate exhaust pipes lead to dangerous situations, e.g. increased exhaust pressure.
There is a danger of bursting. Injuries caused by flying fragments, the escaping of high pressure, and
damage to the unit cannot be excluded.
►Route the exhaust line without shut-off units.
►Observe the permissible pressures and pressure differentials for the product.
►Check the function of the exhaust line on a regular basis.
Risks during operation
WARNING
Danger of poisoning due to toxic process media escaping from the exhaust pipe
During operation with no exhaust line, the vacuum pump allows exhaust gases and vapors to escape
freely into the air. There is a risk of injury and fatality due to poisoning in processes with toxic process
media.
►Observe the pertinent regulations for handling toxic process media.
►Safely purge toxic process media via an exhaust line.
►Use appropriate filter equipment to separate toxic process media.
Safety
11/52

CAUTION
Danger of burns on hot surfaces
Depending on the operating and ambient conditions, the surface temperature of the vacuum pump
can increase to above 70 °C.
►Provide suitable touch protection.
Risks during maintenance, decommissioning and in event of malfunctions
WARNING
Health hazard through poisoning from toxic contaminated components or devices
Toxic process media result in contamination of devices or parts of them. During maintenance work,
there is a risk to health from contact with these poisonous substances. Illegal disposal of toxic sub-
stances causes environmental damage.
►Take suitable safety precautions and prevent health hazards or environmental pollution by toxic
process media.
►Decontaminate affected parts before carrying out maintenance work.
►Wear protective equipment.
CAUTION
Danger of burns on hot surfaces
In the event of a fault, the surface temperature of the vacuum pump can increase to above 70 °C.
►Allow the vacuum pump to cool down before carrying out any work.
►Wear personal protective equipment if necessary.
2.3 Safety precautions
DANGER
Danger to life from electric shock
Power supply packs that are not specified or are not approved will lead to severe injury to death.
►Make sure that the power supply pack meets the requirements for double isolation between
mains input voltage and output voltage, in accordance with IEC 61010 and IEC 60950.
►Make sure that the power supply pack meets the requirements in accordance with IEC 61010
and IEC 60950.
►Where possible, use original power supply packs or only power supply packs that correspond
with the applicable safety regulations.

3 Product description
3.1 Function
Diaphragm pumps are dry compressing positive displacement pumps. The movement of diaphragms
generates a periodic change of the suction chamber volume. The gas flow causes the valves to open
and close automatically. The pump unit is directly connected to the drive motor.

5 Installation
5.1 Installing the vacuum pump
Procedure
►Place the vacuum pump on a flat, horizontal surface.
►For stationary installation, screw the vacuum pump direct to the mounting surface.
►When installing the pump in a closed housing, ensure adequate air circulation.
►Keep the specifications on the motor rating plate visible and freely accessible.
5.2 Connecting the vacuum side
NOTICE
Property damage from contaminated gases
Pumping down gases that contain impurities (condensate, particles) damages the vacuum pump.
►Use suitable filters or separators from the Pfeiffer Vacuum range of accessories, to protect the
vacuum pump.
Installation and operation of accessories
Pfeiffer Vacuum offers a series of special, compatible accessories for its diaphragm pumps.
●Information and ordering options for approved accessories can be found online.
●Described accessories are not included in the shipment.
Preventing throttling losses
Using the shortest possible vacuum connection lines with large nominal diameter prevents
pressure losses.
Condensate separator
Pfeiffer Vacuum recommends the installation of a condensate separator in case vapors are
formed from moisture during evacuation.
Procedure
1. Remove the blind plug from the vacuum connection.
2. Establish the shortest possible connection between vacuum pump and vacuum chamber.
3. Choose a minimum vacuum line diameter equal to the nominal diameter of the vacuum connec-
tion.
4. Depending on the pump type, use PVC or metallic hoses with flange connections from the Pfeiff-
er Vacuum component shop.
5. Connect the vacuum pump to the vacuum system using the vacuum connection.
5.3 Connecting the exhaust side
WARNING
Danger of death from poisoning due to toxic gases being expelled without an exhaust line
Exhaust gases and vapors are released from the turbo pumping station unhindered during normal us-
age. In the case of processes with toxic media, there is a risk of injury and danger of death due to
poisoning.
►Note the corresponding regulations for handling toxic substances.
►Toxic process gases should be safely conveyed away via an exhaust line.
Installation

CAUTION
Danger of injury from bursting as a result of high pressure in the exhaust line
Faulty or inadequate exhaust pipes lead to dangerous situations, e.g. increased exhaust pressure.
There is a danger of bursting. Injuries caused by flying fragments, the escaping of high pressure, and
damage to the unit cannot be excluded.
►Route the exhaust line without shut-off units.
►Observe the permissible pressures and pressure differentials for the product.
►Check the function of the exhaust line on a regular basis.
Condensate separator
Pfeiffer Vacuum recommends installing a condensate separator, with condensate drain at
the lowest point of the exhaust line.
Procedure
1. Check the installed silencer for free passage.
2. Choose a minimum exhaust line diameter equal to the nominal diameter of the connection flange.
3. Depending on the pump type, use PVC or metallic hoses with flange connections from the Pfeiff-
er Vacuum component shop.
4. Option: In case of higher gas throughputs, mount an exhaust line.
5. Route the piping downwards from the vacuum pump, to prevent condensate return.
6. Support or suspend the piping to the vacuum pump so that no piping system forces act on the
vacuum pump.
5.4 Establishing the electric connection
WARNING
Risk of injury due to incorrect installation
Dangerous situations may arise from unsafe or incorrect installation.
►Do not carry out your own conversions or modifications on the unit.
►Ensure the integration into an Emergency Off safety circuit.
5.4.1 Grounding the vacuum pump
Fig. 3: Connect grounding cable
