Danger of damage to the seals and danger of the pump bursting.
Install the line without shut-off valves on the exhaust side.
Pumpe nicht mit Überdruck am Einlass betreiben; max. zulässige Drücke und Druck-
differenzen beachten.
Assemble silencer at the diaphragm head 2;
– alternatively connect exhaust line.
Choose the cross-section of the exhaust line to be at least the size of the nominal
connection diameter of the vacuum pump's exhaust connection.
8
CAUTION
Lay piping from the pump sloping downward so that no condensate can flow
back into the pump; otherwise fit a condensate separator.
– If an air trap is created in the system, then a device for draining condensation
water must be provided at the lowest point.
Emission of toxic substances from the exhaust!
Danger of poisoning from emitted gases or vapours, which can be detrimental to health
and/or can pollute the environment, depending on the particular application.
Comply with the applicable regulations when working with toxic substances.
Only officially approved filter systems may be used to separate and remove these
substances.
5.4 Connecting to the mains power supply
The pump is driven by single-phase extended voltage range motors with reversible voltage ranges.
Excess voltage!
Danger of destroying the motor.
Power connections must comply with local regulations. Voltage and frequency infor-
mation given on the motor rating plate must correspond to the mains voltage and
frequency values.

Voltage ranges: 90-127 V, 50/60 Hz, 187-259 V, 50/60 Hz
Motor protection
A self-locking thermal winding protector switches off the pump motor in the event
of overheating (> 95°C).
Allow the pump to cool off several minutes.
– Pump runs-up automatically after cooling off.
10
6 Operation
6.1 Before switching on the pump
Compare the voltage information on the rating plate with the mains voltage.
Check that the exhaust connection allows free flow (max. permissible pressure
1.1 bar absolute).
– Activate the shut-off valves in such a way that they open before or at the same
time as the pump is started.
Protect the pump sufficiently from taking in contaminants by means of suitable
precautions (e.g. dust filters).
Dangerous overpressure overload!
Mixing up the connections leads to a dangerous overpressure overload in the pump,
and the motor could be damaged.
Before commissioning, it is imperative that you ensure that the pressure does rise
above the maximum permissible pressure on the pressure side.
Start pumps at a maximum pressure differential of 1 bar between inlet and outlet.
Operation
CAUTION
6.2 Switching on the pump
The pump can be switched on in any pressure range between atmospheric and
ultimate pressure.
No special precautions are necessary when pumping dry gases. In order to attain
the lowest possible final pressures, the gas ballast valve should be closed.
The pump attains the stated values for throughput rates and final pressure levels
only once the operating temperature is reached (after approximately 15 minutes).
Switch on the pump with the vacuum flange closed and allow to warm up for 15
minutes.
Hot surface!
Danger of burns if hot parts are touched. Depending on the operating and ambient
conditions, the surface temperature of the pump may rise above 70 °C.
In this case, use suitable finger guards.
Intermittend operation with TC via relay
box (accessory)
To prolong the life of diaphragm pumps, intermittent operations can be selected
with lesser gas throughputs of < 0.18 mbar l/s. This means that, dependent on the
TMP power take-up, the backing pump will be switched on and off. TMP power
take-up is dependent on the fore-vacuum pressure and gas throughput.
– By comparing the power take-up with an upper and a lower limit value, the rel-
ative switch-on duration with lesser gas throughputs can be reduced to approx.
1 to 60%.
– To avoid too frequent switching on, the buffer volume in the fore-vacuum line
should amount to ≥0.5 liter from approx. 0.018 mbar l/s.
CAUTION
11
Operation
6.3 Pumping condensable vapours
Should the process gases contain condensable gases present at high percentages,
the vacuum pump must be operated with a gas ballast (i.e. with an open gas ballast
valve).
Reactive, explosive or otherwise dangerous mixtures!
Uncontrolled gas inlet at the gas ballast valve can result in dangerous mixtures.
By implementing the required safety measures, the user must prevent potentially ex-
plosive mixtures from occurring in the inside of the pump and from being ignited in
the event of a diaphragm crack by mechanically produced sparks, hot surfaces or
static electricity.
If necessary, use inert gas for ventilation and gas ballast supply.
Bad final vacuum and damage to the pump!
Danger of condensation and a reduced final vacuum during operation without a gas ballast or in case of insufficient supply of flushing gas.
Only pump vapors when the pump is warm and the gas ballast valve is open.
When the process has been completed, allow the pump to continue running for
about 30 minutes at atmospheric pressure with the gas ballast open.
WARN ING
NOTE
Gas ballast valve Letting in gas ballast improves the discharge of condensate, and the pump
achieves the specified final vacuum more quickly.
The lower part of the valve casing has been constructed in such a way to permit the
mounting of a magnetic valve with a connection thread of G 1/8".

7 Maintenance
7.1 Precautions
Pump parts may be contaminated from pumped media!
Danger of poisoning due to contact with harmful substances.
Decontaminate the pump before carrying out any maintenance work.
In the event of contamination, take suitable safety precautions to prevent your health
The valves and the diaphragms are wear parts. If the rated ultimate vacuum is no
longer achieved, the pump interior, the diaphragms and the valves must be
cleaned and the diaphragms and valves must be checked for cracks or other damage.
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.
Turn off the vacuum pump, vent to atmospheric pressure and allow to cool, if

pumps are contaminated or the declaration on contamination is missing, Pfeiffer
Vacuum performs decontamination at the shipper's expense.
Neutralise the pump by flushing it with nitrogen or dry air.
Close all openings airtight.
