sories

Risk of improper

changes

Improper changes can have extensive consequences:

– dangerous electrical malfunctions can occur.

– mechanical malfunctions can occur and the safety of the unit can be affected.

Do not modify the unit.

General safety in-

structions

Do not expose any body parts to the vacuum.

Observe all safety and accident prevention regulations.

Regularly check the proper observance of all safety measures.

Always ensure a safe connection to the protective earthing conductor (PE, protection

class I).

Do not loosen any plug connection during operations.

Wait for the rotor to reach standstill before peforming work on the high vacuum flange.

Keep leads and cables well away from hot surfaces (> 70 °C).

Never fill or operate the calibration system with cleaning agent.

Do not operate the calibration system with open high vacuum flange.

Do not carry out any unauthorised modifications or conversions to the pumps.

The unit has been accredited with protection class IP 20. Take necessary measures

when installing into ambient conditions, which afford other protection classes.

Note the shipping instructions, when returning the unit.

Ensure the proper filling of the backing pump with operating fluid and lubricant.

Information requirements regarding possible risks

Every person, who does installation, operation or maintenance on the calibration sys-

tem, must read, understand and obey the safety relevant parts of these operating in-

structions.

The operator is obligated to indicate risks to every user, which come from the vacuum

pump, the pumped medium or the complete calibration system.

Installation and Operation of Accessories

Pfeiffer Vacuum pumps can be equipped with various adapted accessories. Installation,

operation and maintenance of connected devices are described in detail in the operat-

ing instructions of the single devices.

Refer to chapter "Accessories" for information about order numbers of components.

Only use original accessories.

Risk of contamination

WARNING

Contamination of the calibration system by contaminated devices

Contact with hazardous substances can cause health hazard.

Do not contaminate the calibration system by the use of contaminated devices.

In case of a contamination take appropriate safety measures to prevent health risks

from hazardous substances.

Decontaminate concerned parts before doing any maintenance.

WARNING

Danger of elektric shock

The calibration system is only de-energized with the power plug disconnected.

Switch off the master switch and disconnect the power plug before you do any work.

Prevent the unit from unintentional energizing and switching-on.

WARNING

Danger of electric shock

In case of defect, the parts connected to the mains supply are under voltage.

Always keep the mains connection freely accessible so that you can disconnect it at

any time.

WARNING

Danger due to lack of power disconnection device

Pump and electronic drive unit are not equipped with a power disconnection device. In-

stallation of a user-supplied power disconnection device in accordance with SEMI-S2.

Fit a circuit breaker with an interruption rating of min. 10,000 A.

WARNING

Danger of unsafe electrical installation

Safe operation after installation is the responsibility of the operator.

Do not independently modify or change the pump and electrical equipment.

Make sure that the system is integrated in an emergency off safety circuit.

Consult Pfeiffer Vacuum for special requirements.

NOTICE

Protect vacuum components against contamination

Dirt and damages affect the function of the calibration system.

Keep the calibration system and the gauges connected and in operation in order to

keep the calibration system clean and efficient.

Pay attention to cleanliness and damage protection when operating vacuum compo-

nents.

Ensure clean, greaseless and dry connection flanges.

Safety

Risk of incorrect han-

dling

Risk of overpressure

during venting

NOTICE

Risk of damage to the turbo pump because of contamination

No parts, particles or dusts may get into the calibration system.

Only remove blank flanges from the vacuum chamber for connection of vacuum

gauges!

NOTICE

Risk of damaging vavuum gauges

The calibration system or vacuum gauges can be damaged by incorrect handling during

the calibration process.

Obey the operating instructions of the vacuum gauges before the calibration.

NOTICE

Process stability due to constant rotation speed of the turbo pump

Inconstant rotation speed of the turbo pump can lead to negative influence on the cali-

bration process.

Make sure, that the rotation speed of the turbo pump remains stable throughout the

whole calibration process and does not decrease below the nominal value.

Obey the operating instructions of the display control unit DCU 110 regarding the

speed control of the turbo pump.

DANGER

Danger of excessive pressure in the vacuum chamber

For the connection of nitrogen or other pressurized gases to the vacuum chamber, ad-

ditional measures are necessary, to prevent a venting of the vacuum chamber to pres-

sures > 500 hPa (relative pressure).

Install a safety valve to the vacuum chamber.

Contact Pfeiffer Vacuum for selecting an appropriate safety valve.

NOTICE

Damage to vacuum gauges by venting

Some vacuum gauges must be switched off before venting them to atmospheric pres-

sure to prevent damage.

Obey the operating instructions of the used vacuum gauges.

NOTICE

Damage by excessive pressure in the vacuum chamber

Excessive pressure in the vacuum chamber can cause damage to connected compo-

nents and vacuum gauges.

Do not vent the vacuum chamber in excess of atmospheric pressure.

Connect a safety valve to the vacuum chamber.

2.2 Protective equipment

Determined situations concerning the handling of vacuum pumps require wearing of per-

sonal protective equipment. The owner, respectively the employer are obligated to pro-

vide an adequate equipment to any operating persons.

NOTICE

Risk of excessive inlet pressure at the turbo pump

The turbo pump can be damaged by a high rate of pressure rise during venting. When

the turbo pump is running, do the following:

Do not disconnect the vacuum gauges or blank flanges from the vacuum chamber.

Switch off the turbo pump and let it reach standstill (0 Hz).

Set the gas flow to the minimum on the gas dosing valve before you open the internal

shut-off valve.

Do not open the butterfly valve as long as the pressure in the vacuum chamber is

>1 hPa.

If you use pressurized venting gas, maintain the allowed rate of pressure rise, be-

cause the gas flow of the venting gas supply rises in accordance with the inlet pres-

sure.

Restart: Reduce the pressure in the calibration system with the backing pump to ≤

22 hPa.

NOTICE

Risk of overpressure in the calibration system with pressurized gas connection

The max. permitted pressure at the inlet of the gas dosing valve is 500 hPa (relative

pressure).

Install a safety valve on the vacuum chamber.

Use a pressure reducer.

Set the inlet pressure on the pressure reducer to < 500 hPa (relative pressure).

Close the gas dosing valve, when normal atmospheric pressure has been reached in

the vacuum chamber.

Avoid venting with pressure higher than normal atmospheric pressure.

Close the pressurized gas supply again after venting.

NOTICE

Correction factors for Pirani vacuum gauges

The applicable correction factors for Pirani vacuum gauges are given in the related op-

erating instructions, in order to convert the indicated equivalent nitrogen pressure into

the correct pressure for the measured gas.

Take and obey the correction factors given in the operating instructions of the vacuum

gauges.

DANGER

Danger to health by hazardous substances during maintenance or installation

Depending on the process vacuum pumps, components or operating fluids can be con-

taminated by toxic, reactive or radioactive substances.

Wear adequate protective equipment during maintenance and repairs or in case of

reinstallation.
