INSTALLATION SAFETY
WARNING

PAGE

Obey the safety instructions given below and take the appropriate precautions. If you do not, you can cause injury to people and damage to
equipment.

INSTALLATION SAFETY

WARNING
The system should not be operated with the BOC Edwards panels removed.

Potential hazards on the dry pumping system include electricity, hot surfaces, process chemicals, Fomblin oil, nitrogen and water under pressure.
Detailed safety information is given in Section 3 and BOC Edwards Publication Number P300-20-000 'Vacuum Pump and Vacuum System Safety'.
• Only BOC Edwards engineers may install the dry pumping system. Users can be trained by BOC Edwards to conduct the tasks described in this manual,
contact your local service centre or BOC Edwards for more information.
• Do not remove the temporary cover or blanking plate from the dry pumping system inlet and exhaust until you are ready to connect the dry pumping
system to your vacuum or exhaust-extraction system. Do not operate the dry pumping system unless the inlet and exhaust are connected to your vacuum
and exhaust-extraction system.
• Vent and purge the process system (if the dry pumping system is to replace an existing pumping system) with nitrogen for 15 minutes before you start
installation work. Refer to Section 4.
• Disconnect the other components in the process system from the electrical supply so that they cannot be operated accidentally.
• Electrical, nitrogen and water supplies are all potentially hazardous energy sources. Before carrying out any maintenance the supply of these sources should
be locked and tagged out.
• Route and secure cables, hoses and pipework during installation to avoid possible trip hazards.
• The pump system includes provision for ventilation extraction and secondary containment of oil and water leaks. Any unintended overflows or spills must
be removed immediately to avoid risk of slips.
• Obey all national and local rules and safety regulations when you install the dry pumping system. Consult BOC Edwards Publication Number P300-20-000
(Vacuum Pump and Vacuum System Safety) before you pump hazardous materials. This publication is available on request: contact your supplier or BOC
Edwards.

2.1

Locate the dry pumping system
WARNING

PAGE

You must use suitable lifting equipment to move the system. It is too heavy to lift by hand.

Do not exceed the topple angle of 10 ° when moving the pump. Wheel the system on its castors to move it into its operating position. The system
should only be wheeled short distances over flat surfaces. If the floor surface is uneven or has obstacles the system should be lifted with suitable
lifting equipment.
2.3

Connect the dry pumping system to your vacuum/exhaust system and interstage connection (if fitted)
WARNING
Pipe the exhaust to a suitable treatment plant to prevent the discharge of dangerous gases or vapours to the surrounding atmosphere.

WARNING
Do not operate the system with the exhaust pipeline blocked. If the exhaust pipeline is blocked, the system can generate exhaust pipeline pressures
of up to 7 bar (7 x 105 Pa).

2.5

Connect the nitrogen supply (if provided)

2.5.1

Flammable/pyrophoric materials

PAGE

WARNING

You must obey the instructions and take note of any precautions given below to ensure that pumped gases do not enter their flammable ranges.

INSTALLATION SAFETY

When flammable or pyrophoric materials are present within the equipment you must:
• Not allow air to enter the equipment
• Ensure that the system is leak tight
• Ensure that pumped gases do not enter their flammable range. This can be achieved by diluting flammable gases/vapours or oxidisers in the pump by supplying
sufficient inert gas purge, for example dilution with nitrogen to below one quarter LEL (lower explosive limit) or, if that is not practical, to below 60% LOC
(limiting oxidant concentration).
• For further information please refer to Semiconductor Pumping Application Guide (Publication no. P411-00-090) or contact BOC Edwards: refer to the
address page at the rear of this manual for details of your nearest BOC Edwards company.
2.5.2

Gas purges
WARNING
If you use inert gas purges to dilute dangerous gases to a safe level, ensure that the pump is shut down if an inert gas supply fails.

Switch on the inert gas purge to remove air from the pump and the exhaust pipeline before the process starts. Switch off the purge flow at the end of the process
only after the remaining flammable gases or vapours have been purged from the exhaust pipeline.
If liquids that produce flammable vapours could be present in the pump foreline, then the inert gas purge to the dry pumping system should be left on all the time
this liquid is present. Flammable liquids could be present in the foreline as a result of condensation or may be carried over from the process.
When calculating the flow rate of inert gas required for dilution, consider the maximum flow rate for the flammable gases/vapours that could occur. For example,
if a mass flow controller is being used to supply flammable gases to the process, you should assume a flow rate for flammable gases that could arise if the mass
flow controller is fully open.
Continually measure the inert gas flow rate: if the flow rate falls below that required, then the flow of flammable gases or vapours to the pump must be stopped.

2.6

Leak-test the system
WARNING

PAGE

2.7

Connect the electrical supply to the dry pumping system
WARNING
This equipment is suitable for Installation Category II as defined in IEC 60664-3. Connect the system to the electrical supply through a suitably
rated isolator/connector for your dry pumping system.
WARNING
Ensure that the system and your electrical supply cable are suitably protected against earth (ground) faults and that the earth (ground) conductor
of the electrical supply cable is longer than the phase conductors in the connector. You must fit a second protective earth (ground) conductor
(with a cross-sectional area at least equal to phase conductor size) to the protective earth (ground) stud.
WARNING
All connections to the interface control must be double insulated or have equivalent protection. Do not connect voltages greater than
30 V a.c. or 60 V d.c. to the control/interface connections. If you do, the interface control will not provide protection against electric shock.

WARNING
There is no overload protection provided on the Systemable (T variant) system.

Jun 07

Issue A

INSTALLATION SAFETY

Leak test the system after installation and seal any leaks found to prevent leakage of dangerous substances out of the system and leakage of air
into the system.

2.10

Connect the cooling-water hoses
WARNING

PAGE

INSTALLATION SAFETY

Do not leave the cooling-water supply turned on until after you complete the electrical installation of the pump. If you do, condensation may form
inside the enclosure and there may be a risk of electric shock.
2.12

Commission the iGX system
WARNING
During some application cycles it is possible that the system may exceed OSHA 1910.95 Occupational Noise Exposure Limits, the EU noise
directive 2003/10/EC or other regional noise limits dependant upon the process, duty cycle, installation or environment in which being operated.
A sound pressure survey must be conducted after installation and, if necessary, controls implemented to ensure that the relevant limits are not
exceeded during operation and that adequate precautions are taken to prevent personnel from exposure to high noise levels during operation.

2.13

Install additional safety equipment
WARNING
If your Process Tool/control system needs to know the total flow rate of nitrogen to the system for safety reasons, install suitable measurement
equipment in the nitrogen supply pipeline.
WARNING
If you use the nitrogen purges to dilute dangerous gases to a safe level, ensure that the system shuts down if the nitrogen supply to the system fails.

4.1

Safety and maintenance frequency
WARNING
Electrical, nitrogen and water supplies are all potentially hazardous energy sources. Before carrying out any maintenance the supply of these
sources should be locked and tagged out.
WARNING
Personal protection equipment should be checked and used as specified by its supplier. Hazardous chemicals that have been pumped are located
within the pumps and piping. Use of suitable protective gloves and clothing along with a respirator is recommended if contact with substances is
anticipated.
Particular caution should be exercised when working with Fomblin oil which may have been exposed to temperatures greater than 260 °C. Refer
to BOC Edwards Material Safety Data Sheets for detailed information.
• Ensure that the maintenance technician is familiar with the safety procedures which relate to the products pumped.
• Allow the pumps to cool to a safe temperature before you fit lifting bolts or start maintenance work.
• Vent and purge the dry pumping system with nitrogen before you start any maintenance work.
• Isolate the dry pumping system and other components in the process system from the electrical supply so that they cannot be operated accidentally. Note
that the emergency stop switch on the dry pumping system is not an electrical isolator, unless a disconnect box accessory is installed.
• Wait for at least four minutes after you have switched off the electrical supply before you touch any electrical component on the dry pumping system.

Issue A

Jun 07

• Route and secure cables, hoses and pipelines during maintenance to avoid possible risk of trips or entrapment.
• Ensure that any oil or water collected in the secondary containment drip tray is removed before moving the system.
• The enclosure panels should only be removed with the use of a special tool, when the system has been switched off and allowed to cool sufficiently (as an
indication the system should be left for one hour with cooling water still connected at the flow rate specified in Table 1.

• Take care to protect the sealing-faces from damage.
• Do not touch or inhale the thermal breakdown products of fluorinated materials which may be present if the iGX system has been overheated to 260 °C
and above. These breakdown products are very dangerous. Fluorinated materials in the iGX system may include oils, greases and seals. The iGX system
may have overheated if it was misused, if it malfunctioned or if it was in a fire. BOC Edwards Material Safety Data Sheets for fluorinated materials used in
the pump are available on request: contact your supplier or BOC Edwards (refer to the address page at the rear of this manual for contact details).
4.2

Relocate the system for maintenance
WARNING
The substances that accumulate in the exhaust-pipe, elbow and check-valve (supplied separately) can be dangerous. Do not allow these substances
to come into contact with your skin or eyes. Do not inhale vapours from these substances. Fit blanking caps to the inlet and outlet flanges when
you move the exhaust-pipe, elbow or check-valve around your workplace.
The majority of synthetic oils/grease can cause inflammation of the skin (dermatitis). Safety precautions must be taken to prevent prolonged skin
contact with these substances. Use of suitable protective gloves and clothing along with a respirator is recommended if contact with the substance
is anticipated.
System process gases and residue can be highly toxic. Take all necessary precautions when handling components that have, or could have, come

iGX Dry Pumping System
1.3
PAGE

Priority of control

The iGX system can be controlled by a number of modules: the Pump Display Terminal (PDT), from the tool through the MicroTIM, or from the front panel local
control membrane (refer to Figure 4). Only one of these can have control of the iGX system at any one time. That is, once one of these has control of the iGX
system, control requests from the other are denied.

INTRODUCTION

The PDT indicates who is in control. LEDs are also provided on the rear panel, front panel or PDT, which illuminate to indicate 'in control'. Please refer to Figure 5.
1.4

Active utility control

Active Utility Control (AUC) is available on the iGX system. This function reduces the power of the iGX system while on stand-by. The power reduction is
achieved by reducing the rotational speed of the iGX pump. This function also reduces the nitrogen purge of M variant systems while in stand-by mode.
Advanced Active Utility Control (AAUC) is also available. This function, in addition to AUC, can reduce the water flow of the iGX system while on stand-by,
therefore allowing further reductions in power. Contact BOC Edwards for advice.
The AUC functionality is controlled by the on/off process signal from the Tool Interface Module.

iGX Dry Pumping System

INSTALLATION

2.1

Locate the iGX system

PAGE

Use suitable lifting equipment (refer to Figure 2) attached to the lifting eyebolt (15) to move the iGX system close to its final operating position.

Adjust the levelling feet (24) to make sure that the iGX system is level and is not supported by the castors. The lifting eyebolt must be retained for future
use with this system.

If required, the iGX system can be secured to the floor by fitting suitable bolts or studs (not supplied) through the M10 docking points on the chassis.
If vibration transmission to the floor is a concern, suitable vibration isolators (not supplied) should be fitted between the docking points and the bolt or stud,
if doing this the levelling feet will need to be removed.

4.
5.

If preferred, the lifting eyebolt can be removed and replaced with the lifting eyebolt hole plug supplied with the systems.
Ensure that access is possible to the emergency stop button (refer to Figure 4, item 1), if not use an iGX Disconnect Box (refer to Section 6.3).

Issue A

INSTALLATION

Use the following procedure to locate the iGX system in its operating position. The iGX system must be located on a firm, level surface, to ensure that the system
is not damaged.

Please refer to the appropriate Section in A546-00-860 for
important safety information when you see a warning symbol.

iGX Dry Pumping System
If you want to secure the iGX in place to prevent inadvertent movement (for example, during an earthquake), take note of the following:
• The iGX system seismic brackets (Figure 2, item 19) are designed to withstand a level 4 earthquake in a ground floor installation.
• The iGX system can be secured to the floor by fitting suitable bolts or studs (not supplied) through the 17.5 mm hole in the seismic brackets.
• If vibration transmission to the floor is a concern, suitable vibration isolators (not supplied) should be fitted between the seismic brackets and the bolt or
stud.
• Although the iGX system is supplied with four seismic brackets, two brackets are capable of protecting the system during an earthquake. The system can
therefore be secured as shown in Figure 6 for example, to reduce the effective system footprint if required.
• If all four seismic brackets are to be used, ensure that the bolt spacing is adequate for the floor strength and loads anticipated.

INSTALLATION

2.2

Lubrication

The iGX system is given a charge of oil before it leaves the factory. There is no requirement to check and adjust the oil level.
2.3

Connect the iGX system to your vacuum/exhaust system and interstage connection (if fitted)

Do not reuse any O-ring or O-ring assembly and do not allow debris to get into the iGX system during installation.
When you connect your iGX system to your vacuum system, take note of the following:
• To get the best pumping speed, ensure that the pipeline which connects the vacuum system to the iGX system is the minimum length possible and has an
internal diameter not less than the iGX system inlet-port.
• Ensure that all components in the vacuum pipeline have a maximum pressure rating which is greater than the highest pressure that can be generated in your
system.
• Incorporate flexible pipelines in the vacuum pipeline to reduce the transmission of vibration and to prevent loading of coupling-joints. We recommend that
you use BOC Edwards braided flexible pipelines. The pipelines should be suitable for 110 °C.
• Adequately support vacuum/exhaust pipelines to prevent the transmission of stress to pipeline coupling-joints.
• Incorporate a pressure gauge in the inlet pipeline, so that you determine that the iGX system operates correctly.
• You must be able to isolate the iGX system inlet from the atmosphere and from your vacuum system if you have pumped or produced corrosive chemicals.
• The outlet of the exhaust pipe can have a check-valve (optional accessory) fitted which prevents the suck-back of exhaust vapours after the iGX system is
shutdown. The check-valve also provides additional attenuation of the pulses in exhaust pressure.
