Introduction
1.2 ATEX directive implication
This equipment is designed to meet the requirements of Group II Category 3 equipment in accordance with Directive
94/9/EC of the European Parliament and the Council of 23rd March 1994 on the approximation of the laws of the
Member States concerning equipment and protective systems intended for use in potentially explosive atmospheres.
(The ATEX Directive).
The ATEX Category 3 applies in respect of potential ignition sources internal to the equipment. An ATEX Category has
not been assigned in respect of potential ignition sources on the outside of the equipment as the equipment has not
been designed for use where there is an external potentially explosive atmosphere.
There is no potential source of ignition within the pump during normal operation but there may be potential sources
of ignition under conditions of foreseeable and rare malfunction as defined in the Directive. Accordingly, although
the pump is designed to pump flammable materials and mixtures, operating procedures should ensure that under all
normal and reasonably foreseeable conditions, these materials and mixtures are not within explosive limits.
When flammable materials are present within the equipment you must:
zNot allow air to enter the equipment.
zEnsure the system is leak tight.
Further details can be obtained by contacting Edwards UK on [phone].

Figure 1 - XDS100B scroll booster
1.3 Description
The XDS100B Scroll Booster is shown in Figure 1. Refer to Figure 1 for item numbers in brackets in the following
descriptions.
The XDS pump is a compact, reliable vacuum pump which is suitable for use on vapour handling processes. The
XDS100B is a scroll booster, with a pumping mechanism designed specifically for high pumping speed. It cannot
exhaust directly to atmosphere, and must be backed by a primary pump; it is intended for use in conjuction with
Edwards XDS35i or XDS46i scroll pumps.
The body of the pump includes a fixed scroll and an orbiting scroll. The orbiting scroll is controlled by the electric
motor through an eccentric cam on the motor drive shaft. The movement of the orbiting scroll, meshed with the
fixed scroll, forms successive crescent shaped volumes in the pump. Gas that enters the pump through the inlet is
compressed by the movement of the orbiting scroll and swept towards the centre of the fixed scroll. The compressed
gas enters the exhaust port near the centre of the stationary scroll and is exhausted from the pump through the
outlet, which must be connected to a primary pump.
The XDS is a truly dry vacuum pump, as all the bearings, with their hydrocarbon lubricant, are isolated from the
vacuum space.
The pump mechanism is driven directly by a three phase electric motor. The motor is controlled by an inverter,
which manages the supply of current to the motor in accordance with operating conditions, and allows the pump
to be connected to a single phase supply. The voltage changeover switch, beneath the voltage changeover switch
cover, (7) must be set to the correct position in accordance with the power supply being used, refer to Section 3.5.2.

Introduction
The XDS100B is a scroll booster, optimised for maximum pumping speed at inlet pressures between 1 mbar and
10 mbar (refer to Figure 2). The XDS100B is not suitable for prolonged operation at inlet pressures above 20 mbar,
for pumpdown of large volumes, or for rapid cyclic duty. Such operation may cause the pump to become hot or the
inverter to reduce the motor speed. The pump will speed up again after the load is reduced.
The pump is air-cooled by a fan (2) mounted at the opposite end to the motor. The fan will run on for one minute
after the pump is switched off. The XDS100B incorporates a thermal protection device that will stop the motor in the
event of thermal overload, such as high ambient temperature. The pump will restart after it has cooled down.
The pump is fitted with an hours counter (10), which indicates the total time that the pump has run.
1.4 Gas ballast control
The XDS100B booster does not have a gas ballast option; condensation is not likely to occur in the pump, as the normal
operating pressure is too low.
1.5 Construction
The pump scrolls are made of anodised aluminium. The motor housing is aluminium. All surfaces of the pump which
are exposed to the pumped gases are free from copper, zinc and cadmium.
Other materials of construction include fluorocarbon elastomer, nitrile, chemically resistant polymers, nickel and
stainless steel.
The tip seal is a PTFE composite material.

3 Installation
3.1 Safety
You must ensure that the XDS100B booster is suitable for your application. If you have any doubt about the suitability
of the XDS100B booster for your application, refer to the Edwards guidelines on vacuum pump and vacuum system
safety (see associated publications at the end of the contents list at the front of this manual).
A suitably trained and supervised technician must perform the installation of the XDS100B Booster. Obey the safety
instructions listed below when you install the XDS pump, especially when you connect the pump into an existing
system. Details of the specific safety precautions are given at the appropriate point in the instructions.
zWear the appropriate safety clothing when you come into contact with contaminated components. Dismantle
and clean contaminated components inside a fume cupboard.
zVent and purge your vacuum system before you start installation work.
zEnsure that the installation technician is familiar with the safety procedures that relate to the products
handled by the pumping system.
zDisconnect the other components in the pumping system from the electrical supply so that they cannot be
operated accidentally.
3.2 System design considerations
Consider the following points when you design your pumping system:
Avoid high levels of heat input into the pump from the process gases, otherwise the pump may overheat, and cause
the thermal overload device to open.
Make sure that the foreline from the booster to the backing pump and the exhaust pipeline from the backing pump
outlet cannot become blocked. If you have an exhaust isolation valve, make sure that you cannot operate the pump
with the valve closed. Refer to Section 3.6.
Provide for a purge of inert gas when you shut down the pumping system, to dilute dangerous gases to safe
concentrations.
WARNING
Obey the safety instructions given below and take note of appropriate precautions. If you do not,
you can cause injury to people and damage to equipment.
WARNING
Prevent any part of the human body coming into contact with the vacuum.
WARNING
The Edwards XDS100B booster is not recommended for pumping explosive gases or hazardous
substances.

Installation
A732-01-880 Issue A
3.3 Unpack and inspect
Remove all packing materials, remove the pump from its packing box, remove the protective covers from the inlet
and outlet ports and inspect the pump. If the pump is damaged, notify your supplier and the carrier in writing; state
the item number of the pump together with your order number and your supplier's invoice number. Retain all the
packing materials for inspection. Do not use the pump if it is damaged. If the pump is not to be used immediately,
replace the protective covers. Store the pump in suitable conditions, as described in Section 6.1. Refer to Section 6.2
for disposal of materials.
3.4 Locate the pump
Provide a firm, level platform for the pump. Locate the pump so that the Run/Standby switch is accessible.
If your pump will be located inside an enclosure, make sure that there is adequate ventilation at both ends of the
pump, so that the ambient temperature around the pump does not exceed 40 ºC. There must be a minimum space
of 25 mm between the pump and the enclosure walls.
3.4.1 Mechanical fixing
Note: If you wish to secure the pump you may do so using the four holes located on each corner of the pump base,
we recommend you use M8 bolts.
3.5 Electrical installation
3.5.1 Check and configure the pump
CAUTION
Before changing the voltage, unplug the power supply. Ensure that the pump is correctly configured for your
electrical supply otherwise you may cause damage.
Ensure that the voltage shown on the voltage indicator (refer to Figure 1, item 7) on the motor cover corresponds
with your electrical supply voltage. If it does not, you must change the configuration of the pump motor to match
your supply voltage; use the procedure below.
1. Undo the two screws and lift off the voltage indicator moulding.
2. Rotate the voltage indicator moulding so that the correct voltage is uppermost.
3. Replace the two screws.
WARNING
Use suitable lifting equipment to move the XDS100B booster. The mass of the pump is 48 kg.
zMechanical lifting equipment should be attached to the lifting eye; loose slings should not
be used.
zTake care when moving the pump into position. Its weight makes it difficult to slide.
Movement should be attempted using two people.
WARNING
If the pump is to be used on the floor of a work area, position the power lead and the exhaust and
inlet hoses with care. Ensure that personnel in the area are aware of any obstructions around the
pump.

Installation
3.5.2 Connect the pump to your electrical supply
Make the electrical connections to the pump motor with an IEC60320 cable socket (C19) that satisfies your local
electrical standards. To ensure CSA/UL compliance a suitable approved mains supply cord must be used; refer to
Table 10 for parts available from Edwards.
For recommended fuse ratings, refer to Table 7 in Section 2.4.
CAUTION
If using an overload circuit breaker it must be of a time lag type because of the high start up current.
CAUTION
If using an earth leakage device e.g. an RCD, use at least a 30 mA rated unit to avoid trip during start up.
The pump will automatically restart after restoration of the power supply following power failure.
3.6 Inlet and outlet connections
CAUTION
The XDS100B cannot exhaust directly to atmosphere and must be backed by a suitable primary pump.
Refer to Figure 1. Before you connect the pump to your vacuum system, remove the plastic cap from the inlet and
the exhaust, and ensure that the inlet strainer is fitted to the pump inlet port. Use appropriate NW40 vacuum fittings
for connection to your system.
WARNING
Ensure that the electrical installation of the XDS pump conforms with your local and national safety
requirements. It must be connected to a suitably fused and protected electrical supply with a
suitable earth point.
WARNING
If pumping dangerous gases or vapours, connect the exhaust of the backing pump to a suitable
treatment plant to prevent the discharge of dangerous gases and vapours to the surrounding
atmosphere.
WARNING
If the booster or backing pump is operated with the foreline or backing pump exhaust line blocked,
high pressures may be generated in the pipework.

Installation
A732-01-880 Issue A
Take note of the following information when you connect the pump to your vacuum system.
zTo minimise noise and exhaust emissions, it is recommended that the primary pump backing the XDS100B is
connected to an exhaust line or a silencer (refer to Section 7.3.2).
zFor optimum pumping speeds, ensure that the pipeline connected to the pump inlet is as short as possible
and has a suitable internal diameter. Also ensure a suitable backing pump is used, such as the XDS35i or
XDS46i, and the connection between booster and backing pump is as short as possible with a suitable internal
diameter.
zSupport the vacuum pipeline to prevent loading of the coupling joints. If necessary, incorporate flexible
bellows in your system pipelines to reduce the transmission of vibration and to prevent loading of the
coupling joints.
zIf the booster and its backing pump are operated with the exhaust line blocked, a pressure of 5.5 bar(a) may
be generated in the exhaust pipework. Foreline pressure may reach 1.45 bar(a). Connect the pump using
appropriate pipework and fittings.
zIncorporate an inlet isolation valve in the pipeline from the vacuum system to the booster pump and to the
primary pump. These will enable the vacuum system, so that you can isolate the vacuum system from the
pump when it is switched off and prevent the suckback of process gases and debris into the vacuum system.
zEnsure that the sealing surfaces are clean and scratch-free.
We recommend that you use an exhaust extraction system suitable for usewith all of the processgases you willpump.
Ensure that the exhaust extraction system cannot become blocked or obstructed when the pump is operating.
3.7 Leak test the system
After you have installed the XDS pump, leak test the system and seal any leaks found.
