1.1 Scope of this manual
This manual provides installation, operation and
maintenance instructions for the BOC Edwards
XDS35i Scroll pump. You must use your pump as
specified in this manual. Read this manual before you
attempt to install and operate your pump.
Important safety information is highlighted as
WARNING and CAUTION instructions; you must
obey these instructions. The use of WARNINGS
and CAUTIONS is defined below.
WARNING
Warnings are given where failure to
observe the instruction could result
in injury or death to people.
CAUTION
Cautions are given where failure to observe the
instruction could result in damage to the
equipment, associated equipment and process.
The units used throughout this manual conform to
the SI international system of units of measurement.
Pressures are stated as absolute pressures
throughout this manual.
Warning - hot surfaces.
1.2 Description
The XDS35i pump 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 XDS pump may be used for some
pumping applications involving corrosive substances
and particulates; for information on pumping
flammable gases, please refer to Section 4.5 and
contact BOC Edwards for any further assistance.
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.

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, refer to Figure 1,
item 8) must be set to the correct position in
accordance with the power supply being used, refer
to Section 3.5.2.
The XDS35i is designed to run from atmospheric
pressure however, if the inlet pressure exceeds
100 mbar for an extended period, the inverter may
reduce the motor speed. The pump will speed up
again after the pressure is reduced.

The pump is air-cooled by a fan (3) mounted at the
opposite end to the motor. The fan will run on for
one minute after the pump is switched off. The
XDS35i incorporates a thermal protection device
that will stop the motor in the event of thermal
overload e.g. high ambient temperature. The pump
will restart after it has cooled down.
The pump is mounted on rubber feet (6).
The pump is fitted with an hours counter (11), which
indicates the total time that the pump has run.

1.3 Gas ballast control
XDS Dry Pump
To pump high vapour loads, gas ballast can be
delivered into the pump to prevent condensation of
the vapour carried by the pumped gases.
Air can be introduced to the low vacuum stages
through the gas ballast control (2). Alternatively, an
inert gas such as nitrogen can be supplied through a
suitable external valve and by using the appropriate
adaptor, available as an accessory, refer to
Section 7.3.3.
The gas ballast control has three positions:
• Closed (position '0')
• Low flow (position 'I')
• High flow (position 'II')
1.4 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.

3.1 Safety
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
The BOC Edwards XDS35i pump is
not recommended for pumping
explosive gases or hazardous
substances.
You must ensure that the XDS35i pump is suitable
for your application. If you have any doubt about the
suitability of the XDS35i pump for your application,
refer to the BOC 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).
• Loose slings should not be used to lift the
XDS35i.
WARNING
Take care when moving the pump
into position. The pump's weight
makes it difficult to slide and
movement should be attempted
using two people.
• Wear the appropriate safety clothing when
you come into contact with contaminated
components. Dismantle and clean
contaminated components inside a fume
cupboard.
• Vent and purge your vacuum system before
you start installation work.
• Ensure that the installation technician is
familiar with the safety procedures that relate
to the products handled by the pumping
system.
• Disconnect the other components in the
pumping system from the electrical supply so
that they cannot be operated accidentally.

INSTALLATION
WARNING
Prevent any part of the human body
coming into contact with the vacuum.
A suitably trained and supervised technician must
perform the installation of the XDS35i pump. 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.
WARNING
Use suitable lifting equipment
to move the XDS35i pump.
The mass of the pump is
approximately 48 kg.
• Mechanical lifting equipment should be
attached to the lifting eye on the pump.
3.2 System design considerations
Consider the following points when you design your
pumping system:
Use a suitable valve to isolate the pump from your
vacuum system if you need to allow the pump to
warm up before pumping condensable vapours or if
you need to maintain vacuum when the pump is
switched off.
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.
If you use the pump in a high ambient temperature
and have a high gas throughput, the temperature of
the pump body may approach 70 ºC and you must
fit suitable guards to prevent contact with hot
surfaces.

Make sure that the exhaust pipeline cannot become
blocked. If you have an exhaust isolation valve, make
sure that you cannot operate the pump with the
valve closed.
Provide for a purge of inert gas when you shut down
the pumping system, to dilute dangerous gases to
safe concentrations.
3.3 Unpack and inspect
WARNING
Use suitable lifting equipment
to move the XDS35i pump.
The mass of the pump is
approximately 48 kg.
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.
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.
3.5 Electrical installation
3.5.1 Check and configure the pump
CAUTION
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 8) 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
If pumping for a prolonged period
above 100 mbar inlet pressure, use
an exhaust silencer (refer to
CAUTION
Section 7.3.2) or connect to an
appropriate exhaust line.
If using an overload circuit breaker it must be of a
time lag type because of 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.
Make the electrical connections to the pump motor
with an IEC60320 cable socket (C19) that satisfies
your local electrical standards.
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.
Take note of the following information when you
connect the pump to your vacuum system.
• To minimise noise and exhaust emissions, it is
recommended that the pump is connected to
an exhaust line or a silencer (refer to
Section 7.3.2).
• For optimum pumping speeds, ensure that the
pipeline connected to the pump inlet is as
short as possible and has a suitable internal
diameter.
• Support the vacuum pipeline to prevent
loading of the coupling joints.
Issue A Nov 02

XDS Dry Pump
• If necessary, incorporate flexible bellows in
your system pipelines to reduce the
transmission of vibration and to prevent
loading of the coupling joints. If you use
flexible bellows, you must ensure that you use
bellows that have a maximum pressure rating
which is greater than the highest pressure that
can be generated in your system. We
recommend that you use BOC Edwards
bellows.
• Incorporate an inlet isolation valve in the
pipeline from the vacuum system to the pump,
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.
• Ensure that the sealing surfaces are clean and
scratch-free.
PAGE

INSTALLATION
We recommend that you use an exhaust extraction
system suitable for use with all of the process gases
you will pump. Ensure that the exhaust extraction
system cannot become blocked or obstructed when
the pump is operating.
A small amount of tip seal wear product may collect
in the exhaust duct of the pump. The dust may be
blown out with the initial burst of air after the pump
has been vented. This is quite common and the
amount of dust seen will reduce over time.
3.7 Leak test the system
After you have installed the XDS pump, leak test the
system and seal any leaks found.

4.1 Use of gas ballast control
You can use the gas ballast control to optimise the
performance of the scroll pump for your application.
The performance characteristics of the pump with
the different ballast settings are shown in
Section 2.2.2. You can change the position of the gas
ballast control when the pump is off or when the
pump is operating.
4.1.1 Gas ballast control
Use the gas ballast control to change the amount of
air introduced into the final stage of the pump. Use
of gas ballast will reduce the condensation of
vapours in the pump; the condensates would
contaminate the pump. You can turn the gas ballast
control to select one of the three positions, as
follows:
4.2 Start up procedure
WARNING
Ensure that your system design does
not allow the exhaust pipeline to
become blocked.
CAUTION
A fine black dust may be emitted from the exhaust
of the scroll pump during start up, particularly
when the pump is new or if new tip seals are fitted.
Refer to Section 5.6 for further information when
fitting new tip seals.
Use the procedure below to start up the pump:
1. Ensure that any vacuum system isolation valve is
closed (if fitted).
2. Connect a suitable lead from the power supply
to the electrical socket at the side of the pump.
PAGE
15
OPERATION
To select no gas ballast, turn the control position to
'0'. Use this setting:
• to achieve ultimate vacuum
• to pump dry gases.
To select low flow gas ballast, turn the control to
position 'I'. Use this setting:
• to pump low concentrations of condensable
vapours
• to decontaminate the pump.
To select high flow gas ballast, turn the control to
position 'II'. Use this setting:
• to pump high concentrations of condensable
vapours
• to clear excess vapours after processing.
3. Switch on the electrical supply to the pump,
using the on / off switch on the motor.
4. Always use the on / off switch to start / stop the
pump.
5. Open the vacuum system isolation valve (if
fitted).
4.3 To achieve ultimate vacuum
In order to achieve the best possible vacuum, the
pump should be operated with the gas ballast
control on position '0'. However, if the pump, or
elements of the vacuum system it is attached to, are
new or have been newly fitted, some atmospheric
moisture may be present. If atmospheric moisture is
present, run the pump with the gas ballast control in
position 'I' or 'II' for 20 minutes before switching to
position '0'. If moisture is allowed to remain, the
performance of the pump will be impaired.

Select a suitable gas ballast setting (gas ballast control
in position 'I' or 'II') when there is a high proportion
of condensable vapours in the process gases. This
OPERATION
will assist the vapours to pass through the pump
without condensing and keep the pump performance
from degrading.
4.5 To pump flammable gases
The XDS35i pump must not be used in an area
where flammable gases, vapours or dust are present
or could be present.
When using the XDS pump for pumping flammable
gases and/or vapours the pump mechanism must be
considered to be a source of ignition.
The following actions must be taken to ensure that
the gas being pumped stays out of the flammable
WARNING
Do not use the XDS pump for
pumping flammable gases, gas
mixtures or vapours that are within
their flammable range.
CAUTION
range.
• Ensure the system is leak tight.
• Dilute any flammable gases or vapours by
using an inert gas purge (e.g. N
) to the pump
2
inlet and/or gas ballast (accessory available) to
reduce their concentration in the pump and
exhaust line to less than one quarter of their
published lower explosive limits (lel).
• Prevent the condensation of flammable
vapours within the pump mechanism and
exhaust line by using an inert gas purge to the
pump gas ballast connection.
• The inert gas purge should be switched on to
remove air from the pump and exhaust before
the process starts. The purge flow can be
switched off at the end of the process only
after any remaining flammable gases or
vapours have been purged from the pump and
exhaust line.
• If liquids that produce flammable vapours
could be present in the pump foreline then the
inert gas purge to the XDS pump 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. The
inert gas purge flow rate should be continually
measured and if the flow rate falls below that
required, then the flow of flammable gases or
vapours to the pump must be stopped.

4. Carefully remove the fixed scroll assembly using
a lever in the slots provided to ease it from the
motor body as shown in Figure 8.
5. Gently move the fixed scroll assembly aside so
that the fan connector can be accessed. This is
fitted at the underside of the fan cowl and must
be undone in order to remove the fixed scroll
completely.
WARNING
Do not place fingers between the
scroll and the pump housing as they
could be injured if the motor is
rotated.

WARNING
Do not inhale the tip seal dust.
Do not blow the tip seal dust from

6. Place the fixed scroll assembly on a flat surface
so that the scroll is facing upwards.
7. Remove the tip seals. Dispose of all waste
materials in accordance with the instructions
given in Section 6.2. If the pump has been used
for anything other than clean applications, go to
step 8; if not move straight on to step 10.
8. Loosen the three screws that secure the fixed
scroll into the fan cowl. Remove the gas ballast
control knob and spring. Remove the exhaust
flange. Disconnect the wires going to the
thermal snap switch.
9. Place the scroll downwards taking care not to
damage the tops of the tip seal walls. Remove
the exhaust valve cap and lift out the exhaust
spring and valve, if they have not come out
when removing the valve cap. Replace the
spring and valve pad.
10. Make sure there is no debris visible on the
inside of the scrolls, especially in the tip seal
slot. Wipe with a soft, dry, lint free cloth to
remove any dust etc. Avoid excessive abrasive
cleaning to maintain the PTFE layer that was
deposited by the tip seal on the scrolls during
previous running. This will minimise the dust
generation and running in period on re-starting
the pump.

sections and the orbiting scroll tip seal must be
cut into 3 sections. Each scroll tip seal groove
has indicator marks to show where the tip seal
must be cut (refer to Figure 10).The seals have
a sealing face and the opposite face has minute
grooves. Ensure that the grooved side of the
seal is fitted downwards into the scroll, so that
the sealing face is upwards. Start at the centre
of the orbiting scroll and fit the seal into the
groove (refer to Figure 9). The seal should be as
close to the end of the groove as possible.
When the indicator mark is reached, cut the
seal to the mark. This allows an area into which
the seal can expand. Repeat for all sections in
both scrolls. Ensure that the tip seal is pushed
fully home, particularly at the pinch-points, with
finger pressure before reassembly.
12. Reassemble, making sure that the tip seals do
not fall out. Reconnect the fan connector, then
refit the fixed scroll assembly taking care to
tighten the six fixing screws progressively and
evenly.
13. Some period of running-in may be required
before optimum performance is reached.
Depending on the application, the vacuum
achieved directly following a tip seal
replacement may be sufficient for your
requirements. Typically, this can be up to a
decade more than the final vacuum achievable
with a bedded in tip seal. During run in, deposits
of tip seal dust will be produced. Ensure the
exhaust is connected to a silencer or an exhaust
line to collect tip seal deposit, refer to
Section 7.3.2 for further information. If
possible, occasional venting through the gas
ballast control or valve on the inlet is
recommended.
5.7 Test the motor condition
CAUTION
Do not flash test the XDS35i or damage to the
inverter may result.
Test the earth continuity and the insulation
resistance of the pump motor, in accordance with
local regulations for the periodic testing of electrical
equipment.
We recommend that the earth continuity is less
than 0.1
than 2M
If the pump fails these tests, you must contact BOC

5.8.2 The pump has failed to achieve the
specified performance
• Allow 1 hour from cold for the pump to warm
up to full operating temperature. If the pump
does not achieve the performance specified in
Section 2, make sure that this is not because
of your system design before you contact
your supplier or BOC Edwards for advice. In
particular, the vapour pressure of all materials
used in your vacuum system must be lower
than the specified ultimate vacuum of the
pump. Refer to Section 5.8 for a list of
possible causes for failure to achieve the
specified performance.
• If the electrical supply voltage is more than
10% below the lowest voltage specified on the
voltage indicator, the pump may operate
yielding a degraded vacuum performance.
