2. Introducon
2.1 Scope of this manual
This manual provides installaon, operaon and maintenance instrucons for the
XDS35i, XDS35iC, XDS35iE, and XDS35iCE scroll pumps. The pump must be used as
specied in this manual. Read this manual before installing and operang the pump.
2.2 ATEX direcve implicaon
This equipment is designed to meet the requirements of Group II Category 3 equipment
in accordance with Direcve 2014/34/EU of the European Parliament and the Council of
29th March 2014 on the approximaon of the laws of the Member States concerning
equipment and protecve systems intended for use in potenally explosive
atmospheres. (The ATEX Direcve)
The ATEX Category 3 applies in respect of potenal ignion sources internal to the
equipment. An ATEX Category has not been assigned in respect of potenal ignion
sources on the outside of the equipment as the equipment has not been designed for
use where there is an external potenally explosive atmosphere.
There is no potenal source of ignion within the pump during normal operaon but
there may be potenal sources of ignion under condions of foreseeable and rare
malfuncon as dened in the Direcve. Accordingly, although the pump is designed to
pump ammable materials and mixtures, operang procedures should ensure that
under all normal and reasonably foreseeable condions, these materials and mixtures
are not within explosive limits. Category 3 is considered appropriate for the avoidance of
ignion in the case of a rare malfuncon which allows ammable materials or mixtures
to pass through the pump whilst within their explosive limits.

2.3 Descripon
Refer to Figure: General view for item numbers in brackets in the following descripons.
The XDS pump is a compact, reliable vacuum pump which is suitable for use on vapour
handling processes. It may be used for some pumping applicaons involving corrosive
substances and parculates, for informaon on pumping ammable gases, please refer
to Implicaon of ATEX direcve on page 24 and contact us for any further assistance.
The body of the pump includes a xed scroll and an orbing scroll. The orbing scroll is
controlled by the electric motor through an eccentric cam on the motor drive sha. The
movement of the orbing scroll, meshed with the xed scroll, forms successive crescent
shaped volumes in the pump. Gas that enters the pump through the inlet is compressed
by the movement of the orbing scroll and swept towards the centre of the xed scroll.
The compressed gas enters the exhaust port near the centre of the staonary scroll and
is exhausted from the pump through the outlet.
The XDS is a dry vacuum pump, as all the bearings, with their hydrocarbon lubricant, are
isolated from the vacuum space.

A73001880_P - Introducon

The pump has an NW40 (item 1) inlet and inlet strainer.
The pump mechanism is driven directly by a three‑phase electric motor. The motor is
controlled by a drive, which manages the supply of current to the motor in accordance
with operang condions and allows the pump to be connected to a single phase
supply. The voltage changeover switch beneath the voltage changeover switch cover
(item 8) must be set to the correct posion in accordance with the power supply being
used, refer to Connect the pump to the electrical supply on page 21.
The pump 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 aer the pressure is reduced. Maximum rated connuous
operang pressure at 40 °C ambient is 40 mbar.
The enhanced pump versions (XDS35iE and 35iCE) are equipped with patented
technology which prevents over‑compression within the scroll mechanism at high
operaonal pressure and large throughput applicaons. Twin by‑pass valves release
suciently compressed gas directly to the pump exhaust, increasing pump eciency,
lowering power consumpon and enhancing pumping speed. Valve operaon occurs at
inlet pressures greater than 300 mbar, meaning the pump is tailored towards
applicaons which dwell at higher pressure. The eliminaon of over‑compression at high
operaonal pressure, reduces power consumpon and diminishes bearing loads,
extending bearing life. Consequently, the enhanced versions are capable of operaon
without limitaons to both the size of vacuum chamber, or the frequency of pump down
on cyclic dues.
Note:
The pump modicaons within the enhanced version have a small adverse eect on the
ulmate vacuum achieved however, the pump has a larger tolerance to operang
altude and ambient temperature.
The pump is air‑cooled by a fan (item 3) mounted at the opposite end to the motor. The
fan will connue to run for one minute aer the pump is switched o. The pump
incorporates a thermal protecon device that will stop the motor in the event of thermal
overload, for example, high ambient temperature. The pump will restart aer cooling
down.
2.4 Gas ballast control
To pump high vapour loads, gas ballast can be delivered into the pump to prevent
condensaon of the vapour carried by the pumped gases.
Air can be introduced to the low vacuum stages through the gas ballast control (item 2)
(not ed on the No Gas Ballast variant). Alternavely, 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 Gas ballast adaptor on page 35.
The gas ballast control has three posions:
▪ Closed (posion '0')
▪ Low ow (posion 'I')
▪ High ow (posion 'II')

4. Installaon
4.1 Safety
WARNING:
Obey the safety instrucons in this secon and take note of appropriate precauons.
Failure to observe these instrucons may result in injury to people and damage to
equipment.
WARNING:
Do not expose any part of the human body to vacuum as it can cause injury.
WARNING:
The pump is not recommended for pumping explosive gases or hazardous
substances.
WARNING:
Use suitable liing equipment to move the pump. The mass is approximately 48 kg.
WARNING:
Take care when moving the pump into posion. The pump's weight makes it dicult
to slide and movement should only be aempted by two people.
▪ A suitably trained and supervised technician must install the pump.
▪ Ensure that the installaon technician is familiar with the safety procedures that
relate to the products processed by the pump.
▪ Wear the appropriate safety clothing when coming into contact with contaminated
components.
▪ Dismantle and clean contaminated components inside a fume cupboard.
▪ Vent and purge the vacuum system before starng installaon work.
▪ Disconnect other components in the pump from the electrical supply so that they
cannot be operated accidentally.
▪ Refer to the Vacuum Pump and Vacuum System Safety manual (publicaon
number P40040100) before installing and using the pump to process hazardous or
ammable materials.
▪ Safely route any electrical cables and pipes to prevent a trip hazard.
▪ Check all required components are available and are of the correct type before
starng work.
▪ Do not reuse O‑rings or seals.
05/2022 - ©Edwards Limited
Page 17A73001880_P
A73001880_P - Installaon

▪ Leak test the system aer installaon is complete and seal any leaks found to
prevent leakage of hazardous substances out of the system and leakage of air into
the system.
▪ Mechanical liing equipment should be aached to the liing eye on the pump.
▪ Loose slings should not be used to li the pump.
4.2 System design consideraons
WARNING:
Ensure the exhaust pipeline cannot become blocked. If an exhaust isolaon valve is
ed, ensure the pump cannot be operated with the valve closed.
Consider the following points when designing the pumping system:
We recommend the use of a foreline vacuum isolaon valve to allow the pump to warm
up before pumping condensible vapours or if the vacuum needs to be maintained when
the pump is not running.
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 the pump is used in a high ambient temperature with high gas throughput, the pump
body temperature may approach 65 °C. We recommend the use of addional guarding
to prevent contact with hot surfaces under these condions.
Dilute ammable mixtures to safe concentraons by providing an inert gas diluon
purge. Contact our applicaons team for further advice on diluon requirements if
required.

4.3 Unpack and inspect
WARNING:
Use suitable liing equipment to move the pump. Mechanical equipment should be
aached to the liing eyes, loose slings should not be used. Failure to do so can
cause injury to people and damage to the equipment. Refer to Table: General
mechanical data for the mass of the pump.
Remove all packing materials, remove the pump from its packing box, remove the
protecve covers from the inlet and outlet ports and inspect the pump.
If the pump is damaged, nofy the supplier and carrier in wring within three days, state
the Item Number of the pump together with the order number and supplier's invoice
number. Retain all packing materials for inspecon. Do not use the pump if it is
damaged.
If the pump is not to be used immediately, replace the protecve covers. Store the pump
in suitable condions, as described in Storage on page 34. Refer to Disposal on page 34
for disposal of materials.
4.4 Locate the pump
WARNING:
Route and secure cables, hoses and pipework during installaon to avoid possible
risk of trips.
CAUTION:
If the pump will be located inside an enclosure, ensure there is adequate venlaon
at both ends of the pump, so that the ambient temperature of the pump does not
exceed 40 °C. A minimum space of 25 mm between the pump and the enclosure walls
is required.
Provide a rm, level plaorm for the pump. Locate the pump so that the gas ballast
control (if ed) and the Run/Standby switch is accessible.
4.4.1 Mechanical xing
CAUTION:
Use the four holes located on each corner of the pump base to secure the pump, if
required. We recommend you to use of M8 bolts.
