Page 10: Introduction
2.1 Scope of this manual This manual provides installation, operation and maintenance instructions for the XDS35i, XDS35iC, XDS35iE, and XDS35iCE scroll pumps. The pump must be used as specified in this manual. Read this manual before installing and operating the pump. -
Page 11: Description
The compressed gas enters the exhaust port near the centre of the stationary 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_N Page 9 11/2020 - ©Edwards Limited... -

4.6 Inlet and outlet connections WARNING: If pumping dangerous gases or vapours, connect the exhaust to a suitable treatment plant to prevent the discharge of dangerous gases and vapours to the surrounding atmosphere. A73001880_N Page 21 11/2020 - ©Edwards Limited... -
Page 24: Leak Test The System
This is quite common and the amount of dust seen will reduce over time. 4.7 Leak test the system Leak test the system and seal any leaks found after installing the pump. A73001880_N Page 22 11/2020 - ©Edwards Limited... -
Page 25: Operation
Use the procedure below to start up the pump: Ensure that any vacuum system isolation valve is closed (if fitted). Connect a suitable lead from the power supply to the appliance inlet at the side of the pump. A73001880_N Page 23 11/2020 - ©Edwards Limited... -
Page 26: To Achieve Ultimate Vacuum (If Gas Ballast Fitted)
If nitrogen purges are used to dilute dangerous gases to safe levels, ensure that the system shuts down if the nitrogen supply to the pump fails. The following actions must be taken to ensure that the gas being pumped stays out of the flammable range: A73001880_N Page 24 11/2020 - ©Edwards Limited... -
Page 27: Remote Operation Using 15-Way D Connector
Boost operation is not recommended for the pump as a permanent operation mode, as increased bearing loads will reduce the life of the pump bearings. Please consult us if the boost mode is intended to be used as the limits of operation are application dependent. A73001880_N Page 25 11/2020 - ©Edwards Limited... -

Page 34: Fault Finding
Following tip seal replacement, the pump has not been vented and a build-up of eroded tip seal dust is reducing running clearances. Refer to Replace the tip seals on page 30 for further information. A73001880_N Page 32 11/2020 - ©Edwards Limited... -
Page 35: The Pump Surface Temperature Is High
The connecting pipelines are too long. ▪ The inlet strainer is blocked. ▪ There is a leak in the system. ▪ The inverter is current limiting the supply. ▪ The pump is in idle mode. A73001880_N Page 33 11/2020 - ©Edwards Limited... -
Page 36: Storage And Disposal
Dispose the pump and any components removed from it safely in accordance with all local and national safety and environmental requirements. Take particular care with components and waste oil which have been contaminated with dangerous process substances. A73001880_N Page 34 11/2020 - ©Edwards Limited... -
