Notes: The Item Numbers listed above are for bareshaft pumps without motors. However, this manual contains

general information on pump motors. For detailed information on the specific motor fitted to the pump,

refer to the Motor Instruction Manual (P600-74-000) supplied with the pump.

The CDX/IDX Pumping System Instruction Manual (P600-74-600) supplied with the system will define the

build specification of the pump; that is, the type of motor and any accessories fitted.

If the CDX pump is part of an ATEX system, an ATEX system instruction manual (P600-74-500) will be

supplied, which defines the installation, operation and maintenance requirements for ATEX compliance.

Do not expose any part of the body to vacuum. If so, there will be danger of injury. The procedures in the following sections assume that there is a pump inlet isolation valve fitted to the pump. © Edwards Limited 2013. All rights reserved. Page 43 Edwards and the Edwards logo are trademarks of Edwards Limited.
Page 50: Atex System Control
In the first 30 seconds of pumpdown, open the inlet isolation valve slowly if there is liquid in the inlet pipeline, in order to minimize the ingress of liquid (entrained in the process gas stream) into the pump.

Page 51: Shut Down The Pump
CAUTION If the pump is operating in an ambient temperature between -20 and -5 °C (-4 and 23 °F), Edwards recommends that the pump is never shut down, other than for maintenance. If doubts about this, contact Edwards for advice.

260 °C (500 °F) and above. These breakdown products are very dangerous. The pump may have overheated if it was misused, if it malfunctioned, or if it was in a fire. Edwards Safety Data Sheets for the fluorinated materials used in the pump are available on request: contact the supplier or Edwards.
Page 54: Check The Oil Levels
Adjust the maintenance plan for IDX and non-ATEX pumps according to experience. When maintaining the pump, use Edwards maintenance and service kits. These contain all of the seals and other components necessary to complete maintenance operations successfully. The Item Numbers of these kits are given Section 7.3.
