5.1 Safety information
The XDS100B pump is designed to require little user maintenance. Observe the following guidelines when carrying
out maintenance on the pump:

A suitably trained and supervised technician must maintain the pump.

Ensure that the maintenance technician is familiar with the safety procedures that relate to the products
processed by the pumping system.

Wear the appropriate safety clothing when coming into contact with contaminated components.

Dismantle and clean contaminated components inside a fume cupboard.

Do not reuse O-rings or seals.

Isolate the pump and other components from the electrical supply so that they cannot be operated
accidentally.

After maintenance has been completed, re-check the direction of pump rotation if the electrical supply has
been disconnected.

Check all required components are available and are of the correct type before starting work. Refer to
Section 7.3.5 .

Leak test the system after installation is complete and seal any leaks found to prevent leakage of hazardous
substances out of the system and leakage of air into the system.
WARNING

observe these instructions may result in injury to people and damage to equipment.
WARNING
Wait one minute for capacitor discharge after disconnecting the power supply before working on
the pump.
WARNING
The pump may be contaminated with the process chemicals that have been pumped during
operation. If so, ensure that the pump is decontaminated before maintenance and that adequate
precautions are taken to protect people from the effects of dangerous substances if contamination
has occurred.
WARNING
The XDS100B must be isolated from its backing pump before maintenance can begin. If the booster
backing pump is connected and operational the XDS100B scrolls will rotate.
