Ensure that the pump is isolated from the mains power.
Ensure that there is no pressure in the pipeline.
If a tube failure has occurred, ensure that any fluid in the pumphead has been
allowed to drain to a suitable vessel, container or drain.
Protective clothing and eye protection must be worn if hazardous fluids are
pumped.
Primary operator protection from rotating parts of the pump is provided by the

4 Good pump installation practice
4.1 General recommendations
A correctly engineered installation will promote long tube life.
The pump may be set up so that the direction of rotor rotation is clockwise or counter-clockwise, whichever is convenient. Please note, however, that tube life will be
greater if the rotor rotates clockwise; and that performance against pressure will be
maximised if the rotor rotates counter-clockwise.
Peristaltic pumps are self-priming and self-sealing against backflow. No valves are
required in inlet or discharge lines, except as described below. Valves in the process
flow must be opened before the pump operates. Users are advised to fit a pressure
relief device between the pump and any valve on the discharge side of the pump to
protect against damage caused by accidental operation with the discharge valve
closed.
