Storage This product has an extended shelf life. However, care should be taken after storage to ensure that all parts function correctly. Users should be aware that the pump con- tains a battery with an unused life of seven years. Long-term storage is not recom- mended for peristaltic pump tubing. Please observe the storage recommendations and use-by dates which apply to tubing you may wish to bring into service after storage. 5 Information for returning pumps Equipment which has been contaminat

6 Peristaltic pumps - an overview Peristaltic pumps are the simplest possible pump, with no valves, seals or glands to clog or corrode. The fluid contacts only the bore of a tube, eliminating the risk of the pump contaminating the fluid, or the fluid contaminating the pump. Peristaltic pumps can operate dry without risk. How they work A compressible tube is squeezed between a roller and a track on an arc of a circle, creating a seal at the point of contact. As the roller advances along the tube,

7 Safety notes In the interests of safety, this pump and the tubing selected should only be used by competent, suitably trained personnel after they have read and understood this manual, and considered any hazard involved. If the pump is used in a manner not specified by Watson-Marlow Ltd, the protection provided by the pump may be impaired. Any person who is involved in the installation or maintenance of this equipment should be fully competent to carry out the work. In the UK this person shoul

There are moving parts inside the pumphead. Before opening the tool- unlockable pumphead guard, ensure that the following safety directions are fol- lowed. 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. Ensure that protective clothing and eye protection are worn if hazardous fluids are pumped.

9 Good pump installation practice 9.1 General recommendations A correctly engineered installation will promote long tube life. Site the pump on a flat, horizontal, rigid surface, free from excessive vibration, to ensure correct lubri- cation of the gearbox. Allow a free flow of air around the pump to ensure that heat can be dissipated. Ensure that the ambient temperature around the pump does not exceed 40C. The STOP key on the keypad will always stop the pump. However, it is recommend- ed that a

Do not strap the control and mains power cables together. Do keep delivery and suction tubes as short and direct as possible - though ideally not shorter than 1m - and follow the straightest route. Use bends of large radius: at least four times the tubing diameter. Ensure that connecting pipework and fittings are suitably rated to handle the predicted pipeline pressure. Avoid pipe reducers and lengths of smaller bore tubing than the pumphead section, particularly in pipelines on the suction side

10 Connecting this product to a power supply The voltage selector is mounted in the switchplate at the rear of the pump, protected from water by the 520N module. The module must be removed to allow access to the switchplate. See 22.1 520N module fit- ting. Set the voltage selector to 115V for 100-120V 50/60Hz supplies or 230V for 200-240V 50/60Hz supplies. Always check the voltage selector switch before connecting the mains supply. Make suitable connection to an earthed single-phase mains elect

If the mains power cable is inappropriate for your installation, it can be changed. This operation can be carried out with the 520N module in place, or after it has been removed, as shown here for clarity. Ensure that the pump is isolated from the mains power. Remove the six screws from the interface card cover underneath the pump. Lift off the interface card cover. You may find it convenient to remove the cover completely; if so, remove the cover earth lead. Undo the terminal block connec
