Manual-02:PB0439/2
Fundamental work with regard to lifting, transportation, installation, starting-up, maintenance and repair should be performed by qualified personnel only. The unit must be isolated from mains power while work is being carried out. The motor mus t be secured against accidental start-up.
There is a user-replaceable type fuse in the fuse holder above the power input connector at the back of the pump . In some countries, the mains power plug contains an additional replaceable fuse.
There are no user-serviceable fuses or parts inside this pump.
This pump must be used only for its intended purpose.
The pump must be accessible at all times to facilitate operation and maintenance. Access points must not be obstructed or blocked. Do not fit any devices to the drive unit other than those tested and approved by Watson-Marlow Ltd. Doing so could lead to injury to persons or damage to property for which no liability can be accepted.
The pump's main plug is the disconnecting device (for isolating the motor drive from the mains supply in an emergency). Do not position the pump so that it is difficult to disconnect the mains plug.
If hazardous fluids are to be pumped, safety procedures specific to the particular fluid and application must be put in place to protect against injury to persons.
This product does not comply with the ATEX directive and must not be used in explosive atmospheres.
The PF7 contains a non- replaceable Manganese Dioxide Lithium Battery (Li/MnO2), IEC CR2032, with a typical capacity of 225mAh, containing 0.07g of Lithium.
Primary operator protection from rotating parts of this pump is provided by isolating the pump from mains power before opening the pump head tube bridge. The pump also provides a tube bridge open indicator. If the tube bridge is opened, the tube bridge open screen is displayed.
The tube bridge must be closed for the warning screen to clear and the pump to start.

4 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.
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, the seal also advances. After the roller has passed, the tube returns to its original shape, creating a partial vacuum which is filled by fluid drawn from the inlet port.
Before the roller reaches the end of the track, a second roller compresses the tube at the start of the track, isolating a packet of fluid between the compression points. As the first roller leaves the track, the second continues to advance, expelling the packet of fluid through the pump’s discharge port. At the same time, a new partial vacuum is created behind the second roller into which more fluid is drawn from the inlet port.
Backflow and siphoning do not occur, and the pump effectively seals the tube when it is inactive. No valves are needed.
The principle may be demonstrated by squeezing a soft tube between thumb and finger and sliding it along: fluid is expelled from one end of the tube while more is drawn in at the other.
Animal digestive tracts function in a similar way.
Suitable applications
Peristaltic pumping is ideal for most fluids, including viscous, shear- sensitive, corrosive and abrasive fluids, and those containing suspended solids. They are especially useful for pumping operations where hygiene is important.
Peristaltic pumps operate on the positive displacement principle. They are particularly suitable for metering, dosing and dispensing applications. Pumps are easy to install, simple to operate and inexpensive to maintain.
5 When you unpack your pump
