Cassette loading
The cassettes are designed only for use with manifold pump tubing. Place the
tube, without twisting or stretching it, into the tube retaining slots. Depress the
cam adjustment lever which will move the cassette leg inwards. Load the
cassettes into the pumphead starting at the drive end.
Ensure that both retaining lips are properly engaged, then raise the cam
adjustment lever to its vertical position to give the normal tube occlusion. The
final delivery pressure can be varied slightly by adjusting the cam lever
position.
Cassette removal
Depress the cam adjustment lever fully and lift out the cassette. There is no
need to switch off the drive to remove a cassette for tube changing.
The removal of a cassette will not disturb the pumping action of any other but
the pump must not be run for long periods of time without all the cassettes in
place.
For safety reasons, all cassettes should be in position in the pumphead during
normal running, even if some do not contain tubing.
Care and maintenance
When the pumphead needs cleaning, switch the drive off and isolate it from
the mains. Withdraw the cassettes from the pumphead and remove the
tubing. Wash the cassettes in water and mild detergent.
If fluid has been spilled into the pumphead, removal of the pumphead from
the drive will make cleaning easier. Periodically, inspect all moving parts for
wear and ensure all bearings and rollers are free to rotate.
