Watson-Marlow 701S/R - Manual (Page 8)

Tube loading
1. If the pump is running, stop it by turning the forward/off/reverse switch to
its central position. The track acts as a guard to the rotor, and should not
be removed until the pump has been stopped.
2. Turn the track compression spring knobs anti-clockwise about six turns.
This raises the springs and aids both track removal and replacement.
3. Release the track by unscrewing the track securing bolt on the left hand
side of the pumphead and withdrawing the bolt fully. Lift the track by its
handle and slide out the right hand side of the track from under the
springs.
4. Release in turn the two tube clamps by pulling on the release levers on
either side of the front plate of the pumphead, and lift out both clamps.
5. Lay the tubing across the pumphead and secure the suction side by
sliding in the first tube clamp (with its lip pointing outwards) and pressing it
down firmly. Loosely fit the second tube clamp.
6. Slip the right hand end of the track under the springs and position the left
hand end so that the track securing bolt can be inserted.
7. Tighten the track securing bolt with the Allen key provided to prevent
removal by hand. The Allen key size is 6mm. Spare Allen keys are
available from Watson-Marlow Limited or its distributors.
When the track has been fitted, screw down both the spring adjuster nuts
fully.
