Watson & Sons 520DUN user manual 29.3 520RE fitting the drain port

Page 85

￿The spring-loaded tube clamps must grip the tubing tightly enough to stop it moving in and out of the pumphead but must not over-squeeze the tube and throttle fluid flow. The tubing clamps are fitted with yellow sliders which can be clicked into two positions while the clamps are held open: the outer position will allow the clamps to grip the tube tightly; the inner will grip the tube loose- ly. Adjust the sliders to prevent tube movement during a few trial rotations of the rotor.

￿Close the guard, pushing it fully home until the latch engages.

￿Connect suitable pipework to the pumphead tubing using appropriate connec- tors.

￿Remember, when using Marprene or Bioprene tubing, re-tension the tubing after 30 minutes of running, as it may grow in length as it beds in. Re-tension so that 225mm (8 7⁄8 in) of tubing sits between the inside faces of the spring- loaded parts of the tube clamps.

29.3 520RE: fitting the drain port

The drain port is an optional extra, supplied with the pumphead. It is strongly rec- ommended that users fit it before the pump is operated. It may be done with the rotor in position or removed.

￿Remove the drain plug from the bottom of the pumphead. The drain plug is flexible. It may be removed using finger pressure from within the pumphead, or by accessing its flange from outside with a fingernail.

￿Drop the port into position from inside the pumphead.

￿Fit the supplied port retaining nut (3⁄8 in BSP) and finger-tighten.

￿Fit drainage pipework as required (not supplied).
