29.2 520R and 520R2 tube loading

520R continuous tubing pumpheads are factory-set to accept Watson-Marlow 1.6mm-wall tubing. 520R2 continuous tubing pumpheads are factory set to accept Watson-Marlow 2.4mm-wall tubing. Pumping performance may be adversely affect- ed if Watson-Marlow tubing is not used.

￿Mark a 225mm (8 7⁄8 in) length onto the section of the tubing which is to be located into the pumphead. Caution: Placing more than 225mm (8 7⁄8 in) of tube inside the pumphead may result in reduced tube life.

￿Open the lower spring-loaded tube clamp and locate the tubing, with the first 225mm (8 7⁄8 in) length mark aligned to the inside face of the spring-loaded part of the tube clamp. Release the clamp.

￿Disengage the rotor clutch by fully depressing the yellow clutch button on the side of the rotor hub and turning the hub a few degrees while the clutch button is still depressed. The rotor can now rotate independently of the gearbox and motor for one full revolution. If the clutch re-engages before tube fitting is complete, depress the clutch button again and turn the rotor a few degrees.

￿Feed the tubing around the pumphead track, turning the rotor as necessary. Make sure the tubing is not twisted or pinched between the guide rollers and the track. Ensure that the second 225mm (8 7⁄8 in) mark is adjacent to the inner edge of the upper tube clamp.

￿Open the upper spring-loaded tube clamp and locate the tubing into it, making sure there is no residual twist in the tubing, and that the tube sits centrally between the tube guide rollers. Release the clamp.
