15 520RC, 520R2C and 520REC rotor settings

520RC, 520R2C and 520REC pumpheads are factory-set to give optimum tube life with
Watson-Marlow tubing. Radial roller positions should not be adjusted in any circumstances
as this will adversely affect pumphead performance and invalidate warranty. Tamper-proof
rotor arm occlusion setting screws are fitted to warn operators from occlusion adjustment.
Tubing with a wall thickness other than 1.6mm or 2.4mm can be used only with a
pumphead set up for that purpose during manufacture. Contact Watson-Marlow technical
support.

Note: 520RC, 520R2C, and 520REC pumpheads can not be adapted to use tube with walls
thicker than 2.4mm.
