620RE, 620RE4 and 620R Continuous tube loading
620R continuous tubing pumpheads are factory set to accept Watson-Marlow 600
series 3.2mm wall tubing. Pumping performance will be adversely affected if
Watson-Marlow tubing is not used.
Select the tube clamp set which is correct for the tubing size to be used.
Disengage rollers
Locate one end of the tubing into the lower port "U" clamp and hold firmly in
position.
Wrap the tubing tightly around the retracted rollers, making sure that there is no
twisting through its length.
Locate the other end of the tubing into the upper port "U" clamp.
Hold both ends of the tubing in one hand maintaining tension around the retracted
rollers.
Engage rollers
Close the guard and push it against the track until the latch engages
Ensure that continuous tubing is not loosely clamped at the pumphead ports.
Ensure that when the pump is re-started all of the rollers have re-engaged. A roller
which has not re-engaged will "click" continuously. No damage will occur if this
happens but the roller should be re-engaged manually using the 5mm Allen key.
Please refer to the Troubleshooting section.
