Changing the Pump Head
The pump head has been installed on drive before leaving the factory.
Please follow below procedure when changing a new pump head is
needed.
1. Loose the tightening screws which connecting the pump head and
the drive. Take down the pump head.
2.
Insert the flat end of the new pump head's shaft to the slot of
drive's coupling. Make the positioning hole of the pump head
match the positioning pin of the drive.
3.
Tighten the screws which connecting the pump head and the
drive. Try your best to tighten the screws in the same degree. Do
not over-tighten the screws to prevent the housing from
deforming. (Please reference the pump head operating manual for
details.)
Shut down the power supply before changing a new pump head.
Check the Pump Head Occlusion
Load the tubing in pump head and insert one side of tubing in
water and blow to the other side. There should be no air bubble in
water. If there is air bubble in water, that's because the wall
thickness of the tubing is too thin to be used in this pump head.
