Replace the Pump Drives (Binary and High Speed Pumps)
Remove the Pump Head Assembly
3
Carefully lift out the pump drive assembly by holding it at the
pump drive and lifting it out of the front cover and bottom foam
part. Do not pull at the pump encoder or otherwise apply force
to it.
4
Insert the new pump drive assembly such that it aligns with
the module housing. Do not confuse the left and the right
assembly. The figure shows the horizontal alignment of bolts
for connection to the pump heads.
5
Connect the pump drive to the power cables. Looking from the
front of the module, pump drives are numbered 1 to 4 from left
to right (in figure bottom to top). Cables are labeled and need
to be connected accordingly.
6
Connect the pump drive encoders to the encoder cable tree.
Make sure the connectors are pushed in completely.
