30 Replacing the Membrane Label by removing the Control PCB Ass'y from
the Top Case Ass'y
If the pump is being dis-assembled to replace the LCD sub-assembly, then carry out the following
procedure to replace the membrane label.
30.1 Remove the complete control PCB assembly from the top case assembly (refer to
Chapter 5, Page 29, Section 24).
30.2 Remove the Run button and button return spring from the top case assembly.
30.3 Turn the top case assembly over, so that the membrane label is on top.
30.4 Remove the self-adhesive membrane label (Fig 54, Item 10) from the top case assembly, and
withdraw the membrane cable out through the slot in the top case assembly.
Note: If you use a sharp tool to remove the membrane label, be careful not to scratch or
damage the surface of the top case.
Note: The old membrane label must be discarded because of the loss of adhesive and possible
damage to it during the removal process.
30.5 Inspect the surface of the top case from where the membrane label was removed. Carefully
remove any adhesive residue.
30.6 Remove the backing paper from the new self-adhesive membrane label (Fig 54, Item 10).
30.7 Make sure the orientation of the membrane label is correct and pass the end of the membrane
cable through the slot in the top case assembly (refer to Figure 54).
Note: Do not bend or crease the membrane cable.
30.8 Align the membrane label with the recess in the top case, and lower the membrane label onto
the top case. Press down firmly on the membrane label to secure it to the top case.
Note: Make sure the alignment is correct before you stick the membrane label to the top case.
If you have to remove the membrane label to re-align it, then the membrane label will
have to be discarded because of the loss of adhesive and possible damage to it.
30.9 Turn the top case assembly over, so that the membrane label is on the underside.
30.10 Put the Run button into the cutout in the top case, and put the button return spring over the
shaft of the Run button.
30.11 Install the complete control PCB assembly into the top case assembly (refer to
Chapter 5, Page 29, Section 25).
