31 Replacing the Membrane Label without removing the Control PCB
Assembly
If the LCD sub-assembly is
NOT
being replaced, then carry out the following procedure to replace the
membrane label. The hoseset assemblies can remain connected to the pump.
31.1 Separate the top case assembly from the front case assembly (refer to SER0009, Chapter 5,
“Pump Repair”, Page 13, Section 14):
Note: Do NOT remove the hoseset assemblies or control PCB assembly from the top case
assembly.
Note: Turn the top case assembly over so that the control PCB assembly is on top.
Note: Remove the membrane cable from the membrane connector on the control PCB assembly
(refer to Figure 55).
Note: Turn the top case assembly over so that the membrane label is on top.
Note: Remove the self-adhesive membrane label (Fig 56, 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.
31.2 Inspect the surface of the top case from where the membrane label was removed. Carefully
remove any adhesive residue.
31.3 Remove the backing paper from the new self-adhesive membrane label (Fig 56, Item 10).
31.4 Make sure the orientation of the membrane label is correct, and then do the following:
31.4.1 Pass the end of the membrane cable through the slot in the top case assembly and
then towards the rear edge of the top case assembly (refer to Figure 56).
31.4.2 Carefully guide the end of the membrane cable so that it passes through the cutout in
the control PCB assembly (refer to Figure 55).
Note: Do not bend or crease the membrane cable.
31.5 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.
31.6 Turn the top case assembly over so that the control PCB assembly is on top.
31.7 Carefully push the end of the membrane cable into the membrane connector on the control PCB
assembly.
Note: Less than 2mm of the membrane cable can be inserted into the connector.
31.8 Install the top case assembly onto the front case assembly (refer to SER0009, Chapter 5, “Pump
Repair”, Page 14, Section 15).
