Removing the Control Printed Circuit Board (PCB) Assembly

CAUTION: Electrostatic discharge can seriously damage the control PCB assembly.
Adequate earthing/grounding precautions must be taken when handling it.
24.1 Remove the hose set assemblies (Refer to Page 9, Section 8).
24.2 Remove the motor and manifold assembly from the control PCB assembly (Refer to
Page 19, Section 18).
24.3 Carefully pull the membrane cable out of the membrane connector on the control PCB assembly
(Fig 48, PCB Con 10).
24.4 Remove the four screws (Fig 48, Item 30), and lift the control PCB assembly (Fig 48, Item 10)
out of the top case assembly (Fig 48, Item 20).
Note: Do not remove the four smaller screws (Fig 48, Item 40) which secure the LCD display to

Installing the Control Printed Circuit Board (PCB) Assembly

25.1 Put the top case assembly (Fig 48, Item 20) on a horizontal surface, with the inside surface
pointing upwards, and position the control PCB assembly (Fig 48, Item 10) just above it.
25.2 Carefully push the membrane cable into the membrane connector on the control PCB assembly
(Fig 48, PCB Con 10).
25.3 Make sure the Run button (Fig 48, Item 50) is installed into the cutout in the top case assembly,
and the button return spring (Fig 48, Item 60) is installed on the Run button.
25.4 Lower the control PCB assembly onto the four pillars in the top case assembly.
Note: Make sure the membrane cable is positioned in the cutout in the control PCB assembly.
Note: As the control PCB assembly is lowered onto the top case assembly, make sure the Run
switch on the control PCB assembly stays in the centre of the button return spring on the
top case assembly (Refer to Figure 49).
25.5 Install the four screws (Fig 48, Item 30) to secure the control PCB assembly.
25.6 Install the motor and manifold assembly onto the control PCB assembly, and back into the pump
(Refer to Page 25, Section 20).
25.7 Install the hose set assemblies (Refer to Page 10, Section 9).
