Removing the Power Supply PCB (Printed Circuit Board) Assembly

WARNING: DO NOT CONNECT THE MAINS/POWER CORDSET TO THE POWER
SUPPLY PCB ASSEMBLY, AND SWITCH ON THE MAINS/POWER SUPPLY,
WHEN THE REAR CASE IS REMOVED FROM THE PUMP. VOLTAGES IN
EXCESS OF 30 VOLTS RMS OR 50 VOLTS DC ARE PRESENT ON THE
POWER SUPPLY PCB ASSEMBLY AND CAN, IN CERTAIN
CIRCUMSTANCES, BE LETHAL.
CAUTION: Electrostatic discharge can seriously damage the power supply PCB
assembly. Adequate earthing/grounding precautions must be taken when
handling it.
Note: The power supply PCB assembly includes the battery pack connector, which is hard-wired to it.
26.1 Separate the top case assembly from the front case (Refer to Page 15, Section 14).
26.2 Remove the compressor assembly and mounting bracket from the pump (Refer to

screws (Fig 50, Item 20) to secure it.
27.2 If a new power supply PCB assembly is being installed, stick a new connector sealing strip
(Fig 50, Item 30) to the back of the battery pack connector. If the original power supply PCB
assembly is being re-installed, make sure the connector sealing strip is still stuck to the back of
the battery pack connector (Refer to Figure 50).
27.3 Make sure there is a second connector sealing strip stuck to the front case, adjacent to the
battery pack connector slot.
27.4 Insert the battery pack connector into the slot in the front case, and install the two screws
(Fig 50, Item 20) to secure it.
Note: Make sure the wires from the power supply PCB assembly to the battery pack connector
do not lie on top of the circular compressor support rubbers (Fig 50, Item 40).
27.5 Install the compressor assembly and mounting bracket into the pump (Refer to
Page 43, Section 37).
Install the top case assembly onto the front case (Refer to Page 16, Section 15).
