Separating the Top Case Assembly from the Front Case

CAUTION: Do NOT remove the hose set assemblies from the pump (Refer to
Page 9, Section 8) unless the top case assembly or the control PCB
assembly is being replaced (the motor and manifold assembly can be
replaced without removing the hose set assemblies). The elbow retaining
covers on the hose set assemblies are not designed to be removed from the
pump more than a couple of times. If the hose set assemblies are removed
unnecessarily, the screw cover hinges on them may split, and then the
complete hose set assemblies will have to be replaced.
When the rear case has been removed from the pump, the top case assembly (Fig 40, Item 20) is held
in position on the front case (Fig 40, Item 10) by three spigots on the front case which locate in the
corresponding holes in the top case assembly.
There are also two connections between the top case assembly and the front case:
• A ribbon cable connection from the control PCB assembly (in the top case assembly) to the power
supply PCB assembly (in the front case).
• A large diameter tube (Fig 40, Item 40) from the motor and manifold assembly (in the top case
assembly) to the compressor assembly (in the front case).
14.1 Remove the hose set assemblies from the pump (Refer to Page 9, Section 8), but ONLY if the
top case assembly or the control PCB assembly is being replaced (the motor and manifold
assembly can be replaced without removing the hose set assemblies). Otherwise, the top case
assembly can be separated from the front case with the hose set assemblies installed on the
pump.
14.2 Remove the handle and hook assembly, and the rear case, from the pump (Refer to
Page 13, Section 12).
14.3 Carefully lift the top case assembly (Fig 40, Item 20) off the three spigots on the front case
(Fig 40, Item 10).
Note: Removal of the ribbon cable and tube between the top case assembly and the front case
is made easier if the top case assembly is separated from the front case first.
14.4 Disconnect the following from between the top case assembly and the front case (Refer to
Figure 40):
• The ribbon cable connector from the top of the power supply PCB assembly.
• The large diameter tube (Fig 40, Item 40) from either the motor and manifold assembly or
the compressor assembly.
14.5 Remove the top case assembly from the front case, and the case style gasket (Fig 40, Item 30)
from the top case assembly.
