3.4.4 Removal of the Main Board and Power Supply board from the chassis
To remove the Main and Power Supply boards from the chassis, the valve control and pump connector
must first be removed. This is visible through the hole in the rear of the chassis.
The chassis spade terminal must also be removed. This is located between the top of the chassis and the
Power Supply board (Unit revision 06 only).
Disconnect pneumatic hose from pump assembly to Main Board secondary pressure transducer on revision
06 units. (Disconnect pressure sensor cable on earlier revisions)
The boards can now be slid together up and out of the pcb guides built into the metalwork of the chassis.
