Disconnect the up-stream hose from the isolator switch to allow any residual
pressure in the system to vent. Reconnect the up-stream hose.
15. Ensure that the mid plate assembly has free movement. Lift the assembly
and allow to drop, checking that it drops under its own weight back to its
original position.
