1. Reason for Change

Implementation of this FCO will solve problems of noise from the vacuum valve and leakages.

2. Description of Change

Replace the old valve with a new and improved one.

3.1   Switch off the power to the machine via the main switch.
3.2   Open the lower back panel after pulling out the main power cord and the four screws that hold the back
        panel to the main frame.
3.3   Release the two clamps that hold the black flexible hoses to the straight adaptor on the valve (do not
        attempt to open the straight valve from its thread).
        Do it for both valves.
3.4   Disconnect the connector of the fit which contains the wiring.
3.5   Open the nut 3/8" which holds the vacuum valve to the main frame.
3.6   Pull out the flexible hose which connects the vacuum detector to the valve.
3.7   Remove the old valves.
3.8   The new valve holding it is different. Insert the new valve in its place and secure it with the supplied screw,
        spring washer and nut.
3.9   Connect the flexible hose from the vacuum detector (the detector itself is not installed).
3.10 Connect the mini fit connector which connects the wiring to the valve.
3.11 Connect the flexible hoses to the valves and tighten the clamps.

4. Test Procedure

4.1 Activate the pump several times and check for good and smooth operation.
