4. Procedure
Subtask 30-21-00-710-066-B ** ON A/C NOT FOR ALL

A. Operational Test of the Engine-Air-Intake Ice Protection

ACTION	RESULT
1.On the ANTI ICE section of the panel 25VU: Push the ENG1(2) pushbutton switch.	On the ANTI ICE section of the panel 25VU, on the ENG 1(2) pushbutton switch: The ON legend comes on. The FAULT legend comes on for a short time during movement of the valve (the anti-ice valve of the engine air intake opens). NOTE: When the anti-ice valve opens, the N2 value increases automatically by approximately 10% to supply the necessary pressure. On the upper ECAM DU: The ENG A.ICE message comes into view. On the MEMO section, the IGNITION message comes into view.
2.On the ANTI ICE section of the panel 25VU: Release the ENG1(2) pushbutton switch.	On the ANTI ICE section of the panel 25VU, on the ENG 1(2) pushbutton switch: The ON legend goes off. The FAULT legend comes on for a short time during movement of the valve (the anti-ice valve of the engine air intake closes). On the upper ECAM DU: The message goes out of view.
