3. Job Set-up
Subtask 30-11-00-941-067-A

A. Safety Precautions
(1) As necessary, use the applicable SAFETY BARRIERS, specified by the operator's instructions and your local regulations.
(2) Make sure that the ground safety locks are installed on the landing gear (Ref. AMM TASK 32-00-00-481-001).
(3) Put WARNING NOTICE(S) in the cockpit to tell persons not to operate the slats and the pneumatic systems.

Subtask 30-11-00-860-059-C ** ON A/C NOT FOR ALL

B. Aircraft Maintenance Configuration
(1) Install the 98D27803500001 LOCKING TOOL ZERO POS on the slat/flap control lever.
(2) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002) or (Ref. AMM TASK 24-41-00-861-002).

NOTE: You can do the Operational Test of the Wing Ice-Protection System with a bleed air supply from one of these sources:

Two engines
The Ground Air Power Cart (GAPC)
The APU.

NOTE: If GTCP 36-300 APU is installed on your aircraft, do not use the GTCP 36-300 APU bleed air supply to do the test. The GTCP 36-300 APU bleed air system does not supply sufficient pressure for the test procedure.

NOTE: Access to the wing anti-ice system on the CFDS is through the TEMP CTL of the air-conditioning class 3 faults (Ref. TSM Chapter 21).

(3) Do the EIS start procedure (ECAM only) (Ref. AMM TASK 31-60-00-860-001).
(4) On the ECAM control panel (CP), push (in) the BLEED P/BSW.
(5) If the source of power is the aircraft engines:
(a) Operate Engine 1 and Engine 2 (Ref. AMM TASK 71-00-00-710-003).
(b) On the AIR COND panel 30VU, put the X BLEED switch in the OPEN position.
(c) Make sure that the bleed air pressure is between 2.8 bar (40.6 psi) and 3.2 bar (46.4 psi).

WARNING: MAKE SURE THAT THE ENG MASTER LEVER IS SET TO THE OFF POSITION. DO NOT SET THE ENG MASTER LEVER TO THE ON POSITION. THERE IS A RISK THAT THE ENGINE WILL START AND THIS CAN CAUSE INJURIES TO PERSONS.

(6) If the source of power is the Ground Air Power Cart (GAPC):
(a) On the AIR COND panel 30VU:

Release (out) the PACK 1 and PACK 2 P/BSW's
Make sure that the OFF lights are on.

(b) Open the access panel 191DB.
(c) Connect the GAPC to the HP connection.
(d) Operate the GAPC to give a bleed air supply.
(e) On the AIR COND panel 30VU, put the X BLEED switch in the OPEN position.
(f) Make sure that the bleed air pressure is between 2.8 bar (40.6 psi) and 3.2 bar (46.4 psi).

(7) If the source of power is the APU:
(a) On the AIR COND panel 30VU:

Release (out) the PACK 1 and PACK 2 P/BSW's
Make sure that the OFF lights are on.

(b) Start the APU:

For the APS 3200 APU (Ref. AMM TASK 49-00-00-860-005).
For the 131-9(A) APU (Ref. AMM TASK 49-00-00-860-008).

ACTION	RESULT
1.On overhead panel 25VU:
Put the ANN LT switch to the TEST position.	On overhead panel 25VU: The cockpit-panel pushbutton-switch legends come on. The FAULT and ON legends of the ANTI ICE WING pushbutton switch come on.
Put the ANN LT switch to the BRT or DIM position.	The FAULT and ON legends of the ANTI ICE WING pushbutton switch go off.
Push the ANTI ICE WING pushbutton switch.	The ON legend of the ANTI ICE WING pushbutton switch comes on. The FAULT legend of the ANTI ICE WING pushbutton switch comes on momentarily when the Wing Anti-Ice (WAI) valves open, and then it goes off.
	On the ECAM lower DU: The left and right ANTI ICE legends come on. In less than 3 seconds, the left and right ANTI ICE symbols come on (green). After 10 seconds, the left and right ANTI ICE symbols become amber. After 31 seconds, the ANTI ICE legends and symbols go off.
Release the ANTI ICE WING pushbutton switch.	On overhead panel 25VU:
	The ON legend of the ANTI ICE WING pushbutton switch goes off. The FAULT legend of the ANTI ICE WING pushbutton switch comes on momentarily when the WAI valves close, and then it goes off.
