Subtask 25-31-41-710-051-A ** ON A/C NOT FOR ALL (1) Remove the warning notice(s) from:
- The HP and LP ground air-connectors
- AIR COND panel 30VU
- The water service panel.
H. Operational Test of the Galley Systems
(1) Energize the ground service network (Ref. AMM TASK 24-42-00-861-001).
(2) Do a check of the air supply and air exhaust systems as follows:
(a) Do the pre-conditioning with the APU (Ref. AMM TASK 12-33-21-618-001) or the HP ground connection (Ref. AMM TASK 12-33-21-618-001).
(b) Do the functional test of the applicable air extraction point. Do not de-energize the electrical circuits when the test is completed (Ref. AMM TASK 21-23-00-720-002).
(c) Turn the air outlet clockwise until it is in the closed position.
(d) Make sure that no air comes out from the air outlet.
(e) Examine all the air hoses and the connections for leaks.
(f) If you find leaks, repair them.
(g) Turn the air outlet counterclockwise until it is in the open position.
(h) Make sure that the intensity of the airflow changes when you turn the air outlet.
(3) Do the check of the potable water system and the drain system as follows:
(a) Make sure that the potable water system is filled (Ref. AMM TASK 12-15-38-613-001).
(b) Pressurize the potable water system (Ref. AMM TASK 38-10-00-614-001).
(c) Examine all the potable water hoses for leaks.
(d) If you find leaks, repair them.
(e) Operate the faucet and make sure that water flows.
(f) Let the water flow until it is clean.
(g) Examine all the waste water hoses for leaks.
(h) If you find leaks, repair them.
(4) Do the operational test of the galley electrical system as follows:
(a) On the galley control panel, make sure that all the circuit breakers are closed.
(b) Operate each electrical unit/component for a short time to make sure that it is serviceable.
5. Close-up(1) Energize the ground service network (Ref. AMM TASK 24-42-00-861-001).
