 J. Operational Test of the Galley Systems
 (1)
 Make sure that the aircraft electrical power is energized (Ref. TASK 24-42-00-861-001).

 (2)
 Do a check of the water system:

 (a)
 Pressurize the potable water system (Ref. TASK 38-10-00-614-001).

 (b)
 Examine all the potable water pipes for leaks. NOTE : Leaks are not permitted.

____

 (c)
 Operate the water faucet and make sure that water flows.

 (d)
 Examine the drain hose for leaks.
 NOTE : Leaks are not permitted.

____

 (e)
 Depressurize the potable water system (Ref. TASK 38-10-00-614-002).

 (3)
 Do a check of the electrical system:

 (a)
 Push the pushbutton switch 2XA GALLEY on the overhead panel 35VU in the flight compartment.

 (b)
 Make sure that the POWER indicator light on the galley electrical panel comes on.

 (c)
 Make sure that all the circuit breakers on the galley electrical panel are closed.

 (d)
 Operate each electrical unit/component for a short time to make sure that it is serviceable.

 (e)
 For example, the galley worklight: 1 Push the worklight switch ON, the switch illuminates: the

_
 worklight goes ON.

 2 Push the worklight switch again, the switch-brightness goes
_
 out: the worklight goes OFF.

 (f)
 Release the pushbutton switch 2XA GALLEY on the overhead panel 35VU in the flight compartment.

 (g)
 Make sure that the POWER indicator light on the galley electrical panel goes off.

 (4) Do a check of the air supply- and the air exhaust systems:
 (a)
 Do the pre-conditioning with the APU (Ref. TASK 12-33-21-618-001) or do the pre-conditioning through the HP ground connection (Ref. TASK 12-33-21-618-001).

 (b)
 Do the functional test of an air extraction point (Ref. TASK 21-23-00-720-002), leave the electrical circuits energised if the test is over.

 (c)
 Turn the individual air outlet clockwise until it is in the closed position.

 (d)
 Air must not come out from the individual air outlets.

 (e)
 Examine all the air pipes and the connections for leaks.

 (f)
 Repair all leaks.

 (g)
 Turn the individual air outlet counterclockwise until it is in the open position.

 (h)
 Make sure that different airflow is possible when you turn the individual outlet.
