ACTION RESULT -------------------------------------------------------------------------------
-push the BLEED pushbutton - the BLEED page comes on,
switch. - the temperature control valves position needles (2) show green and move to the open (H) positions,
-the pack outlet temperatures (3) show a maximum of 70 deg.C .
7. On the AIR COND panel 30VU: On the SD (BLEED page):
-put the COCKPIT, the FWD CABIN - the temperature control valves and the AFT CABIN temperature position needles (2) show green and selectors to the COLD position move to the closed (C) positions, 18 deg.C and wait for apprx. 3 - the pack outlet temperatures (3) minutes. decrease,
(the lowest pack outlet temperatures reached are dependant upon the outside air temperature).
8. On the ECAM control panel: On the SD:
-push the COND pushbutton - the COND page comes on,
switch. If the actual temperature is more than the selected temperature, or the duct temperatures are more than the allowed lower duct temperatures then,
-
the trim air valves position needles
(4)
show green and move to the closed
(C)
positions,
-
the CKPT, the FWD and the AFT zone temperatures (5) decrease.

NOTE : Make sure that the cabin doors and the cockpit windows are closed
____
when you do the test.
NOTE : Due to low pressure in the trim system, with fully closed trim air
____ valves the trim-air pressure regulating-valve symbol (6) can be indicated as closed and show amber. You must ignore this indication for the purposes of this test.

1. On the ECAM control panel:
-push the BLEED pushbutton
switch.
2. On the AIR COND panel 30VU:
-put the COCKPIT, the FWD CABIN and the AFT CABIN temperature selectors to the mid (12 o'clock) position (24 deg.C
(75.20 deg.F)).
3. On the ECAM control panel:
-push the COND pushbutton
switch.
4. Wait until the CKPT, the FWD and the AFT zone temperatures (5) have stabilized at 24 deg.C
(75.20 deg.F).
5. On the AIR COND panel 30VU:
-put the COCKPIT, the FWD CABIN and the AFT CABIN temperature selectors to the HOT position ( 30 deg.C (86.00 deg.F)).
On the System Display (SD):
-
the BLEED page comes on,
-
the pack flow-control valves symbols
(1) move to the open positions and show green.
On the SD:
-
the COND page comes on.
On the SD (COND page):
-
the CKPT, the FWD and the AFT zonetemperatures (5) are shown in green.
On the SD (COND page):
-
the trim-air pressureregulating-valves symbols (6) showgreen and open.
-
the trim-air valves position needles
(4) show green and open to a maximum
of 80%, then start to close if,
the target temperature is reached or
if,
the duct temperature limits are
reached.
