- If necessary clean the grill(s) and the housing(s) with a vacuum cleaner.

- If necessary replace the air extraction filter(s) (Ref. AMM TASK 25-30-00-960-002).

(3) Hold a suitable sized piece of paper to the applicable air extraction inlet(s). The paper will stay in position at the air extraction inlet(s) by the air suction.

(4) Install the removed oven (Ref. AMM TASK 25-35-19-400-001) or steam-oven (Ref. AMM TASK 25-35-19-400-003).

4. Fault Isolation
_______________

A. If the test gives a different maintenance message:
- Do the trouble shooting procedure related to the maintenance message.
B. If the test gives the maintenance message SLIDE BOTTLE FWD L, or DEU-B 300RH1:
- make sure the gage needle of the inflation reservoir pressure-gage is positioned over the green cursor, or to the right of the green cursor.
NOTE : The green cursor of the pressure gage is temperature compensated,
____ and reacts to temperature changes faster than the gas expansion in the inflation reservoir. The green cursor moves independently of the gage needle, when a temperature change occurs.
(1) If the pressure indication is not correct:

- replace the ESCAPE SLIDE FWD L (7500MM), (Ref. AMM TASK 25-62-44-000-002) and (Ref. AMM TASK 25-62-44-400-001).

(2) If the pressure indication is correct:

- replace the DEU-B (300RH1), (Ref. AMM TASK 23-73-47-000-001) and (Ref. AMM TASK 23-73-47-400-001).

(3) If the fault continues:

- do a check and repair the wiring between the: DEU-B (300RH1) connector C/36 and the SLIDE BOTTLE PRESS SENSOR connector A/C (Ref. ASM 25-65/01) and (Ref. ASM 23-73/11).
C. Do the test as given in paragraph 3. A. to check the correct operation (no maintenance message is shown).
