A. Check of the Pressure.
(2) Do a check of the pressure:
(a) Write the pressure value shown on the pressure gauge (1).
(b) Compare this value with the value on the placard (2) for the ambient temperature.
5. Close-upCAUTION:
THE PRESSURE ON THE PRESSURE INDICATOR OF THE BOTTLE MUST BE RELATED TO THE PRESSURE CORRECTED FOR TEMPERATURE.
(1) Make sure that the door is open. (2) Do a check of the pressure:
(a) Write the pressure value shown on the pressure gauge (1).
(b) Compare this value with the value on the placard (2) for the ambient temperature.
NOTE: The minimum operating pressure value for the door to be serviceable is 1305 PSI at 20°C only for maintenance operation.
NOTE: To get a correct pressure, the air bottle must be stable at ambient temperature before you do the inspection.
NOTE: Bubbles in the pressure gauge with a maximum diameter equal to the dial are permitted.
(3) If the pressure is not correct, charge the cylinder bottle. (Ref. AMM TASK 52-10-00-614-001)Subtask 52-10-00-410-088-A
