Figure 38 Rotating Camber Door
Warning: Use extreme caution when rotating the chamber door. Catching fingers,
hands, hair, articles of clothing, or other objects in the door may result in personal
injury or damage to the fill station.
7 Close and lock the charging chamber door handle. The door is locked when the
Yellow lock bars are visible around the door frame.
8 Open the Manual Air Flow On/Off Knob 1/8 to 1/2 turn counterclockwise to begin
filling the cylinders.
9 Consult the cylinder manufacturer and the appropriate government regulatory
agency for fill rate recommendations. Do not exceed the fill rate recommendations
for the breathing air cylinders being filled.
Warning: Do not exceed the recommended fill rate for the breathing air cylinders.
Failure to follow this warning may result in catastrophic failure of the cylinder,
leading to serious personal injury or death.
10 Adjust the fill rate as follows:
a Slowly turn the Manual Air Flow On/Off Knob counterclockwise to increase
the rate at which the cylinders are filled.
b Watch the pressure reading on the breathing air SCBA Cylinder Pressure
Gauge.
c If the fill rate is too high, turn the Manual Air Flow On/Off Knob fully
clockwise to decrease the flow, then slowly turn the Manual Air Flow On/Off
Knob counterclockwise to adjust to the proper rate.
d Once fill pressure and fill rate are set for charging cylinders of the same
pressure rating, minor readjustment may be necessary as the storage and
compressor pressures will vary during multiple breathing air cylinder fills.
11 Leave the fill pressure and fill rate set when charging several cylinders that require
the same fill pressure and fill rate. Minor adjustments may be necessary during
filling of successive cylinders depending on the compressor system used.
