  • After initialization, the rectangular indicator lights will show the level of the air supply in the cylinder as follows:

  • FULL: 2 green lights glowing near the center of the display

  • THREE-QUARTERS: single green light glowing.

  • ONE-HALF: yellow light flashing slowly at once a second.

How to don av 3000 mask

How to Don AV 3000 Mask

  • Adjust the head straps to their full outward position.

  • Hold the facepiece in one hand and hold the head harness by the strap at the base of the head net.

  • Place the facepiece on the face with chin properly located in the chin pock­et while pulling the head harness over the top of the head. Verify that no hair or clothing is interfering with the face to facepiece seal. 12 A

  • Tighten the neck straps by pulling the two lower strap ends toward the rear of the head.

  • 12 B


Donning mask

Donning mask…

  • Stroke the head harness net down the back of the head using one or both hands. Verify that the head harness is lying flat against the back of the head. Retighten the neck straps. 12C

  • Tighten the two temple straps. Adjust the temple straps by pulling the two temple strap ends toward the back of the head. Over-tightening may cause discomfort. 12D

  • Retighten the neck straps if required.


Attaching regulator

Attaching Regulator

  • Fully depress the center of the air saver/donning switch on top of regulator and release.

  • The breathing regulator is equipped with an air aver/donning switch to prevent the rapid loss of air supply when the cylinder valve is open and the facepiece is removed from the face or the regulator is removed from the facepiece.


Attaching regulator1

Attaching Regulator

  • If the regulator is not attached to the facepiece, proceed as follows:

    • Verify that the regulator gasket is not damaged and is in place around the outlet port of the regulator.

    • Align the two flats of the regulator outlet port with the corre­sponding flats in the facepiece port (the red purge valve on the regulator will be in the 12 o’clock position). insert the regulator into the facepiece port.

    • Rotate the regulator counterclockwise (as viewed from inside of facepiece) until the red purge valve knob is on the left side of the facepiece. The lock tab on the regulator will lock into the facepiece retainer with a “click.” when the lock tab is properly engaged, the regulator will not rotate.


Attaching regulator2

Attaching Regulator

  • Slowly open cylinder valve fully by turning the valve knob counterclockwise until it stops (approximately 2 1/2 full turns of the knob).


Attaching regulator3

Attaching Regulator

  • Observe the operation of the alarms:

    • The VIB RALERT end of service indicator alarm will actuate and then stop.

    • The HEADS-UP DI SPLAY shall initialize for twenty (20) seconds and then display the cylinder level.

    • The PAK ALERT SE 7 distress alarm will actuate when the cylinder valve is opened and will sound three quick audible chirps accompanied by a green flashing on the PAK ALERT SE 7 control console


Attaching regulator4

Attaching Regulator

  • If the air saver/donning switch has not been depressed prior to opening the cylinder valve, the VIB RALERT Alarm will not actuate due to the air flowing freely on the facepiece.

  • With facepiece sealed to face, inhale sharply.


Scott 4 5 airpack

  • Always check the facepiece seal, the system seal, and the operation of the end of service alarms using the following procedure:

    • Completely close the cylinder valve by pushing in on the cylinder valve and rotating it clockwise.

    • Breathe on respirator. As the air pressure falls in the respirator, one or more of the end of service indicator alarms will actuate.

    • Immediately on actuation of any end of service indicator alarm, hold breath momentarily and make certain that the Vibralert and heads up display both actuate (rapid clicking of the Vibralert Alarm, rapid flashing of the heads up display red light.


Scott 4 5 airpack

  • Resume breathing on the respirator until all air stops flowing from the breathing regulator.

  • NEGATIVE PRESSURE LEAK TEST:

    Inhale slowly and hold breath momentarily. No leakage of air shall be detected into the facepiece and the facepiece shall be drawn slightly to the face.

  • Open cylinder valve and breathe normally. If installed, the electronic end of service time indicator will continue briefly then stop.


Use in standby mode

Use in Standby mode

  • The respirator may be donned and worn in "Standby," so that it is ready for use. This means the respirator is in place on the user’s body with the shoulder straps properly adjusted and the waist belt buckled, but the facepiece is not donned (sealed to the face) and the respirator is not being used.


Scott 4 5 airpack

  • Leave the cylinder valve fully open and verify that the air saver/donning switch is depressed.

  • Remove the facepiece but leave the regulator attached to the facepiece.

  • Keep the facepiece ready for use either of two ways:

    • Hang the facepiece from the snap clip on the left shoulder pad,

    • Hang the facepiece from the optional neck strap.

  • NOTE DO NOT LET THE FACEPIECE HANG LOOSE WI THOUT SECURING ITAS NOTED ABOVE.


Scott 4 5 airpack

  • The regulator can be detached from the facepiece until needed. To detach the regulator from the facepiece:

    • Place your right hand over the cover with your thumb on the lock tab.

    • Pull the lock tab toward the cover and rotate the regulator ¼ turn clockwise (viewed from inside of facepiece).

    • W hen the red purge valve is in the 12 o’clock position remove regulator from the facepiece.

    • The regulator can be stored in the optional regulator holder on the waist belt.

Cleaning

Cleaning

  • Respirators must be cleaned after every use

  • We use a solution to clean the mask

  • We are not cleaning them as frequently as we need to. They carry carcinogenic remnants of fires.
