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.


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

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.

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.

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.

Slowly open cylinder valve fully by turning the
valve knob counterclockwise until it stops
(approximately 2 1/2 full turns of the knob).

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

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.

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.
◦ 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.

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.



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 IT AS NOTED
ABOVE.

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.
