Cleaning The Shoulder Harness And Waist Pad; Storing The Respirator - 3M SCOTT AIR-PAK X3 PRO Operating & Maintenance Instructions

To perform a regulator check
This regulator check is not intended to be a complete functional check of the respirator. Before your next use of the
respirator, perform a regular operational inspection as described in
page 5.
1 Make sure the respirator cylinder is at least 1/2 full to prevent the Vibralert from initiating and obscuring the
sound of air flowing from the regulator.
2 Verify that the air saver/donning switch is depressed on the E-Z Flo+ regulator or the auto air-saver switch is
engaged on the E-Z Flo C5 regulator latch.
3 Close the purge knob.
4 Reattach the regulator to the respirator (if removed for cleaning).
5 Slowly open the cylinder valve at least 1 full turn.
6 If you hear air flowing from the regulator, close the cylinder valve and repeat steps b through d. If you still hear air
flow, close the cylinder valve fully, tag the unit for repair, and remove it from service.
7 Open the purge valve and observe the air flow from the regulator spray bar. Droplets of water indicate the
regulator is not dry. Dry the regulator according to step 8 of
the regulator check.

Cleaning the Shoulder Harness and Waist Pad

You can launder the shoulder harness and waist pad on the Air-Pak X3 Pro in an industrial washing machine. 3M Scott
Air-Pak X3 Pro Inspection and Cleaning Instructions (P/N 595360-01) provides instructions for detaching the
shoulder harness and waist pad from the backframe in preparation for laundering and reattaching them to the
backframe. 3M's recommended laundering practices are also provided. For more information, see
Appendix I: Related Manuals" on page

Storing the Respirator

Respirators intended for routine use and respirators not routinely used but kept for emergency use must be stored in
areas where the temperature is maintained above freezing (32° F / 0° C). If it is necessary to store the respirator at a
temperature at or below freezing before its next use, you must take special care to verify that all components of the
respirator are thoroughly dried.
To prepare the respirator for storage
1 If you notice any damage or deterioration, remove the respirator from service and tag it for repair.
2 Verify that the respirator is thoroughly dry before storing.
3 Attach the regulator to the regulator holder on the waist belt of the respirator.
To detach or reattach a breathing regulator equipped with a quick-disconnect from the respirator, see
the Regulator" on page 10.
NOTE
Do not store the respirator with the regulator attached to the facepiece. Storing the respirator in this way
may damage the facepiece, which could lead to serious injury or death. Attach the regulator to the
facepiece only when you are ready to begin using the respirator.
4 Place the clean and dry facepiece in a breathable storage bag to protect it until its next use. Store it in a manner
that will not distort the face seals.
5 Place the respirator in the carrying case, protective container, or in a suitable storage location.
