Cleaning And Storage; Replacement Part Instructions - 3M 7000 Serie Instrucciones De Uso

Cleaning and Storage

Cleaning is recommended after each use.
Do not clean respirator with solvents. Cleaning with solvents may degrade some respirator components and reduce respirator effectiveness.
Inspect all respirator components before each use to ensure proper operating condition. Failure to do so may result in sickness or death.
1. Remove cartridges, filters and/or breathing tubes. The center adapter, lens and faceseal can also be removed if necessary.
2. Clean facepiece (excluding filters and cartridges), by immersing in warm cleaning solution, water temperature not to exceed 120°F (49°C), and
scrub with soft brush until clean. Add neutral detergent if necessary. Do not use cleaners containing lanolin or other oils.
3. Disinfect facepiece by soaking in a solution of quaternary ammonia disinfectant or sodium hypochloride (1 oz [30 mL] household bleach in 2
gallons [7.5 L] of water), or other disinfectant.
4. Rinse in fresh, warm water and air dry in non-contaminated atmosphere.
5. Respirator components should be inspected prior to each use. A respirator with any damaged or deteriorated components should be repaired or
discarded before use.
6. The cleaned respirator should be stored away from contaminated areas when not in use.

REPLACEMENT PART INSTRUCTIONS

Respirator parts should be inspected prior to each use. Replace worn or deteriorated parts with new parts before use.
3M™ Lens 7884
The lens should be inspected for cracking or crazing. Replace if necessary. Replace as follows: Remove two screws on either side of lens with a
Phillips screwdriver, remove the top and bottom lens frame and remove the lens. To reassemble, first align the center of the lens with the centerline
of the facepiece. The center of the lens is marked by two small lines, one at the top center and second at the bottom center of the lens. Place the lens
into the facepiece and then reattach the lens frame. Replace the two center screws and tighten.
3M™ Exhalation Valve Cover 7918 and Exhalation Valve 7283
Remove the 3M™ Exhalation Valve 7918 cover by lifting out on the two top prongs on either side of the center opening and sliding down. Remove the
exhalation valve by grasping and pulling on the edges of the valve. Replace the valve if it is warped, distorted, cut, split or if it will not seal tightly on
the valve seat. Replace by pushing the valve onto the exhalation valve post.
3M™ Speaking Diaphragm Kit 7895
Remove the nose cup. Using the diaphragm removal tool, turn diaphragm retaining ring counterclockwise and remove. Push diaphragm assembly
out of the facepiece from underneath using the eraser end of a pencil or a similar object. Check the speaking diaphragm gasket for damage or
deformation. To replace the diaphragm, follow the steps in reverse.
NOTE: The grill pattern with deep indentation in the center should be visible from inside the respirator.
3M™ Removable DIN Connector 7886
Hold the inside part of the connector secure, grasp the outside of the connector and twist counterclockwise to remove. To replace the connector,
press the inner section into the facepiece until the end of the threads are flush with the facepiece exterior, then screw on the outer piece by turning
clockwise.
3M™ Inhalation Valves 7282
Grasp the edges of the valve and pull away from the plastic post. Replace if the valve is distorted, cut, split or cannot be sealed on the valve seat. If
the valve seat is damaged, replace the removable DIN connector 7886.
3M™ Air Inlet Gasket 7999
Remove the gasket from the air inlet opening base. Replace the gasket if it is warped, distorted, cut, split or cannot be reassembled into the air inlet.
To replace, position the gasket so the small cut-out on the gasket is pointing toward the lens. Push the gasket groove onto the plastic bar and seat the
gasket.
3M™ Inhalation Port Gaskets 7887
Remove the gaskets from each side of the facepiece. Replace the gaskets if they are warped, distorted, cut or split. Replace one gasket on each side
of the facepiece. Be sure the gasket is flat and seated correctly.
