e) Thoroughly wash the facepiece and components in the cleaning solution. A soft bristle (not wire) brush or sponge may
be used to clean the facepiece. Be sure to clean under the exhalation valve.
f) Disinfect the facepiece and components by submerging the facepiece and components for the recommended time
period.
g) Rinse the facepiece and components in clean, warm (110°F), preferably running water. Drain.
NOTE:
If not rinsed thoroughly, cleaning agent residue may irritate the wearer’s skin.
h) The facepiece and components should be air-dried or hand dried with a clean lint-free cloth.
WARNING!
Do not force-dry the parts by placing them in a heater or direct sunlight. This will cause the respirator to deteriorate.
Failure to follow this warning can result in serious personal injury or death.
i) After the facepiece is dry, inspect the facepiece thoroughly for missing or damaged parts. Reinstall the exhalation
valve cover. Install the nosecup (if used) and a new cover lens (if used). The facepiece may be stored in a clean
storage bag to protect from contamination until the next use.
WARNING!
Do not use alcohol as a germicide, because it may deteriorate the rubber.
Failure to follow this warning can result in serious personal injury or death.
(5)
Use a damp cloth or sponge saturated with Confidence Plus cleaning solution or an equivalent solution to wipe the motor-
blower and battery pack housing and battery cable clean.
WARNING!
Do not place the motor-blower or battery pack in any liquid. The blower impeller can be loosened or the motor shaft can be
bent. If the motor-blower is dropped, check the housing for cracks. Listen closely to the motor. If the impeller binds or rattles, or
if air output is reduced, the entire motor-blower must be returned to MSA for repair.
Failure to follow this warning can result in serious personal injury or death.
(6)
Clean the support belt. Thoroughly wash and rinse the support belt in the Confidence Plus cleaning solution or an
equivalent cleaning solution. A soft brush or sponge may be used.

Respirator Storage
The battery pack (P/N 10090978) should be stored within a temperature range of 50° to 85°F. If the battery pack has been
stored in a "full charged" condition for more than one week, the battery pack should be charged until a full charge is indicated.
Higher temperatures will shorten battery life. Lower temperatures will decrease capacity and operating time will be reduced.
The other OptimAir MM PAPR components can be stored at temperatures of 0°F to 120°F.

Test Method for the OptimAir MM PAPR
The test method should only be used if any one of the OptimAir MM PAPR components (charger, battery pack, or motor-
blower) is not functioning properly. This method will outline the steps needed to evaluate the proper electrical functions of each
of the components of the MM PAPR. A digital multimeter is required.
