MAINTENANCE
2.1 MARKING OF COMPONENT PARTS
Many of the parts are marked with the letters listed in appendix A for easy identification should they
need replacement. The band is marked with a progressive code that identifies the production lot.
2.2 CLEANING
For optimum longevity of the mask and the proper functioning of its parts we recommend
rinsing the mask thoroughly in fresh water after every use. DO NOT clean the visor with any
abrasive materials. We recommend drying the visor, especially the inside parts, with a soft,
clean cloth.
2.3 STORAGE
The mask must be stored in a dry place with no direct sunlight and far from sources of heat. Do not
store it at temperatures below -4°F (-20°C) or above +122°F (+50°C). We suggest you use the AC-4
visor protector and the carrying bag included in the package when storing the mask to avoid
accidental abrasion (see section 2.4.3) .
