Cleaning the Headgear Assembly
Use a soft cloth to remove dirt and grime. If the headgear requires further cleaning, remove the motor
housing assembly, the head harness assembly, the head seal assembly, the visor assembly, the main
filter, and the expander. Only the headgear shell may be immersed in a mild solution of soap and water.
Rinse the visor assembly with clean running water to remove dirt and shake off the excess water.
Handle the visor carefully to avoid unnecessary scratching. Allow all components to dry thoroughly
before reassembling.
Cleaning the Head Harness Assembly (Headband, Comfort Band, Cradle Assembly) and Head
Seal Assembly (Head Seal, Temple Seal)
Wipe with a cloth dampened with a solution of mild soap and water. Wipe off excess water
and allow to dry prior to reinstallation.
Cleaning the Motor Housing Assembly
In some environments, dust may gradually accumulate within the motor housing, which could reduce
the efficiency of the motor unit. The accumulated dust can be removed by first removing the prefilter
from its compartment and then using a vacuum cleaner to clean the prefilter side of the motor
housing. Do not use a vacuum or compressed air to force air directly through the motor/fan assembly.
This may cause the motor to spin too fast and damage the motor’s bearings.
After cleaning the system, inspect all parts for damage and wear, replacing parts if necessary. Allow
the components to dry completely, away from sunlight and direct heat. Store the system in a clean
area, away from moisture, heat, and direct sunlight. Storage temperatures must not exceed 120°F
(49ºC).
Storage
Store your respirator at room temperature in a dry area that is protected from exposure to hazardous
contaminants.
