Cleaning
Avoid contaminant entry into the breathing tube, as this will
compromise respiratory protection and could result in death or
serious injury. Consult your local safety professional if you
suspect that contaminant has entered the breathing tube. When
cleaning the equipment, do the following:
Ensure water does not enter cartridges. Replace wet cartridges.
DO NOT
use gasoline, organic-based solvents, or chlorinated
degreasing fluids (such as trichloroethylene) as they will cause
damage.
DO NOT
immerse the equipment in water or other cleaning fluid
as this may cause contamination in the breathing tube and
blower interior that will be difficult to remove.
Failure to observe the instructions and warnings in this manual
invalidates all performance statements and approvals for this
equipment and could result in death or serious injury.
Once cartridges have reached the end of their useful life, discard
in accordance with federal, state, and local guidelines, and in
conformance with plant safety regulations.
Use a lint-free cloth moistened in a mild solution of soap and warm
water to clean the outer surface of the equipment.
Consult the CC20/RT Series Tychem Hood User Manual for
cleaning instructions for the hood components.
Storage
When the apparatus is completely dry, store in a clean, dry area,
away from direct sunlight and sources of direct heat.
The storage temperature should be between 32º F to 90º F (0º C
