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 filter. Replace wet filter.
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.
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/PA20 Series Tychem Hood User Manual
for cleaning instructions for the hood components. Remove
filter and discard (if it has reached the end of its useful life)
in accordance with federal, state and local guidelines and
in conformance with plant safety regulations.
Re-charge the battery pack (see instructions on page 3).
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 to 32º C) with humidity less than 90% RH.
Consult the CC20/PA20 Series Tychem Hood User Manual
