GENERAL ASSEMBLY INSTRUCTIONS
WARNING:
DO NOT PLUG POWER
CORD INTO POWER OUTLET; MAKE
SURE PLUG IS DISCONNECTED BEFORE
ASSEMBLING THE WET/DRY VAC.
This HEPA vacuum is supplied with a certified
HEPA filter that has been tested by an
independent lab to IEST-RP-CC001 that meets
the EPA's definition of a HEPA vacuum (must
be capable of trapping 99.97% of particles
down to 0.3 microns in diameter). It can be
used to pick up materials like sawdust and
gravel, as well as ultra fine materials like
drywall dust and cold fireplace ash.
CAUTION:
This vacuum has been
specically designed to clean up hazardous
dust. Special lters reduce the incidence of
airborne dust that would be created by other
methods of cleaning. During the removal
of hazardous dust, DO NOT sweep, scoop,
shovel or in any manner handle other
than by vacuuming. DO NOT at any time
attempt to substitute or alter the filters
in this vacuum. Never operate without
filters in place. Use only manufacturer’s
approved vacuum filters and filter bags.
Before attempting to use or before cleaning
with this vacuum, be sure that you fully
understand the instructions for setting
up and cleaning/changing filters. Any
health hazards associated with use of this
vacuum in conjunction with the removal
of hazardous material has not been
investigated by Underwriters Laboratories,
Inc.
