WHEN USED IN HAZARDOUS SUBSTANCE
RECOVERY
WARNING
To reduce the risk of exposure to hazardous substances
you must read and follow all safety instructions in this
Instructions for Use manual.
Attention Employer
· Please ensure the Instructions for Use manual are provided to
and understood by your employees or any other persons who
use this equipment.
· To list all toxic and hazardous substances would be beyond
the scope of these instructions. It is the employer’s and
operator’s responsibility to identify hazardous or toxic substan
ces which may be collected by the equipment during operation.
Such information must be communicated to operators and other
potential users of this equipment.
· This cleaner is designed for recovery and collection of dust,
debris and particulate matter only.
· This cleaner is not suitable for recovery and collection of any
form of hazardous vapors. Do not use the cleaner if these
vapors are present.
· This cleaner is not suitable for recovery and collection of fl am
mable or explosive solvents, chemicals, or liquids. Do not use
the cleaner if these liquids are present.
General Instructions
· Contact with the cleaner, dustbag, fi lter and all other
accessories used when picking-up hazardous materials must
be handled according to federal (EPA, OSHA), state and local
regulations valid for the vacuumed substance.
· Do not use this cleaner for the removal of hazardous
substances unless you are licensed and/or certifi ed for this work
by the all authorities having jurisdiction.
Instructions for Use
· Operation of the cleaner when picking up hazardous substances
must be accompanied by the use of appropriate personal
protective clothing and respiratory protection.
· Do not pick-up hazardous substances without the HEPA fi lter in
place.
· If this vacuum cleaner is used to collect hazardous substances,
do not attempt to open or empty its contents without the use of
personal protective clothing and respiratory protection.
· If the cleaner is not working properly or has been dropped,
damaged, left out doors, or dropped into water, return it to a
qualifi ed service center or dealer.
· This cleaner circulates ambient air for cooling the vacuum motor.
Hazardous particles may accumulate in the internal motor cooling
air ducts and could be released into the exhaust airstream at any
time. If the cleaner is used in an enclosed contaminated
environment, it should be committed exclusively to this type of
environment and not operated outside of an enclosed and
controlled environment.
· Before the cleaner and any accessories are removed from a
controlled environment, all external surfaces must be
decontaminated according to federal (EPA, OSHA), state and
local regulations valid for the vacuumed substance.
Filter Replacement
· All disposed fi lters, bags, and debris should be treated as a
hazardous substance and must be disposed in accordance with
all federal, state, and local regulations.
· Use only approved Euroclean vacuum fi lters and bags.
· The following is a recommended replacement interval for all of
the fi lters and bag. These items should be replaced more often if
you experience a loss of performance.
· Disposable fi lter dust bags – When the bag is 2/3 full it should
be replaced. Excessive over fi lling of this bag makes it diffi cult
to remove from the vacuum tank and can result in breakage and
spills.
· Motor pre-fi lter – This fi lter should be replaced or vacuumed
thoroughly using a HEPA vacuum with every fi fth change of
bag or whenever there is a visible collection of debris on
the fi lter.
Filter basket – This fi lter should be replaced or
vacuumed thoroughly using a HEPA vacuum with every
change of bag or whenever there is a visible collection of
debris on the fi lter.
· Cartridge fi lter – This fi lter should be replaced with every fi fth
change of the pre-fi lter or whenever there is a visible collection of
debris on the fi lter.
· HEPA fi lter – Replace this fi lter at least every six months or more
often if a loss of vacuum continues after you have replaced all
other fi lters and the bag.
How to examine fi lters
· Filters collect and are contaminated with hazardous substances.
The inspection and or replacement of any fi lter must only be
done with the use of personal protective clothing, proper
respiratory protection and in a controlled environment.
· The fi lter basket and the HEPA fi lter cannot be cleaned.
Periodically make a visual inspection of each fi lter for a build-up
of debris or damage to the sealing surfaces. If any fi lter appears
to be clogged, damaged in any way, or has changed color
(HEPA-fi lter should be white) which indicates excessive dirt build-
up, replace with a new fi lter making sure to install new secondary
and primary fi lters.
· If any visible dust particle emissions are observed in the vacuum
exhaust air stream, stop operations immediately. If this occurs,
the HEPA fi lter has ruptured or failed and must be replaced.
Service Instructions
· If this cleaner has been used to pick-up hazardous substances in
an enclosed contaminated environment, the internal components
of the powerhead may be contaminated.
· External decontamination of the cleaner must be carried out.
However, external decontamination will not eliminate any internal
contamination. Any servicing of the powerhead involving
disassembly must be done inside of a contained environment
by trained service personnel using appropriate personal
protective clothing and respiratory protection.
· Any replaced components or debris collected during servicing
should be treated as a hazardous substance and must be
disposed of in accordance with all federal, state, and local
regulations.
· All sealing rings and gaskets should be replaced anytime the unit
is disassembled to assure high machine effi ciency.
