NOTE CONCERNING THE RECOVERY OF EXPLOSIVE DUSTS AND OF METAL
DUSTS:
The applicable standards do not specifically regulate the recovery of combustible
dusts and flammable liquids in hazardous areas.
For the recovery of explosive dusts and of metal dusts, in particular, a risk
assessment shall be conducted by the user. The following recommendations
cannot, in any case, supplant the conclusions of a risk assessment.
For the recovery of explosive dusts and of metal dusts:
In the case explosive dusts or metal dusts are mixed with other kind of dusts and
the quantity of explosive dusts or metal dusts to recover is not significant (ex.:
sanding of painted surfaces) the recovered dusts do not need to be rendered inert
in a liquid bath.
For the specific recovery of a significant quantity of explosive dusts or metal dusts
or when these dusts are not mixed with other kind of dusts we recommend the use
of an optional interceptor (model “IT EX”) for the dusts to be rendered inert in a
liquid bath.
WARNING CONCERNING THE INTERCEPTOR:
It is the user’s responsibility to determine the appropriate liquid (water, oil, etc) to
use to neutralize the metal dust in the interceptor.

5.0GROUNDING INSTRUCTIONS
This vacuum cleaner must be properly grounded. If it should malfunction or
breakdown, grounding provides a path of least resistance for electric current to reduce
the risk of electric shock. This vacuum cleaner is equipped with a cord having an
equipment-grounding conductor. The explosion proof vacuum cleaner is supplied
without an electrical plug. It is the user’s responsibility to install a suitable plug certified
for the hazardous locations area classification.
The explosion proof plug should be installed by a qualified electrician only. The plug
must be plugged into an appropriate outlet that is properly installed and grounded in
accordance with all local codes and ordinances. Ensure that the fuse/breaker on the
electrical panel is of the correct rating and exceeds the maximum current rating shown
on the technical data sticker of the vacuum unit. Test the electrical continuity of the
vacuum cleaner prior to each use (see section 6: testing for ground continuity).
UWARNING:UThis vacuum cleaner for hazardous locations is equipped with
conductive wheels, which allow for the vacuum cleaner to be
grounded with the floor. Do not substitute the conductive
wheels and use only replacement conductive wheels supplied
by the manufacturer.
UWARNING:UImproper connection of the equipment-grounding conductor
can result in a risk of electric shock. Check with a qualified
electrician or service person if you are in doubt as to whether
an outlet is properly grounded. If the plug will not fit the outlet,
have a proper plug or outlet installed by a qualified electrician.
No adaptor should be used with this vacuum cleaner

UWARNING:UTo effectively dissipate static electricity and to ensure spark-
free operation, this vacuum cleaner must be grounded during
use.
UDANGER:UDo not operate vacuum cleaner if the electrical outlet is not
properly grounded or if the grounding is questionable.
6.0TESTING FOR GROUND CONTINUITY
UWARNING:UTest the electrical continuity of the vacuum cleaner before each
use. This will ensure that any static electricity that is produced
while vacuuming will be discharged to ground.
UWARNING:UUse only original replacement parts and accessories from the
manufacturer or from one of its authorized distributors.
a. An ohm-meter is required to perform the following electrical continuity test. A
reading of 10 ohms or less is satisfactory to ensure proper grounding and static
dissipation.
b. Disconnect the vacuum cleaner from the electrical outlet.
c. Make sure that all the latches on the vacuum cleaner are fastened and that the
detachable recovery tank is properly installed on the vacuum cleaner.
d. Disconnect the suction hose from the vacuum cleaner.

7.0PRECAUTIONS FOR THE RECOVERY OF LIQUIDS
UIMPORTANT: UThis explosion proof vacuum cleaner is equipped with a
floater mechanism, which automatically cuts-off the
suction when liquids in the recovery tank reach capacity
levels. It is important to note that there may still be some
liquids present in the suction hose after the suction is
cut-off. Both extremities of the suction hose should be
elevated in order to prevent liquids from spilling out. The
suction hose should then be emptied by letting the
liquids drip out into an appropriate receptacle.
UIMPORTANT:UDo not completely submerge the end of the suction hose
(or attachment) in liquid. The explosion proof vacuum
cleaner requires a mixture of air and liquid in order to
function properly. Completely submerging the suction
hose in liquid will create a siphoning effect, which will
cause the vacuum cleaner to continue taking in liquid
even after the floater has activated. This will cause the
vacuum to over-fill and will cause fluid to flow out
through the suction hose.
UNOTE:UIf recovering liquid solutions that foam upon agitation,
use a de-foaming agent. Add the prescribed amount of
de-foaming agent into the recovery tank in order to
prevent foam from entering the powerhead.
