ventilator via a metal ducting. The exhaust from the ventilator
must be led outdoors.

PERMITTED SOLVENTS

The unit can be used with solvents and solvent mixtures
intended for spray-gun cleaning, such as acetone, toluene,
isobutanol, xylene that are listed as Group IIA according to
IEC 79-20 (EN 60079-20).
The unit can also be used with water or water based solvents.
All solvents must have a pH value between 4 and 10. Be sure
not to mix water-based solvents with thinner-based solvents.
It is important that all users are informed of what solvent is
being used, at all times.
Never use any solvent if it is not provided with an MSDS (Mate-
rial Safety Data Sheet). Read the MSDS carefully, and follow all
the instructions and procedures provided in the MSDS. If unsure,
or if more information is needed concerning the solvent, please
contact your solvent supplier.
Do not add other chemicals to the solvent including, but not
limited to, kerosene, gasoline, detergents, fuel oil or chlorinated
solvents.

PERMITTED SOLVENT DRUMS

The DRESTER DIX22 can be used with different types of drums,
but they must comply with the following:
– The drums must fit into the unit
– The drums must be leak-free.
– The drums must be made of a conductive material.
– Check for local regulations concerning max allowed volume
for keeping solvent in the unit
Solvent drums are not provided by Hedson Technologies, thus
Hedson Technologies does not take any responsibility for the
drums. Follow the solvent supplier's instructions carefully.

COLLECTING TRAY

The unit must be installed in such a way as to prevent ac-
cidental leakage of solvent from spreading into a drain water
system, thus representing a hazard to the environment. This can
be done by:
– installing the unit in a location where floor and walls can
hold any accidental drum leakage, or
– equipping the unit with a collecting tray beneath the solvent
drums that is large enough to hold the volume of at least
4
one leaking drum.
PREPARATIONS FOR USE
Solvent drums
Remove the front panel (item 7 illustration 1) by lifting it
up-and-out.
Two drums are needed
for each side
that is , and one drum
empty full
each side must be of the same size
requirements described under chapter PERMITTED SOLVENT
DRUMS. Both drums must be clean on the inside and they must
not contain any solids or other objects that could be sucked
into the pumps when running.
Drum plugs
There are several types of solvent drums on the market, each
with different diameter of the opening. With the unit, cardboard
boxes with a selection of tapered plugs are supplied (illustration
6). Select the plugs that fit well into the opening of the drums,
and fit them onto the drum adaptors of the hoses (illustration 7).
Solvent fill-up
Follow the following procedure for the left side of the unit:
Use one empty drum and another drum of the same size full
of clean solvent.
Place the empty drum to the left underneath the unit (item 1
illustration 8). Insert the group of hoses containing the drain
hose from the sink into this drum (item 2 illustration 8). Make
sure that the hoses are properly led well down into the drum,
and that the opening is well sealed by the tapered plug.
Take the second drum, the one full of solvent, and pour half of
its contents directly into the gun cleaner's sink (item 1 illustra-
tion 1). The solvent that is poured in will drain into the drum
underneath the gun cleaner. Make sure to have the ventilation
running during this procedure.
Place the second drum, now half full, on the floor on the right-
hand side of the first drum (item 3 illustration 8). Insert the 6mm
hose into this drum (item 4 illustration 8). Make sure that the
hose is properly led into the drum all the way down to the bot-
tom, and that the opening is well sealed by the tapered plug.
The solvent system is now filled-up on the left side of the unit.
Both drums should be half full. The left-hand drum, contains
the solvent that will be recirculating for the automatic wash cy-
cle, and the right-hand drum contains clean solvent for rinsing.
The contents of the right drum will gradually be used up and
transferred to the left drum.
Now the solvent fill-up procedure
repeat
the unit.
If only recirculating solvent will be used in the machine, put all
of the unit, one drum
of solvent.
Both drums on
, and they must meet the
