Permitted Solvents; Permitted Solvent Drums; Collecting Tray; Preparation For Use - Hedson DRESTER X Serie Manual De Operación

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 un-
sure, 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 X-SERIES 11M can be used with different types of drums,
but they must comply with the following:
– The drums must fi t 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 accidental
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 fl oor 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
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, one drum that is
of solvent.
full Both drums must be of the same size
must meet the requirements described under chapter PERMIT-
TED 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, card-
board boxes with a selection of tapered plugs are supplied (see
illustration 6). Select the plugs that fi t well into the opening of
the drums, and fi t them onto the drum adaptors of the hoses
(see illustration 7).
Solvent fi ll-up
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 fl oor on the
right-hand side of the fi rst 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 bottom, and that the opening is well sealed by the tapered
plug.
The solvent system is now fi lled-up. Both drums should be half
full. The left-hand drum, contains the solvent that will be recir-
culating for the automatic wash cycle, 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.
If only recirculating solvent will be used in the machine, put all
the hoses for each washing compartment into the same drum
(Illustration 9).
Operating instructions
Operating instructions should be formulated on the basis of
this manual and translated into the language spoken by the
employees. It should always be available close to the machine.
To avoid confusion, the employees must be informed about
the solvent currently being used in the machine.
