Permitted Solvents; Permitted Solvent Drums; Collecting Tray; Preparation For Use - DRESTER Boxer double Solvent DB21S Manual De Operación

Ventilation
There are three different options for the unit's ventilation.
all three options, it must be ensured that the speed of the
air fl ow at the opening of the hood is at least 0.5 m/s (this
corresponds to a ventilation volume of 500 m
The ventilation must be connected in such a way as to ensure
the grounding of all parts.
Option 1: Connect the fl ange of the hood (item 3 illustration
1) directly to a metal ducting, which is in turn connected to a
ventilation system approved for Zone 1.
Option 2: Fit an air-driven AIRVENT 11660 to the hood and
connect this in turn to a metal ducting. This ducting can either
lead outdoors or be connected to a ventilation system approved
for Zone 1. The ducting must have a smooth inner surface, may
not be longer than 15 metres and shall be installed so that it is
as straight as possible.
Option 3: Connect the hood to an electric ventilator of a kind
like MINIVENT 2050 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.
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
(Material Safety Data Sheet). Read the MSDS carefully, and fol-
low 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 BOXER DOUBLE S 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

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 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 5 illustration 1) by lifting it up-
and-out.
Remove the foot-pedal console (items 6 illustration 1) by lifting
it up and folding it out to the side (see illustration 2).
Two drums are needed, one drum that is
of solvent.
full
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 3). 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 4).
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 2
illustration 2). Insert the group of hoses containing the drain
hose from the sink into this drum (item 4 illustration 2). 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 2 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.
