Permitted Solvents; Permitted Solvent Drums; Collecting Tray - Hedson Drester Boxer triple C Manual De Operación

To prevent pressure drops, the air line and couplings must be
adequately dimensioned. The regulator on the unit is pre-set to
6.5 bar (100 psi). This is the optimal setting and must not be
altered.
The compressed air supplied to the unit must be clean and dry.
If it is not fi rst led through a water trap and fi lter, it may cause
damage to the pneumatic components of the unit, which will
invalidate any warranty claims.
Fit a connector to the air-line on the left side of the unit (item 4
illustration 1). This air-line is intended to blow out the spray-
gun after the cleaning procedure.
Grounding the unit
Make sure that the unit is properly grounded by using the
grounding cable (item 6 illustration 2).
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 400 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 left side of the unit
This side 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). Also water or water based solvents can
be used on this side.
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.
The right side of the unit

be used.
General
3 /h (250 cfm)).
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.

PERMITTED SOLVENT DRUMS

The DRESTER BOXER TRIPLE C 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 acciden-
tal leakage of solvent or contaminated water 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 sol-
vent drum and water container that is large enough to hold
the volume of at least one leaking item.
