1.5.1 Safety instructions on installation and ambient conditions
Familiarize yourself with the local conditions, particularly allocation to a defined potentially explosive area
(zones) and the relevant technical safety requirements. During installation, commissioning and operation
of the vacuum drying oven and the connected vacuum pump or in-house vacuum supply, always follow
the requirements defined by the installation site.
CAUTION
Danger of overheating.
Damage to the unit.
∅
Do NOT install the oven in unventilated recesses.
 Ensure sufficient ventilation for dispersal of the heat.
Do not operate the vacuum drying oven VDL in hazardous locations.
DANGER
Explosion hazard.
Danger of death.
∅
Do NOT operate the unit in potentially explosive areas.
 KEEP explosive dust or air-solvent mixtures AWAY from the unit.
The vacuum drying ovens were constructed in accordance with the applicable VDE regulations and were
routinely tested in accordance with VDE 0411-1 (IEC 61010-1). The production underlies an internal moni-
toring according to ATEX Directive 94/9/EC appendix VIII.
Even when the equipment is used properly, there exists a residual risk of explosion that cannot be exclud-
ed, particularly in relation to the environment of the unit. To minimize this risk, strictly observe the legal
regulations about how to select an appropriate location.
DANGER
Explosion hazard.
Danger of death.

Strictly observe the legal regulations about how to select an appropriate location.
1.5.2 Safety instructions on vacuum supply
Pertaining to units that will be operated in potentially explosive areas, the requirements of ATEX Directive
94/9/EC have to be met as of July 1, 2003.
If combustible solvent is introduced into the drying chamber, the vacuum pump must be constructed in a
suitable explosion-proof manner.
Observe the safety instructions of the pump manufacturer.
The mixtures extracted from the inner chamber must be carried away making sure that there is no danger
by ignition of these atmospheres. Otherwise, use flame arresters (flame flash-through barrier). For in-
stalling a flame arrester, please contact the BINDER INDIVIDUAL team.
In case of an explosion, the flame can be suctioned into an in-house vacuum system thereby resulting in
further explosions.
