NOTICE
Danger by stacking.
Damage to the chambers.
∅ Do NOT place vacuum drying ovens on top of each other.
Zulässige Bereiche
The VDL vacuum drying oven may be installed in areas in which explosive atmospheres may occur on a
rare and temporary basis. The entire chamber with the exception of the power plug is classified in catego-
ry 3 in relation to the environment. The chamber plug (power plug) is unprotected, therefore the electrical
connection must be established outside a zone.
VDL vacuum drying ovens are not intended for installation in a Zone 1 or 0. The chamber must not be
installed or operated in an occasionally or continuously / for long periods / frequently potentially explosive
area. Measures must be taken to prevent the spread of explosive atmospheres to unprotected areas.
Spreading of an explosive atmosphere to the unprotected areas must be reliably prevented. Observe the
information on zone classification (chap. 3.6).
Observe the instructions on extraction (technical ventilation , chap. 5.2.2). When installed as intended,
there is no Zone 1 or 0 in the vicinity of the chamber.
DANGER
Explosion hazard by penetration of an explosive atmosphere to unprotected areas.
Serious injury or death from burns and / or explosion pressure.
∅ Do NOT operate the chamber in in occasionally or continuously / for long periods / fre-
quently potentially explosive areas. It is not intended for installation in a zone 1 or 0.
Make sure that there are NO combustible dusts in the vicinity of the chamber
Make sure that air-solvent mixtures are NOT occasionally or continuously / for long
periods / frequently in the vicinity of the chamber.
Strictly observe the relevant legal regulations about how to select an appropriate locati-
on.
The operator is responsible for the correct installation of the pump or other equipment (zone classificati-
on). Sufficient extraction (technical ventilation, chap. 5.2.2) also in the event of an error (e.g. damage /
overfilling the condensate catchpot of the pump, or spilling or dropping containers or material to be loaded
with solvents) must be provided.
If no pumps are used for pumping from zone 0 or 1, i.e. if the vacuum pump is only suitable for category 3
/ zone 2, annual logged maintenance of the pump must be carried out, otherwise measures for an explo-
sion-preventing decoupling (explosion barrier, flame arrester, flame flash-through barrier acc. to EN ISO
16852:2017) between the inner chamber and the vacuum pump are required.
Follow country-specific regulations for explosion protection.
If you ordered the optional pump module with chemical membrane pump, the vacuum pump will be de-
livered in a separate box and must be fitted into the module and connected at the place of installation
(chap. 6.4.3).
