•
The grounding plan / equipotential bonding prevents sparking
•
The operator is responsible for the correct installation. He must ensure active extraction (technical
ventilation) when emptying the condensate catchpot of the pump (with or without a pump module)

Spring-mounted safety glass panel
The VDL vacuum drying oven is equipped with a large-surface area safety valve. The inspection win-
dow, consisting of ESG glass (toughened safety glass), is adjustable spring-mounted and serves as a
safety valve in the event of explosion. The laminated safety glass pane provides splinter-protection.

Indications on the type plate
For Ex classification, temperature classes and electrical data, please refer to the operating manual
Chap. 1.6.
•
Operating manual
An operating manual is available for each chamber.
•
Temperature monitoring; safety, measurement, and control equipment
The chamber is equipped with a temperature display, which can be read from outside.
The safety, measuring, and control equipment is easily accessible.
•
Non-ionizing radiation
Non-ionizing radiation is not intentionally produced, but released only for technical reasons by electri-
cal equipment (e.g. electric motors, power cables, solenoids). The machine has no permanent mag-
nets. If persons with active implants (e.g. pacemakers, defibrillators) keep a safe distance (distance of
field source to implant) of 30 cm, an influence of these implants can be excluded with high probability.
•
Safety controller (temperature safety device class 2)
Temperature limitation via the controller by the safety controller serves to protect the vacuum drying
oven, its environment and loading material against impermissible temperature exceeding., that could
pose a fire risk. If the entered safety controller temperature is exceeded. The heater is turned off at all
poles until manual reset (class 2).
The safety controller must be checked according to its function at appropriate intervals. Test: Set the
safety controller value below the temperature set-point. The chamber must not reach the temperature
set-point, but must turn off the heater when the safety controller value is reached.
Recommended setting: safety controller mode „Limit“.
Visual and additionally activatable audible (buzzer) signals indicate temperature exceeding.

Protection against touchable surfaces
Tested according to EN ISO 13732-1:2008.
