1.10 Foreseeable Misuse
Other applications than those described in chap. 1.8 are not approved.
This expressly includes the following misuses (the list is not exhaustive), which pose risks despite the
inherently safe construction and existing technical safety equipment:
• Non-observance of the Operating Manual
• Non-observance of information and warnings on the chamber (e.g. controller messages, safety identifi-
ers, warning signals)
• Installation, startup, operation, maintenance and repair by untrained, insufficiently qualified, or unau-
thorized personnel
• Missed or delayed maintenance and testing
• Non-observance of traces of wear and tear
• Operating the equipment without ESD protective equipment (e.g., clothing, gloves, shoes)
• Setting down the material to be loaded in the area around or on top of the chamber
• Occurrence of an impermissible zone outside specified areas (see Chap. 3.5)
• Improper termination of the drying process after incorrect loading with inadmissible solvent with too low
an ignition temperature: Ventilating or opening the chamber without waiting for it to cool
• Passing on passwords for the admin level to users
• Emptying the condensate catchpot of the pump without having prior turned off the vacuum pump
• Insertion of materials, which are excluded or not permitted by this Operating Manual and/or are not
permissible according to the Labeling on the type plate.
• Non-compliance with the admissible parameters for processing the respective material.
• Installation, testing, service or repair in the presence of solvents
• Material to be loaded remaining in the chamber after turning off.
• Loading non-approved solvents
• Incomplete ground connections for all system parts in the installation area
• Introduction of rust into the device
• Installation of replacement parts and use of accessories and operating resources not specified and au-
thorized by the manufacturer
• Structural changes to the chamber without a subsequent risk assessment by the operator's ATEX rep-
resentative
• Failure to observe the inspection and maintenance regulations (inspection before initial commissioning,
recurring tests, inspection after maintenance or repairs, qualification of the tester)
• Commissioning after maintenance or repairs without passing the electrical safety test
• Commissioning after maintenance or repairs without passing the explosion protection test.
• Commissioning without correctly and completely grounding in accordance with the grounding plan
• Non-observance of traces of wear and tear, in particular rust
• Installation, startup, operation, maintenance or repair of the chamber in absence of a risk assessment
and operating instructions from the operator
• Deliberate or careless handling of the chamber during operation (except the permitted operation of the
controller).
