Foreseeable Misuse - Binder VDL Series Operating Manual

Personnel Requirements
Only trained personnel with knowledge of explosion protection and knowledge of the Operating Manual
can set up and install the chamber, start it up, operate, clean, and take it out of operation. Service and
repairs call for further technical requirements (e.g. electrical know-how), as well as knowledge of the ser-
vice manual. Follow the requirements for PPE (ESD protection) .
Installation site requirements
The chambers are designed for setting up inside a building (indoor use).
Provide active extraction (technical ventilation according to country-specific regulations – TRBS 2152
Part 2 for Germany). It must cover the entire installation area of the VDL and the vacuum pump stand. In
addition, the suction system behind the VDL must be provided on the floor. Suction must be active at
least during loading and unloading of the material to be dried and when handling the condensate catchpot
of the pump. Suction must be conducted into an explosion-proof area.
If the technical ventilation fails, automatically switch off power to the device.
VDL vacuum drying chambers are not intended for installation in a Zone 0 or 1. Measures must be taken
to prevent the spread of explosive atmospheres to unprotected areas. It must be possible to turn off the
device immediately in the event of a fault: Pull the power plug or operate the customer's explosion-
protected emergency stop switch.
The requirements described in the Operating Manual for installation site and ambient conditions (Chap. 5)
must be met.
In case of foreseeable use of the chamber there is no risk for the user through the integration of the
chamber into systems or by special environmental or operating conditions in the sense of EN 61010-
1:2010. For this, the intended use of the chamber and all its connections must be observed.

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 identi-
fiers, warning signals)
• Installation, startup, operation, maintenance and repair by untrained, insufficiently qualified, or un-
authorized 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. 3.6)
• 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 disconnected the vacuum drying
oven from the power supply
• 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.
