3.7.16 Hazards caused by hot surfaces
WARNING
Risk of burns on hot surfaces
During the operation of the freeze-dryer and half an hour afterwards, the
outer surface of the freeze-dryer (especially the pipes and units) may be
hot.
There is a risk of burns when touching the surfaces.
• Wear suitable protective clothes and gloves!
• Do not touch the surfaces on purpose!
• Prior to performing any maintenance work on the vacuum pump or the
oil mist separator, let the components cool!
WARNING
Risk of burns on hot surfaces
After a drying process, some or all of the surfaces inside the chamber
(chamber walls, shelves, intermediate valve, etc.) may still be hot.
There is a risk of burns when touching the surfaces.
• Wear suitable protective clothes and gloves!
• Do not touch the surfaces on purpose!
• Prior to performing any work on the freeze-dryer, let the components
cool!
3.7.17 Hazards caused by cold surfaces
WARNING
Risk of freezing to cold surfaces
The shelves and ice condenser coils can already be cold during the
loading phase.
There is a risk of freezing to the shelves or ice condenser coils when
touching the surfaces.
• Wear suitable protective clothes and gloves!
• Do not touch the surfaces on purpose!
3.7.18 Hazards caused by overpressure in the chamber
DANGER
Risk of injury caused by bursting of the chamber
The double chamber is designed for vacuum. It is not a pressure vessel!
In the event of a malfunction, an impermissible excess pressure may build
up in the chamber, which may cause the chamber to burst.
This may lead to life-threatening injuries.
• Do not use the freeze-dryer when it is pressurised (excess pressure)!
• We strongly recommend installing a pressure relief device (e.g. a
safety valve or rupture disc) with a sufficient rating.
