3.7.17 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.

Safety devices
WARNING
The safety devices are aimed at protecting the operating personnel.
In case of safety devices that are not operating correctly or of safety-
relevant operating elements that are not freely accessible, there is a risk
of severe damage to health.
• Keep the safety-relevant operating elements freely accessible at all
times!
• Do not manipulate, remove, or disable the safety devices in any way!
• Check the correct operation of the safety devices at regular intervals in
accordance with the applicable national and international laws, rules,
and regulations concerning health and safety and the prevention of
accidents!
Main switch (line disconnector) and control switch
Position see chapter 2.1.1 - "Functional and operating elements"
The main switch is used to disconnect the freeze-dryer from the mains
power supply. As a result, all of the automatic valves will be closed and all
of the units will be switched off. A running process will be interrupted and
can be resumed at a later time.
In order to disconnect the control circuit from the power supply as well, the
control switch must also be switched off!
