Set-up and connection
WARNING
Risk of injury caused by poor accessibility of the freeze-dryer
In cramped spaces or locations with poor accessibility, sharp edges and
corners may protrude into the work area.
This may lead to injuries caused by impact hazards or grazing hazards.
• Ensure that the freeze-dryer is set up freely accessible!
• Comply with the fundamental health and safety rules and regulations
as well as with the rules and regulations for the prevention of
accidents!
WARNING
Risk of injury caused by escaping media or other consequences of
improper connections
Improper connections may lead to problems, e.g. a hazardous electrical
incident or the escape of media (depending on the configuration of the
freeze-dryer e.g. hot water, nitrogen, hydrogen peroxide), at a later time
during the operation of the freeze-dryer.
This may lead to severe damage to health or even life-threatening injuries.
• Ensure that the supply and disposal connections are established by
competent and specialised persons under consideration of the
corresponding connection specifications (see the instructions in this
chapter and chapter 10 - "Technical data")!
• The connections to the on-site pipes must be force-free and torque-
free!

5.1
Installation site
Operate the freeze-dryer only in closed and dry rooms.
NOTE
Refrigeration problems of the freeze-dryer are often caused by insufficient
conditions at the location of use. This is why compliance with the following
conditions is absolutely mandatory!
• Ensure sufficient ventilation. Do not place any paper, cloth, or similar
material behind or under the unit, since otherwise the air circulation will
be impaired.
• Keep a safety distance of at least 30 cm around the freeze-dryer so that
the vents in the unit remain fully effective.
• The ambient temperature must be in the range of +5°C to +25°C. A
potential night-time setback of the air conditioning system must be
taken into consideration.
• Prevent the room temperature from rising, for example due to closed
doors at night.
• Do not subject the freeze-dryer to thermal stress, e.g. by positioning it
near heat generators.
• Prevent thermal overload, e.g. caused by other equipment in the direct
vicinity of the freeze-dryer.
• Do not set up the vacuum pump directly next to the heat exchanger
(condenser).
• Avoid direct sunlight (UV radiation).
