5.1
Location of use
Use the freeze-dryer solely in closed and dry spaces.
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!
• The table must be stable and have a solid, even tabletop
• 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 in the area of the heat exchanger
ventilation grid (see chapter 2.1.1 - "Functional and operating
elements").
• Avoid direct sunlight (UV radiation).
