8.1.2
Ice condenser chamber
WARNING
Risk of poisoning/infection caused by contaminated condensate
(defrosting water)
The condensate may contain harmful substances originating from the
product.
Contact with the condensate may cause severe damage to health.
• Wear suitable protective clothes, gloves, and respiratory protection
when maintaining the drain system (especially when cleaning the
valves and when replacing the seals)!
Before each start-up, ensure that the ice condenser chamber is free from
water residues.
• Open the media drain valve to drain off any liquid. Then, close the
valve.
• If necessary, wipe the ice condenser chamber dry with a cloth.

8.1.3
Drying chamber
In order to avoid corrosion and negative effects on a subsequent freeze-
dryer process, it must be ensured that there is no water left inside the
drying chamber after every freeze-drying process.
• If necessary, wipe the chamber dry with a cloth.
8.1.3.1
Lamination of the loading door with a special film
Freeze-dryers with an acrylic glass door are equipped with the special
Radiation Shield film on the exterior side of the acrylic glass door (see
chapter 6.5 - "Loading door").
NOTE
For technical reasons, inclusions are possible. However, they do not
prevent the film from performing its function.
NOTE
In the case of acrylic glass doors with a Radiation Shield film, visible light
reflexions are possible. This is not a defect but rather the natural
consequence of the high-performance film.
To prevent the film from being damaged, compliance with the following
points is mandatory for cleaning:
•
In case of a contamination with toxic, radioactive or pathogenic
substances, clean immediately with a suitable decontamination agent
(see chapter 8.2 - "Disinfection of the drying chamber and
accessories").
• Clean with plenty of water immediately after use to ensure that
contaminants are flushed off and not wiped off.
