The required disposal lines for emitting steam and condensate must be laid with a
gradient towards the drain. A minimum diameter of 10 mm is necessary; the lines
must not exceed a length of 2 m. The lines must be free of kinks and crushes. It
should also not be laid in tight bends. The line outlets have to be free. They are to
be mounted fixedly to the drain (Figure 16). The lines should be equipped with a
vacuum breaker and swing type check valve each, otherwise waste water may be
sucked back into the container by negative pressure.
Produced condensate: approximately 0.5 to 1 litres per batch.

Condensate collector
The condensate collector is a simple device for collecting the condensate emitted
from the sterilizer at a favourable price. It is used for liquefying spent steam and
cooling exhaust air. In this case, an on-site disposal line is not necessary. Even in
safety laboratories, the condensate collector can be used to good advantage as
the on-site disposal system will remain uncontaminated.
Plastic container made of temperature-resistant PEHD, rectangular, with two
handles.
Dimensions (L x W x H): 275 x 235 x 405 mm
20 litres volume.
Large cleaning hole (Ø 140 mm) with screw lid and stainless-steel immersion tube,
quick-release coupling for hose connection.
Steam disposal hose, R ½", male thread and quick-release coupling, 1 m long,
blue.
INFORMATION
Only use the condensate collector, if you just utilize the
sterilizer occasionally. When the collector overflows, water
damage may arise.
Especially in case of contaminated exhaust air, the water in the
collector as well as the collector itself may be infected with
germs. This factor is to be considered when disposing of the
collector content.
♦ Fill the container with approximately 5-6 litres tap water.
♦ Connect the temperature-resistant steam disposal hose to the quick-
release coupling.
