3.4.2
Ventilation Opening
An opening for ventilation of the interior is located in the top centre
of the rear of the casing. The purpose of ventilation is to supply bac-
terial cultures with oxygen from the air.
The opening with a diameter of 22 mm is covered by a metal plate
with plug and O-Ring. The metal plate can be mounted in two differ-
ent ways:
If the plug (1) is directed inwards and the bevelled parts of the
plate (2) point outwards, the plate seals the opening.
In contrast, if the plate is mounted in such a way that the bev-
elled parts face the device, this results in a ventilation slot.
INFORMATION
The device is always delivered with the ventilation opening open. If
a significantly higher gas consumption is detected when using the
CO
2
option, the ventilation opening can be closed if necessary.
Please note that closing the ventilation opening can lead to a lack
of oxygen in the culture and therefore to low growth.
3.4.3
Air Vents
The device has air vents on the right-hand side and the rear of the
casing. When setting up the device, you must ensure that these air
vents remain unobstructed (keeping a minimum distance of 80 mm
to walls or objects on either side) in order to ensure that the exhaust
air can be extracted without obstruction and none of the compo-
nents overheat.
