3 Operating instructions
3.1 Precautionary measures
Follow the safety guidelines relating to your field of
application, especially those for preventing biological
hazards caused by infectious media. When handling
corrosive substances you can also damage equipment in
the surrounding area.
Avoid blocking the fan heater of the device! This may
lead to overheating. In the case of a blockade,
immediately disconnect the device from the power
supply. Inform the service personnel of Sartorius AG.
3.2 Startup
3.2.1 Preparing the incubation hood Installing the
incubating devices or containers
1. In standard changes wait until the device is in room
temperature before operating it. When the incubation
units are very cold, moisture can build up inside the
device and cause faulty operation.
2. Place the shaker or the device with the media or
container to be heated in the incubation chamber of the
CERTOMAT ® H/HK.
If you use a CERTOMAT ® HK and you would like to
3.
lower temperature to below room temperature, connect
your coolant supply system or an external cooling unit
to the tube clips of the incubation unit and bleed the
system.

If you wish to change the target value, enter the new
value by pressing the "+/-" keys:
- Press the "+" key to obtain a higher target value
(Fig. 11, pos. 1)
- Press the "-" key to obtain a lower target value
(Fig. 11, pos. 3)
2. The longer you press the respective key, the quicker the
value in the display changes.
•
The temperatures cannot be set outside the target value
range of +10 ... +60 °C
•
The heat indicator now shows the current value in the
incubation chamber. You can regulate the target value
at any time by pressing the "+/-" keys (Fig. 11, pos. 1
and 3).
3. If necessary, you can increase the ambient air supply by
