Design and Function
2.6.2 Connection of external appliances
Only appliances may be connected to external connections whose interfaces comply with the
requirements for safety extra-low voltage (e.g. computer).
2.6.3 Gas connection (only for models with CO
2
supply)
The appliance can be connected with the supplied compressed air tube via a pressure regula-
tor with gas bottle monitor (DIN 8546) to a CO
2
compressed gas bottle or directly to a central
CO
2
gas supply.
The primary pressure must not exceed 1.2 bar. A value between 0.8 and 1 bar is considered to
be an ideal value.
2.6.4 Water connection
The supplied tube can be used to connect the cooled incubator with the supplied water tank.
2.7 Intended use
ICH cooled incubators may only be used for incubating cell cultures, for material and stability
tests or similar. Any other use is improper, and may result in hazards and damage.
Cooled incubators are not explosion-proof (they do not comply with the German workplace
health & safety regulation VBG 24). The appliances may only be loaded with materials and
substances which cannot produce any toxic or explosive vapours at temperature ranges up to
60 ºC and which cannot explode, burst or ignite.
The incubators may not be used for drying, vaporising and branding paints or similar materi-
als the solvents of which could form an explosive mixture when combined with air. If there
is any doubt as to the composition of materials, they must not be loaded into the cooled
incubator. Potentially explosive gas-air mixtures must not be produced, neither in the interior
of the chamber nor in the direct vicinity of the appliance.
Only CO
2
gas bottles with a pressure regulator may be connected to the gas connection of the
appliance. The use of other gases or materials than CO
2
is not permitted.
