The valve of the gas cylinder
always must be closed before screwing on or unscrewing the gas hose
WARNING
Opening the cylinder valve when the cylinder is not connected.
Sudden release of the stored pressure energy.
Risk of injury.

Close the gas cylinder valve before connecting or removing the gas hose.
Secure the pressure cylinder against falling and other mechanical damage.
WARNING
Safety valve tearing off.
Sudden release of the stored pressure energy.
Risk of injury.

Secure gas cylinders against falling (chaining).
 Transport gas cylinders with a cylinder cart.
General information for safe handling of CO
2
pressure cylinders:
• Open the gas cylinder valve slowly to avoid pressure surges.
• Secure gas cylinders during storage and use against falling (chaining).
• Transport gas cylinders with a cylinder cart, do not carry, roll, or throw them.
• Always close the valve even with apparently empty cylinders; screw on the cap when not in
use. Return gas cylinders with the valve closed.
• Do not open gas cylinders by force. Mark them when damaged.
• Protect gas cylinders against fire, e.g. do not store together with flammable liquids.
• Observe relevant regulations for dealing with CO
2
pressure cylinders.
11.2 Operating the CO
2
emergency cooling system
When operating the CO
2
emergency cooling system, the freezer’s interior is flooded with CO
2
. CO
2
in
high concentrations (> 4 vol.-%) is hazardous to health. It is colorless and almost odorless and therefore
practically imperceptible. Operate the CO
2
emergency cooling system only in a well-ventilated room. Re-
leased CO
2
gas muss must be safely led out via good room ventilation or a suitable connection to an
exhaust system and through a conduct at the CO
2
discharge outlet (14) on the rear of the emergency
cooling system. Observe the occupational exposure limit for CO
2
set by the national authorities. We rec-
ommend installing a CO
2
warning system.
