Make sure that the water pan has firm contact with the inner chamber bottom and rests tightly on it.
Fill the water pan with 1 liter of distilled, sterilized water.
We recommend cleaning (chap. 22.1) and refilling the pans 2 to 3 times a week. For evacuation, remove
the water pan.
We recommend using distilled, sterile water to achieve optimum growth results. Any corrosive damage
that may arise following use of water of different quality or by additives is excluded from the liability
agreement.
If required, you can add microbiologically inhibiting substances such as copper chips, copper sulphate or
ethylene diamine tetra-vinegar acid (EDTA) in a concentration of
1 to 5 mmol/l.
Empty the water pan before moving the incubator. In case of the contents spilling, immediately shut down
the incubator and dry it carefully and completely.
4.4 Gas connection
General information for safe handling of gas cylinders:
• Store and use gas cylinders only in well ventilated areas.
• 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 gas cylinders.
Secure the gas cylinders against falling and other mechanical damage.
WARNING
Risk of injury through sudden release of the stored pressure energy when the valve
safety is torn off.
Injuries.
Secure gas cylinders against falling (chaining).
Transport gas cylinders with a cylinder cart.
The valve of the gas cylinder always must be closed before screwing on or unscrewing the gas hose.
WARNING
Risk of injury through sudden release of the stored pressure energy when opening
the cylinder valve of a not connected cylinder.
Injuries.
Close the gas cylinder valve before connecting or removing the gas hose.
After connecting the gas cylinder, check all gas connections for leaks (e.g. with leak spray or
diluted soap solution).
