Installation
On installations preferably choose pressurized cylinders rather then gas wall
outlets. The use of cylinders will limit the amount of gas being spilled in case of
fatal failure. Whenever a wall outlet installation is chosen, make sure that there is
a remote shut off valve installed outside the room where the gas is used.
Place the cylinder in an easily accessible and visible place next to the incubator.
Remember that the cylinder will have to be replaced routinely. As the operator
will have to check the cylinder routinely it should be clearly visible to all personnel
during routine work.
Install the instrument in a room with a glass door or a window that will allow a
good view of the instrument and gas connection from outside the room. Often
major defects can easily be detected by visible vapor clouds or icy tubes without
the risk of entering a contaminated room.
Before installation make sure that the maximum specified inlet pressure is never
exceeded. Always install a main shut-off valve that will cut gas flow as close to
the source as possible. Secure cylinder when in use.
WARNING!
Gas cylinders are under extremely high pressure that must be reduced for
use with a StoreX incubator
Use a pressure-reducing regulator when connecting to lower pressure piping
system
Never exceed maximum specified inlet pressure
Never connect StoreX gassing inlet directly to a pressurized cylinder or wall
outlet
Use a two stage pressure regulator with indicating valves. The high pressure
gauge should have an indicating range of 0 to ~200 atm (0..3000 psi) to monitor
the pressure or the gas source. For CO2 a scale of 0..100 atm (0..2000psi) is
sufficient. The low pressure gauge should have an indicating range of 0..4 bar
(0..60 psi) and will monitor the input pressure to the StoreX. A flow meter is
recommend since it will show correct operation of the system.
