Excessive outlet pressure > 2.5 bar / 36 psi.
Damage to the chamber.
∅ The outlet pressure must NOT exceed the indicated value of 2.5 bar / 36 psi.
Before connecting, check the outlet pressure on the pressure reducer of the
cylinder.
Adjust the outlet pressure to 2.0 bar / 29 psi above the ambient pressure.
Observe the correct outlet pressure also when replacing the gas cylinders.
Establishing the connection to the chamber
Connect the supplied gas hose (internal diameter 6 mm / 0.24 inches) to the pressure reducer of the
gas cylinders or central gas supply and secure the connection with the supplied hose clamp.
Connect the pre-assembled hose nozzle of the gas hose to the quick acting closure socket (9) DN 6
on the chamber rear, as described in chap. 4.4.4.
Leak test
After connecting the gas cylinder, check all gas connections for leaks (e.g. with leak spray or diluted
soap solution).
The recovery times of the gas concentrations inside the chamber after opening the door are
indicated in the technical data (chap. 25.4) and refer to a connection pressure of 2.0 bar / 29
psi. Decreasing supply pressure will result in longer recovery times.
Conversion table for gas inlet pressures, bar – psi, see chap. 25.8.
4.4.4 Connecting the gas hose to the chamber rear (for CO
2
, O
2
, N
2
)
The procedure of connecting the gas hose to the chamber rear is the same for any gas connection. All
quick acting closure sockets (CO
2
, N
2
with O
2
control, and O
2
with O
2
control and optional alternative
control range 10 up to 95 vol.-% O
2
) are degreased and supplied with a FKM gasket.
Note for chambers with O
2
control: The quick acting closure socket and the hose nozzle for the O
2
connection must be degreased.
WARNING
Fire and explosion hazard through contact of fat with O
2
.
Risk of burns and other injuries.
∅ All connection parts for the O
2
connection must be degreased.
The gas hose, which will be used to establish the connection to a gas cylinder, is already attached to the
hose nozzle and secured by a hose clamp. Plug the hose nozzle into the corresponding quick acting
closure socket (a) located at the rear of the chamber. This quick acting closure socket is closed by a
rubber cover (b).
Only use the supplied hose nozzle to connect to the quick acting closure socket.
Otherwise, the quick acting closure socket may leak, and/or it may become impossible to
connect the original hose nozzle. In this case, please contact BINDER Service.
