CAUTION
Output pressure higher than the value indicated on the incubator.
Damage to the unit.
∅ Do NOT exceed the indicated output pressure of 2.5 bar / 36 psi above the ambient
pressure.
¾ Before connecting, check the output pressure on the pressure reducer of the bottle.
The CO
2
gas necessary for operation must have a technical grade of 99.5 %.
Connect the CO
2
bottle with the supplied gas hose. Socket DN 6 for a hose with internal diameter 6 mm /
0.24 inches. For connection to the quick acting closure socket (14) on the rear of the unit, see chap.
4.4.2.
Adjust the gas admission pressure at the CO
2
connection of the gas bottle to 2.0 bar / 29 psi
above the ambient pressure.
Replacing gas bottles: Remove the hose connection to the incubator. Then open the main valve of the
bottle pressure reducer. Check the output pressure on the second manometer; if appropriate, set it to 2.5
bar / 36 psi maximum. Only then should you establish a hose connection to the incubator.
The recovery times of the gas concentrations inside the chamber after opening the door are
indicated in the technical data (chap. 18.4) 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. 18.6.
If you connect several units with different maximum values of gas admission pressure to a
common supply net, use pressure reducers for units with a lower maximum gas admission
pressure.
4.4.2 Connecting the hose lead to the gas bottle
The gas hose, which will be used to establish the connection to a gas bottle, is already attached to the
hose nozzle and secured by a hose clamp. Plug the hose nozzle into the corresponding quick acting clo-
sure socket (a) located at the rear of the unit. 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 con-
nect the original hose nozzle. In this case, please contact BINDER Service.
