The following steps are required:
Ensuring the correct CO

output pressure
A gas supply pressure above 2.5 bar / 36 psi will result in unit damage.
Use a pressure reducer and make sure to avoid any excessive outlet pressure when connecting the
gas hose to the incubator.
The real outlet pressure of gas cylinders, sets of gas cylinders or central gas supplies am on the sec-
ond manometer must not exceed 2.5 bar / 36 psi.
CAUTION
Excessive outlet pressure > 2.5 bar / 36 psi.
Damage to the unit.
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 cylin-
der.
 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 incubator
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 (14) DN 6
on the unit rear, as described in chap. 4.4.2.
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. 19.4) 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. 19.6.
