The recovery times of the gas concentrations inside the chamber after opening the door are
indicated in the technical data (chap. 22.4) 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. 22.8.
4.3.2 Connection of the O
2
gas cylinder (unit with O
2
control)
Note: Do not connect the O
2
cylinder or disconnect the gas supply (by pulling off the gas hose)
when operating at setpoints below 19 vol.-% O
2
.
Oxygen (O
2
) is colorless and almost odorless and therefore practically imperceptible. It promotes burns,
which can proceed explosively. There is a fire hazard for flammable oxygenated materials, e.g. clothes
and hair. O
2
is heavier than air and may accumulate in low-lying areas.
WARNUNG
High concentration of O
2
(> 21 % O
2
).
Fire and explosion hazard through contact of combustible materials with O
2
.
Risk of burns and other injuries.
∅
Do NOT set up units in non-ventilated recesses.
 Ensure technical ventilation measures.
 Observe the relevant regulations for handling O
2
.
The O
2
gas necessary for operation must have a technical grade of 99.5 %.
The gas connections must be established by qualified personnel who are trained in handling
the respective gases and familiar with the required safety measures.
The following steps are required:
Ensuring the correct O
2
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
second 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
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.
