• The corresponding interface is provided on the side of the electric cabinet on the back of the
incubator. There is hose supplied with the incubator. The gas entering the incubator must fi rst pass
through the pressure reducing valve to reduce the output pressure to 1.0 Bar ± 0.2 Bar. The pressure
reducing valve needs to be provided by user.
• From the perspective of technical safety, the output pressure may vary within the range of 1.0 Bar ±
0.2 Bar.
The pressure reducing valve is not a standard accessory for the incubator. Users may
