control: Notes on handling nitrogen (N
2
)
Nitrogen (N
2
) in high concentrations is hazardous to health. It is colorless and almost odorless and
therefore practically imperceptible. Any N
2
gas that may escape must be safely led out via good room
ventilation or a suitable connection to an exhaust system.
WARNING
High concentration of N

.
Risk of death by suffocation.
∅
Do NOT set up chambers in non-ventilated recesses.

Ensure technical ventilation measures.

4. Installation and connections
4.1 Shelves
You can put the shelves in different positions at the line of channel beads in the inner chamber. Hold the
shelf straight and then insert it so it will go smoothly inside the chamber.
Permitted shelf loads:
Maximum load of one single shelf: 10 kg / 22 lb
Maximum total load of all shelves: 30 kg / 66 lb
4.2 Permadry™ water pan
The Permadry™ system developed by BINDER is an effective and easy to handle system that ensures
high humidity inside the chamber without any condensation forming on the inner surfaces. The
Permadry™ water pan consists of two pans in which the outer one is heated and the inner one cooled.
With the slight difference of temperature caused by that cooling, the central pan is the specific point for
condensation of the surplus humidity. Therefore, all other inner surfaces remain dry.
