Do not install or operate the CO
2
incubator C 150 in potentially explosive areas.
DANGER
Explosion hazard.
Danger of death.
∅
Do NOT operate the unit in potentially explosive areas.
∅
KEEP explosive dust or air-solvent mixtures AWAY from the vicinity of the unit.
CO
2
is harmful in high concentrations. Any gas that may escape has to be led out via good room ventila-
tion or by connection to a suitable exhaust system.
WARNING
High concentration of CO
2
.
Danger of poisoning.
∅
Do NOT set up units in non-ventilated recesses
¾
Ensure technical ventilation measures
¾
Observe the relevant regulations for handling CO
2
.
Check compliance with the
maximum permitted workplace concentration for CO
2
when operating all
units located in the room.
•
Maximum permitted workplace concentration (for Germany): 5000 ppm = 0.5 vol.-%
•
CO
2
lost with each door opening: about 16.4 g, i.e. 0.0084 cubic meters /
0.296 cubic feet
(under
normal pressure)
•
CO
2
lost during 12h at 5 vol.-% without door opening: approx. < 2 g, i.e. 0.001 cubic meters /
0.035
cubic feet
(under normal pressure 1013 mbar /
14.7 psi
)
An example of how to evaluate laboratory volume and air change rate:
Question:
Is an air change rate of 1/h sufficient for a lab with a volume of 100 cubic meters /
3,531.5
cubic feet
with 10 incubators C 150, opened 4 times per hour?
Calculation:
CO
2
concentration = CO
2
lost by door opening, multiplied by 10 units, multiplied by 4 door
openings per hour, divided by lab volume
0.0084 cubic meters x 10 x 4 div. 100 cubic meters = 0.00336, i.e. 0.336% or 3360 ppm.
0.296 cubic feet
x 10 x 4 div.
3,531.5 cubic feet
= 0.00336, i.e. 0.336% or 3360 ppm.
Result:
The maximum permissible value of 5000 ppm is not exceeded under these operation conditions.

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 unit.
Permitted shelf loads:
Maximum load on one single shelf:
10 kg /
22 lb
Maximum total load on all shelves:
30 kg /
66 lb
