C 150 (E2) 12/2012 page 23/90
Avoid direct solar radiation on the unit.
Permissible ambient humidity: 70% r.H. max., non-condensing.
Installation height: max. 2000 m / 6561.7 ft above sea level. After the incubator has been turned on for
the first time, enter the altitude of the site above sea level into the RP1 controller (chap. 8.1).
Wall distances: rear 100 mm / 3.94 in, sides 50 mm / 1.97 in.
Notes on handling carbon dioxide (CO
2
)
Carbon dioxide (CO
2
) in high concentrations is hazardous to health. It is colorless and almost odorless
and therefore practically imperceptible. Vent out any CO
2
gas that may escape via good room ventilation
or a suitable connection to an exhaust system. We recommend installing a CO
2
warning system.
WARNING
High concentration of CO
2
(> 4 Vol.-%).
Danger of death by suffocation.
Danger of poisoning.
Do NOT set up units in non-ventilated recesses.
 Ensure technical ventilation measures.
 Observe the relevant regulations for handling CO
2
.
Observe the occupational exposure limit OEL for CO
2
set by the national authorities (formerly maxi-
mum permitted workplace concentration). Check compliance when operating all units located in the room.
OEL for Germany: 5000 ml/m3 (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 nor-
mal 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.
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 unit.
Permitted shelf loads:
Maximum load on one single shelf: 10 kg / 22 lb
Maximum total load on all shelves: 30 kg / 66 lb
