Installation of the device
Ambient conditions
The device must only be operated in locations that meet the particular ambient conditions listed
below.
Requirements:
Draft-free and dry location.
The minimal distance to adjacent surfaces must be observed on all sides (see Section
“Space requirements”).
The operating room must be equipped with appropriate room ventilation.
Solid, level, fire-proof surface.
Vibration-proof substructure (floor stand, lab table) capable of bearing the weight of the
device and accessories (particularly if several devices are stacked).
To ensure a constant incubation temperature of 37 °C, the ambient temperature must be
within a range of +18 °C to +33 °C.
Relative humidity up to 80% (max.).
Avoid direct exposure to sunlight.
Devices that produce excessive heat should not be used near the location of the CO2
incubator.
Room ventilation
When CO2is supplied, the work space of the incubator is slightly pressurized. The pressure is
released through the pressure compensation opening into the operating room.
As the pressure compensation and any opening of the glass door/gas tight screen during the
operation of the device will release very small quantities of CO2into the operating room, the room
ventilation must be capable of carrying the released gas safely off into the open.
In addition, heat dissipating from the device during permanent operation may cause a change in
the room climate.

| Installation of the device
