3. Installation of the device
3.1 Ambient conditions
The device must only be operated at 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 3.3.).
• The operating room must be equipped with an appropriate room ventilation.
• Solid, level, fire-proof surface.
• Vibration-proof substructure (floor stand, lab table) capable of bearing the
weight of the device and of accessories (particularly if several devices are
stacked).
• To ensure a constant incubation temperature of 37° C, the ambient tempe-
rature must be within a range of +18° C to +33° C.
• Relative humidity up to 80 % (max.).
• No direct exposure to sunlight.
• Devices that produce excessive heat are not allowed near the location of the
HERAcell
®
150.
3.2 Room ventilation
When CO

is supplied, the work space of the incubator is slightly pres-
surized. 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 CO

into 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.
• Therefore, the HERAcell
®
150 must only be installed in rooms with sufficient
ventilation.
• Do not install the device in room recesses without ventilation.
• The room ventilation should be a technical ventilation that is in accordance
with the requirements of ZH 1/119 (Guidelines for laboritories) or some other
suited ventilation system with appropriate capacity.
