System Description
Water Reservoir, Fig. 11:
The water reservoir [1] is integrated into the base of
the inner chamber and slopes towards the rear unit
wall. Bulges in the base of the pan serve as indicators
for the maximum fill level [3] and minimum fill level [2].
Rack System:
The support profiles for the rack systems have perfo-
rations every 42 mm. This allows the support brackets
to be inserted in locations to accommodate any cultu-
re vessel size. The insert trays have integrated tip-
protection and a stop to limit pull-out distance. Refer
to Chapter 6, "Commissioning", for a detailed descrip-
tion of the rack system.
Rear Unit Wall Openings, Fig. 12:
A pressure compensation opening [2] on the unit's re-
ar wall equalizes the pressure between the sample
chamber and the ambient environment.
An access port [1] which can be sealed when not in
use allows lines, tubes, or additional sensors to be
added to the unit's sample chamber.
NOTE –Operating conditions:
When auxiliary units are operated in the CO
incubator's sample chamber, the requirements of the
ambient conditions must be observed (refer to the ta-
ble). Energy brought into the sample chamber will in-
fluence the start of the temperature regulation range.
The inclusion of additional heat sources in the sample
chamber can result in the formation of condensation
(e.g., on the glass door).
