Airflows
20
The unit offers the possibility to swap the directions of the airflows so that there are two
operating modes:
•
Mode A
•
Mode B
The inputs and outputs of the airflows in the two operating modes are depicted in the follow-
ing figures:
By default, the ducts on the side and bottom of the unit are closed but can be opened and
used as shown below. When opening the ducts on the side or on the bottom, the correspon-
ding ducts that are not used are usually closed. If required, two corresponding ducts can be
used simultaneously.
The standard operating mode is mode A.
