Aggressive condensate is possible. Wear protective glasses and
proper protective clothing!

release the fastening screws from the flow components sub panel;

pull out half the sub panel and lower so that the backside tube connections are accessible;
N O T E !
The flow components sub panel is not rail mounted!

release the tube connections at the top of the flow meters FM1 and FM2;
 disconnect the tube ‘flow chamber/heat exchanger’ on the side of the chamber;

pull out the hoses of the condensate pump through the guides in the sub panel;

pull out the plug in connection from the connector block X8 (see fig.3).
Now the sub panel can be completely taken out of the 19“ housing.
Mounting the sub panel happens in opposite order. Please pay attention to the following instructions:

mounting the plug in connection look out for the sequence of numbers;

after the implementation of the condensate hoses pay attention of possible folds;

tighten the union nut of the liquid alarm sensor by hand;

21 ALARMS AND ELIMINATION
The alarms are displayed on the operation and control board (see fig.2) by LED’s. The alarms are
available as a status contact in the Sub-D-Plug (s. 10.2.2 u. 10.2.3).
21.1 VOLTAGE LOSS
At a voltage loss the operation and control board of the CSS
is out of function and the LED’s are ex-
tinguished (see 8.). A signal is available at the alarm status contact in the Sub-D-Plug (s. 10.2.1).
Carry out the following controlling steps:

check the position of the main switch;

check the external fuse; if necessary exchange the fuse;

check the fine fuse (F1=2A, see circuit diagram in the appendix) on the main board of the CSS; if
necessary exchange the fuse.
