Condensate drain
There are three operation modes:
a) INTEGRATED - draining controlled by the level sensor;
b) TIMED - check that the automatic condensate drainage system is
working properly.
Use manual drainage to check that condensate is not retained as this
is symptomatic of poor drainage.
This check of the timed drain opening (parameter d1).
Settings depends upon the operating conditions of the dryer and var-
ies the amount of condensate to be removed.
For standard dryer operating conditions, see the following table of
recommended settings:
Model

Parameter d1: time open in seconds for every 2 minutes of opera-
tion.
c) EXTERNAL - if there is an external drain.
To change operation mode, use the parameter d3 (see par. 5.3 in List
of parameters).

Otherwise the relative coil could become damaged.
