Energy saving function
In ON mode, operating conditions permitting, the dryer reduces
energy consumption by temporarily switching off the refrigera-
tion compressor; the ENERGY SAVING LED (3) comes on (see
Control Panel).
Scheduled maintenance
[
Y
When the DISPLAY alternatively shows the Sr warn-
ing code and dew point, contact authorized assistance personnel
for carrying out scheduled maintenance indicated in par. 6.3 and
for resetting the warning code (see par. 5.4 in List of alarm/warn-
ings).
z
Press to cancel the warning for 24 hours.
Condensate drain
There are three operation modes:
a) INTEGRATED --- draining controlled by the level sensor;
b) TIMED --- check that the automatic condensate drainage sys-
tem 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 varies the amount of condensate to be removed.
For standard dryer operating conditions, see the following
table of recommended settings:
Model
PDRD265 ---1000
Parameter d1: time open in seconds for every 2 minutes of
operation.
c) EXTERNAL --- if there is an external drain
To change operation mode, use the parameter d3 (see par. 5.3 in
List of parameters)..
Y
Only set the EXTERNAL mode in absence of the solenoid
valve. Otherwise the relative coil could become damaged.
