If a fault is detected during the system test, a corresponding error alert
is­triggered,­i.e.­the­error­indicator­either­flashes­(alarm)­or­stays­on­
(error), and a corresponding message appears on the display (also
see chapter 7.1).
After successful conclusion of the system test , the unit switches to
standby mode and one of the following displays appears, depending
on the current state of operation:
–­ The­Condair­Dual­is­in­standby­mode­(no­humidification).
–­ The­ Condair­ Dual­ humidifies­ (in­ addition,­ the­ “Humidification­ on”­
indicator lights).
– Drain valve open, the permeate is led directly to the drain conduit
(cause:­preset­flushing­cycle­is­in­progress­(every­24­hrs.)­or­the­
conductance of the permeate is too high).
If­the­external­ safety circuit ­(maximum­humidistat,­flow­control,­etc.)­is­
interrupted,­the­opposite­message­appears­and­the­“Error”­and­“Humidifi -
cation­on”­indicators­light­up­intermittently.
If a fault is detected during operation, a corresponding error alert is trigger-
ed,­i.e.­the­error­indicator­either­flashes­(alarm)­or­stays­on­(error),­and­a­
corresponding message appears on the display (also see chapter 7.1).
If maintenance is due or the silver ionization electrodes require replace-
ment , the corresponding message and the current status display appear
intermittently.
– Maintenance due
– Silver ionization electrodes worn
Please consult chapter 6 for further information.
Notes on operation
– Make sure the
minimum working pressure never drops below 2 bar
during operation. In case the working pressure drops below the limit,
check the reverse osmosis system and the fully demineralized water
supply.
– In standby mode the drain valve is opened for approximately 65 sec-
onds every 24 hours ­thus­flushing­the­permeate­supply­conduit­(for­
