5.3 Taking the humidifier out of operation
To take the Condair Dual Hybrid Humidifier out of operation, e.g. for maintenance
purposes, proceed as follows:
• Set the power switch to “O”.
• Disconnect the control unit from the mains: Set the service switch
of the mains supply line to “Off”.
• Close the shut-off valve of the water supply conduit.
Note: If the water supply system requires maintenance depressurize
the water system first. For this purpose switch the control unit back on
again and wait until flushing is concluded and the alarm message
no. 07 “minimum permeate pressure” appears on the display. Then,
switch the control unit off again, as described above.
• Mind hygiene! Let the fan of the ventilation system run until the
humidification unit is dry.
• In case the humidification unit requires maintenance switch the ventilation
system off and secure it against unintentional power-up.
Important information on extended periods of non-use
Important! For reasons of hygiene, we basically recommend that the
Hybrid Humidifier should be left switched on, even in periods when there
is no requirement for humidification. With the system switched on, the water
circuit is flushed at regular intervals and hence the build-up of germs is
opposed.
However, if it is necessary to leave the Hybrid Humidifier switched off for
long periods, the following points should be noted:
– Mind hygiene! Drain all water conduits.
– For safety reasons the post-evaporation elements should remain in
their working position, even if the humidifier is not used for an extended
period. This prevents the water from being sprayed directly into the
duct in case the humidifier is powered up inadvertently.
