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 ventila tion system off and secure it against unintentional power up LS 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 extend ed period This prevents the water from being sprayed directly into the duct in case the humidifier is powered up inadverte
