Item Work to be carried out
Nozzle system – Check the spray pattern of the spray nozzles (spray cone: optimum 90°, 60° acceptable). If necessary,
clean the spray nozzles (see full servicing guide).
– Check hoses and connections for sealing, if necessary, replace defective components.
Post evaporation unit – Check ceramic plates for breakage. Damaged plates should be replaced (see full servicing guide).
Note: A grey discoloration of the ceramic plates is normal. This is due to deposits from the silver ionization.

Periodical checking
Periodical checking should be carried out monthly and include the following
steps:
– Silver ionization: see detailed information in chapter 6.4.
– Check the hoses and connections on the booster pump, the silver ionization and the connection box for
sealing. Replace defective components where necessary.
– Check the water container and humidifier housing for soiling (Rust, slime, dust), clean if necessary (see
full servicing guide).
– Check the water container behind the post evaporation unit for collection of residual water. If residual
water is present, check the water drain and the post evaporation unit.
Maintenance record – Read off the operating parameters, including “Fault history”, on the display level and enter the values on
the maintenance record sheet.

Total hygiene service of the hybrid humidifier
The frequency of the implementation of a total hygiene service depends on
the operating conditions. The state of the humidifier‘s hygiene and its
components mostly depends on the quality of the humidifier water, the
performance (and the frequency of replacement) of the filter installed
before the unit, the air velocity, the air temperature, and the microbiological
and chemical composition of the inlet air.
The basic rule is: when the “Maintenance due” message appears, or
at least once a year, the implementation of a total hygiene service is
obligatory.
Resetting the “Maintenance due” message
Upon completion of the total hygiene service the “Maintenance due“
message may be reset as follows: Make sure the control unit is switched
off, then press and hold any key while switching the control unit on.
Keep the key depressed (approx. 5 seconds) until the red error LED lights
up briefly (approx. 1 second).
Nozzle system – Switch on the individual spray circuits manually and check the spray pattern of the spray nozzles
(spray cone: Optimum 90°, 60° permissible). Remove spray nozzles with a poor spray pattern (see Chapter
6.3.2) and clean them in an ultrasonic bath.
– Check hoses and connections for sealing, if necessary, replace defective components.
– Check spray nozzles for secure seating. Slightly tighten loose jets with open-end spanner (width 16 mm).
