Fresh water pressure
The float valve is approved up to a max. operating pressure of 6 bar.
robatherm recommends fresh water pressure of at least 3 bar; if necessary, install a pressure booster
system.
Cleaning before filling
Clean the humidifier tray of foreign bodies, clean contaminants with water and a cleaning agent (non-
foaming, pH value 7 - 9).
Remove metal chips thoroughly, otherwise there is a risk of pitting.
Tightness
Check external lines for tightness and re-seal if necessary.
Filling
Fill the humidifier tray to 10 to 20 mm below the overflow connection and adjust the float valve to this
water level by adjusting the knurled screw.
Only fill the humidifier tray with fresh water when humidification is required.
Treated water must be removed from galvanized parts immediately. There is a risk of white rust
formation.
Disinfection
UV-C lamps (with self-monitoring UV-C selective sensors) may be suitable for continuous disinfection.
Only use chemical disinfectants (biocides) if they have been proven to be safe in the respective
application concentration.
Connection to the fresh water system
When connecting to the fresh water system, provide a pipe disconnector on site in accordance with
EN 1717.
Connection of the drain and overflow lines on the circulating water spray
humidifier (low pressure)
Connect the drain line of the circulating water spray humidifier (low pressure) and the
pan drain of the pre-assembled pan separately to the waste water system. Do not
empty the humidifier pan into the pre-assembled pan.
