Start-up Checklist for STULZ UltraSonic® Humidifiers
The technical documentation of all units to be started up and their accessories is to hand
All humidifiers are precisely horizontal and securely mounted
Clearances and distances have been complied with
All units are accessible and operable
All humidifiers have an upstream actuation system
The oscillator PCBs are protected from voltage peaks by a TVS diode. This must be integrated
in the control system.
The electrical wiring is correct and complies with standards
Electrical power is available
Demineralized drinking water is connected to the supply pipe of all humidifiers
All water supply and drainage pipes and the overflow are correctly connected and secured
All accessories (e.g. water treatment system, sensors, fan, …) have been correctly fitted
All pipework channels and shut-off valves are known
Drinking water is available (if reverse osmosis or an ion exchanger is used, otherwise:
demineralized drinking water is available)
Duct units are locked with the airflow
The offtake capacity can be guaranteed by the upstream water softening equipment
The minimum pressure of 0.5 bar at the humidifiers is complied with
The maximum operating pressure of 6 bar at the humidifiers is not exceeded
The conductivity specified for the application is adhered to
Sensitive components are protected from or resistant to demineralized water
The humidifiers are protected from impurities that may arise (dust, pollen, etc.)
The flush valve is installed downstream from the humidifier in the drainage pipe, and is
below the humidifier
