USER MANUAL
FIRST IGNITION
1. Verify that the default setting is compatible with the signal connection made; if different,
configure the electronics correctly before powering up as described in chapter 2.
2.
Before connecting the humidifier, check the correct connection of the phases and of the type of
input signals; check also the correct connection of the mains water, the water drain and the
steam tube.
If the mains water connection line has been made with pipes that may contain oily residues
or other substances that generate foam, it is essential to wash it by letting the water run for a
few minutes.
3.
Check that there are no water leaks inside the humidifier.
4.
Give power supply to the humidifier.
5.
The humidifier will run a water drain for a few seconds, emitting a long beep.
6.
The humidifier is now in STAND-BY mode. To switch it on, press the ON/OFF – STAND-BY
key: the humidifier will display the humidity or temperature or current absorption value,
according to the set operating mode.
7.
The humidifier to work requires the digital input 1 to be enabled by means of a voltage free
contact (terminals 24 and 25 on the electronic board Master HUM2) regardless of the selected
operating mode and if the parameter In1 = ± 2. When not enabled, the display alternates the
word OFF to the normal display.
STEAM PRODUCTION
1.
Set the required humidity or temperature value by pressing the SET key and increasing
the value with the UP key, in the 4-20mA PROPORTIONAL models (if the set value is
higher than that measured by the probe, steam production begins); or give ON/OFF or 0-10V
consent in the ON/OFF or PROPORTIONAL 0-10V models.
2.
Allow the cylinder to fill up until the water starts boiling, then completely empty the cylinder
with the MANUAL DRAIN key to start the pump. Repeat the operation 1-2 times.
3.
Now the humidifier is operational and can function properly in a completely autonomous way.
