Before starting ensure the following conditions:
◊
The size of the power cables must be convenient to the maximum current that must pass
through them.

Enable Contact
This connection should be made only for humidifiers placed in centralized and ducted ventilation sys-
tems. It allows stopping the steam production each time the air ventilation in the channels stops. If pro-
duction is not stopped it would create a steam accumulation in the channels and a subsequent conden-
sation with water leaks.
To obtain this enable, you must bring a connection between the auxiliary contact of the fan contactor
(voltage free contact) to terminals J5-6 and J17-8 the humidifier electronic board.
If you do not use such enable, left the contact shorted (J5-6 and J17-8 terminals) as received from
Elsteam.

Draining block manual calibration
The drain block is calibrated in the best closed position during the testing phase. In case this position
were to vary with time (you see the high losses of the draining pipe), it should proceed to a new adjust-
ment of the closure of the draining block.
This procedure must be carried out with the full water kettle to allow the search of the optimal closed
position.
Please proceed as following:
1)
Switch the humidifier OFF
2)
Press and hold SET and OK simultaneously while providing voltage. The word "DISCHARGE SET-
TING" appears on the display.
3)
3) Press the + and - buttons to adjust the position of the drain block until you no longer see leaks
from the drain.
4)
Press OK.
Before any maintenance and installation power connection should be dis-
continued and protected against any accidental connection.
Before performing the electrical connections make sure that the voltage
available is equivalent to that of the humidifier.
