NOTE: the values of Tab. 4 are indicative. By default the dip switches are set for Max capacity.

5.2 Adjusting the humidification capacity

Adjustment can be done during the installation phase, or later if, for example, machine operation is to be adapted to the variations of the
environmental conditions in the environment where it has been installed. In this case, proceed as follows:
•
Perform the stopping procedure as in par. 4.3;
•
remove the air filter by unscrewing the three screws that hold it;
•
remove the electrical connection box by releasing the spring;
•
open the electric connection box and adjust the position of the potentiometer or the dip switches according to its needs;
•
close the machine as described in par. 3.8
Start the humidifier again.

5.3 The washing/reset cycle

The electronic card of the NEB 6500 is programmed to carry out a washing/reset cycle each time: the machine is started with the main switch;
•
the humidistat switches off the machine because the necessary R.H. conditions have been reached.
The scope of this cycle is to prevent water depositing in the machine when it is not in operation, in this way preventing the proliferation of
bacteria.
The cycle has a fixed duration, and consists in:
•
Exclusion of the motor, and a 40-second waiting period
This waiting period gives the motor (and thus the fan/disk unit) the opportunity to stop completely, and give the water in
the machine time to collect at the bottom of the basin.
•
Enabling the water loading solenoid valve
The water enters the basin until the level sensor trips.
•
Wait for the level sensor to close
When the level sensor contact closes it enables a timer inside the card.
•
Keeping the water loading solenoid valve enabled for 10" after the level sensor has tripped
In this way the water level in the basin exceeds that of normal operation and the siphon is primed and this drains the water
in the basin.
•
Disabling the loading solenoid valve.
•
Waiting for a fixed time of 10"
This time period is needed to make sure that all the water in the basin is drained off.
•
End of the reset cycle
At the end of the reset cycle the machine waits for the humidistat contact to be closed or, if it is already closed, starts the machine and begins
to humidify.
