4 Working principle
The ultrasonic humidifier is an adiabatic humidifier based on the water atomization
generated with the vibration of a piezoelectric membrane.
The ultrasonic humidifier causes the evaporation of water by generating microscopic water
drops negatively ionized. Thanks to the negative ions, the air is purified by precipitation of
the pollutants in suspension. These humidifiers are particularly quiet.
The humidifier consists of a case, an electronic control board, a draining system, a tank, a
fan with speed control and a level detector.
The microcontroller based control system performs a cleaning of the water tank at the
switch ON and every 6 operating hours.

6 Installation
The humidifier must be installed in a room ventilated and protected, on a vertical surface,
plane and rigid. Use the two eyelets of the case and check that the tank is in horizontal
position. For multiples units (UH206...UH406) please use at least one eyelet for each unit,
to fix humidifier, to prevent lateral forces that may cause breakage of the tank.
The mains transformer can be installed remotely.

6.2 Hydraulic connections
Hydraulic connection to the units must be realized with flexible pipes which do not cause
an action on the tank to avoid damaging the unit.
The hydraulic connections are positioned on the bottom side of the humidifier. Input
connection is 3/4" and output is 1/4”.
The minimal pressure at the entry of the pump should be lower than 0.5 at maximum flow.
6.3 Steam Output
The steam output is positioned in the upper part of the humidifier (top cover). The outlet
has a diameter of 40mm. To avoid the release of micro-droplets of water by the output
should be installed a distribution ramp of 40 cm minimum. The ramp can be made of PVC or
other material (as required by the application). In case you can not install a ramp of 40 cm
at the exit you can install a double stitched at 90° to create a trap for micro-drops.
6.4 Electrical connections
The person in charge of installation will have to ensure the following points :
Size of electrical cables must be appropriate for the maximum current being
provided.
The power supply cable will have to be protected using an appropriate cable gland.
All work concerning electrical installations WILL HAVE to be carried
out exclusively by qualified personnel (ex electricians or technicians
laying ou
t from a suitable formation). The customer IS responsible for
the adequacy of the personnel used.
Please check that power supply is disconnected before any
maintenance and installation operation.

Each connection of terminal will have to be firmly protected by a fixing of cable.
The electric terminals are positioned inside the apparatus (remove the screws which block
the lower panel of the case to reach them).
In case the mains transformer is not delivered already connected to the humidifier, please
use table below to connect.
Figure 1 shows positioning of electrical terminals on the electronic board.
Before the beginning of installation (and all operations o
f
maintenance and maintenance without panel) the power supply
must be disconnected on all the lines and insured against an
involuntary connection! Before making electric connections check
that the tension corresponds to those of the humidifier!

6.5 Connections
6.6 Control System
The terminals of control and alarm signals are located on the electronic control board
(connector 1 – see Figure 1 - Electronic Board) (remove the lower panel of the case to reach
them). The openings for the cables are located on the lower side of the case. Use cables
with a section of max. 1sqmm.
The electronic controller embedded can use an external signal (from an external controller)
or internal proportional controller.
According to the operating process chosen, select suitable connection in the list.
Embedded Proportional Controller
External ON/OFF controller or Humidistat
Connect the external Controller to the
terminals REG and V+ as in the schematic
To use the embedded proportional controller
connect the humidity probe (4… 20 my) as
indicated in the schematic. The humidity
probe must be installed in the room or conduit
to be controlled.
If the enable signal is not used connect V+ et
REG
Use R13 potentiometer on the control board to
regulate the request of humidity (0% clockwise
and 100% counter-clockwise)

External PROPORTIONAL controller (0..10V)
7 Led Indications
The working operation and status of the humidifier is indicated using 4 LEDs on the front
panel.
7.1 Normal Operations
In the case of normal operation the green led (1) is lit with an intensity proportional to the
mist production. If the external or internal controller does not require mist production, the
green led (1) blinks.
In the case of absence of water (insufficient pressure or solenoid input valve failure) the
yellow (4) led light to indicate that there is no mist production.
Red led (2) and (3) must be OFF.
7.2 Tank Cleaning
The microprocessor based control system, performs automatic tank cleaning at start-up and
every 6 hours of operation. This cleaning phase allows limestone deposit to be eliminated
from the tank.
During this cleaning phase green led (1) blinks to indicate that the humidifier is working,
but not producing mist.
Tank cleaning is performed in two phases signalled by a different state of red led (2):
Water input in the tank and starting of the siphon system (red led (2) is ON)
Cleaning and draining of the tank (red led (2) is blinking)
The yellow led (4) indicates the level of water in the tank.
Connect the external Controller to the
terminals REG and 0V as in the schematic

8 Alarm Conditions
In case of failure the micro-controller based board stops mist production and water input.
After a wait period of 5 minutes the humidifier automatically start with tank cleaning
phase.
During the stop phase green led (1) is OFF, red led (3) could signal FAN failure; red led (2)
and yellow led (4) identify the failure.
8.1 Water Failure
This failure is signalled with yellow led (2) blinking and green led (1) OFF.
8.2 Draining System Failure
Draining system failure during tank cleaning phase. The causes of this failure can be a
problem with draining solenoid valve or an obstruction in the draining system (pipes).
This failure is signalled with red led (2) blinking and green led (1) OFF.
9 Tank draining
When the humidifier is not used is mandatory to execute a manual draining. To complete
this operation execute following steps:
1. Close input valve
2. Switch OFF the unit
3. Switch ON the unit
4. Wait until tank is empty
1. Green LED blink
2. Yellow LED is ON
5. Switch OFF the unit

10 Submerged Pump 220Vac
The unit can operate with a pump feeding the humidifier. In the case of use of a submerged
220Vac pump, power supply of the pump must be carried out according to the following
schematic.

The installation of the pump with the tank must respect the outline of below figure. The
tank can be installed in a position higher than the humidifier. If the tank is installed in a
position lower than the humidifier the difference between solenoid valve and the bottom of
the tank should not exceed 60cm with the standard pump provided by Elsteam.
