1.4 Opening the packaging
□make sure the humidifier is intact upon delivery and immediately
notify the transporter, in writing, of any damage that may be due to
careless or improper transport;
□move the humidifier to the site of installation before removing from
the packaging, grasping the neck from underneath;
□open the cardboard box, remove the protective material and remove
the humidifier.
1.5 Material supplied
Make sure the following are included:
1. baffle with 2 bolts;
2. user manual.
1.6 Preparing for assembly
Important: avoid installing the humidifier in the duct in a position
where it may get wet.
• The unit is designed for assembly in compact air-conditioning units,
ventilation systems and air ducts.
• To ensure a very short free path, the atomised water needs to be
delivered as uniformly as possible along and across the duct or the
unit.
• Install the humidifier in position where it is easily accessible/removable
for maintenance or repairs;
• Make an inspection opening on the wall of the ducting;
• To maximise absorption of atomised water in the air flow, for air
handling units with:
- is centrifugal, remove the deflector (D),
- is axial or tangential, install the deflector (D).
D
AIR
Fig. 1.b
• Place a drain tank underneath the humidifier to collect any condensate;
this must be at least 0.6 m long and cover the free path. Install a drain
line with drain trap: the height of the drain trap must exceed the
system static pressure to ensure adequate draining of the tank.
• Air velocity in the duct must be between 1.5 and 3 m/s, so that the
atomised water is rapidly dispersed. In the event of faster air flows,
the cross-section of the duct must be increased so that the velocity is
within the allowed range. The length of the widened section must be
at least 0.6 m beyond the humidifier in the direction of air flow, so as to
minimise condensation on the walls of the ducting or air handling unit.

Important:
1. Choose the installation position so that the air flow disperses the
atomised water uniformly;
2. Make sure that the supporting surface is able to support the weight
of the unit.
The humidifier can only be activated (atomised water production)
when the air handling unit fan is running. NEVER start atomised water
production without air flow in the duct: this may damage one or more
parts of the appliance.
1.7 Assembly
The appliance must be assembled on a horizontal support. Check correct
positioning using a spirit level.
Procedure:
1. Unscrew the screws (A) and remove the right side cover (B);

Fig. 1.d
2. Secure the humidifier to the horizontal support using the fastening
brackets on the right and left sides;
Fig. 1.e
Important:
1. Install the humidifier in horizontal position, using a spirit level, so
that the level sensor does not give a false reading;
2. Carefully secure the unit so that it does not move during operation.

1.10 Operating principle
The operation of humiSonic humidifiers is based on the principle of
atomisation of demineralised water using ultrasound technology. The
humidifier operating principle can be summarised as follows:
• water fill via a fill solenoid valve until reaching the required level,
measured by the float;
• if the autotest is enabled (default), the drain solenoid valve opens and
empties the tank (function designed to clean the tank of any residues/
dirt);
• water filled again to the required level;
• start ultrasonic atomisation (the air flow in the duct carries the particles
of moisture and distributes them into the surrounding environment);
• water refill based on the float measures that the level has fallen below
the recommended value.
Ultrasound technology uses a voltage input signal that is transformed
via an oscillating circuit into a high frequency signal (1.7 MHz). This signal
supplies a transducer, the top of which is in contact with the water, which
starts vibrating at high frequency. The surface of the transducer vibrates
at very high speed (1.7 million times a second), a speed that does not
allow the water to move, due to its inertial mass. Consequently, a column
of water is created above the transducer. During the negative amplitude
of the transducer cycle, a void is created that is not filled by the water (as
this cannot respond to the extremely fast movements of the transducer).
The cavity thus created leads to the production of bubbles that are
pushed to the edge of the water column during the positive amplitude
of the cycle, thus colliding. During this process, very fine particles of water
are atomised on the edge of the water column. The resulting intersecting
sound waves created directly underneath the surface of the water cause
very small droplets of water to separate, forming a fine mist of vapour
that is immediately absorbed by the flow of air.

2. WATER CONNECTIONS
IMPORTANT: before proceeding with the water connections,
make sure that the humidifier is not connected to the mains power
supply.
2.1 Warnings
1. Onlyusedemineralisedwater.Installashut-offvalveforeachhumidifier.
Allowable water pressure: from 1 to 6 bars;
2. Theconnectionsbetweenthepipes/hosesincontactwithdemineralised
water and the humidifier must be made from resistant material
suitable for this use (e.g. PVC or stainless steel);
3. Thewaterlinesmustnotbefouledbydustparticlesorothersubstances.
Carefully clean the lines before connecting to the
humidifier;
4. AllhumiSonic ultrasonichumidifiers aresupplied with quick couplings
for connecting the fill hose (OD / ID = 8/6 mm).
2.2 Water connections (parts not included)
• Install a manual shut-off valve upstream of the installation (so as to
shut off the water supply); the valve must be suitable for use with
demineralised water.
• Install a mechanical filter (10 m) downstream of the manual shut-off
valve to trap any solid impurities; the filter must be fitted with shut-off
devices to allow cleaning;
• Install a condensate collection basin that is at least 0.6 m longer than
the humidifier, made from corrosion-resistant material such as plastic
or stainless steel.
Important:
1. when installation is completed, flush the supply hose for around 30
minutes by piping water directly into the drain, without sending it
into the humidifier. After installing the valve, flush with water to
eliminate any processing residues and oil and prevent that enter the
humidifier;
2. the drain hose must have a minimum diameter of 6 mm; it must
not have any bends that block water flow; the drain line must
comply with national and local standards in force and must include
a funnel to ensure interruption of continuity and a drain trap
to prevent the return of bad odours. The end of the line must have a
downwards slope to assist drainage;
3. do not block the atomised water outlet or the intake air
openings;
4. always check for water leaks. If the humidifier is sprayed with water
during operation, short circuits may occur;
5. if there is the risk of the feedwater freezing, insulate the
water pipes.

2.3 Positioning
As seen in chap.1, the humidifier must be installed in ducting where the
air velocity is between 1.5 and 3 m/s.
Note: when calculating air velocity in the duct, keep in mind that the
area occupied by the humidifier needs to be subtracted from the cross-
section of the duct.
The recommended position is downstream of the heating coil.

If assembling multiple humidifiers, arrange them in a structure that can
support the weight of the appliances and that leaves optimum space
between the units, so as to ensure efficient operation. Install a manual
shut-off valve for each humidifier.
Note: any obstacles in front to the humidifier are places where water
may condense.

2.5 Feedwater
To ensure correct operation, humiSonic requires the use of demineralised
water, with the chemical and physical characteristics specified in the table.
To ensure these water quality values, a reverse-osmosis demineralisation
system is typically used.

Tab. 2.a
(1) = in general CR=0,65 * σR,20 °C; R180 = 0,93 * σR,20 °C
To avoid excessive oversizing of the reverse osmosis system, it is
recommended to avoid sizing the system based on instant flow-rate.
Rather, an expansion vessel should be installed between the water
treatment system and humiSonic.
The sizing calculations need to consider discontinuous water
consumption, comprising the following stages:
• filling (fill valve open);
• production (fill valve closed);
• washing (fill valve open).
The table below suggests the minimum sizes for connection to a generic
reverse osmosis system.

UU09 5.2 l 20.8 l 14.8 l/h
UU14 6.8 l 27.2 l 20.8 l/h
UU18 8.0 l 32.0 l 26.0 l/h
Tab. 0.a
If no storage vessel is available, the reverse osmosis system must
guarantee the instant flow-rate of the fill SV, equal to 2 l/min.
Connecting humiSonic to the Carel WTS Compact
The Carel product range includes a series of reverse osmosis systems
(“WTS Compact”) designed to produce water according to the feedwater
specifications and optimise connection to and operation with humiSonic
(see manuals +0300017 and +0300019).
All WTS Compact systems (P/N ROC%) always come with an expansion
vessel that maintains the required pressure in the circuit downstream.
Operation of the system is managed by pressure switches in the outlet
circuit. The basic rule for connection to the humidifier is that the water
contained in the expansion vessel must be sufficient to satisfy initial filling
and, if necessary, the washing cycle, while the WTS production time must
cover humiSonic production demand and fill the vessel as quickly as
possible.
The table below suggests the water consumption values and connections
for all sizes of humidifiers.

Tab. 2.b
(*) Water consumption during the washing cycle is calculated based on
the default settings (1 wash every 24 hours, lasting 2 minutes, which ends
by totalling filling and emptying the volume of the tank). Consumption
depends on the fill solenoid valve flow-rate, which is 2 litres/minute. The
duration and frequency of the washing cycles are parameters that can be
set by the user, and these have a significant impact on the sizing of the
WTS system.
Important:
1. do not add disinfectants or anticorrosive compounds to the water, as
these are potential irritants;
2. the use of well water, industrial water or water from cooling
circuits and, in general, any potentially chemically or bacteriologically
contaminated water is prohibited.
2.6 Drain water
This is not toxic and can be drained into the sewerage system, as defined
by directive 91/271/EEC on urban waste-water treatment.

3. ELECTRICAL CONNECTIONS
3.1 Humidifier electrical connections
Important
Important:
• before proceeding with the electrical connections, ensure that the
control panel – humidifier system is disconnected from the mains
power supply;
• make sure that the power supply voltage of the control panel
corresponds to the value indicated in the rated data.
To power up the humidifier, connect the cables running from the
electrical panel:
1. +48 Vdc/ -48 Vdc from the power supply;
2. +24 Vac/ -24 Vac from the transformer;
3. the power cable for the lights (“Slave”electrical panel only);
4. the cable for the signal lights (“Slave”electrical panel) or RS485 serial
line (“Master”electrical panel).
After having removed the screws (A), remove the side cover (B) and run
the cables through the cable glands on the case and inside the unit
(C). Then make the electrical connections (D) and reposition the cover,
repeating the same operations in reverse.

HUMIDISTAT OR REMOTE CONTACT (ON/OFF action)
Production is enabled by closing the ONOFF – COM contact on the
terminal block. This can be connected to a switch, a humidistat or a
controller (voltage-free contact, max 5 Vdc open, max 7 mA closed).
RS485 SERIAL CONNECTION
CAREL/ Modbus protocol: -TXRX-, +TXRX, 0TXRX terminals.
Important
Important: for RS485 connections in household (IEC EN 55014-1)
and residential (IEC EN 61000-6-3) environments, use shielded cable (with
shield connected to PE both on the terminal and controller ends),
maximum length specified by the EIA RS485 protocol, equivalent to
European standard CCITT V11, using AWG26 twisted pair cable; the input
impedance of the 485 stage is 1/8 unit-load (96 kOhm). This configuration
allows a maximum of 256 devices to be connected, with cables in
separate conduits from the power cable.
ALARM RELAY
Terminals: AL_B, AL_A
Ready for remote signalling of one or more alarms.
Note: in industrial environments (IEC EN61000-6-2) the signal cables
leaving the unit must not exceed 10 m (33 ft) in length: remote on/off digital
input (ON/OFF - COM terminals) and shielded cable for RS485 communication.
3.8 Connection cable sizing
The table below shows the sizing of the 48 Vdc connection cable between
the humidifier and the “Slave” or “Master” electrical panel. The minimum

4. STARTING AND USER INTERFACE “SLAVE” PANEL
Before starting the humidifier check:
• water connections: in the event of water leaks, do not start the
humidifier before having restored the connections;
• electrical connections between the humidifier and the control panel.
4.1 Starting
See chap.“Electrical connections”
1. Thehumidifier,once poweredand enabled forproduction(remoteon-
off/humidistat), is ready for operation.
2. Operation will only stop if the enabling signal is no longer present.
4.2 Shutdown / Standby
1. To switch the humidifier off, press the ON/OFF button.
2. The humidifier goes into standby when:
• the remote on/off contact is open;
• the on/off contact is open and serial enabling is set to 1 (see
chapter “Humidifier control via network“).
When the humidifier is in standby, the tank is emptied automatically
4.3 Autotest
When the humidifier is first started (from off ), if enabled and humidity
production is required, a test cycle is run. A complete fill and drain cycle
is performed, during which the level sensor is monitored; if the test is
successful, regular atomised water production will start. If the test fails,
production is disabled (see the alarm table).
4.4 Signal lights on the “Slave” panel
Blue light
Steady Humidity production
Slow flash* Standby
Fast flash** Autotest or wash
* Slow flash: 1 s ON and 1 s OFF
** Fast flash: 0.2 s ON and 0.2 s OFF
The red LED means an alarm is active. See the chapter on Alarms for the
alarm table.
4.5 Disabling
The humidifier can be disabled in three different ways:
• Opening the COM-ONOFF contact (enabling signal);
• Active alarms;
• Via network.
4.6 Reset tank hour counter
The humidifier is fitted with an hour counter that records operation.
After a set number of hours (5,000), a signal is activated to indicate
maintenance should be performed on the tank and operation of the
piezoelectric elements checked (see the chapter on Maintenance). To
reset the hour counter at any time, proceed as follows:
• switch the humidifier off;
• close the water supply tap and wait for the tank to empty completely;
• remove the front panel from the humidifier to access the control board;
• unplug the Lumberg connector on the control board;
• open the On/Off contact;
• switch the humidifier on (with the Lumberg connector disconnected
from the control board). Both lights will flash;
• close the On/Off contact. The yellow LED will remain on steady;
• switch the humidifier off;
• plug the Lumberg connector (A) onto the board, making sure it is
inserted in the correct direction;
• switch the humidifier on.

Fig. 4.a
4.7 Automatic washing
The humidifier automatically runs a washing cycle at set intervals (default
60 minutes) during which time atomised water is produced. The washing
cycle involves a complete drain cycle, a phase in which fill and drain are
activated together (1 minute) to flush out any residues in the tank, a
complete fill cycle and finally another complete drain cycle. During this
operation, atomised water production is stopped.
4.8 Washing due to inactivity
If the humidifier remains inactive (on but in standby) for an extended
period (24 hours) a washing cycle is performed, as described in the
previous paragraph. This cleans the tank of any residues (e.g. dust) that
may have accumulated during the period of inactivity. The washing cycle
is run after 24 hours (continuous) of no operation, i.e. the humidifier is in
standby.
