WARNINGS
CAREL humidifiers are advanced products, whose operation is specified in the
technical documentation supplied with the product or can be downloaded,
even prior to purchase, from the website www.carel.com. Each CAREL product,
in relation to its advanced level of technology, requires setup/configuration/
programming/commissioning to be able to operate in the best possible way
for the specific application. The failure to complete such operations, which
are required/indicated in the user manual, may cause the final product to
malfunction; CAREL accepts no liability in such cases.
The customer (manufacturer, developer or installer of the final equipment)
accepts all liability and risk relating to the configuration of the product in
order to reach the expected results in relation to the specific final installation
and/or equipment. CAREL may, based on specific agreements, act as a
consultant for the installation/commissioning/use of the unit, however in no
case does it accept liability for the correct operation of the humidifier and the
final installation if the warnings or suggestions provided in this manual or in
other product technical documents are not heeded. In addition to observing
the above warnings and suggestions, the following warnings must be heeded
for the correct use of the product:
• DANGER OF ELECTRIC SHOCK
The humidifier contains live electrical components. Disconnect the
mains power supply before accessing inside parts or during maintenance
and installation.
• DANGER OF WATER LEAKS
The humidifier automatically and constantly fills/drains certain quantities
of water. Malfunctions in the connections or in the humidifier may cause
leaks.

1. INTRODUCTION AND ASSEMBLY
1.1 Ultrasound humidifier
Ultrasound humidifiers can be used for vast variety of applications, e.g.
data centers, climate rooms, close control units and food preservation, for
the RH% control. The 2-transducer version (UU01F) has been specifically
developed for integration into fan coils. Atomised water production is
0.5 l/h (UU01F) and 1 l/h (UU01G), delivered directly into the air stream.

1.3 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,
□The following are contained inside the packaging (fig 1):
• A: fastening bracket;
• B: tank;
• C: fill solenoid valve;
• D: drain solenoid valve;
• E: transformer (make sure voltage is correct);
• F: cable kit.
• G: terminal kit.
1.4 Positioning
• The humidifier may only be accessed by specialist personnel;
• make sure the humidifier is level horizontally, observing the minimum
clearance of 20 mm on the sides to leave room for maintenance;
• position the humidifier so as to allow the atomised water to be freely
delivered;
• position the transformer in a place that’s protected against possible
water leaks and in any case not underneath the humidifier.
1.5 Fastening
Fastening instructions:
1. make two holes as shown in Fig. 1.b;
2. fixthefasteningbracketusingtwoM4x12screwssupplied(seeFig.1.c),
using a spirit level to make sure installation is horizontal;

Important: correct wiring of the ultrasound humidifier is the
responsibility of the final appliance manufacturer, as required by IEC EN
60335-1.
• Connect the valve power cable;
• Connect the transformer power cable.

1. Connect the piezoelectric element power cable;
2. grip the tank A with two hands;
3. place the tank vertically on the fastening structure, first aligning the
connector on the tank with the electronic board, and then the fill
and drain hoses with the corresponding valves;
4. apply pressure vertically until the tank is in position, i.e. the tabs are
aligned.

make sure that the humidifier is not connected to the mains
power supply.

Fig. 2.k
Water connections (parts not included):
□1. Install a manual shut-off valve upstream of the installation (so as to
shut off the water supply);
□2. use a hose to connect the humidifier to the water supply (the
product is supplied with a slide-on elbow connector);
□3. install a mechanical filter (60 μS) to trap any solid impurities
(connected downstream of the water tap);
□4connect a section of drain hose, minimum inside diameter 6 mm;
□5prepare a funnel to interrupt continuity in the drain line;
□6connect a drain trap to prevent bad odours.
Important
Important: 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. This will eliminate any scale or processing
residues that may block the fill valve.
2.1 Supply water
The ultrasound humidifier works on demineralised water. Using normal
water will shorten transducer life; specifically, maintenance intervals for
cleaning or replacing transducers depend on to what extent the supply
water mineral content exceeds the values recommended in Table 11.b
(pg.21). In the case of use of mains water, it is possible a reduction in the
production of moisture declared in Table 11.a due to salts and impurities
present.
Operating conditions:
• demineralised water with the characteristics indicated in Table 11.b,
supply water (p. 21);
• pressure between 0.1 and 0.6 MPa (14.5 and 116 PSI), temperature
between 1 and 40 °C (33.8 and 104 °F), G1/8 F connection (see par.
11.2 ‘Technical specifications’);
• no organic compounds.
Important:
Important:
• do not add disinfectants or anticorrosive compounds to the water, as
these are potential irritants;
• the use of well water, industrial water or water from cooling circuits
and, in general, any potentially chemically or bacteriologically
contaminated water is prohibited.
2.2 Drain water
This is not toxic and can be drained into the sewerage system.
(Council Directive 91/271/EEC on Urban Waste Treatmen).

3. ATOMISED WATER DISTRIBUTION
3.1 Atomised water distributor
Important:
Important: the atomised water delivery hose, the distributor, the
fan conveyor, the elbow connection and the diffuser are not supplied with
the humidifier.
Requirements:
• humidifier delivery hose OD 40 mm;
• make sure the atomised water outlet area is 1100 mm2 (e.g. 22 holes
8 mm in diameter);
• the hose running to the distributor should have a minimum upward
gradient of 2° so that any condensate flows back into the humidifier or
a special condensate drain system;
• make sure there are no condensate leaks from the water vapour
distributor;
• position the distributor in such a way that the air is not directed against
nearby objects (minimum distance 10 cm);
• bends or choking of the hose may cause condensate to form and
decrease humidity delivery;
• avoid loads that may cause mechanical stress on the humidifier outlet
connector.

3.2 Fan conveyor
Fig. 3.c
The air flow conveyor can be installed on the top of the fan (removing
the protection grill) so as to take in air from a different place to where
humiSonic is installed.
3.3 Elbow connector
Fig. 3.d
The elbow connector can be installed on the cover and/or the fan conveyor,
so as to reduce the overall height occupied by the product.
3.4 Diffuser
Fig. 3.e
The diffuser can be installed on the cover, so as to deliver atomised water
directly into the room.
3.5 Filter: 50 micron
Fig. 3.f
A filter is available to be installed on the fan, using the conveyor (with or
without the elbow). The filter is delivered disassembled (cap not fixed)
because on one side it is possible to mount it on the conveyor, on the other
side on the elbow (to mount with a slight interference). Once mounted,
insert the cap. It’s necessary to clean the filter (with compressed air or
running water) periodically: frequency depends on the environment in
which the system is installed. Features filter: 50 micron, H = 13 cm, D = 5 cm
