1. INTRODUCTION AND ASSEMBLY
1.1 humiSonic (UU0*D)
Range of ultrasonic adiabatic humidifiers for direct humidification in
ducts or air handling units. humiSonic is particularly suitable for many
applications in which optimisation of room humidity is an essential
factor for personal comfort and the quality of goods. The humidifiers are
controlled by an external electrical panel. Depending on the required
functions, this can be the “Secondary” (ON/OFF, status signal, remote ON/
OFF) or “Main” model (user interface and programming).

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 fan that:
- is centrifugal, remove the deflector (D),
- is axial or tangential, install the deflector (D).

• Place a drain tank underneath the humidifier to collect any condensate;
this must be at least 0.6 m (2 ft) 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 (295 e 590 fpm),
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 (2 ft) beyond the humidifier in the direction of
air flow, so as to minimise condensation on the walls of the ducting or
air handling unit.
