Humidifier installation
The hydraulic part is simply placed inside the compartment of humidification of the AHU on the conden-
sate drain pan immediately downstream of the cold battery, with the control group placed on the sides
of the AHU where inspection is easier.
If the AHU is subjected to shock and transport, secure it with screws.
During the humidifier installation carefully follows these points:
•
The opening and the closing of the power electronic control box takes place through 4 screws
•
Since water is discharged at a temperature of 100 ° C, it is necessary to connect the drain with
a plastic tube of greater length possible (at least 1 meter)
•
The model listed above are only for operation in OEM application within AHU
•
As above said the humidifier of these families cannot be installed in direct contact with people
and objects
8.1
Water connection
The humidifier is connected to the water through a rubber pipe
that can withstand pressure surges, already included in the hu-
midifier, so as to allow a rapid disassembly for inspection and
cleaning of the filter on the solenoid. Connection type is ¾ inch
female
The supply water must not be demineralized water (not having
conductivity, the humidifier does not produce), preferably un-
sweetened, because generally softened water is corrosive for
the electrodes (even if made of stainless steel). Normal water
can be used to feed the humidifier. If the hardness exceeds 30
French degrees, you can provide a partial softening. However,
it can also be used without softening, providing some supplementary maintenance.
Input pressure must be between 2 and 10 bars.
8.2
Draining connection
If it is allowed, it is sufficient for letting the drain in the condensate drain pan of UTA who will then evac-
uated through its draining connection. In this case you have to connect a 90° bend to the draining block.
This connection assures us that the downloaded limestone cannot block the draining outlet
If you are asked to separate the two drain systems, connect the 40 mm humidifier drain pipe with a
sewer drain trap having at least the same cross section.
8.3
Electrical connection
You need to connect the control unit to the power supply making sure that the cables sections comply
with the regulations and that a circuit breaker is installed upstream.
You do not need the neutral and ground lines.
All operations related to electrical installation MUST be carried out by qualified
personnel (eg electrician or staff with appropriate training). The customer is
responsible for the use of qualified personnel.
IF THE HUMIDIFIER IS PLACED IN AN ENVIRONMENT WITH STRONG INTAKE THE 90°
BEND MUST BE DIRECTED IN THE AIRFLOW DIRECTION (otherwise the joined contri-
bution of the aspiration of the air flow on the water and the pressure of the air
onto the draining will prevent a correct draining of kettle).
