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 battery of the cold, with the control group placed on the
sides of the central where inspection is easier.
If the plant is subjected to shock and transport, secure it with screws.
7.1
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.
7.2
Draining connection
If it is possible, simply leave the drain pipe in the condensate drain pan of AHU who will then evacuate
through his drain system.
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.
7.3
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.
Before starting ensure the following conditions:
The size of the power cables must be convenient to the maximum current that must pass
through them.
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.
Before any maintenance and installation power connection should be dis-
continued
and
protected
against
any
accidental
connection.
Before performing the electrical connections make sure that the voltage
available is equivalent to that of the humidifier.
