2. CABINET INSTALLATION
2.1 Positioning
The cabinet, being IP20, must be installed in a closed compartment,
sheltered from the rain, water spray and direct sunlight.
The cabinet must be installed in an environment with a temperature
between 5 and 40°C.
Around 1 m clearance must be left in front of the cabinet to allow the
door to be opened and maintenance to be performed. Around 0.5 m
clearance needs to be left on both sides of the cabinet to allow space for
the water connections on the right and electrical connections on the left.

2.1.1 Wall mounting
The cabinets can be wall-mounted or floor-standing.
In the event of wall mounting, it is recommended to use the metal frames
and screws supplied. See the distances shown in the following image for
drilling the holes and fastening the brackets.

2.1.2 Floor-standing installation
For floor-standing installation, the unit needs to rest on a raised platform
so as to allow connection of the drain hose, located on the bottom of the
cabinet (see chapter 2.2.3).

2.2 Cabinet water connections
2.2.3 Feedwater line
An expansion vessel should always be installed upstream of the cabinet,
so as attenuate variations in pressure in the feedwater line. A 10 µm mesh
filter should also be installed, in addition to the filter already supplied
inside the cabinet. Finally, an on-off ball valve should be installed on
the line upstream of the cabinet, so as to allow for any maintenance
operations on the water circuit downstream.
Fig. 2.d
A hose with a minimum diameter Ø=1/2” should be connected upstream
of the cabinet so as to ensure the right flow-rate and pressure to the
humidifier. The humidifier inlet connection is 3/4” GAS F. The required
humidifier inlet pressure is at least 3 bars.
