HUMIDIFIER POWER SUPPLY
Underneath the fill solenoid valve on the steam production unit is
the threaded male fitting (V) for the humidifier water supply.
This is already fitted with a plastic hose, diameter 6 mm, for con-
nection to the building's water supply (see figure, point F).
V: Steam production unit - inlet connection (threaded male fit-
ting 3/4"G);
F: Rubber hose, diameter: Ø 6mm.
To supply the humidifier, use drinking water without any chemical
treatment or demineralisation.
The characteristics of the water that supplies the humidifier must
be within the following values:

The cylinder supplied as indicated in the price list refers to the model for medium conductivity (350...750 µS/cm).
Models are available upon request for low conductivity (125-350 µS/cm) or high conductivity (750-1250 µS/cm).
Contact the office to a specific quotation.
HUMIDIFIER AND CONDENSATE DRAIN
Underneath the drain solenoid valve on the steam production
unit is an attachment for draining the water.
This is already fitted with a hose coupling for connecting the hose
running to the sewerage system in the building.
A rubber or plastic hose should be used, resistant to 100°C, with
an inside diameter of 32 mm.
Fit a trap in the section of the hose outside of the unit to avoid
bad odours and to prevent water from overflowing from the
humidifier pan.
During installation, pour water into the condensate collection pan
and the humidifier pan, so as to fill the drain traps outside and
inside the unit with water.
Downstream of the drain trap ensure a minimum slope of 1%.

WARNING: the water exiting the steam cylinder is very hot.
The humidifier drain hose must not be fastened to electrical
cables and must run down vertically so as to avoid any contact
with these cables.
