HUMIDIFIER POWER SUPPLY
A
I
U
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:
position: V-F

Ø 6mm
OUT
Ø 32mm
HUMIDIFIER AND CONDENSATE DRAIN
A
I
U
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.
CONDENSATE DRAIN PUMP AND HUMIDIFIER DRAIN PUMP
A
I
U
Depending on the version, a condensate drain pump is available
(for versions B and R) or a humidifier drain pump (for versions H
and T) with mechanical features such as to be able to resist the
high temperatures of the water exiting the steam cylinder.
The pump must be located below the drain fitting, according to
the instructions contained in the packaging.
Check that the head is sufficient to lift the condensate to the
point of drainage.
