2. WATER
CONNECTIONS
Important: before proceeding with the water connections,
make sure that the humidifi er is not connected to the mains power
supply.

ater connections (parts not included):
□
1.
Install a manual shut-off valve upstream of the installation (so as to
shut off the water supply);
□
2.
use a hose to connect the humidifi er to the water supply for
external diameter of 8 mm and internal of 6 mm (it is supplied a
elbow connector with the product);
□
3.
install a mechanical fi lter (< 60 μm) - no included - to trap any solid
impurities (connected downstream of the water tap);
□
4
connect a section of drain hose, minimum inside diameter 6 mm;
□
5
prepare a funnel to interrupt continuity in the drain line;
□
6
connect a drain trap to prevent bad odours.
Important
: When installation is completed, fl ush the supply hose
for around 30 minutes by piping water directly into the drain, without
sending it into the humidifi er. This will eliminate any scale or processing
residues that may block the fi ll valve.
2.1 Supply
water
The ultrasound humidifi er works on demineralised water. Using normal
water will shorten transducer life; specifi cally, maintenance intervals for
cleaning or replacing transducers depend on to what extent the supply
water mineral content exceeds the values recommended in Table 11.b
(p.24). In the case of use of mains water, it is possible a reduction in the
production of moisture declared in Table 11.a due to salts and impurities
present.
Operating conditions:
•
demineralised water with the characteristics indicated in Table 11.b,
supply water (p. 24);
•
pressure between 0.1 and 0.4 MPa (14.5 and 58 PSI), temperature
between 1 and 40 °C (33.8 and 104 °F), G1/8 F connection (see par. 11.2
‘Technical specifi cations’);
•
no organic compounds.
Important:
•
do not add disinfectants or anticorrosive compounds to the water, as
these are potential irritants;
•
the use of well water, industrial water or water from cooling circuits
and, in general, any potentially chemically or bacteriologically
contaminated water is prohibited.
2.2 Drain
water
This is not toxic and can be drained into the sewerage system.
(Council Directive 91/271/EEC on Urban Waste Treatmen).
