NOTICE:
the drain water must be able to flow freely.
Water connections (parts not included):
NOTICE: for the Australian market and to comply with Watermark
requirements, a watermarked approved dual check valve shall be installed
in the supply line to the humidifier when connected to potable water.
Should on the other hand the humidifier be fed with treated water from a
Carel reverse osmosis system connected to potable water, the dual check
valve shall be installed in the supply line to the reverse osmosis system.
Ƒ
1. Install a manual shut-off valve upstream of the installation (so as
to shut off the water supply);
Ƒ
2. use a hose to connect the humidifier to the water supply for
external diameter of 8 mm and internal of 6 mm (a quick-fit
elbow connector is supplied with the product);
Ƒ
3. install a mechanical filter (< 60 μm) - no included - to trap any
solid impurities (connected downstream of the water tap);
Ƒ
4 connect a section of drain hose, minimum inside diameter 6
mm;
Ƒ
5 prepare a funnel to interrupt continuity in the drain line;
Ƒ
6 connect a drain trap to prevent bad odours.
NOTICE: When installation is completed, flush the supply hose for around
30 minutes by piping water directly into the drain, without sending it into
the humidifier. This will eliminate any scale or processing residues that
may block the fill valve.
4.1 Supply water
The ultrasound humidifier works on demineralised water. Using normal
water will shorten transducer life; specifically, maintenance intervals
for cleaning or replacing transducers depend on to what extent the
supply water mineral content exceeds the values recommended in Table
"Technical specifications". In the case of use of mains water, it is possible
a reduction in the production of moisture due to salts and impurities
present.
Operating conditions:
•
demineralised water with the characteristics indicated in 'Technical
specifications (supply water)';
•
pressure between 0.1 and 0.6 MPa (14.5 and 87 PSI), temperature
between 1 and 40 °C (33.8 and 104 °F), G1/8 F connection (see
‘Technical specifications’);
•
no organic compounds.
DANGER:
•
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. Bacteria and viruses can enter the
air we breathe via contaminated water and cause serious illness.
4.2 Drain water
This is not toxic and can be drained into the sewerage system, as defined
by Directive 91/271/EEC concerning urban waste water treatment.
