Water connections:
o
1.
install a manual valve upstream of the installation (to be able to
cut off the water supply);
o
2.
connect the humidifi er to the water supply. On models
UE001 to UE0018, use a hose with 3/4’’G fi ttings (see par.
“Technical specifi cations” page 41, compatible CAREL hose:
code FWH3415000). On models UE025 to UE130 connect the
hose with the non-return valve supplied (code FWHDCV0000)
to prevent the water inside the humidifi er from coming into
contact with the mains water;
o
3.
install a mechanical fi lter to trap any solid impurities (to be
connected downstream of the tap);
o
4
connect a section of non-conductive pipe or hose for draining
(resistant to temperatures of 100 °C (212 °F) and with a minimum
inside diameter of 40 mm/1.6”);
o
5
prepare a funnel to interrupt continuity in the drain line;
o
6
connect a drain trap to prevent the return of bad odours
(minimum inside diameter 40 mm/1.6”);
o
7
in models UE025 to UE130: connect a drain hose from the
bottom tank of the humidifi er (this can run into the drain
funnel).
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 drain pump and cause foam
when boiling.
Important: It is mandatory to connect the supply-water piping,
regardless its material, to the protective earth according to the
applicable national and international safety standards.
