Water connections:
1.
install a manual valve upstream of the installation (to be able to
shut o the water supply);
2.
connect the humidier to the water supply. On models UE001
to UE0018, use a hose with 3/4’’G ttings (see par. Technical
speci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 humidier from coming into contact with the
mains water;
3.
install a mechanical lter to trap any solid impurities (to be
connected downstream of the manual valve);
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” up to UE018, and 50 mm/1.9” for
models UE025 to UE130);
5
prepare a funnel to interrupt continuity in the drain line funnel for
required air gap, can be composed of a piping reducer;
6
connect a drain trap to prevent the return of bad odors (minimum
inside diameter of 40 mm/1.6” up to UE018, and 50 mm/1.9” for
models UE025 to UE130);
7
in models UE025 to UE130: connect a drain hose from the bottom
tank of the humidier (this can run into the drain funnel/air gap
reducer coupling).
8
in models UE025 to UE130: connect the hose FWH3415000 for the
drain tempering valve.
Important: when installation is completed, ush the supply hose for
around 30 minutes by piping water directly into the drain, without
sending it into the humidier. This will eliminate any scale or processing
residues that may block the drain pump and cause foam when boiling.
