Water connections:
•
1.
install a manual valve upstream of the installation (to be able to
shut o the water supply);
•
2.
connect the humidier to the water supply. On models UE001
to UE0018, use a hose with 3/4’’G ttings (see par. “Technical
specications” 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 humidier 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 humidier (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 humidier. This will eliminate any scale or processing
residues that may block the drain pump and cause foam when boiling.
