WATER CONNECTIONS:
1. install a manual valve upstream (to cut off the water supply);
2.
connect the humidifi er to the water supply. For UR002...UR013 models,
use a fl exible pipe 3/4’’G connection. For UR020...UR080 models
connect the fl exible pipe with the non-return valve (supplied - code
FWHDCV0003), to avoid the water inside the humidifi er making
contact with the one in the mains;
3.
install a mechanical fi lter to retain any solid impurities (connect
downstream with respect to the tap.
4.
connect a section of pipe for draining (resistant to temperatures of
100 ° C (212 ° F)) and with a minimum internal diameter of 40 mm
(1.6 in) for models UR002-UR013 and 50 mm (2 in), for models UR020
UR080;
5. provide a funnel to ensure continuity interruption in the drain piping;
6.
connect a P-trap to prevent the return of odours;
7.
for models UR020...UR080: connect a drain pipe from the tank to
the bottom of the humidifi er (this can run into the funnel used for
draining).
8. for drain tempering versions, water temperature will be 60°C (140°F)
with temperature is max 25°C (77°F) guaranteed.
Caution:
•
once the installation is complete, fl ush the supply pipe for about
30 minutes by carrying water directly in the drain and without
introducing it into the humidifi er. This will eliminate any waste or
processing residues that could clog the inlet valve and/or cause foam
when boiling water;
•
the drain pipe must run vertically downwards at least 30 cm (fi gure 2.a)
to prevent the return of steam.
