HYDRAULIC CONNECTIONS:
1. install a manual valve upstream (to cut o the water supply);
2. connect the humidi er to the water supply. For UR002...UR013 models,
use a  exible pipe 3/4’’G connection. For UR020...UR080 models
connect the  exible pipe with the back ow prevention valve
(supplid - code FWHDCV0003), to avoid the water inside the
humidi er from making contact with the one in the mains;
3. install a mechanical  lter to retain any solid impurities (connect
before the inlet connection of the humidi er.
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 an open drain using a funnel to interrupt drain continuity;
6. connect a trap to prevent the return of odors;
7. for models UR020...UR080: connect a drain pipe from the drain pan
at the bottom of the humidi er (this can run into the funnel used for
draining).
8. for drain tempering versions, water temperature will be 60 °C (140 deg
F), so long as the temperature of the feed water is equal to or less than
25 °C (77 deg F) guaranteed.
Caution:
• once the installation is complete,  ush the supply pipe for about
30 minutes by carrying water directly in the drain and without
introducing it into the humidi 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 (12 in)
( gure) to prevent the return of steam.
