Water connections:
□1. install a manual valve upstream of the installation (to be able
to shut off the water supply);
□2. connect the humidifier to the water supply. On models
UE001 to UE0018, use a hose with 3/4’’G fittings (see par.
11.2 “Technical specifications” , compatible CAREL hose: code
FWH3415000). On models UE025 to UE065 connect the hose
with the non-return valve supplied (code FWHDCV0000) to
prevent the water inside the humidifier from coming into
contact with the mains water;
□3. install a mechanical filter to trap any solid impurities (to be
connected downstream of the manual valve);
□4connect 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 UE065);
□5prepare a funnel to interrupt continuity in the drain line funnel
for required air gap, can be composed of a piping reducer;
□6connect a drain trap to prevent the return of bad odours
(minimum inside diameter of 40 mm/1.6” up to UE018, and 50
mm/ 1.9”for models UE025 to UE065);
□7in models UE025 to UE0065: connect a drain hose ( minimum
inside diameter 15 mm ( 0.59” )) from the bottom tank of the
humidifier (this can run into the drain funnel).
□8in models UE025 to UE065: connect the hose code
FWH3415000 for the drain tempering valve.
Important
Important: when installation is completed, flush the supply hose for
around 30 minutes by piping water directly into the drain, without
sending it into the humidifier. This will eliminate any scale or processing
residues that may block the drain pump and cause foam when boiling.

2.1 Supply water
Only use mains water with:
• pressure between 0.1 and 0.8 MPa (14.5 and 116 PSI), temperature
between 1 and 40 °C (33.8 and104 °F) and an instant flow-rate no lower
than the rated flow of the fill solenoid valve, the connection is G3/4M (see
par. “11.2 Technical specifications”);
• range hardness 10° to 40 °f (equal to 400 ppm of CaCO3), conductivity:
75 to 1250 µS/cm;
• no organic compounds.

Important:
Important:
• do not treat the water with softeners, this may cause the entrainment of
foam, affecting the operation of the unit;
• do not add disinfectants or anticorrosive compounds to the water, as
these are potential irritants;
• the use of well water, industrial water or water from cooling circuits and,
in general, any potentially chemically or bacteriologically contaminated
water is not recommended.
2.2 Drain water
this contains the same substances dissolved in the supply water, however
in larger quantities;
• it may reach a temperature of 100 °C (212 °F);
• it is not toxic and can be drained into the sewerage system.
2.3 Drain tempering
The unit is fitted with a tempering valve that, opening at the same time as
the drain valve, adds cold water to the drain line, thus ensuring a maximum
temperature of the drain water of 60°C/140°F.
Note: The use of the drain tempering option, increase the flow rate of the
drain water.

Note: if steam hoses with an inside diameter of 30 mm (1.2”) are
used, remove the 22 mm (0.9”) steam inlet section.
3.2 CAREL linear distributors for air ducts
(DP***DRU)
Install away from obstacles (curves, branches, changes in cross-section, grills,
filters, fans).
Minimum distance between the distributor and the obstacle: 1/1.5 m
(3.3/4.9 ft). Increase the distance if:
• the air speed increases in the duct,
• the relative humidity of the air increases before and after humidification,
• the turbulence decreases.
See page 33 for installation examples.
Assembly instructions (see Fig.3.b):
• make a series of holes on the wall according to the distributor drilling
template (included in the packaging with the distributor);
• insert the distributor with the steam holes facing upward;
• fasten the flange using 4 screws.

3.4 Steam hoses
• Use CAREL hoses (max. 4 m long, see “Models of steam hoses”, page 30).
Rigid pipes may break and cause steam leaks;
• avoid the formation of pockets or traps (causes of condensate);
• avoid choking the hose due to tight bends or twisting;
• fasten the end of the hose to the connectors on the humidifier and the
steam distributor using metal clamps, so that these do not detach due to
the high temperature;
• avoid situations that cause stress on the outlet of the steam cylinder.
3.5 Condensate drain hose
During the operation of the humidifier some of the steam may condense,
causing a decline in efficiency and noise (gurgling).
To drain the condensate, connect a drain hose with a drain trap and a
minimum slope of 5° to the bottom of the humidifier (see Fig. 3.d). CAREL
condensate drain hoses: code 1312353APG
Important
Important: he drain trap in the condensate drain hose must be
filled with water before starting the humidifier.
Example of correct and incorrect installation of the steam hose and
condensate drain hose.
Final checks
□the steam outlet hoses run upwards and the distributor has a minimum
incline of 2° upwards (see Fig. 3.c);
□the ends of the hose are tightened to the fittings with metal clamps;
□the curves in the tubing are sufficiently wide (radius > 300 mm / 11.8”) so
as to not cause bending or choking;
□the steam hose has no pockets or traps for condensate to form;
□the paths of the steam and condensate hoses are as described in this
chapter (see Fig. 3.d);
□the length of the steam hose is no greater than 4 metres (13.1 feet);
□the incline of the steam hose is sufficient to allow correct draining of
the condensate (> 20° for the upward sections, > 5° for the downward
sections);
□the incline of the condensate hose is at least 5° at every point;
□the condensate hose always follows a downwards path and features a
drain trap (filled with water before starting operation) to avoid steam
being released.

3. probe cable inlet. On models UE001 to UE018, remove the plastic “tab”
and use it to secure the cable (held in place by the screws provided).
4.2 Power cable connection
Before making the connections, ensure that the machine is
disconnected from the mains power supply.
Check that the power supply voltage of the appliance corresponds to
the value indicated on the rating plate inside the electrical panel. Insert
the power and ground connection cables into the electrical panel
compartment using the tear-proof cable gland supplied, or through the
cable gland with cable stop, and connect the ends to the terminals (see
Fig. 4.c). The humidifier power line must be fitted, by the installer,
with a disconnecting switch and fuses protecting against short circuits.
Table 11.a lists the recommended cross-sections of the power supply
cable and the recommended fuse ratings; note, however, that this data
is purely a guide and, in the event of non-compliance with local
standards, the latter must prevail.
Note: to avoid unwanted interference, the power cables should be
kept apart from the probe signal cables.
