Water connections:
Important: for the Australian market and to meet Watermark
requirements, a Watermark approved double check valve must be
installed on the humidier feedwater line when connected to the potable
water supply network. If, on the other hand, the humidier is supplied
with water from a Carel reverse osmosis system connected to the potable
water supply network, the double check valve must be installed on the
inlet to the reverse osmosis system.
1. install a manual valve upstream of the installation (to be able to cut
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”page41,compatibleCAREL hose: code FWH3415003).
On models UE025 to UE065 connect the hose with the non-return
valve supplied (code FWH3415003) 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 tap);
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”);
5 prepare a funnel to interrupt continuity in the drain line;
6 connect a drain trap to prevent the return of bad odours (minimum
inside diameter 40 mm/1.6”);
7 in models UE025 to UE065: connect a drain hose from the bottom
tank of the humidier (this can run into the drain funnel).
Important
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.
Important:It is mandatory to connect the supply-water piping,
regardless its material, to the protective earth according to the
applicable national and international safety standards.

• 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.

3. STEAM DISTRIBUTION
For the correct delivery of steam, a steam distributor must be used, sized
according to output of the humidier.
In addition, the distributor must be installed in a part of the steam bath

3.3 Steam hoses
•use CAREL hoses (max. 4 m long, see“Models of steam hoses”, page 41).
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 humidier and the
steam distributor using metal clamps, so that these do not detach due
to the high temperature.
3.4 Condensate drain hose
During the operation of the humidier some of the steam may condense,
causing a decline in eciency 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 humidier (see Fig. 3.d). CAREL
condensate drain hoses: code 1312353APG
Important:
Important: the drain trap in the condensate drain hose must be
lled with water before starting the humidier.
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 ttings with metal clamps;
the curves in the tubing are suciently 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 sucient 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 (lled with water before starting operation) to avoid steam
being released.

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 humidier power line must be tted, by the installer, with
a disconnecting switch and fuses protecting against short circuits. Table
12.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.

4.9 Control of production from serial port
(BMS)
You can set the electronic control to use as a primary control analogic
signal value from the serial port instead of the electrical terminals
M2.1-M2.2.
It ‘can set the electronic control to use as the main analog signal
adjustment value from the serial port instead of the electrical terminals
M2.1-M2.2.
This value will be used according to selections made on the parameters:
“Installer / Regulation Type / Select Regulation” corresponds to the
variable non-volatile serial Digital 65, and “Installer / Regulation Type /
Select Regulation” against the non-volatile serial Full Variable 7 (if” Type
regolation CONTACT = ON / OFF “, the value from the serial port will be
used instead of reading CONTACT ON / OFF).
Probe alarms are not connected in this case disabled.
Note: If you set “Type Regolation = 2 Probes Temperature”, in reality
the two spacecraft will be internally assigned a weight 0% and 100%
weight is therefore assigned the value of the rst probe from BMS.
If serial communication is interrupted (no data destined to the control
for a set time), the production will stop and will sound an alarm, the
production will resume restoration of serial communication.
Operate as follows:
• Parameter “Installer / Supervisor / Supervisor (2/2) / Reg. from BMS ‘:
default o, set to ON (or via serial non-volatile digital serial Variable 80:
default 0, set to 1)
• Variable volatile serial Full 31: Set a value between 0 and 1000:
Proportional: tenths of a percentage, Temper: tenths of ° C / ° F,
humidity: tenths of RH%.
• Variable Serial Digital 10: warning SERIAL OFFLINE
• Parameter“Installer / Supervisor / Supervisor Connect / Oine al. Delay
“(or via serial Variable nonvolatile serial Full 108): SERIAL OFFLINE alarm
detection time in seconds, default 60.
4.10 Stop production from serial port (BMS)
You can stop the output from the serial port.
In addition to the detention serial, there are also the following stops:
• on/o Terminal
• on/o By remote contact
If even a single rm is active production stops.
To stop the production serial follow these steps:
• Parameter “Installer / Supervisor / Supervisor Connect / Enable ON /
OFF from supervisor” (or via serial non-volatile digital serial Variable 81:
default 0, set to 1): Set to Yes
• Variable volatile digital serial 8: ON / OFF serial, default o (0); set to 0 to
stop, 1 for non-stop production.
4.11 Modbus® protocol
The protocol Modbus ® is available by selecting from the menu installer
mask supervisor.
Chapter 12.6 shows a list of variables and the corresponding addresses.
For multiple read/writes, the maximum number of “Register” or “Coil”
variables is 20.
The following functions are available:
MB_READ_COIL_STATUS 1: used to request the status (ON or OFF) of a
certain number of “Coil”variables (binary, 1
bit), starting from the specied address.
MB_READ_INPUT_STATUS 2: operationally identical to the above
MB_READ_HOLDING_REG 3: used to request the value of a consecutive
block of “Register”variables (nu-meric, 16
bit)
MB_READ_INPUT_REG 4: operationally identical to the above
MB_FORCE_SINGLE_COIL 5: used to set the status of an individual
“Coil”variable (binary, 1 bit) to ON or
OFF (specifying the address of the bit in
question)
MB_PRESET_SINGLE_REG 6: used to set the value of an individual
“Register” variable (numeric, 16 bit)
MB_FORCE_MULTIPLE_COIL 15: used to set the status of a consecutive
block of “Coil” variables (binary, 1 bit)
(specifying the number of bits and number
of bytes)
MB_PRESET_MULTIPLE_REG 16: used to set the value of a consecutive block
of “Register”variables (nume-ric, 16 bit)
