Power supply voltage selection [ CH004N0003 only]
230
115
Fig. 3.r
Humidifi er model CH004N0003 can be powered at either a nominal
voltage of 115 Vac 50/60 Hertz or a nominal voltage of 230 Vac 50/60
Hz. The factory setting is 230Vac. If the mains power supply is 115 Vac,
the setting must be changed, following the procedure described below:
1.
Make sure the power cable is disconnected from the mains power supply
and that the power button is in the OFF position.
2. Remove the top cover from the unit (see par. 3.2).
3. Set the line voltage selector (shown in the fi gure) to the desired voltage.
4. Close the cover on the unit.
3.8 Power wiring
To connect the humidifi er to the mains:
• once the power cables have been run into the unit, use the cable
clamps illustrated in Fig 3.o to secure them in the correct position;
• connect the power cables to the terminal block at the bottom left of
the control module, as illustrated in Fig. 3.p;
• connect the yellow-green wire to the earth terminal on the unit
located on the metal support plate under the control module (Fig. 3.q).

3.9 Control wiring
On compactSteam, steam production is controlled by an external signal:
• in
on/off mode, a simple contact (for example a humidistat) enables/
disables steam production;
• in proportional mode, the humidifi er produces a quantity of steam
that is directly proportional to the 0 to 10 V signal generated by an
external control device.
compactSteam can be connected to any simple or automatic humidistat
or safety device, such as limiter humidistat, air fl ow control switch and
remote ON/OFF switch. To connect an external control device, run the
cables through the bottom part of the appliance until reaching the top
of the control module, and secure them with the cable clamp (see Fig.
3.s). The control wiring terminal blocks are located at the top right of the
control module (see Fig. 3.r and 3.s)
IMPORTANT NOTE: Select the correct type of control signal on the
keypad (see paragraph 5.1.1) before connecting the control wiring.
