Power supply voltage selection

Fig. 3.m
Humidifier 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.
3. Set the line voltage selector (shown in the figure) to the
desired voltage.
4. Close the cover on the unit.

3.8 Power wiring

To connect the humidifier to the mains:
• once the power cables have been run into the unit, use the
cable clamps illustrated in Fig 3.n 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.o;
• connect the yellow-green wire to the earth terminal on the
unit located on the metal support plate under the control
module (Fig. 3.p).

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 humidifier 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 flow
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. The control wiring terminal
blocks are located at the top right of the control module.
IMPORTANT NOTE: Select the correct type of control signal
on the keypad (see paragraph 5.1) before connecting the control
wiring.
