3.10 POWER SUPPLY VOLTAGE SELECTION

The humidifier can be powered at either a nominal voltage
of 115 Vac 50/60 Hertz or a nominal voltage of 230 Vac 50/60
Hz. If the main power supply is 115 Vac, the setting must be
changed accordingly, following the procedure described
below:
• Make sure the power cable is disconnected from the main
power supply and the power button is in the OFF position.
• Remove the top cover from the unit.
• Set the line voltage selector (shown in Fig. 3.l.) to the desired
voltage.
WARNING: Select desired power supply
voltage. The factory setting is 230 Vac.

3.11 POWER WIRING

Insert the power and ground connection cables into the
electrical panel compartment using the cable clamps (See Fig.
3.m).
Connect the power cables to the terminal block at the bottom
left of the control module; polarity does not matter (See Fig.
3.n).
WARNING: All wiring must be in accordance with local,
state and national electric codes.
NOTE: To avoid unwanted interference, the power cables
should be kept separate from any control wiring.
Connect the ground wire to the unit's chassis ground, located
just behind the power wiring terminal block. (See Fig. 3.o.)
Refer to Table 3.e for electrical specifications.
