Extended Shutdown
Should it be required to disconnect power to the humidifier for a period of extended shut-down,
always drain the cylinder first.
1 Switch the On/Off/Drain Switch to the Drain position.
2 Wait until the humidifier is completely drained (usually takes less than 10 minutes).
3 Turn the On/Off /Drain switch to the off position.
4 Shut off power to the humidifier with the external disconnect.
5 Close the supply water shut-off valve.
Starting After Extended Shutdown
1 Check to see the humidifier has not been damaged and the installation has not been
altered. Refer to the Chapter on Start Up.
2 Turn on the power to the humidifier with the external disconnect.
3 Turn the On/Off/ Drain switch to the Drain position.
4 Wait until there is no water flowing to drain. It usually takes less than 10 minutes.
5 Follow the start up procedure in the chapter on Start Up.
Note: As long as the RH2 is powered, it will automatically drain the cylinder when
there has not been a call for humidity for an extended period of time. This feature will
reduce or prevent the possibility of corrosion of the electrodes and the accumulation
of algae and bacteria growing in the cylinder. The cylinder will remain empty until
there is a call for humidity at which time the fill valve will open and refill the cylinder.
The unit will go through its normal process for optimum operation.
