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
Utilize the Drain Cylinder function on page 61
2
Wait until the humidifier is completely drained (20 minutes).
3
Turn the On/Off 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 switch to the On position.
4
Drain the humidifier completely by pressing and releasing the manual drain button. 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 NH-EL 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.
