SECTION II UNIT OPERATION
Basic Operation
Controlled humidification requires a very precise control sys-
tem. The 6000 utilizes a solid state control to monitor perfor-
mance and maintain humidity. The humidifier evaluates the
operation and alerts the operator to problem conditions and
prevents undesirable operation.
On initial start-up or a call for humidity, the humidifier will at-
tempt to fill to its full load amp rating. The unit will not neces-
sarily have a full cylinder of water. Water level depends on
the conductivity of the water. The more conductive the water,
the more current that can be passed through the same vol-
ume of water.
If the water is not conductive enough to allow the unit to
reach full load amps (full capacity) on the initial fill, the cylin-
der full light will indicate a full cylinder condition. The unit will
operate in this mode with repetitive fill and boil cycles until
the unit has concentrated enough minerals in the water to
reach the rated amp level.
Once full load amp (FLA) has been reached, the fill valve will
shut off. The unit will now compare the rate of change of amp
draw to a time cycle.
If the water in the cylinder is mineral laden and hence very
conductive, a drain cycle will be initiated.
After the drain cycle and/or the time cycle is completed, the
unit will refill and start the process over.
These cycles will repeat until:
•The call for humidity is satisfied.
•The cylinder is used up.
•A fault condition occurs.
On initial start-up, if the water is not conductive enough for
the unit to reach FLA, the water will stop filling when the water
reaches the cylinder full electrode. Once the unit has entered
a cylinder full condition it will operate with fill and boil cycles
only. By eliminating the drain cycle, the water conductivity
will be increased by producing pure steam and leaving the
minerals behind. The increased mineral levels will raise the
conductivity allowing the humidifier to draw sufficient amper-
age to achieve FLA. Normal operation will then commence.
As the electrodes in the cylinder are coated with minerals,
the water level will slowly increase to the cylinder full level.
Concentration will no longer allow the unit to reach FLA. Af-
ter a period of time, the unit will display the red “Service” light
indicating the need to change the cylinder.
