Humidifier
Some units are provided with a self-contained, microprocessor-controlled steam generator type
humidifier as standard equipment and others, as an option. The steam generating humidifier
uses a disposable cylinder with electronic controls. The humidifier discharges pure steam with
no material dust carry-over and has a self-regulating automatic flush cycle. Cylinders are
disposable and do not requiring cleaning or maintenance. The humidifier fill level, water
conductivity and flush rate automatically adapt, both in frequency and duration, to variations in
the incoming water. The humidifier assembly is capacity field-adjustable and includes a high-
water probe. Drain duration and drain interval are also field-adjust
able. See the manufacturer’s
literature for more detailed information on field adjustments.
9.6.1. Humidifier Canisters
The humidifier has been designed to require very little maintenance. Regular maintenance
consists of checking the humidifier to insure it is in good condition, replacing the cylinder when
the software advises that the cylinder is spent and cleaning out the drain valve whenever the
cylinder is replaced. The frequency of change will depend on usage and water type. A set of
the humidifier manufacturer’s instructions is included with the paperwork placed inside the unit
when it ships.
9.6.1.1.
Cylinder Spent Fault
After an extended period of operation, the cylinder is completely spent the MES2 will stop
operating and the yellow LED will flash in a repeating pattern of 4 flashes. At this time the
cylinder must be replaced. The steam cylinder is disposable and must be replaced at end of
cylinder life. Cylinder life is dependent on water supply conditions and humidifier usage. Failure
to replace the cylinder at the end of cylinder life will result in improper operation and may result
in damage to the humidifier. Data Aire is not responsible for any damages resulting from, or
attributed to, the failure to replace a spent cylinder. Data Aire recommends keeping a
replacement cylinder in stock throughout the humidification season. This will prevent possible
downtime when the humidifier reports cylinder end of life.
9.6.1.2.
Replacement Cylinder
The label on the existing cylinder identifies the cylinder type in its top left corner. When ordering
a cylinder always quote the three- or five-digit model number on the label, the humidifi
er’s serial
number, and the humidifiers voltage. Serial number and voltage are located on the specification
label on the left side of the humidifier. Contact Data Aire Parts Department for replacement
humidifier cylinder.
9.6.1.3.
Removing the Cylinder
•
Check to see if yellow service light is flashing meaning cylinder replacement is necessary.
•
Turn OFF the water supply to humidifier.
•
The old cylinder must be drained completely before removing. This is done by pushing the
On/Off/Drain switc
h to the “Drain” position.
•
Let the humidifier drain until no more water is flowing out to drain (usually not more than 10
minutes).
