When the microprocessor tells the humidifier to activate, the small green LED
in the upper, left corner of the microprocessor display will light. The humidifier
will begin producing a mist and forcing it into the chamber through the
humidity input barb.
4. The microprocessor will determine the amount of humidification needed to
maintain the desired set-point.
If less than the full capacity of the humidifier is needed, the controller will
provide pulses of power to the unit to limit the output. The humidifier will be
turned on and off cyclically to obtain an average humidity output that is lower
than the full capacity of the Humidifier.
NOTE
To obtain a smooth, even humidity output the Model 518 Cycle Time (CYC.t)
should be set to 1.0 second. Longer cycle times will create longer “gaps”
between humidification pulses. DO NOT SET THE CYCLE TIME LESS
THAN 1.0 SECOND. Shorter pulses may damage the Model 562.
2.1.2.1 Operating Precautions
The Model 562 should operate reliably if the following precautions are
observed:
1. Always run the humidifier directly to the chamber.
Never attempt to combine the humidifier output with another air or
gas source.
2. Always provide a vent on the chamber being humidified.
3. Clean the ultrasonic transducer frequently and thoroughly.
Any dirt or particle build-up on the transducer will stress the
electronics. Once the electronics overheats and stops working, the
humidifier must be replaced. With frequent cleaning, the electronics
should operate reliably for many years.
4. Use distilled or deionized water only.
2.1.2.2 Maintenance & Cleaning
1. Always unplug the humidifier from the Model 518 Chamber before
cleaning.
