HUMIDIFIRST
MAINTENANCE
Basic Maintenance
Maintenance of Humidifirst Ultrasonic humidifiers is very simple and plays an important
part in keeping the humidifier modules operating properly and extending the life of the
components inside. No later than one month after start-up, the humidifier modules
should be drained and cleaned. After that they should be cleaned a minimum of once a
year, depending upon the cleanliness of the air and water going through them. The
procedure for cleaning the humidifier modules is as follows:
1.
Make sure that the power supply is disconnected.
2.
The humidifier modules should be completely drained and the mist diffuser
removed.
3.
The humidifier basin and transducers should be cleaned thoroughly with a weak
vinegar and water solution. Never scrape the transducer surfaces or use
abrasive cleaners as this may cause damage. Typical kitchen cleaners can be
used but make sure that the cleaner does not advertise a “shining” agent. Shining
agents can leave a film on the transducers, which will reduce the mist output.
4.
The basin should be rinsed completely.
5.
The mist diffuser should be cleaned and rinsed before it is replaced.
Disconnect the power cord to the Master control panel and check all the wiring
connections for tightness. This should be checked a minimum of two times per year.
Transducers
The transducers and the printed circuit driver board produce the mist. The normal life of
a transducer can differ depending upon several variables. Typically, the operating life of
the transducer is around 10,000 hours. See “Basic Maintenance” above for cleaning
directions. The following variables will affect the life of the transducer.
1.
The mineral content of the water affects the length of the transducer life. The
cleaner the water, the longer the transducers will last.
2.
High entering water temperature will cause premature failure of the transducers.
3.
High entering air temperature (above 122 ° F) may cause premature failure of the
transducers.
4.
Excessively dirty air can soil the transducers and reduce the transducer output.
Caked on debris could cause overheating of the transducers and eventual failure.
5.
Poor water pressure may not allow proper water flow into the humidifier basin.
A water level in the basin of less than 1 ½” may cause the water to become hot
and therefore cause transducer failure.
