Preventative Maintenance
Humidification System
The humidification system utilizes an ultrasonic transducer that has an estimated lifespan of 3000
hours after which it may need to be replaced. The ultrasonic transducer is not user replaceable.
Please contact ETS for assistance with repair/replacement. To maximize the life of the transducer,
utilize an appropriate water supply (deionized water or distilled water) and perform regular
preventative maintenance after every
300 hours
of operational use.
