    Blower Pack within specified operating conditions. Refer to "Technical Data" on page 19 details. Any other type of application, without the express written consent of Condair, is considered to be NOT conforming to its intended purpose, and may lead to dangerous operation and will void the war- ranty.
  • Page 10 CAUTION! Electrostatic discharge (ESD)! The electronic components inside the control cabinet in the humidifier are sensitive to elec- trostatic discharge (ESD). Prevention: Take appropriate measures to protect the electronic components inside the unit against damage caused by electrostatic discharge (ESD). Refer to ANSI/ESD-S20.20. WARNING! Heavy object.
  • Page 11 Modifications to the Unit Prohibited Modifications are NOT permitted on the Ultrasonic Humidifier without the express written consent of Condair. Safety Labels The safety label (hygiene) is found on the right wall inside the plumbing cabinet (on the panel sep- arating the electrical cabinet).

  • Page 12: Hygiene

    There are multiple points in the humidification system where a contamination can occur. It is the responsibility of the customer and of Condair to ensure that health hazards due to contamination are reduced to acceptable levels. The use of a hygiene risk assessor is recommended.

    Repair and fault finding. Training and guidance. Note: * Condair uses a quick method for measuring bacterial activity in the water with the use of BactiQuant (BQ). Once the water sample has been taken, the bacteriological quality of the water is read within 30 minutes, and the Condair service team will disinfect the system if necessary.

  • Page 15: Product Description

    Product Description General Description The Ultrasonic Humidifier is a steam-less humidifier. To humidify the space, the Ultrasonic Humidifier creates mist using piezoelectric transducers. Mist is expelled from the unit with internal fans, and an Ultrasonic Blower Pack (if installed), into the space. Mist is then absorbed into the air. The Ultrasonic Blower Pack comes in 4 different output capacities;...

Functional Description The Ultrasonic Humidifier is an adiabatic unit that uses transducers in the humidifier's water reservoir to create a fine mist using high-frequency vibrations (1.7 MHz).
  • Page 18 Air Supply Air supplied to the humidifier comes from the space surrounding the humidifier and through the humid- ifier. The air should be filtered and clean to prevent contaminating the mist with microorganisms and dust. The use of the supplied air filters (recommended) is advised for the Ultrasonic Humidifier and Ultrasonic Blower Pack.
