    Requirements" on page 27 for 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 warranty. In order to operate the equipment in the intended manner all information contained in this manual, in particular the safety instructions, must be observed closely.
  • Page 11 Safety Precautions that Must be Observed DANGER! Risk of electric shock! The unit is mains powered. Using the On/Off switch on the humidifier to shut down the unit will NOT shut off power to the control cabinet. Live parts may be exposed when the access panels or doors are removed.
  • Page 12 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 separating the electrical cabinet).

  • Page 13: 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.

    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;...

    Treated water enters the humidifier's reservoir from an inlet located at the bottom of the unit. The water that enters the humidifier's reservoir must be treated to remove minerals, bacteria and fungi, and should otherwise be pure to prolong the service cycle of the unit and, above all, safeguard the public. An accumulation of minerals will result in scale, and an accumulation of bacteria and fungi will result in unhygienic conditions in the space.

  • Page 33: Best Practices

    7.6.1 Remote Ultrasonic Blower Pack Installation Use Condair flexible tubes that are provided by your Condair representative. Mist connection materials from another manufacturer may adversely affect the operation of the unit. The length of the mist line should be kept as short as possible. It should not exceed the maximum equivalent length of 2 m (6.56 ft).
  • Page 34 This should be performed manually or through changing the demand signal (full demand to mist; zero stop mist and allow to drain). Condair provides a cleaning and disinfecting kit for the Ultrasonic Humidifier (P/N: 2594996) IMPORTANT! Avoid cleaning with hard or rough materials, such as steel wool, or metal brushes. Abrasions on the surface of any components may prevent micro-organisms from being cleaned easily.
