  • Page 7: For Your Safety

    Furthermore, for safety and warranty reasons, interventions may only be undertaken by specialist per- sonnel authorised by Condair. It is assumed that all persons entrusted to work on the Condair MD are familiar with and abide by the regulations on occupational health and safety and accident prevention.
  • Page 8 For this reason: Once the Condair MD has been commissioned for the first time, it must no longer be switched off and must be operated either in "humidifier mode" or in "standby mode". This will ensure that the water system is purged at regular intervals, and any contamination is counteracted.
