    5. The HE2 system MUST be connected to a clean, potable mains water supply and it is recommended that the supply pipe work is chlorinated. It is the responsibility of the user to ensure that the water system com- plies with local regulations and bylaws, particularly those for the control of Legionella microbes (such as the HSE ACoP L8, The control of Legionella microbes in water systems).

    Legionnaire’s disease). When designing or installing an air handling system that incorporates “OEM HE2”, appropriate micro-organisms and microbial control methods MUST be consid- ered and this should only be undertaken by suitably qualified persons. A risk assessment MUST also be undertaken in relation to control of micro-organisms and microbial growth, especially Legionnaires disease.

  • Page 6: Delivery And Storage

    1.10 Disposal You must observe local laws and regulations when disposing of your Condair HE2 at the end of its working life. Use personal protective equipment as recommended in the handling section above when handling the evaporative material. In addition, respiratory protection should be worn to avoid inhala- tion of dust or debris from the air flow which may have accumulated on the material.

  • Page 7: Inlet Water - Quality Guide

    It is possible to use high-quality, treated effluent for non-potable applications. The following gives guidance on reclaimed water quality that may be acceptable for use within the HE2. “Effluent treated water”, must be treated by an appropriate water treatment method and risk assessed to ensure it is safe and suitable for use in the unit.
  • Page 8 Note: Adding DISIFIN tablets or other disinfection chemicals will increase the conductivity in the tank. This should be taken into account on systems where a conductivity control system is in use. If you are in any doubt about the suitability of water quality please contact your Condair distributor who will be pleased to support you.
