This Standard specifies minimum requirements for the operation and maintenance of air-handling and water systems of buildings, other than sole occupancy dwellings. It does not include refrigerated room air-conditioners and non-ducted split systems.NOTES:1 In the event of an outbreak of Legionnaires' disease, special action is necessary. This will be advised by the health authorities.2 Further information on the control of microbial growth in air-handling and water systems of buildings is given in SAA/SNZ HB32.3 Design, installation and commissioning requirements are given in AS/NZS 3666.1.
