level requirement of section 21 of this Determination.
Note 1: If the duration of the tank is less than 4 hours, and the portable unitary double duct air conditioner cannot operate without the tank, the product will not comply with the requirements of this Determination.
Note 2: Some portable unitary double duct air conditioners are fitted with a supplementary water evaporation feature designed to provide additional water for the evaporatively‑cooled condenser and/or compressor. They generally require the user to fill the water tank and manually select an operational mode via the unit's control panel or remote control that turns this function on. This operational mode may override other thermostat and fan settings and is designed to achieve higher cooling capacities and greater energy efficiency while this feature is active. When these units deactivate their supplementary water evaporation feature (for instance, when insufficient water is detected in the supplementary water tank), they may automatically revert to cooling without the aid of the supplementary water evaporation feature, or they may automatically switch off.
Note 3: This provision is not applicable to wall mounted unitary double duct air conditioners within product class 1.
Note 4: The testing requirements of this subsection mirror the requirements for unitary single duct air conditioners as detailed in AS/NZS 3823.1.5:2015.
Note 5: AS/NZS 3823.4.1:2014 and AS/NZS 3823.4.2:2014 use the test procedures of AS/NZS 3823.1.1:2012 for unitary double duct air conditioners.
