12  Specific requirements for unitary double duct air conditioners
 (1) This section applies in relation to all tests undertaken for the purposes of Part 3, Part 4 and Part 5 of this Determination.
Specific requirements for wall mounted unitary double duct air conditioners
 (2) Wall mounted unitary double duct air conditioners must use the test procedures of AS/NZS 3823.1.1:2012. They must be installed on the wall of the test chamber as per the manufacturer's installation instructions.
Specific requirements for portable unitary double duct air conditioners
 (3) Portable unitary double duct air conditioners must use the general test procedures of AS/NZS 3823.1.1:2012. However, both the exhaust and inlet ducts must be installed as per Appendices A2.1 to A2.5 of AS/NZS 3823.1.5:2015.
 (4) Portable unitary double duct air conditioners that contain a condensate container must not have a test interrupted by a full condensate container triggering a cut-off switch. If necessary, condensate containers must be modified to drain away excess condensate into a larger container in the test chamber before the volume that activates the cut-off switch is reached.
Note 1: Some portable unitary double duct air conditioners may have an in-built hose to facilitate the draining of condensate.
Note 2: Some portable unitary double duct air conditioners are designed to collect condensate and evaporate it on the condenser. This process should be allowed to occur during testing.
Note 3: The testing requirements of this subsection mirror the requirements for unitary single duct air conditioners as detailed in AS/NZS 3823.1.5:2015.
 (5) For a portable unitary double duct air conditioner that contains a supplementary water tank:
 (a) the duration of the tank must be determined during the standard cooling full capacity test; and
 (b) in determining this period:
 (i) the test setup and test conditions must be as per AS/NZS 3823.1.1:2012; but
 (ii) the duration must be determined as per Appendix B of AS/NZS 3823.1.5:2015; and
 (c) if the duration of the tank is  4 hours:
 (i) all tests may be performed using this feature as per the manufacturer's instructions; and
 (ii) if tests are performed using the tank—any water added to the tank must be 27°C ± 1°C; and
 (iii) if the product can operate both with and without the tank—the standard cooling full capacity must be determined both with and without the tank being used; and
 (d) if the duration of the tank is  4 hours—the tank must not be used when determining whether the product meets the GEMS 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
