Page 10: Location
Location As the heat pump contains flammable refrigerant, ensure the installation location complies with the requirements of AS/NZS 5149. DO NOT install the unit in a location that may be WARNING exposed to combustible gas leaks. If combustible gas accumulates around the unit, it may cause a fire. - Page 11 Noise Ensure that the installation location complies with local noise regulations regarding neighbouring properties. The location must consider noise impact on living areas. Avoid positioning near bedrooms or neighbours bedrooms. Although the running noise level is low it can be expected that the heat pump will run during the night. The timer function can be used to limit operating hours if noise is a concern.

Page 13: Connections And Plumbing Arrangement
Connections and plumbing arrangement The cylinder component of the system must be installed in accordance with G12/AS1, and AS/NZS 3500.4:2018. For service and maintenance, please allow sufficient room for access to covers and valves. All hot water pipe work should be insulated with polythene foam or equivalent insulation to optimise performance and energy efficiency. - Page 14 TPR valve (850 kPa, 99 °C, 10 kW) The supplied TPR valve must be installed to ensure safe operation. Failure to do so can potentially cause injury and damage the unit. The TPR valve should be connected to a vertical discharge pipe that enables water to flow downwards at all times.

Page 16: Storage And Delivery Temperatures
Storage and delivery temperatures Storage temperature To meet the New Zealand Building Code requirement to disinfect water for legionella bacteria, the system has been set to ‘Standard’ mode, continually heating the water, using the heat pump, to 60 °C. If the system operates as a normal electric tank (in element only mode), the factory thermostat preset temperature is 70 °C, with a range of 65-75 °C. -
Page 17: Water Quality
Water quality Water chemistry has a direct impact on hot water heaters, affecting corrosion protection measures, or causing scale buildup. Water quality MUST: 1. Meet the Water Services (Drinking Water Standards for New Zealand) Regulations 2022, or the relevant Drinking Water Standard at the time; AND 2. -
Page 18: Electrical Supply And Connections
Electrical supply and connections The electrical connection must be carried out by a qualified person in accordance with the latest version of AS/NZS 3000 Wiring Rules. It MUST have the supply terminals connected to an independent, fused AC 230 V 50 Hz power supply with an isolating switch installed at the switch board, which shall effectively isolate all active supply conductors from the circuit. - Page 19 This page intentionally blank...
