9.0 Electrical requirements This section covers electrical requirements for heat pump installations. It is an essential element of the installation that all electrical work is carried out in an appropriate manner to ensure that the installation is safe and complies with legislation. All electrical wiring must have a Certificate of Compliance (CoC) certificate issued by a registered tradesperson on completion and inspection of the installation. Electrical work must be carried out in accordance with the Electricity Act, electrical wiring regulations and AS/NZS 3000:2007. Inverter units with a heat output of 5 kW or greater must be connected to a separate circuit. Those under 5 kW may be connected to a power circuit of at least 2.5 mm twin and Earth cabling with a 20 amp lockable RCD, and where sufficient load is safely available (i.e. not a kitchen, laundry or other heavy load circuit). 9.1 Installing electrical wiring • Select a circuit for the main power supply. • For new work, use a dedicated supply. • Refer to the manufacturer’s specifications for: – rated voltage – input capacity/fuse size – electrical cable size – wiring diagram for electrical installation. • All hard wiring must be carried out by a registered electrician. 9.2 Outdoor unit connections Figure 9.1 Connect power supply cable to terminal block • Remove service cover from outdoor unit. • Fix indoor/outdoor connecting cable correctly to the terminal block in the outdoor unit. • Tighten terminal screws to ensure that wires are firmly secured. • Connect power supply cable to terminal block in outdoor unit (Figure 9.1). • Install a lockable isolating switch with a minimum 3 mm gap when open (Figures 9.2 – 9.4). • Install the switch so that it can be reached for servicing.
