2.6 Electrical
SIDDONS water heaters are designed for single-phase 220/240V A/C supply only. A certified
electrician must carry out all electrical work in accordance with regulations including AS3000.
A 15-amp circuit breaker should be installed at the power supply for the hot water unit.
A separate circuit breaker is recommended for each unit in the case of multiple installations.
The connection will require an approved, standard 240V 15A On / Off switch or
Junction Box in close proximity to the heater.
Key points:
1) The heat pump should ideally be supplied with a dedicated 240 Volt 15 Amp power supply
2) The heat pump should ideally be connected using a 15 Amp power cable
3) The heat pump power supply circuit must have a grounding wire
4) Power lines and signal lines should be neat and rational, with strong and weak lines
separated so they cannot interfere with each other; leave appropriate distance between
the lines
5) Electrical maintenance must be done by qualified technicians (refer to circuit diagram
below)
6) Unit control panel Code MK4068
7) Fuse specifications: 5A/250V
) The appliance must be installed in accordance with regulations
