The power supply to the water heater must not be switched on until the solar storage tank is filled with
water.
MEGGER READING
It is not mandatory to conduct a megger test on a plug in appliance, however if a megger test is conducted on
this water heater, then the following should be noted.
Warning: This water heater contains electronic equipment and 500 V insulation tests must only be
conducted between either active and earth or neutral and earth. An active to neutral test WILL damage the
electronics.
An insulation test result of approximately 660 KΩ for this water heater is normal.
AS/NZS 3000 permits an insulation test result less than 1 MΩ where the appliance is approved to a Standard
applicable to the appliance.
This model water heater is categorised as a 'stationary Class 1 motor operated appliance' and satisfies the
requirements of AS/NZS 60335.1 for leakage current and electric strength. Therefore, this model water heater
complies with the insulation resistance requirements of AS/NZS 3000.
ELECTRICAL CONNECTION
All electrical work and permanent wiring must be carried out by a qualified person and in accordance with the
Wiring Rules AS/NZS 3000 and all local codes and regulatory authority requirements.
Warning: Temperature controllers or an EZiSET kit must not be fitted to the in-series booster as part of a
solar water heater system because water at a temperature much higher than the controller or EZiSET setting
can be delivered.
The water heater requires a 240 V AC, 50 Hz mains power supply for operation. The solar storage tank and
in-series gas booster are each supplied with a 1.8 metre power cord to operate the solar control unit and gas
booster. Two switched general purpose outlets (GPO) are required to be located within 1.2 metres of the
installation. The GPOs must have a continuous power supply. The GPOs are required to be weatherproof if
installed outdoors.
The power consumption of the water heater is:
Component
Solar controller
Solar pump
Gas booster
The water heater will only operate on a sine wave at 50 Hz. Devices generating a square wave cannot be used
to supply power to the water heater.
