CONNECTIONS – ELECTRICAL

The power supply to the water heater must not be switched on until the water heater is filled with

water and a satisfactory megger reading is obtained.

All electrical work and permanent wiring must be carried out by a qualified person and in accordance with the

Standards Australia Wiring Rules AS/NZS 3000 and local authority requirements.

The water heater must be directly connected to a 240 V 50 Hz mains power supply. The continuous power

supply to the solar control unit and the timer must be on the same circuit. A weatherproof double pole

isolating switch must be installed adjacent to and accessible from the solar storage tank, in accordance with

AS/NZS 5601.

A flexible 20 mm conduit is required for the electrical cable to the solar storage tank. The conduit is to be

connected to the unit with a 20 mm terminator. Connect the power supply wires directly to the terminal block,

ensuring there are no excess wire loops inside of the cover.

The terminal block on the solar storage tank has two active connections. One active wire (marked “A”) is

required for the operation of the solar control unit and one active wire (marked “TIMER A”) is required for the

operation of the gas boosting system. The gas boosting system is switched by the timer.

Note:

It is essential the active to the solar control unit is not switched by the timer.

The timer is not weatherproof and must be installed indoors. It is recommended the timer be located in

the kitchen or laundry or other location easily seen by the householder.

Connect the hot sensor lead from the solar collectors, through the hole in the side of the air duct, to the hot

sensor cable connector adjacent to the terminal block. Fit the strain relief grommet over the hot sensor lead

and secure at the hole in the air duct.
