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 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.
