10. Safety Messages
Under normal operating conditions:
1. The water temperature from the outlet pipe will not exceed 100°C.
2. When water reaches the pressure relief valve the water temperature will not exceed 93°C.
3. When the water temperature reaches 100°C the input energy would not exceed the energy
released.
The knob can only adjust the temperature to a maximum of 75°C, when the temperature reaches
75°C the power cycles automatically. The heater will also power off when the thermos-limiter
reaches 93°C. If both the knob and the thermos-limiter have failed and the temperature reaches
99°C, the T&P valve will drain away the water.
For inhibition of legionella, every 7 days the following water temperature and times must be held in
the tank.
Remark:
The red light will turn on when the supply voltage is 240V AC / 1000W. In these conditions the water
heater will take 45 minutes to heat the water from 15°C to 75°C and the light will turn off once the
temperature on the temperature knob is reached.
The blue light will turn on when the supply voltage is 12V DC / 300W. In these conditions the water
heater will take 2 hours 15 minutes to heat the water from 15°C to 70°C and then the blue light will
turn off.
Installation shall comply with AS/NZS 3500.4 and any relevant Australian Standards and industry
codes.
