Installation of 6 kW immersion heater
Output selector (6 kW)
Set the water heater’s output selector to the desired output.
Because the immersion heater receives the lowest surface
output at 3 kW, this position should be used first. When a
higher output is required, for example during economy rates,
set the output selector to 6 kW.
