ANTI-LEGIONELLA TIMER

The Inoxstor contains an anti-legionella timer which automatically boosts the tank temperature periodically using the
inbuilt immersion heater in order to prevent the growth of legionella bacteria.
Once power is applied to the Inoxstor, it will wait a pre-defined time and then activate the immersion heater for a specific
duration. The timer comes pre-set from the factory to provide 4 hours of legionella control every 10 days. When the timer
activates, the high limit thermostat in the immersion heater will prevent excessive temperatures from being reached in the
Inoxstor.
The factory settings may be altered, however in all cases observe the following:
▪ The setting of the high limit thermostat setting on the Immersion should not be reduced below 60C.
▪ Take care when setting the high limit thermostat above 60°C. A thermostatic mixing valve MUST be installed and should
be tested to ensure excessive temperatures do not reach the taps and showers.
▪ Do not reduce the heating period of the anti-legionella timer below 4 hours.
To set the interval, rotate the small grey screw C. The time shown in the indicator window will rotate
between 10s, 1m, 10m, 1h, 10h, 1d and 10d. Select the next higher period than the interval you re-
quire. For example, for 7 days, choose 10d.
To Fine-tune the interval, turn the orange screw D which indicates 10ths. In the example above, it
should point to 7, which is 7/10ths of 10d. To select 2 days, it should be turned to 2. To select 10
days, it should be turned to 10.
To set the active duration, rotate the small grey screw A. Select the next higher period than the
duration you require. For example, for 2 hours, choose 10h.
To Fine-tune the duration, turn the orange screw D which indicates 10ths. In the example above, it
should point to 4, which is 4/10ths of 10h. To select 5 hours, it should be turned to 5. To select 10
hours, it should be turned to 10.
LED Un will flash while the timer is waiting. LED R will turn on when the timer activates the immersion.
