Using the L12
Once operational, the L12 is designed to be simple to use.
8.1 GREEN TOWER LIGHT (and use of trigger)
In normal weeding operation, the green tower light will be
illuminated when the water is of sufficient temperature.
Whenever the user presses the trigger after a release, the
green light must be checked to ensure it is on. This may take
a few seconds depending on the length of release.

trigger pressed and wait for up to 1 minute.

The thermostat indicates the water temperature at the
outlet of the boiler, it can be switched from Celsius to
