Standby Mode
During the standby-mode the water in the steam generator tank is kept hot. This minimizes the time to produce steam when
generator goes to on-mode next time.
Standby-mode can be activated by any of the following methods when the unit is in on-mode:
1. Short press “Standby” button
2. Short press “Power” button
3. When session time expires.
In standby-mode text “Standby” is displayed altering with the remaining standby time. To change remaining time press “up”
or “down” arrow buttons. If the time is changed during the first 5 minutes after the activation of standby-mode, the time will
be saved as a new default standby time.
To activate on-mode again short press the “standby” button.
To go off-mode:
1. Press “Power” button for more than 3 seconds.
2. Press “Standby” button for more than 3 seconds to activate autodrain process, after which the unit goes automatically off-
mode. (If autodrain feature is not available the unit will go off-mode)
3. Wait until remaining standby time expires and autodrain process (if available) completes.
Auto drain Mode
The auto drain feature automatically drains the water system after every use. The tank is flushed and will remain empty until
the steam generator is used again.
After the Standby time runs out, control unit automatically goes to Autodrain mode. When the drain cycle is activated, the
generator’s tank will be filled first. The water inside the tank will be cooled down, so the valve can be opened, as the water is
not boiling hot anymore.
The draining process will take about 10 minutes.
User can cancel auto drain process whenever the water level in the tank is at normal or below normal level by pressing “power”
button for more than 3 seconds.
To start Auto Drain in “On” mode press “Power” or “Standby” button followed by a long press (more than 3 seconds) of “Stand-
by” button.
The maximum draining process will take about 10 minutes.
