5.4.1 Activating the steam outlet function:
⇒ Remove the handpiece from the handpiece holder�
⇒ Press the steam button (8) and hold down�
⇒
Briefly press the ON / OFF button (3).
♦ The "Heating / Ready for operation" indicator (5) flashes
green�
♦ The solenoid valve is opened, and steam is released through
the steam nozzle�
♦ The heating is switched off.
⇒
The steam button can be released�
⇒
Hold the handpiece in your hand or place it aside in a safe place
so that the steam can escape without any risk (e�g�, in a sink)�
If steam is used for extended periods, the handpiece and the steam hose can become extremely
hot!
The unit's steam outlet function remains active until it is switched off by pressing the steam but -
ton or the ON / OFF button.
5.4.2 Switching off the steam outlet function:
Wait until the pressure has been fully released before switching off the steam outlet function.
⇒ Briefly press the steam button or the ON / OFF button.
♦ The solenoid valve is closed�
♦ The "Heating / Ready for operation" indicator (5, Fig. 12) is off.
♦ The unit is OFF�
⇒ Open the tank cap�
⇒
Allow the unit to cool down before further cleaning or maintenance work�
Once the steam outlet function has been switched off, open the tank cap to prevent pressure
building again in the pressure tank due to residual heat.
5.5 Calcification indicator
In the case of continuous operation with drinking water, dirt collects in the pres-
sure tank as well as calcium deposits as a result of the hardness of the water�
These either form as a crust on the walls of the pressure tank or pieces of crust
break off and settle at the bottom of the tank.
This reduces the energy efficiency of the heating.
In a salt-based softening system, calcium and magnesium are exchanged
for sodium in an ion exchanger. The sodium bonds do not form on the
walls of the pressure tank, however they do remain, for the most part, in
the pressure tank.
Here they form a sort of sludge in the water in combination with other suspended solids, which
contaminates the pressure tank and is also detected by the calcification indicator.
That's why the calcification indicator is also activated when a softening system is used.
In this case, the pressure tank must be rinsed thoroughly, see Chap. 6.3.
The control detects the increasing calcification in the pressure tank. If the calcification exceeds a pre -
defined level, this is signaled as follows:
♦ An acoustic signal sounds�
♦ The "Calcification state" indicator (6) flashes.
⇒ Rinse / descale the pressure tank at the next opportunity, for example at the end of the week (see
Chap. 6.3 / 6.4).
The calcification level is not saved. Instead, it is determined again every time the unit is switched on and
heated up�
How quickly a pressure tank becomes calcified and how this affects the energy efficiency of the
heating system depends on a variety of parameters, not all of which can be taken into consider-
ation by the calcification indicator.
For this reason, descaling must be carried out every three months at the latest regardless of the
calcification indicator.
