TEMPERATURE PROTECTION
There are two temperature protections in the unit that can be accessed from the outside.
These can be found at the left and right side of the appliance (fig. 1-8 & 1-12). The protection at the left (fig. 1-8)
belongs to the flow water heater, the right one (fig. 1-12) belongs to the hot water system. These protections
switch off the corresponding parts when the temperatures rise too high. The most common cause for switching off
is scale that has not been removed in time. If the temperature protection operates proceed as follows:
1.
Let the unit cool down.
2.
Unscrew the black protection cover.
3.
Push the button that now appears and replace the black cover tightly.
When the protection was triggered due to scale formation, then proceed according to section 7.2.
When scale formation was not the cause, then contact your dealer.
9.
TRANSPORT
If the machine has to be transported, the water reservoirs must be emptied.
1.
Switch the appliance off and remove the plug from the wall socket.
2.
Remove the plugs from the containers and remove the containers.
3.
Close the water outlet tap and disconnect the supply and overflow hoses.
4.
Take the drain hose tap (fig. 1-13) out of the underside of the base plate, to drain the flow heater system
completely, then close it off again. (Attention: the water can still be hot!).
5.
Take the drain hose tap (fig. 1-14) out of the underside of the base plate, to drain the hot water reservoir
completely, then close it off again. (Attention: the water can still be hot!).
