CAREFUL
Risk of injury!
Injuries caused by acidic steam!

•
The material of the pressure vessel can be
damaged by chemicals!
•
Only utilise potable water or DI water (1.5 l with 3%
pure citric acid) for descaling!
Figure 8.2: Flushing set for connecting to the water tap (3/4")
•
Allow the unit to cool down until it is depressurised (0 bar). After
completion of the pressure discharge, the device still needs to
cool down for approx. 5 minutes to avoid spontaneous
formation of steam when flushing.
•
Place the flushing set (Figure 8.2) and the maintenance hose
from the scope of delivery in a position ready for use.
WARNING
Hot steams / Hot liquids
Risk of scalding from steam!
•
Only open the pressure vessel screw cap when the
device is depressurised!
•
Allow the pressure vessel to cool down before
opening the pressure vessel screw cap!
•
Observe the gauge display (Figure 8.2)! The
device remains under pressure as long as one
segment is illuminated on the value scale on the
gauge.
•
The residual water may be hot!
•
Wear heat resistant gloves when handling the hose
1. Open pressure tank screw cap (Chapter 6.2 Filling the
device).
2. Connect the maintenance hose (Figure 8.2.1) to the
connecting mounting on the ball valve.
3. Position the device in such a way that the maintenance hose
hangs into a sink or bucket large enough for this operation and
that the ball valve can be operated.
