If the steam switch is pushed on the gun, the solenoid
valve opens and the steam flows from the pressure tank
through the plug forward to the steam gun.
With the control valve steam volume the steam volume can
be adjusted.
In addition, hot water can be mixed into the steam by
means of the VAPOHYDRO control valve.
If the valve is opened, water rises in the riser and mixes
with the steam at the solenoid valve.
This way, the moisture of the steam can be regulated from
dry steam (valve closed) to hot water jet (valve completely
opened).
After approx. 50 operating hours, the indicator light Desca-
ling lights up (white).
This in an indication that the pressure tank must be
descaled now at the latest.
To do so, completely dissolve the pouch contents of RM
511 in 1 litre of warm water.
Fill this solution into the pressure tank and allow to react
for approximately 8 hours.
During this time, the pressure tank must remain open and
must not be used.
After pouring out the solution, rinse the pressure tank with
cold water at least twice in order to remove all residue.
Press the reset key until the indicator lamp "Descaling"
goes off.
The appliance is ready for use again. After approx. 50 op-
erating hours, the indicator lamp "Descaling" shows the
next necessary descaling process.
The thermostat water shortage interrupts the circuit for the
heating if the water in the pressure tank is consumed and
the temperature rises further.
Red low-water indicator lamp lights up
When the temperature falls again, the water shortage ther-
mostat automatically closes the circuit again and the indi-
cator light goes out.
The thermostat is an additional safety element.
It interrupts the circuit for the heating if the thermostat wa-
ter shortage is defective and the temperature has risen fur-
ther.
If the thermostat has tripped, it will not switch back auto-
matically.
The device must be opened in order to find out why the wa-
ter shortage thermostat has not worked.
After detection and elimination of the error, the pin on the
thermostat must be pushed in again.
