Open the hand-spray gun and do not
close it during the decalcification proc-
ess.
Set the temperature regulator to work-
ing temperature of 40 °C.
Let the appliance run till the working
temperature is reached.
Switch off the appliance and let it stand
for 20 minutes. The hand-spray gun
must remain opened.
Then pump out the machine until emp-
ty.
Note: As an anti-corrosion measure and for
neutralising the acid residue, we recom-
mend that you finally pump an alkaline so-
lution through the machine (for e.g. RM 81)
via the detergent tank.
