tested and approv approved boiler decrust-
ing agents may be used.
–
RM 100 (Order No. 6.287-008) dis-
solves chalk and simple compounds of
chalk and detergents residues.
–
RM 101 (Order No. 6.287-013) dis-
solves the deposits that cannot be dis-
solved using RM 100.
 Fill a 20 litre container with 15 l water.
 Add one litre of boiler decrusting agent.
 Connect the water hose directly to the
pump and hang in the other free end
into the container.
 Insert the connected spray pipe without
nozzle into the container.
 Start the engine according to the oper-
ating instructions of the engine manu-
facturer.
 Open the hand-spray gun and do not
close it during the decalcification pro-
cess.

Set the appliance switch to a working
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.
Caution
Risk of damage! Freezing water in the ap-
pliance can destroy parts of the appliance.
–
Store the appliance in a heated room
during winter or empty it. During longer
breaks in operation, it is advisable to
pump in anti-frost agents into the appli-
ance.
–
If it is not possible to store frost free,
shut down device.
 Drain water:
 Screw off water supply hose and high
pressure hose.

Screw off supply hose at boiler bottom
and drain heating spiral empty.
