Danger
Risk of injury!

Check the high pressure hose for dam-
ages (risk of bursting).
Please arrange for the immediate ex-
change of a damaged high-pressure hose.
The flow resistance is higher if there are de-
posits in the pipes; this increases the load
on the motor.
ƽ
Danger
Risk of explosion due to combustible gas-
es! Smoking strictly prohibited during de-
calcification. Ensure proper ventilation.
ƽ
Danger
Risk of burns injury on account of acid!
Wear protective glasses and protective
gloves.
According to statutory requirements, only
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 proc-
ess.
 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 neu-
tralising the acid residue, we recommend
that you finally pump an alkaline solution
through the machine (for e.g. RM 81) via
the detergent tank.

Warning
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.
 Screw off water supply hose and high
pressure hose.
 Screw off supply hose at boiler bottom
and drain heating spiral empty.
 Operate device for max. 1 minute until
the pump and conduits are empty.
Note
Observe handling instructions of the anti-
freeze agent manufacturer.

Fill anti-freeze agent of the trade into
swimmer container.
 Switch on appliance (without heater) till
the appliance has been completely
rinsed.
A certain corrosion protection is achieved
with this as well.
