You can enter into a maintenance contract with the concerned
Kaercher Sales Office for the machine.
Always store the inspection card at the plant and enter all the
maintenance/service jobs that have been carried out.
Calcium deposits can lead to:
–
higher pipe resistances
–
poor thermal conductivity values
–
even to failure of the components with heavy calcium depos-
its
Danger
Risk of explosion due to combustible gases! Smoking strictly pro-
hibited during decalcification. Ensure proper ventilation.
Danger
Risk of burns injury on account of acid! Wear protective glasses
and protective gloves.
According to statutory requirements, only tested and approv ap-
proved boiler decrusting agents may be used.

RM 100 (Order No. 6.287-008) dissolves chalk and simple
compounds of chalk and detergents residues.
–
RM 101 (Order No. 6.287-013) dissolves the deposits that
cannot be dissolved using RM 100.
In case of Kärcher HD-C(E) pump module, separate the cool-
ing water inlet from the swimmer tank.
HD-C: Fill the swimmer tank up to 3/4 level with water.
HD-E: Fill the 70-100 liter container up to 3/4 level with water.
Establish a connection between the container and the sution
side of the pump.
Guide the outlet HWE 4000 through a filter back into the con-
tainer (in case of spray jet operations, the spray pipe can be
inserted into the container without the nozzle).
Add decalcifying agent to the container; while doing so follow
the concentration recommended by the manufacturer (nor-
mally indicated on the lable).
Turn the selection switch of the remote control to "Temperatur
kalt". The thermostat "hot water“ will be deactivated.
Start the plant and circulate the solution through pumping for
approx. 20 minutes. Ensure that there are no steam bubbles
(do not mix it up with foam!)
Pump out until the plant is empty.
Note:
As an anti-corrosion measure and for neutralising the acid
residue, we recommend that you finally pump an alkaline solution
through the machine (for e.g. RM 81) via the detergent tank.
Note:
Follow the local regulations for disposing of the used mix-
ture of the decalcifying agent.
Turn off fuel tap (1).
Loosen the locking screw (3).
Remove the casing (4).
Clean the filter inlay (2) with compressed air.
Assemble it back in the reverse sequence.
