Heat exchanger - to be cleaned once a year, with high pressure, through front side and rear-side clean-out hole.
Take dripping water hose out of the water tank.
Tank - to be emptied and cleaned.

Decalcification
Has to be performed regularly/periodically. Calcification is dependent from the water hardness as such, and is
indicated at the pressure gauge by a gradual increase of the water pressure. Decalcification has to be made once
the working pressure increases by 10 bar.
For decalcifying, please proceed as follows:
Open water-tap, unscrew high pressure nozzle from spray lance and dip/put it seperately into the decalcifying
agent.
Unscrew high pressure hose from water outlet tube. Put cleaning and care agents intake hose into the filled
decalcifying agent bin. Open dosing valve completely.
Start drive motor. The decalcifying agent is taken in and, after approx. 1 minute, it 'bubbles' out of the water
outlet tube (strong bubbling effect). Stop drive motor. Then take out cleaning and care agents intake hose from
the bin ontaining decalcifying agent, and put it into clear water.
After about 15 minutes, start drive motor. After about 2 further minutes, a uniform jet is to emerge from the
water outlet tube. Should this not be the case, then decalcify once again.
Screw high pressure nozzle onto the spray lance and re-connect the high pressure hose.
Caution!
The decalcifying agent causes burns. Avoid contact with eyes, skin, and clothing. Wear the prprer protective
clothing (for example gloves, facial protection, apron).
The machine is subject to the German Steam Boiler Decree, in accordance to which only such agents are to be
used which are officially admitted, as is, for example, the Wap decalcifying agent.
