 Turn the main switch to position “0”.
 Shut off water supply.
 Unscrew the water inlet hose and high
pressure hose from the appliance.
 Unscrew closing stopper on the bottom
of the boiler and empty the boiler.
 Let the high-pressure pump run for
max. of 1 minute, until the pump and
pipes are empty.
The machine should be stored in frost-free
rooms. In case there is frosting risk, for e.g.
if the machine is installed in open areas,
then the machine must first be emptied and
flushed using an anti-freezing agent.
ṇ
Warning
Frost will destroy the not completely water
drained device.

Drain water.
 Flush device with anti-freeze agent.
A certain corrosion protection is
achieved with this as well.
Caution
Risk of injury and damage! Observe the
weight of the appliance when you transport it.
When transporting in vehicles, secure the
appliance according to the guidelines from
slipping and tipping over.
Caution

rior rooms.
ƽ
Danger
Risk of injury! The main switch is to be
switched off while carrying out any repairs
or maintenance jobs.
 Check the connection cables.
The connection cable must not be dam-
aged (risk of electrical shock). A dam-
aged connection cable must be
replaced immediately by an authorised
Customer Service Engineer or an elec-
trician.
 Check hot water hose.
The hot water hose must not be dam-
aged. A damaged hose must be re-
placed immediately (danger of burns).
Calcified appliances worsen the heat trans-
fer and the efficiency is reduced.
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.

 Fill the boiler with 30 liters of water.
 Connect the water hose directly to the
water input and hang in the other free
end into the container.
 Unscrew the nozzle of the steel pipe.
Also insert the connected spray pipe of
the high-pressure cleaner into the con-
tainer. This is how a cycle is created:
Container - pump - boiler.
 Pour 2 l of decalcifying solution into the
container.
 Let high-pressure pump run.
 The solution must not become hotter
than 60 °C. Ensure that there are no
steam bubbles (do not mistake them for
foam).
 If there is no visible gas generation after
15 minutes, pour another 0.5 l of decal-
cifying solution into the container (max.
concentration 7%). With regular decal-
cifying, this will only take approx. 3 min-
utes.
