DESCALING
Descaling agents cause burns.
Avoid contact with the skin,
eyes and clothes. Wear appro-
priate protective clothing (e.g.
gloves, face mask, apron).
Only approved scale removers
may be used for descaling.
Use Alto Stone-EX, No. 81236
With regular use of Alto
Anti-Stone, descaling will
normally not be necessary.
Incorrect operation of the machi-
ne or the use of non-approved
cleaning agents can cause
deposits in the pipework system.
Scaling is caused by the water
hardness and is indicated by a
gradual increase in the water
pressure displayed on the pressu-
re gauge.
If the working pressure is excee-
ded by 10 bar (with the Vario-
Press trigger gun open), the
system must be descaled.
Procedure:
ð Unscrew the high-pressure
nozzle from the spray lance
and place separately in the
Alto scale remover.
ð Draw in Alto scale remover
via the metering valve by
hanging a cleaning agent
hose into the scale remover
bottle and setting the mete-
ring valve to maximum
concentration.
ð Hold the spray lance in a
separate container to collect
the discharged liquid.
ð Switch on the high-pressure
pump.
ð Actuate the trigger gun. Alto
scale remover is drawn in and
emerges from the spray lance
foaming vigorously after
approx. 1 minute.
ð Switch off the high-pressure
pump and allow the scale
remover to work for approx.
15 minutes.
ð Flush out the pump system
well with clean water.
ð After approx. 2 minutes, a
steady jet of water must
emerge at the water outlet
tube. If this is not the case,
repeat the descaling procedu-
re.
ð Screw the high-pressure
nozzle onto the spray lance.
FROST PROTECTION
If the high-pressure cleaner is
stored in a room in which tempe-
ratures of below 0° C can occur,
antifreeze must first be flushed
through the pump.
During the flushing process,
actuate the trigger gun 2 or 3
times.
In order to avoid any risk, the
machine should preferably be
stored for a short period in a
heated room before it is put into
service again.
