Operation

Operating elements
1 Indicator lamp (green) - heater on
2 Switch for manual/automatic operation
3 Indicator lamp (red) - fill level of liquid
softener
4 Main switch
5 Control board
Turning on the Appliance
1 Temperature limiter
2 Temperature controller
 Open the water supply.
 Set temperature regulator to desired
temperature.
 Turn the main switch to position "1".
 Set switch to manual or automatic oper-
ation.
We recommend the following cleaning tem-
peratures:
– Light contaminations
30-50 °C
– Contaminations containing protein, i.e.
in the food processing industry
max. 60 °C
– Vehicle cleaning, machine cleaning
60 -85 °C
Note: If the working pressure and the flow
rate are changed, the water temperature
will change as well.
Turn off the appliance
 Turn switch for manual/automatic oper-
ation to position "0".

Shutting down

 Turn the main switch to position "0".
Emptying the appliance
 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.
Frost protection
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.
ATTENTION
Risk of damage! 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.

Transport

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 guide-
lines from slipping and tipping over.

Storage

CAUTION
Risk of injury and damage! Note the weight
of the appliance in case of storage.
This appliance must only be stored in inte-
rior rooms.

Care and maintenance

DANGER
Risk of injury! The main switch is to be
switched off while carrying out any repairs
or maintenance jobs.
Visual check
 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).
Decalcify boiler.
Calcified appliances worsen the heat trans-
fer and the efficiency is reduced.
DANGER
Risk of explosion due to combustible gas-
es! Smoking strictly prohibited during de-
calcification. 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 approved boiler decrusting
agents may be used.
– RM 100 (Order No. 6.287-008) dis-
solves chalk and simple compounds of
chalk and detergents residues.
 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.
