Unpacking

– Check the contents of the pack before
unpacking.
– In case of transport damage inform ven-
dor immediately.
– Store the drilling template on the carton
to assemble the device.
Installation
Note:
The water connection, the high pressure
network as well as the electrical connection
can only be carried out by authorised ex-
perts in accordance with local regulations.
– The installion should be set-up in a dry,
non-explosive environment.
– The installion should be installed on
firm and even ground.
– The installion should be easily accessi-
ble for maintenance work.
The following are required for installation:
– Wall mount
– Installation with the mounting kit floor
rack (optional)
Fasten the device to the wall
CAUTION
Risk of personal injury or damage! Note the
weight of the appliance during installation.
ATTENTION
Risk of damage! Freezing water in the ap-
pliance can destroy parts of the appliance.
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.
 Check the wall's support capacity.
 Mark the wall using the drill template on
the packaging.
 Drill the bores into the wall.
 Attach the installation materials to the
wall.
 Remove the appliance cover.
 Hang up the appliance and secure it
against falling down.
 Replace the appliance hood and fasten
it with screws.

Electrical connection

– For connection values, see technical
data and type plate.
– The power supply designed for operat-
ing the plant must be suitable for contin-
uous operations.
– The electrical connections must be
done by an electrician according to IEC
60364-1.
– Current-carrying parts, cables and ap-
pliances in the working area must be in-
stalled in a defectless state and must be
protected against water sprays.
Water supply
– Design the water supply for continuous
operations.
– The water feed line is provided with a
stop valve and can be moved over a
pressure hose and attached to the high
pressure system.
– If the cross section of the line is too
small or if the advance pressure is too
low, there will be a lack of water.
– When the advance pressure or the
rinse pressure is too high, it is absolute-
ly necesary to install a pressure reduc-
er.
– A water drain must be present at instal-
lation site.
High pressure installation
For installation, please follow the specifica-
tions of the VDMA sheet 24416 "High pres-
sure cleaners; fixed high pressure cleaning
systems; concepts, requirements, installa-
tion, testing" (the German version can be
procured from Beuth Verlag, Cologne,
www.beuth.de).
– The fixed pipe network and the install-
ion should be connected with a high
pressure line.
– The fixed pipe network should be
placed as straight as possible. High
pressure piping systems should be in-
stalled correctly with removable and
fixed clips, taking into consideration the
variation in length caused by the effects
of heat and pressure.
– In order to keep pressure losses in the
high pressure piping as small as possi-
ble, we recommend the following:
Pipelines: Nominal width DN 15 (1/2").
Hose lines: Nominal width DN 8.
In regards to the above mentioned stand-
ard values, the length of the pipes and the
number of direction changes and fittings
must be taken into account.

Illustration, see "Operating components".
 Mount the nozzle on the spray lance
(marking on the adjustment ring at the
top) and hand-tighten it (EASY!Lock).
 Join the spray lance with the trigger gun
and tighten until hand-tight
(EASY!Lock).
 Join the high-pressure hose with trigger
gun and tighten until hand-tight
(EASY!Lock).
 Connect the high-pressure hose to the
high-pressure outlet of the device or the
high-pressure pipeline network
(EASY!Lock).
Install the detergent tank
The detergent tank is set up in such a way,
that the bottom of the tank is located not
more than 1.5 m unter the unit.
Initial startup
 Check that water inlet has the required
flow and the permissible temperature.
 Check oil level of the pump.
 Cut off tip of oil container.
