3. Design/Fuction/Illustrations
The cold water high pressure cleaners of this series mainly comprise a
low speed high pressure inline plunger pump which is directly flanged to
an high efficient, 100 % duty cycle electric motor.
The feed water is directed with the necessary admission pressure via a
filter into the high pressure pump, forwarded to the spray nozzle and so
boosted to working pressure.
Downstreams of the high pressure pump a safety/control valve is
arranged which opens in case the max. operating pressure is exceeded
by more than 10 % and returns the water which cannot be taken by the
nozzle into the suction line of the high pressure pump.
The machine is equipped with a circulation safety cut-off and additionally
with a thermo valve in order to protect the high pressure pump against
overheating. When closing the spray pistol, the safety/control valve
opens and returns the circulating water into the suction line of the high
pressure pump If in this operating mode the water temperature exceeds
60 °C, the thermo valve opens, releases hot water and allows cold
water to enter. When activating the spray pistol again, adjusted working
pressure is generated immediately so that the cleaning task can be
continued without delay.
The range of applications can be extended by a variety of accessories
available from OERTZEN. Contact your local distributor.

Connections
Water Supply
Connect water inlet (6) of the machine to water source with a clean hose
(diameter see table below). Before connecting water supply hose, rinse it
thoroughly. In case of connection to the potable water distribution, observe
DIN 1988 (for momentary connections use a backflow preventer with non-
return function and ventilation).

Power Supply
Insert plug into a 440 V socket which is protected by 3 x 63 A (slow). Only
extension cables designed according to VDE to be used. Extension cables on
reels to be reeled off during operation in order to avoid overheating of the reel.
Plug, couplings to be watertight. A faulty current protection switch to be added.
VDE regulations to be observed.
High Presure Connection
Connect high pressure hose to high pressure outlet (11) by means of the
union without using tools.
Pipe Cleaning Connection (optional)
Connect high pressure hose to high pressure outlet without using tools. Mount
required pipe cleaning nozzle on the other end of the high pressure hose
(handtight, without using tools).
Operation
•Fully open water source
•Push ON/OFF switch (2).
The electric motor starts in star connection and switches over to star-delta
connection after a few seconds. This process is audible. After the electric
motor has switched over to star-delta connection:
•Unlock spray pistol, firmly seize support handle.
•Open spray pistol.
•Carry out cleaning task.
Observe torque and recoil, as well as shortening of high pressure hose.
Ensure stable foothold.
When opening the spray pistol, full working pressure is achieved within a few
seconds. At 500 bar the high pressure hose shortens by approx. 3 %.
Particularly when working with extra long hoses or on scaffolds, take care that
operators will not be jeopardized.
When closing the spray pistol, the safety/control valve opens
and returns the circulating water into the suction line of the
high pressure pump If in this operating mode the water
temperature exceeds 60 °C, the thermo valve opens, releases
hot water and allows cold water to enter.

High Pressure Pipe Cleaning (Option)
During pipe cleaning aerosols may be generated, a protecting mask to be
worn.
Push pipe cleaning hose with nozzle to be pushed into the pipe until the mark
(approx. 50 cm) is reached. Open Stop valve and start high pressure cleaner
by means of the ON/OFF switch (2). The recoil effect automatically draws the
nozzle into the pipe. As soon as the nozzle reaches the blockage, carefully
draw back pipe cleaning hose and let it be drawn in again. Work carefully in
sections in order to gradually remove the blockage in order to avoid clogging
of the pipe cleaning nozzle (risk of further blockage).
When removing the pipe cleaning hose, stop machine as soon as soon
as approx. 50 cm of the hose are still in the pipe (mark), in order to avoid
uncontrolled flapping of the hose which may cause severe injuries. If
there is no mark can be detected, it should be fixed with tape or paint.
