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
