Connection to water supply: FAUCET.inlet.
Use a quick coupling or a firefighter coupling (also called GEKA) with 3/4" thread.
In accordance with the EN1717* standard
No High pressure cleaner can be connected to the drinking water supply EXCEPT if it is
equipped with an anti-backflow device (so called "BA Valve").
Additionally, the length of the water supply hose must be of at least 12 m (minimum
Ø 19.1 mm) in order to regulate possible pressure peaks in the network.
* Failure to comply with this standard is the sole responsibility of the user; in no way can the
manufacturer or distributor, whose sole responsibility is to issue the warning ,be held responsible
for failure to comply.

About the ASSEMBLY / DISASSEMBLY of the accessories:
DO NOT TIGHTEN TOO MUCH!
The female coupling of the hose is fitted with a spigot which has an o-ring to ensure
watertightness, the latter is hence garanteed even with low tightening torque.
DISCHARGE PRESSURE BEFORE GOING ABOUT ANY CHANGE OF
ACCESSORY!
Under pressure, it is difficult to untighten the coupling by hand and this results in damage to the
seals
To discharge pressure: Turn the device off and simply press the trigger.
All the accessories have a universal M22 coupling : As this is the norm on the HP market, you will
be able to fit your device with additional tools, keeping costs to a minimum
