ENGLISH
- Safety valve and/or pressure limiting valve.
The safety valve is also a pressure limiting valve.
When the gun trigger is released, the valve
opens and the water recirculates through the
pump inlet or is discharged onto the ground.
- Thermostat valve (D1 where fi tted) If the water
temperature exceeds the temperature set by the
manufacturer, the thermostat valve discharges
the hot water and draws in an amount of cold
water equal to the amount of water discharged,
until the correct temperature is restored.
- Safety catch (D): prevents accidental spraying
of water.
- Overload cutout: stops the appliance in case of
overload.
INSTALLATION (FIG.2)/PAGE 3
Assembly
Warning - danger!
All installation and assembly operations
must be performed with the appliance
disconnected from the mains power
supply.
The assembly sequence is illustrated in
fi g.2.
Fitting the pressure release caps (on models
with this feature)
To prevent oil leaks, the appliance is delivered with
the oil intakes sealed with red caps which must be
replaced with the pressure release caps supplied.
Fitting the rotating nozzle
(For models with this feature).
The rotating nozzle kit delivers greater washing
power.
Use of the rotating nozzle may cause a reduction in
pressure of 25% compared to the pressure obtained
with the adjustable nozzle. However, the rotating
nozzle kit delivers greater washing power due to
the rotation of the water jet.
Electrical connection
Warning - danger!
Check that the electrical supply voltage
and frequency (V-Hz) correspond to
those specifi ed on the data plate (fi g.2).
Use of extension cables
Use cables and plugs with "IPX5" protection
level. The cross-section of the extension cable
should be proportionate to its length; the longer
it is, the greater its cross-section should be. See
table 1.

Water supply connection
Warning - danger!
Only clean or fi ltered water should be
supplied to the appliance. The fl ow rate
of the water inlet tap should be equal to
the pump fl ow rate.
Place the appliance as close to the water
supply system as possible.
Connection points
● Water outlet (OUTLET)
■ Water inlet with fi lter (INLET)
Connection to the mains water supply
The appliance may only be connected directly to
the mains drinking water supply if the supply hose is
fi tted with a backfl ow preventer valve as per current
regulations in force. Make sure that the hose is at
least Ø 13 mm, that it is reinforced and that it is not
more than 25 m long.
Suction of water from open containers
1) Screw the inlet hose with fi lter to the water INLET
and insert it down to the bottom of the container.
2) Vent the air from the appliance:
a) Unscrew the lance.
b) Start the appliance and keep the gun open
until there are no air bubbles in the water
fl owing out.
3) Switch the appliance off and screw the lance
back on.
N.B.: the maximum suction height is 0.5 m. The
suction hose should be fi lled before use.
ADJUSTMENTS (FIG.3)/PAGE 4
Adjusting the spray nozzle (for models with this
feature)
Water fl ow is adjusted by regulating the nozzle (E).
Adjusting the detergent
To deliver detergent at the correct pressure, set the
nozzle (E) (where fi tted) on " " or fi t the detergent
kit (C13) (where available) as shown.
The quantity of detergent delivered is adjusted using
the regulator (F).
Adjusting the working pressure (on models with
this feature)
The regulator (G) is used to adjust the working
pressure. The pressure is shown on the pressure
gauge (where fi tted).
