4 CONNECTION OF THE WATER SUPPLY PIPE
Based on the prescriptions and provi-
sions set forth by the regulations currently
in force, it is mandatory that the appliance
is never operated without a potable water
backflow preventer device, connected up to the
potable water supply mains. Use a suitable potable
water backflow preventer device, compliant to the
EN 12729 type BA standard provisions. Water that
flows through a system backflow preventer cannot
be classified as potable water.
Connect a clean water supply pipe to
the water mains, checking to ensure that
the minimum pressure is of 1.5 bar and
maximum is of 6 bar, with a minimum
flow rate of 7 l per min.
-
Connect the water supply pipe (min.
diam ½") to the water mains (fig.4)
- Screw the male connector (1 - Fig. 5) on to the at-
tachment of the water supply (2); snap the female
connector of the tube (3) on to the connector.
5 HIGH PRESSURE PIPE CONNECTION
- Unwind the pressure hose off the hose drum (Fig.
6).
- Screw the high pressure tube on to the gun
(Fig.7).
Assembly of the detergent spraying device
- Insert the nozzle and tighten the threaded locking
ring on the gun. (Fig. 8).
6 ELECTRICAL CONNECTION OF THE AP-
PLIANCE
The mains voltage must match the operating volta-
ge. (See identification plate)
Insert the plug into a power socket installed in
compliance with regulations.
Check the minimum section of the individual cables
using extensions.
Position the extensions so as to maintain the pro-
tection class of the equipment.

7 APPLIANCE ACTIVATION
Operate the equipment in vertical po-
sition (fig.9) only after connecting the
water supply pipe and turning on the tap.
- Position the switch on I (ON) (Fig.10).
- Position the spray gun on the object to be
cleaned - never on people !
- Press the safety device (1-Fig.11) - the gun is
released
- Direct the nozzle downwards (Fig.9)
- Fully press down the trigger (2 Fig.11)
- Position the switch on O (OFF) (Fig.10).
- Turn off water supply tap.
-
- Release trigger.
- Press safety latch on spray gun. (1 Fig.11). The
- Unplug machine from socket outlet.
- Disconnect water supply hose from machine and
Variable nozzle
The nozzle (12 - Fig.1) can be regulated in a
continuous manner, by rotating the regulation
bushing, changing it from a pinhole jet (Fig.12) to
a flat jet and viceversa.
It can be used at either high or low pressure by
shifting the head in a longitudinal sense according to
the direction of the arrow on the head itself (Fig. 13).
ADDITION OF DETERGENT
The product is fitted with two detergent tanks.
Thedetergent adjustment knob (Fig. 15) is used to
switch thesuction between detergent tanks (Fig. 16)
and increase/de-crease detergent flow.
Fill the machine tanks with detergent (Fig. 14) taking
care to dilute it according to the instructions. To fa-
cilitate the filling and emptying operations, the tanks
can be removed from their housings.
Winder kit
The rotation sense for the winding of the high pres-
sure hose is only permitted in a clockwise direction.
(fig. 17). It is possible to prevent rotation by using the
lever (1) situated on the back of the handle (Fig. 18)

vided with the "pressure regulating" device.
The pressure regulator, fig. 20, allows the operator
to adjust the working pressure. When knob C is
turned in an anti-clockwise direction (B) (minimum),
the working pressure is reduced.
Undertake only the maintenance operations descri-
bed in the user instructions.
