Check the data plate on the machine. Make sure that the
machine's required power supply voltage and frequency
correspond to what is supplied by the mains.
WARNING
The power supply socket must be protected by a
differential circuit breaker that is in compliance with
current regulations.
7.3 ELECTRICAL SWITCH PANEL
The electrical switch panel is equipped with:
•
Main switch (a)
Operation/alarm warning lamp 1 - LED 1 (b) (only for ACDS
•
model): the warning lamp can be red, blue or green as described
in paragraph 7.7 "Signals".
7.4 START UP AND OPERATION
7.4.1 Start up
Fully open the water supply tap.
•
Rotate the SW switch from OFF to ON. The motor will turn on and
•
the pump will start rotating.
•
If no pressure is detected in the water circuit within five seconds
(presence of air to be purged), the machine will stop and show a
"no water" signal (both LEDs flash blue).
Rotate the SW switch from ON to OFF and wait 5 seconds to reset

the error.
•
Repeat the actions in point 3. It may become necessary to repeat
steps 3 through 5 before the circuit is full of water and free of air.
When the water shortage fault has been resolved, the machine
•
will be ready to work.
•
Disengage gun safety lock.
•
Squeeze the trigger on the gun to allow the delivery of
pressurized water.
WARNING
This machine is equipped with TSS, which allows
delivery to be stopped automatically:
• by releasing the gun, the electric motor will stop
after a 15 second delay;
• by opening the gun, the pressure drop will cause the
motor to start automatically and the pressure to
recover with a very slight delay.
For the TSS to function properly, the gun closing and opening
operations must not be carried out in a time interval of less than 4-5
seconds.
7.4.2 Stop
Cold water
Rotate the SW switch from ON to OFF.
•
Open the gun and release the pressure inside the piping.
•
Click the gun safety lock to safe
•
7.4.3 Restarting
Cold water
Disengage gun safety lock.
•
Turn the SW switch from OFF to ON. The motor will turn on and
•
the pump will start rotating.
•
Squeeze the trigger on the gun to allow the delivery of
pressurized water.
7.4.4 Shutdown
Cold water
Close the water supply tap
•
•
Continue working to completely empty the machine's water tank

and the water in the pump.
•
When the machine is completely empty, rotate the SW switch
from ON to OFF.
Unplug the machine from the power mains.

7.5 OPERATING PROCEDURES
The MAXIMA / MAXIMA PLUS / XTFOOD series high pressure
washers are equipped with a "delayed total lockout system", which
stops the machine a few seconds after the gun is released. Pressing
the gun again will cause the machine to restart normally.
The high-pressure cleaner is equipped with a "micro leak detection"
function, which will stop the machine after repeated starts caused by
small leaks. If this function is tripped, the machine will stop. To
restart it (reset), first rotate the main switch to "OFF" and then back
to "ON"
The high pressure washer is equipped with a "time-out" function,
which stops the machine after 20 minutes of inactivity. If this
function is tripped, the machine will stop. To restart it (reset), first
rotate the main switch to "OFF" and then back to "ON" This function
can be excluded but this operation is to be carried out only by expert
personnel.
7.6 PRESSURE CONTROL VALVE
The pressure control valve allows the water pressure to be reduced
from its maximum value down to about 25 bar. Reducing this value,
the valve partializes the quantity of water.
7.7 SIGNALS (ONLY ACDS MODEL)
