2.2 Safety Devices

This water cleaner is provided with the following safety devices:
a) Amperometric protector
It is a device that is built in the switch (2) that stops the water cleaner operation in case of current over-
absorption, thus making the switch itself trigger to position "0".
When it triggers, it is necessary to proceed as follows:
- remove the plug from the power socket;
- press the lever (24) of the water gun, in order to evacuate the possible rest pressure;
- wait 10÷15minutes, so that the water cleaner cools down;
- check the prescriptions described in paragraph "Checks and Connection to the Mains Electricity
Supply", with special reference to the check of the possibly used extension;
- reconnect the plug into the power socket and repeat the starting procedure described in paragraph
"OPERATION".
b) Safety valve
It is a maximum pressure valve that is duly calibrated by the Producer and that discharges the pressure
in excess, in case of failure to the pressure and/or temperature adjusting system.
WARNING
• If this safety device cuts in repeatedly, do not use the water cleaner until it has been checked by a Skilled
Technician.
c) Pressure limiting/adjusting valve
It is a valve that is duly calibrated by the Producer and that avoids the generation of pressures that are
higher than the maximum allowed ones, thus making the fluid in excess flow back to the pump suction.
d) Temperature limiting/adjusting thermostat
It is a device that avoids to overcome the maximum temperature.
e) Water missing protection
It is a device that prevents the burner from operating in case of water absence.
f) Locking device of the water gun lever
It is a safety stop (25) that allows to block the lever (24) of the water gun (16) in closing position, thus
preventing accidental operations (see picture 1, position S).
