high-pressure hose of the combined high-pressure cleaner.
• Make sure the master switch (1) is in "0" position and insert the plug. Operation H in Fig. 7.
• Making reference to the indications in the relative instruction manual, connect the combined high-pressure
cleaner to the power supply line, making sure the cleaner is in stop condition.
• Open the water supply tap (in case of connection to the drinking water mains, a water disconnector
must be used: for its use, refer to the relative instruction manual), making sure there is no dripping (or
introduce the suction pipe into a supply tank).
• Making reference to the indications in the relative instruction manual, start the combined high-pressure
cleaner.
• Press the lever of the spray gun (31) and wait for a continuous jet of water to come out.
• Making reference to the indications in the relative instruction manual, stop the combined high-pressure
cleaner.
• Making reference to the indications in the relative instruction manual, connect the spray gun to the lance
hose (33).
• Unscrew the cap (7) and, making sure there is no liquid overflow (it is best to use a funnel used for this
purpose only), fill the tank (max capacity 18 l/4.8 US gal for the HOTBOX 15/200; 20 l/5.3 US gal for other
models) with diesel fuel; screw the cap back on.
STANDARD OPERATION (HIGH-PRESSURE WITH HOT WATER)
• Making reference to the indications in the relative instruction manual, start the combined high-pressure
cleaner again.
• Start the equipment by moving the master switch (1) to
on the control panel.
• Turn the temperature adjustment knob (16) to select the desired temperature.
• Press the lever of the spray gun and make sure the nozzle spray is uniform and there is no dripping.
• In case of lack of diesel fuel, the burner stops and the indicator (18) lights up.
• The burner starts after about three seconds from when the spray gun is opened and stops operating
when the spray gun is closed or when the set temperature has been reached.
• In case of the flame going out the burner stops and the indicator (20) lights up.
• To interrupt hot water operation, move the temperature adjustment knob (16) to "0" position.
CAUTION
Before completely switching off the equipment, allow it to run for a few minutes with cold water, moving
the temperature adjustment knob (16) to "0" position. This will enable the boiler to cool down.
STEAM OPERATION (MAX PRESSURE 32 BAR - 464 PSI)
This equipment has been designed to comply with category II of Directive 97/23/CE relating to pressure
equipment (PED). Such compliance is achieved by means of a special electronic device able to constantly
check:
• that with temperatures above 110 °C/230 °F, the set pressure is below 32 bar/464 psi;
• that for pressures above 32 bar/464 psi, the set temperature is not higher than 110 °C/230 °F.
If such limits are exceeded, burner operation will stop and the indicator (19) lights up.
Steam operation can only start again if the pressure is lowered below 32 bar/464 psi.
• With reference to the indications in the relative instruction manual, start the combined high-pressure
cleaner again and lower the pressure to below 32 bar/464 psi.
• Start the equipment by moving the master switch (1) to
on the control panel.
• Turn the temperature adjustment knob (16) so as to select the required temperature within the field
110 °C/230 °F - 140 °C/284 °F.
• Press the lever of the spray gun, to release the steam.
• If, during operation, the burner stops and the indicator (19) lights up, lower the pressure on the combined
high-pressure cleaner until this is below 32 bar/464 psi.
• In case of lack of diesel fuel, the burner stops and the indicator (18) lights up.
