WARNING: Before unwinding or wind-

ing the hose, switch the machine o and release the pressure in the hose itself (switching o ). > WATER SUPPLY Water supply connection Caution - Danger! Only clean or ltered water should be used for intake. The delivery of the water intake tap should be equal to the double of the maximum pump range. Minimum delivery rate: 30 l/ min.- Maximum intake water temperature: 40°C- Max inlet water pressure: 1Mpa- Place the cleaner as close to the water supply system as possible. Water supply from the water main

• Connect a supply hose (not included) to the water inlet of the unit (ref. 1, pos.25) and to the water supply (max. pressure 10 bar).

• Connect high pressure hose to the ma- chine connection (ref. 1, pos. 3) and turn on the water tap. The cleaner can be connected directly to the mains drinking water supply hose is tted with a back ow preventer valve as per current regu- lations in force. Make sure that the hose is at least Ø 13 mm and that it is reinforced. Failure to comply with the above conditions causes serious mechanical damage to the pump and the los s of warranty cover.

> HIGH PRESSURE HOSE

WARNING: The high pressure hose is de-

signed and produced to withstand high pressures. To avoid damage, it must be handled with special care. Misuse may lead to premature breakages or damage and cause the loss of warranty cover. (See illustrations). > ELECTRICITY SUP PLY - The appliance’s electrical connection must comply with the IEC 364 standard.

Before connecting the appliance, make sure that the nameplate data are the same as those of the electrical mains and that the socket is protected by a di erential security breaker with tripping sensitivity below 0.03 A - 30 ms. - If the appliance’s plug is not compatible with the socket, have the socket replaced with another of suitable type by profes- sionally quali ed sta . - Never use the appliance in ambient tem- peratures below 0° C if it is equipped with a PVC (H VV-F) cable.

WARNING: Inadequate extension cords

can be dangerous. - If an extension lead is used, the plug and21

socket must be watertight and the cable must have the dimensions shown in the table below. (if tted) PLEASE NOTE: This water cleaner is equipped with the A.S.S. (Automatic Stop System), which stops the machine during the bypass phase. To start the water cleaner, it is therefore necessary to set the switch on position “ON”; after that press the pistol trigger: the Automatic Stop System will start the machine and will stop it automatically when the trigger is released. It is advisable to put on the safety of the pistol trig- ger whenever the machine is stopped, in order to avoid unintentional starting.

• Any automatic start of the machine with- out pressing the gun trigger is attributable to air bubbles in the water or other similar phenomena which do not imply the exist- ence of any defects in the machine.

• Do not leave the appliance unattended during the standby for more than 5 minutes. Contrarily, for the safety of the appliance it is necessary to re-turn the switch into the OFF position.

• Please check that the coupling of the high pressure hose with the appliance and the gun supplied as standard equipments made cor- rectly, that is to say without any water leak. If the appliance is equipped with a pressure regulator:

• when the pressure is set to minimum the A.S.S. may not trigger. Therefore, do not al- low the appliance to function in by-pass for more than 1 minute.

• do not act on the gun lever too frequently (this may cause a malfunction).

> INSTALLATION AND START-UP

WARNING: The installation of the unit

must be done only by an authorized and quali ed person who must follow and re spect the data present on the unit and for which it has been planned. The producer declines responsibility in case of non-observance of these rules.

START-UP When starting up for the rst time or after a long period out of use, connect the intake line only for a few minutes so that any dirt is vented from the delivery outlet. ELECTRICAL CONNECTION Check that the mains voltage is the same as that of your machine, indicated on the techni- cal data plate. Your electrical system must be constructed by quali ed technicians capable of working in accordance with the requirements of the regulations in force (earth connection, fuses, di erential security breaker, etc). In case of failure to comply with one of the regulations stated above, the manufacturer declines all responsibility for the sta and provides no warranty. IMPORTANT: Regarding three-phase motors, pay attention to the connection of the elec- tric cable to the plug (see electric diagram). START-UP Switch on the machine by pressing the switch (ref. 1, pos.4) and leave it to run for a few min- utes to eliminate any dirt and air bubbles from the water circuit, then switch it o , connect the high pressure line to the spray gun and t the spray rod . Make sure that the detergent regula- tor is in the closed position. When the machine is running again, check that the jet is even; otherwise, clean the nozzle to remove any dirt. Wait a few seconds for the op- erating pressure to be reached, then operate the gun for two or three short bursts. > LANCE ASSEMBLY To t the lance to the gun, it is su cient to in- sert the threaded end of the lance into the hole on the gun ; then screw the lance as shown by the arrow until the connection is tight. > DETERGENT SUCTION Fill up the detergent tank (not included) with the suggested products, suitable for the kind of washing to be carried out (ref. 1C, pos. 8). CAUTION: Make use only of liquid deter- gent, do not absolutely use acid or too much alkaline products. We suggest you to make use of our products, which have been studied for the use with washer ma- chines. CAUTION: For proper use of the tank, do not introduce ammable or chemically harsh substances. The adjusting head allow you to select water jet at low and high pressure. Pressure can be ad- justed by acting on nozzle knob . The selection of low or high pressure shall be carried out with gun in closed position. The detergent suction is automatic when the adjusting head of the lance is positioned for low pressure operation. When you start the machine, the mixing of the detergent with the water is automatic at the water passage.

> APPLIANCES PROVIDED WITH THERMAL

VALVE (OPTIONAL) This device enables the machine’s by-pass op- eration through automatic water discharge whenever it reaches a temperature of nearly 60°C and cooling working components. CAUTION: appliances that are not pro- vided with this disposal must not oper- ate for more than 2 minutes with released gun. Recycled water raises its temperature remarkably causing great damages to the pump.

Whenever the machine has to be stopped, it is important to engage the safety catch on the23

gun so that it cannot be operated accidentally. > MAINTENANCE IMPORTANT: Before doing any work on the cleaner, discharge the pressure and disconnect the electricity and water supplies

Check the oil level periodically. The oil must be changed for the rst time after 50 working hours, with subsequent changes every 500 hours. Use oil SAE 20/30 (750 gr).

CHECKING THE WATER INTAKE FILTER

Inspect and clean the water intake lter (ref. 9) on the intake union periodically. This is impor- tant to prevent fouling which may impair op- eration of the pump.

REPLACING THE SPRAY ROD NOZZLE

Replace the nozzle when the pressure drops below the normal values. ELECTRIC MOTOR If the motor malfunctions, it cuts out. Wait 5-10 minutes before restarting.
