9. Connection to the water supply
9.1. The pressure of the water supply must be at least 2 bar. If the pressure is insufficient, the pump
will inhale air and will be subject to overheating and vibrations with serious damages to the
pump and the car.
9.2. The water supply must provide a flow of water of at least of the 10% of the course of the high
pressure cleaner (compare the chart with technical characteristics).
9.3. First of all, connect the water supply tap to the machine input pipefitting IN, using a hose with
proper diameter, whether to connect the lance to the link of exit OUT.
9.4. For a long duration of the pump, and to avoid the use of water containing sand or other particles
that jeopardize the efficiency of the valves and of the pistons or of the gaskets. To such purpose
it is advisable to apply a filter to the pipe of suction to great surface and low loss of load,
handling periodic substitution.
9.5. When the machine is equipped with a special tank, it is convenient to install a filter upstream of
the tank: the pipe of water feeding must have a diameter not smaller than the link of the
connection to the machine and must be prepared in such way to avoid that possible airlocks are
formed.
9.6. The water supply can have a maximum temperature of 60°C and a maximum pressure equal to
8 bar. The gaskets and other parts and components of the pump could be irremediably
damaged when the machine is made to work without of water, even if for short periods. Verify
that the tap of the water supply is completely open before the high pressure cleaner is switched
on.
OPERATION
10. Switching on
10.1. To bring the interrupter in position 1 and to maintain the thermostat to the least (rotated
counterclockwise in sense) one.
10.2. To act on the trigger of the gun (hilt) on the lance, maintaining her/it with strength to
compensate its counterblow and making to work the car for 2 or 3 minutes: this allows to bait
the pomp and to eliminate possible residues that could clog the nozzle; The trigger of the gun
has a sure that prevents the accidental activation of the throw. To insert the sure one when the
lance is not used. In this condition the car works to cold water.
10.3. In the case in which a detergent is used, to insert him/it in the reservoir on purpose predisposed
to the purpose and to open the faucet.
10.4. For the water operation warm, to rotate the thermostat to regulate its temperature.
10.5. To press the interrupter.
11. Switching off
11.1. By releasing the trigger of the gun, the jet of water interrupts and the machine stops, remaining
however turned on and available to the use: to stop therefore the safety catch on the trigger.
11.2. To switch definitely off the machine, turn the switch on O; if the machine has worked with hot
water it is opportune, before switching off the switch, to lower the temperature, that is to rotate
on 0 (in sense counterclockwise) the thermostat and letting work the high pressure cleaner with
cold water for about 2 minutes, to cool the coil.
11.3. For prolonged stand-by, before turning off the machine, it’s necessary to cool the coil as
previously clarified: close therefore the tap of the water supply, operating on the trigger, so that
to unload completely the water from the circuit. This procedure is advisable especially in places
with temperatures go under zero.
11.4. As soon as the water flow stops, switch the machine off by acting on the switch.
11.5. ATTENTION: the operation of the pump in absence of water could irreparably damage the seals
of the pomp.
