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.
