Water connection
Two water connections have been envisaged
on the machine.
The main connection
(1)
supplies the water
needed for mixing.
The secondary connection
(2)
is for cleaning
the machine.
The machine is equipped with a water pump for setting sufficient pressure,
independent of the pressure of the water supply connection.
A rubber hose (at least 10 bars) at least ¾“ in diameter must be
used as a connecting hose. It is necessary to check the
compatibility of the attachments to the hose and the machine
before connecting the hose. Unsuitable connections must be
replaced by suitable ones.
A filter to avoid contamination must be installed
at the entrance of the water. The filter must be
cleaned regularly and replaced if damaged.
In the case of particularly dirty water we also recommend
cleaning the filter several times during the day.
Damaging the machine!
Damage because of particles of dirt can occur if the filter is not
used. Inobservance forfeits any possible guarantee.
Connect the hose for the water supply
(B)
of
the machine to an external tap and expel
the air. To do this it is necessary to leave the
unloading valve open until there are no
bubbles left in the hose.
The pressure of the water entering must be at least 3 bars. If this
amount of pressure is not guaranteed (check the plant water
pressure
(A)
), it is necessary to use an overpressure pump with
the following characteristics between the water input and the
machine:
x
Maximum flow pressure (water column 42 m)
x
Maximum capacity 45 l/Min.
