10.2 WATER CONNECTION

Connect the water hose (table 1) to the water mains (fig.6).
The water mains must guarantee a minimum flow rate of
20l/min.
Otherwise a tank of suitable capacity (200 l) must be fitted with
clean water, to be kept full at all times, and from which water can
be taken by means of the self-priming pump supplied with the
machine. In this case the hose must have a minimum diameter
of 3/4", a maximum length of 3m, preferably a foot filter and must
not be subject to deformation during use.
- Caution! The first time the water pump
is connected to the tank, it must be activated by manually
filling the intake line.
The same operation must be repeated each time the circuit is
drained, or after a prolonged period of disuse.

10.4 AIR CONNECTION

Connect the air hose to the machine panel and spray jet (fig.7)
11. START-UP
Close the air valve (ref.9a) supplying the spray jet (fig.10).
Open the micrometric valve (ref.8) virtually fully.
Turn the main switch/inverter (ref.1a) to position 1 or 2: in the
correct position the blue "phase correct" lamp illuminates (ref.1g).
Check that the water pressure gauge (ref.11) indicates a minimum
pressure of 3.5 bar and that the green "no water pressure" lamp
(ref.1i) is off. Otherwise, activate the pump by means of the water
pump switch (ref.1f). Press the water supplement pushbutton
(ref.1d) for 3-4 seconds.
Start the pump by means of the start pushbutton (ref.1c):
the lamp on the start/stop pushbutton illuminates and the mortar
pump starts up for a few seconds.
Open the spray jet air valve: the machine starts up. Check that the

water pressure does not fall below 2.5 bar; otherwise activate the
water pump. Use the micrometric valve to regulate the water flow
rate, displayed on the flow meter (ref.2) with respect to:
- 800l/min if using gypsum based materials (pump D 6-3).
- 500l/min if using cement based materials (pump D 6-3).
Start the cell wheel by means of the relative switch (ref.1e) and
then stop it.
Close the air valve.
Fill the hopper with dry materials.
Open the air valve of the jet. Activate and deactivate the cell wheel
3 or 4 times by means of the relative switch
(2 -3 seconds operation, 2-3 seconds stopped) and then switch
on permanently. Regulate the water to obtain the consistency as
recommended by the material manufacturer. Close the air valve to
the spray gun. Check the material hoses to ensure perfect condi-
tion, that couplings are intact and the relative seals are fitted, and
pour approx. 3 litres of grout in the first section and then connect
them to the delivery manifold (ref.10) and spray jet. Check that
the cam levers ( A ) of the couplings have been tightened correctly
and that the seal
( B ) is fitted as shown in fig.8.

Start the machine: when the correct consistency of material is
delivered from the jet normal operation can be started.
The machine starts and stops by opening and closing the air
supply to the spray jet.
The machine is fitted with protection against power failure and
water pressure failure: if one of these occur, press the start pu-
shbutton to resume operation.
To stop the machine in the event of an emergency, press the red
emergency pushbutton (ref.1b) to shut down the machine - all
moving parts are shut down - and then turn the main switch to 0
and remove the electric power plug from the socket (ref.1l).
