3) Make sure that all components are properly installed.
4) Make sure that the main electric switch is in pos. “0” (off).
5) Make sure that the safety devices are integral, properly installed and
working.
6) Make sure that all shelves are correctly closed.
7) Make sure that the service taps and the system water drain are closed.
8) Make sure that the valve of the spraying nozzle is open.
9) Make sure that the plug of the power supply cable is connected to the plant
supplier and that the main electric switch is off.
10) Make sure that the air, water and material conveying tubes are well
stretched avoiding any constriction.

13) Verify the filter presence, if the water isn’t being drawn from water supply.
Manual instruction Mixer Plus Mixer Technology srl pag.22
Page 23
MACHINE PREPARATION
1) Supplies voltage to the electric panel.
2) Don’t let unattended on the machine.
3) Control of water flow rate in the mixing chamber:
a. Disconnect the water tube incoming in the trunket
1. If the pressure indicated from the gauge is lower than 4 bar,
position the water pump selector on “Manual”
2. If it is greater than 4 bar, position the water pump selector on
“Automatic”
b. Open the water solenoid valve enabling the selector marked by the
symbol “tap with drop” on the flow meter (fig. 1-26) check the water
flow rate
c. Set the water flow rate suggested: Cement type: 600 litres/min –
Gaseous type: 1000 litres/min
d. Connect the inlet water pipe of the mixing chamber inlet (To avoid
starting the machine in "idle" status, it is necessary to let a
minimum quantity of water (0.5 litres) enter the mixing chamber)
e. Open the water for at least 6 s.
4) Loading of the product:
a. Load the pre-mixed products on the hopper
b. Cutting them at the bottom with the cutting blade
c. Flow the product inside the hopper
5) Preparation of mixture:
a. Disconnect the material conveying tube from the machine material
output connection pulling the side levers (fig.1-28)
b. Position the water pump selector on “Automatic”;
c. Start the cell wheel;
d. Start the mixing;
e. Increase or decrease the water flow rate incoming in the trunket acting
on the related adjustment valve till obtaining the wished consistency;
f. Stop the machine;
g. Open the service tap (fig.1-18) to perform the internal wetting of the
material conveying tube; when the water comes out from the tube
close the tap and disconnect the tube;
h. Connect the material conveying tube to the machine material output
connection;
6) Plaster pressure regulation:
The pressure of the material at machine output determines the duration of the
stator (plenum chamber) and of the rotor (screw).
Manual instruction Mixer Plus Mixer Technology srl pag.23
Page 24
The recommend pressure depend from plaster types and from the second tube length
according to the following scheme:
o Cement type = 1 bar/metro
o Gaseous type = 0,8 bar/metro
Example: for processing gaseous type with the 15 meters tube the maximum
recommend pressure is 15 x 0,8 = 12 bar.
IT’S ABSOLUTELY FORBIDDEN TO USE THE MACHINE WITH MATERIAL
OUTPUT PRESSURE VALUES GREATER THAN 20 BAR
Manual instruction Mixer Plus Mixer Technology srl pag.24
Page 25
SPRAYING OF THE MATERIAL
1) Hold the spraying nozzle and direct it against the surface to be plastered;
2) Open (+) the valve on the spraying nozzle;
3) Adjust the spraying of the material moving forwards and/or backwards (+ or -),
the air tube acting on the screw and blocking it in the correct position;
4) To minimize the deterioration of stator/rotor group, avoid useless stops and
restarts of spray;
5) During work breaks less than 15 minutes, close the valve on the spraying
nozzle. For longer breaks must be execute the shutdown process;
6) In case of clogged of material conveying tube, enabling the mixer reverse run
selector for the time needed;
MACHINE SWITCHING OFF
1) Stop the cell wheel;
2) Continuing the spraying till from the spraying nozzle just water;
3) Closing the valve on the spraying nozzle;
4) Stop the mixing chamber;
5) After every shutdown, carry out the machine cleaning;
