4.2 Functionality
The mixing pump is filled with powdery material, for in-
stance, bagged goods. The mixing coil and pump unit (ro-
tor/stator) are directly driven by a gear motor. During oper-
ation, the powdered material is conveyed from the material
hopper over the star feeder into the mixing zone, − where it
is mixed with water with the mixing coil − to form a homo-
geneous, paste-like product. The pump unit (rotor/stator)
attached at the lower end of the mixing zone conveys the
mixture through flexible conveyor hoses to the spray gun
or glue gun. The machine is controlled either pneumatically
(via the air valve on the spraying device or electrically via a
remote control cable laid from the switching cabinet to the
spraying device. Here, the machine is controlled by an on/
off switch.
NOTE

If the machine control is to be changed
from electric to pneumatic, the dummy plug must be
plugged into the Harting plug of the switching cabi-
net.

mote control.
• When the remote control cable is plugged into the
switching cabinet, the machine is switched on and off
via the green push button at the end of the remote
control cable.
4.4.1.2 Star feeder selector switch
There are two settings:
• 0 = OFF: This setting switches off the star feeder motor
and interrupts the material supply to the mixing zone.
• 1 = AUTOMATIC: This setting couples the star feeder to
the working cycle of the mixing pump. The star feeder
rotates as soon as the pump motor is switched on.
4.4.1.3 Start / stop button
1. Press the green start button (“I”) to start the mixing
pump.
2. Press the red stop button (“0”) to stop the machine.
4.4.1.4 Phase-change switch with locking button
The phase inverter adjusts the direction of rotation of the
machine to the power grid on site.
1. Set the main switch to “0” (horizontal).
2. Turn the phase inverter in the opposite direction of its
current position and hold down the locking button be-
low the phase inverter switch.
!
DANGER The phase inverter may only be operated
when the machine is switched off. To do this, turn
the main switch to “0” (horizontal).
4.4.1.5 “Water supply” push button
This push button is used for the manual water feed.
• Pressing this button adds extra water to the mixing
zone if required. Keep the push button pressed until
the desired amount of water is added.

4.4.2 Mixing pump unit (motor, mixing coil, rotor/sta-
tor and mortar pressure gauge)
The mixing coil is connected to the motor via the drive shaft
and rotates during operation in the mixing zone. The mixing
coil is also connected to the rotor via a plug-in connection.
The mixing coil can be pulled out for cleaning and mainte-
nance work. Before removing the mixing coil, switch off the
machine and pull out the mains plug. The choice of mixing
coil (see accessories) depends on the planned application.
The mortar pressure gauge is used to monitor and display
the pressure in the conveyor hose.
This image illustrates the connection from the motor to
the mixing coil, and from the mixing coil to (rotor/stator).
Power is supplied to the motor via a plug-in connection to
the machine’s switching cabinet.
!
DANGER Rotating mixing shafts.
Danger of death due to being pulled into the ma-
chine and crushed.
When the motor is running, the mixing shaft rotates
in the mixing zone!
• Do not reach into the rotating mixing shaft.
• Do not place any objects into the rotating mixing shaft.
1. Before working on the metering and mixing shaft, inter-
rupt the external power supply (main switch off).
2. Pull out the mains plug.
3. Secure the machine against unexpectedly being switched
back on.
4. Open the eccentric lock on the motor and move it away
to the side.

4. Connect the external water hose to the GEKA coupling
of the water fitting (11).
5. Close both the water drainage valve below the pressure
reducer (5) and below the main connection (12).
6. Connect the internal water hose to the GEKA coupling
on the mixing zone.
NOTE

To ensure sufficient water pressure regard-
less of the pressure of the supply line, the machine is
equipped with a pressure booster pump.
!
WARNING Water jet.
Risk of injury and risk of property damage due to es-
caping water.
1. Interrupt the external water supply by closing the water
valve.
2. In order to release the pressure (approx. 2 bar), open
the water drainage valve on the water measuring sys-
tem under the pressure reducer.
3. Only remove the hose from the external water supply
when the pressure gauge shows “0” bar.
4. Do not point the water jet at other people or yourself.
4.4.5 Air fitting
1. Use the air connection (1) to supply a sprayer.
2. Check that the connections fit together before con-
necting the air hose. If necessary, replace them with
suitable connections.
3. The pressure switch (2) is pre-set at the factory and
switches the machine on and off.
