Operation
5.2 Injection
Prerequisites:
➤
The machine has been put into operation.
➤
The required packer nipples are attached at the points to be injected.
1.
Turn the compressed air regulator for the proportioning pumps down
completely.
2.
Set the one-hand lever of the mixing unit to "Stop".
3.
Connect the coupling piece on the material outlet of the mixing unit to the
packer nipple.
4.
Set the one-hand lever of the mixing unit to "Injection".
5.
Set a low air inlet pressure on the compressed air regulator for the
proportioning pumps.
6.
Start the injection with an as low of a pressure as possible so that the
safety of operating personnel and masonry is not endangered.
7.
Slowly increase the pressure to the desired working pressure.
8.
Set the one-hand lever of the mixing unit to "Stop" after the injection
process is completed.
Observe the fill level of the material drum during injection. Refilling the ma-
terial in a timely manner prevents the pumps from suctioning air and thereby
having to vent the unit.
9.
Switch to the next packer within the pot life of the material used and repeat
work steps 3-7.
10.
Flush the mixer block immediately after completing the last injection
process until clean cleaning agent runs out.
Always observe the pot life of the material used!
5.3 Checking the injection pressure
Check the function of both proportioning pumps by repeatedly opening and
closing the one-hand lever of the injection lance. Observe the material pressure
display on the pressure gauges while doing so:
➤
Both pressure gauges must always display
the same values!
➤
If the one-hand lever is closed during
injection, an equally high dynamic pressure
is displayed on both material pressure
gauges.
➤
The values must go back to the working
pressure when the one-hand lever is
opened again.

If this is not the case, shut down the machine immediately and check the
machine or contact WIWA customer service.
