Using the inductor
1. By hand or with the use of a coupling spanner, connect the adapter
of the pump-side hose (Fig. 3/
1
) to the fixed coupling on the inlet
side (Fig. 3/
2
).
2. By hand or with the use of a coupling spanner, connect the adapter
of the tube-side hose (Fig. 3/
6
) to the fixed coupling on the outlet
side (Fig. 3/
5
).
3. Adjust the setting sleeve (Fig. 3/
4
) to the required admixing rate.
4. Connect the pick tube to the inductor (Fig. 3/
3
) and insert it into the
foam mixing container.
5. Connect and close the required foam nozzle.
6. Carefully fill the hoses with water and pressurise.
7. Open the foam nozzle and regulate the pressure at the pump until
the required pressure (medium expansion foam 3 – 4 bar, low ex-
pansion foam 5 – 6 bar) is present at the foam nozzle.
Rinsing and uncoupling the inductor
1. Shut off the water supply.
2. Interrupt the supply of foam agent.
3. Open the water supply and the hand lever at the foam nozzle.
4. During rinsing, switch the setting sleeve through all settings in order
to ensure that all internal suction bores are cleaned.
Important
Do not aspirate dirty water or foam concentrate to en-
sure that the suction holes do not get clogged.
5. As soon as only clear water and no more extinguishing foam
emerges from the foam nozzle, close the hand lever. If necessary,
perform multiple rinsing passes.
6. Shut off the water supply and, by hand or with the use of a coupling
spanner, detach the input and output side couplings from the fixed
coupling.
Important
Water may emerge when the coupling is released.
